C. State whether the following statement are true or false with reasons.

Question 1.
Gain ratio means New ratio minus Old ratio.
Answer:
This statement is True.
As per definition, profit sharing ratio which is acquired by the continuing partners from the retiring partner is called gain ratio. If gain ratio added to old ratio we will get New ratio. It means New ratio = Old ratio + Gain ratio by interchanging the terms, we will get Gain ratio = New ratio – Old ratio.

Question 2.
Retiring partner’s share in profit up to the date of his retirement will be debited to Profit and Loss Suspense Account.
Answer:
This statement is True.
If a partner retires from the firm during the accounting year, the profit or loss for the period from the date of last balance sheet to the date of retirement is calculated on the basis of last year’s profit or average profit and it is credited to retiring partner’s capital A/c and for time being it debited to new account called Profit and Loss Expense A/c. This is because final accounts cannot be prepared on any date during the accounting year.

Question 3.
On retirement of a partner, sacrifice ratio is considered.
Answer:
This statement is False.
On retirement of a partner, his share is acquired by continuing partners in certain proportion and it is nothing but gain for them. Therefore, on retirement of a partner instead of sacrifice ratio gain ratio is considered.

Question 4.

Answer:
This statement is True.
When a person retires from the firm due to health issues, financial issues or personal reasons then it is known as person retires from the business and for the business, he is an outgoing partner.

Question 5.
On retirement of a partner, remaining partner will share the goodwill in their profit sharing ratio.
Answer:
This statement is False.
On retirement of a partner, after giving retiring, partner’s share in goodwill and if goodwill is written off, then remaining partners will adjust the goodwill in their new profit sharing ratio. (If raised to full extent and written off)

Question 6.
Retiring partner is not entitled to share in general reserve and accumulated profit.
Answer:
This statement is False.
General reserve and accumulated profit are created out of past undistributed profit, such profits are the outcome of hard work of all the partners including retiring partner. Hence, retiring partner’s has right to share general reserve and accumulated profit. He is therefore, entitled to get share in general reserve and accumlated profit.

2. Answer the following questions in around 35-40 words each.

Question 1.
Explain any one example of Flashbulb memory from your life.
Answer:

• I clearly remember the day when my grandmother passed away.
• On that day, I had an omelet for breakfast and went to college around 10.30 a.m. I attended only two lectures and then received a call about this bad news. After that, my best friend accompanied me home.

Question 2.
Explain the model of working memory proposed by Baddeley.
Answer:

• Baddeley called STM a working bench of memory.
• In the working memory model given by him, a central executive is responsible for the coordination between sub-systems of the phonological loop, episodic buffer, and the visuospatial sketchpad.
• Both phonological loop and visuospatial sketchpad have two components.

Question 3.
Explain the Tip of the tongue (TOT) phenomenon with an example.
Answer:

• Sometimes, when we search through our library of experiences to retrieve information from LTM, we cannot recall it even when we have that information on the tip of the tongue.
• e.g. you want to recall the name of your cousin’s favourite clothing brand. Instead of that name, you recall all similar names.

Question 4.
Give an example of episodic memory.
Answer:

• I remember a four-day-long celebration of my sister’s wedding.
• It started with Haldi followed by Mehendi and the sangeet ceremony. After that, there was a grand wedding followed by a reception ceremony.
• I also remember all preparations, outfits that I wore, and the food that we had in those four days.

Question 5.
What is motivated forgetting?
Answer:

• Motivated forgetting is a behaviour in which people may forget unwanted memories either consciously or unconsciously.
• It is also called a conscious coping strategy but it should not be confused with defense mechanisms.
• There are two levels of motivated forgetting, viz. Repression and Thought suppression.

3. Compare and contrast.

Question 1.
STM and LTM
Answer:

• Only the significant sensory inputs enter the Short-Term Memory (STM) through maintenance rehearsal. On the other hand, some items in STM enter the Long-Term Memory (LTM) after elaborative rehearsal which makes information meaningful and connects the same with already existing information in the LTM.
• STM holds the information between 15 to 30 seconds and the capacity of STM is about seven items at a time. Conversely, once information enters LTM, it is retained more or less permanently and the amount of information stored in LTM is unlimited.

Question 2.
Implicit Memory and Explicit Memory
Answer:

• Implicit memory is the unconscious memory of skills and how we do things while explicit memory is conscious memory of facts and events.
• Implicit memory is also known as procedural memory while explicit memory is also known as declarative memory.

Question 3.
Semantic memory and Episodic memory
Answer:

• Semantic memory is a more structured record of facts, meanings, concepts, and knowledge. On the other hand, episodic memory is a memory of experiences and specific events which we recall step by step to reconstruct the actual events.
• Semantic memories have personal context which includes vocabulary, mathematics, rules of logic while episodic memory is the memory of autobiographical events with times, places, and associated emotions.

Question 4.
Storage failure and Retrieval failure
Answer:

• In case of storage, failure acquired and encoded information is not stored properly while in case of retrieval failure, problems arise while recalling the stored information for its actual use.
• Both storage failure and retrieval failure make it difficult to use the retained information in the future.

Question 5.
Recall method and Recognition method
Answer:

• The recall method involves remembering a fact, event, or object that is not currently physically present and requires the direct uncovering of information from memory, (e.g. long essay-type answers). In the recognition method, already learned material is present and the learner has to recognize it. (e.g. MCQs).
• Recognition is relatively easier than recall. So, a score of memory by recognition method is usually more than the recall method.

4. What will you do if…

Question 1.
You have to prepare a long speech covering all the activities in your college and present at the annual function
Answer:

• I will make a list of all the activities and rehearse it a number of times so as to ensure better retention.
• I may also make a note with all points in brief which I can refer to if I forget something in the middle of a speech.

Question 2.
How will you apply ‘POWER’ to prepare for the final exam of Psychology?
Answer:

• Prepare: Before starting to study, I would prepare myself for it by setting goals. I will make myself aware of why am I studying Psychology, e.g. for acquiring good marks in the final exam.
• Organize: I will organize the study material properly and make a schedule for each chapter. I will allot less time for chapters that are easy and familiar. I may study these chapters when I am a bit tired. Conversely, I will allot more hours to chapters that are unfamiliar, complicated, or technical. I will also ensure to study these complex chapters when I am fresh.
• Work: I know that I have to work hard to achieve the goal of acquiring good marks. So, I will learn with the motive to understand and remember. I will try to associate new information with something that I have already learned.
• Evaluate: I will try to evaluate my progress by solving practice papers. It will enable me to know how much I have learned and the quality of my knowledge.
• Rethink: I will reanalyze, review, question, and challenge myself. I will also rethink whether I need to change my method of studying so as to achieve the goal of acquiring good marks in the final exam.

5. Short Notes.

Question 1.
Characteristics of Memory
Answer:

• Memory is an ability by which information is encoded, stored, and retrieved when needed.
• Three basic processes or characteristics of memory are Acquisition, Storage, and Retrieval.
• The acquisition is the process of acquiring information from our sense organs. The information acquired and encoded is stored over a period of time. In retrieval, the stored information is recalled for the purpose of its actual use.
• There are three stages of memory, viz. Sensory information store, short-term memory, and long-term memory.

Question 2.
Techniques to improve memory
Answer:
Some techniques to improve memory are as follows:

• Keyword method: In the keyword method, any two different pieces of information can be linked together. It is an effective method for remembering definitions and learning foreign language vocabulary.
• Encoding specificity: According to encoding specificity, memory is improved when information is available while learning is also available at the time to recall.
• Method of loci: It involves creating an imaginary route so that things can be remembered in a better way. e.g. steps to solve mathematical problems.
• Mnemonic devices: Mnemonics will include acronyms or first letter techniques (e.g. VIBGYOR includes colours of the rainbow). It will also include visualization. Another technique is chunking where one can place large information into small chunks.
• Practice and rehearsal: Relearning the same material a number of times lead to better retention and better recall. For small size or easy material, it is effective to optimally utilize our time and learn the entire material. For large size or difficult material, we must take breaks and learn the material in parts.
• Minimizing interference: We should not learn similar subjects together as they might interfere with each other. Also, one must take a rest for minimising such interference.
• POWER method: One can also use the POWER method for improving memory. Here, P stands for Preparation, 0 stands for Organisation, W stands for Work, E stands for Evaluation and R stands for Rethinking.

Question 3.
Motivated forgetting
Answer:

• Motivated forgetting is a behaviour in which people may forget unwanted memories either consciously or unconsciously.
• It is also called a conscious coping strategy but it should not be confused with defense mechanisms.
• There are two levels of motivated forgetting, viz. Repression and Thought suppression.
• Repression: Sigmund Freud’s Psychoanalytic model states that we subconsciously push unwanted thoughts and memories into our unconsciousness. People think that such repressed memories are completely forgotten.
• e.g. a girl who had experienced sexual abuse during childhood may completely forget about it. But she may have difficulty while forming a romantic relationship.
• Thought suppression: It is a conscious effort where we forget the memories of unwanted incidents and experiences of our lives, e.g. a person will avoid talking about his breakup.
• Thought suppression can be time-consuming and also quite difficult as such suppressed thoughts tend to reoccur, e.g. a person may try to suppress the thoughts about his ex but he may not be successful in doing so.

Question 4.
Causes of forgetting
Answer:

• Trace decay: Our memories fade out when we don’t use them for a longer period, i.e., traces of memory get decayed over time if they are not used.
• Trace distortion: Some researchers believe that memory traces are not decayed but are distorted over a period of time and forgetting occurs.
• Interference: Some researchers believe that we forget when materials that we learn one after the other interfere with each other. There are two types of interference, viz. retroactive interference and proactive interference.
• Motivated forgetting: It is a behaviour in which people may forget unwanted memories either consciously or unconsciously. There are two levels of motivated forgetting, viz. Repression and Thought suppression.

6. Answer the following questions in 150-200 words.

Question 1.
Explain the process of human memory in detail.
Answer:

• Memory is an ability by which information is encoded, stored, and retrieved when needed.
• The basic processes of memory include acquisition (encoding), storage, and retrieval.
  
• Acquisition/Encoding: Acquisition is the process of acquiring information from sense organs. Encoding is the process of transforming the information received into suitable symbols like pictures, figures, words, numbers.
• Storage: The information acquired and encoded is preserved over a period of time. The process of storage is essential for using that information in the future.
• Retrieval: It is the process of recalling the stored information for the purpose of its actual use. We tend to retrieve mobile numbers, names, etc. in our daily life.
• We can think of these processes as analogous to the functions of a computer.

Question 2.
Explain the theories of forgetting in detail.
Answer:

• Forgetting is the failure to retrieve the material from our long-term memory which we had already stored.
• Researchers have put forward various theories of forgetting. Each theory highlights different reasons behind forgetting.
• The various theories of forgetting are: Trace decay theory, Trace distortion theory, and Interference theory.
  • Trace decay: Our memories fade out when we don’t use them for a longer period, i.e., traces of memory get decayed over time if they are not used.
  • Trace distortion: Some researchers believe that memory traces are not decayed but are distorted over a period of time and forgetting occurs.
  • Interference: Some researchers believe that we forget when materials that we learn one after the other interfere with each other. There are two types of interference, viz. retroactive interference and proactive interference.

7. Arrange the following elements in concepts of memory in ascending order.

Question 1.
Elaborative rehearsal, Short Term Memory, Receiving information from the environment, Long Term Memory, Retrieval
Answer:

• Receiving information from the environment
• Short Term Memory
• Elaborative rehearsal
• Long Term Memory
• Retrieval

Activities

Activity 1 (Textbook Page No. 87)

Do you remember your first picnic at your school? Do you remember your primary school teacher? Now can you remember what food you ate last Monday? Why you can remember some incidents from the past clearly while you cannot remember some things which happened yesterday?
Answer:
We remember some incidents from the past clearly when they are a part of our long-term memory. Similarly, we cannot remember certain incidents from the recent past whey they form a part of our sensory or short-term memory.

Activity 2 (Textbook Page No. 87)

Why does this happen? 25 workers used to work in Thomas Edison’s Bulb and Phonogram unit of industries. There was a huge tree near his company. After 6 months, Edison asked his workers about the huge tree but not a single worker could give information about that tree. Why do you think this happened despite seeing the tree every day?
Answer:
I feel the none of the workers could give information about the tree near their company since it was a part of their sensory memory, i.e., they perceived the stimulus (tree) with sense organs but did not rehearse it enough for it to become a part of their long term memory.

3. Answer the following questions in 35 to 40 words.

Question 1.
Explain the functions of the hypothalamus.
Answer:

• Hypothalamus controls major bodily needs i.e., primary needs of an individual like hunger, thirst, sex as well as temperature regulation, and sleep.
• It is also called the pleasure center of our body.

Question 2.
Describe the functions of each of the four lobes.
Answer:

• Frontal lobe: It controls motor actions, thinking, memory and reasoning. It has Broca’s area which helps in speech production.
• Parietal lobe: It helps in understanding information regarding skin-like touch, pressure, pain, and temperature.
• Occipital lobe: It is the visual processing center. It controls the sense of hearing, smell, and taste. It has Wernicke’s area which helps in language understanding.
• Temporal Lobe: Hearing, understanding language, memory for language take place because of the temporal lobe.

Question 3.
Explain the functions of the Amygdala and Hippocampus.
Answer:

• Amygdala: It stores emotional memories of experiences. We experience emotions, especially fear due to the amygdala.
• Hippocampus: It is the storage of long-term memories. If a person gets Alzheimer’s disease, his hippocampus is. mainly affected.

Question 4.
What is a synapse? How does a nerve impulse travel from one to another neuron?
Answer:

• A synapse is a gap between two neurons.
• The nerve impulse or neural message jumps across the synapse in order to reach the dendrite of another neuron.
• When the neural message is passing through, it excites or inhibits the neurotransmitter in it. This chemical reaction decides our reaction to various situations.

Question 5.
Which are the important parts of the hindbrain? Explain their functions.
Answer:
Important parts of the hindbrain and their functions are as follows:

• Cerebellum: It helps in maintaining body posture and body balance. It also helps in the coordination of the movements.
• Brain stem: Medulla oblongata controls the breathing rate, pulse rate, blood pressure, and digestion. Pons sends and receives information from the lower parts of the brain. It helps to transmit messages between the cerebellum and cortex.
• Reticular activation system: Its main function is to maintain wakefulness, concentration, and alertness.

Question 6.
How do endocrine glands affect our behaviour?
Answer:

• Endocrine glands secrete chemical substances called hormones.
• Hormones are like messengers that are responsible for certain behaviours or the absence of reactions.
• e.g. Thyroid gland secretes the thyroxin hormone. Its hypersecretion leads to Grave’s disease while hyposecretion results in cretinism or myxedema.

4. Write short notes.

Question 1.
Autonomic Nervous System
Answer:

• The autonomic nervous system controls the internal activities of the human body including heart rate, breathing, digestion, disposal of waste products, and toxins.
• It is divided into the sympathetic and parasympathetic nervous systems.
• The sympathetic nervous system prepares our body to face stressful and threatening situations. It prepares us for a ‘flight or fight reaction. The job of the system is just opposite to its name.
• The parasympathetic nervous system takes over when the situation becomes normal. It directs our body to store energy for emergencies.

Question 2.
Limbic System
Answer:
One of the important parts of the brain is the limbic system.

• Hippocampus, amygdala, thalamus, and hypothalamus are parts of the limbic system.
• Hippocampus is responsible for the storage of long-term memories.
• Amygdala stores emotional memories of our experiences.
• Thalamus is called a relay station of the brain. It receives all information from the body and sends it to various parts of the brain.
• Hypothalamus controls major bodily needs like hunger, thirst, sex as well as temperature regulation, and sleep.

Question 3.
Neurotransmitters
Answer:
Neurotransmitters are chemical messengers. The important neurotransmitters are:

• Acetylcholine: It is a chemical released by motor neurons of the nervous system to activate muscles.
• Dopamine: It is released by the brain. If the level of dopamine is normal, we experience happy, pleasant feelings. It also plays an important role in the motivational process.
• Norepinephrine: It increases the force of skeletal muscles, especially during fight or flight response.
• Serotonin: It plays a role mainly in cognition, reward, learning, and memory. It also controls wakefulness, sleep, hunger, thirst, and liking.
• Glutamate: It helps in learning, memory, and maintaining sugar levels.
• GABA (Gama Amino Butyric Acid): It is the chief inhibitory neurotransmitter i.e. its principal role is to reduce the excitability of neurons throughout the nervous system. If it is less, it leads to convulsions and we cannot control body movements.

Question 4.
Pituitary gland
Answer:

• The pituitary gland is one of the endocrine glands, i.e., glands that secrete chemical substances into the bloodstream.
• It is also called as master gland as it helps other glands to produce their secretions and secretes the majority of hormones.
• It consists of the anterior lobe and posterior lobe.
• Anterior lobe: It secretes somatotropin, growth hormone, and adrenocorticotropic hormone. It helps the growth of the body and aids the adrenal gland. The hormones secreted by this gland are also vital for the nourishment of foetus.
• Hypo or hypersecretion in the anterior lobe: Hyposecretion leads to dwarfism, wherein a person is very short (two-three feet tall). On the other hand, hypersecretion can lead to gigantism, wherein a person becomes very huge and is eight-nine feet tall. Hypersecretion can also result in acromegaly, wherein a person has the features of a chimpanzee.
• Posterior lobe: It secretes oxytocin (which creates a feeling of happiness), pituitrin (which helps smooth muscle functioning of the stomach), thyrotrophic follicle-stimulating luteinizing hormone (which helps in the nourishment of foetus), and endorphins (which help to create neurotransmitters).

5. Compare and contrast

Question 1.
Sympathetic nervous system and Parasympathetic nervous system
Answer:

• The sympathetic nervous system prepares our body to face stressful and threatening situations. It prepares us for a ‘flight or fight reaction. On the other hand, the parasympathetic nervous system takes over when the situation becomes normal,
• Example:
  • Situation: Suppose you are chased by a dog.
  • Sympathetic nervous system: Due to the functioning of this system, your heartbeat and palpitation increase. You also start to sweat.
  • Parasympathetic nervous system: When PNS takes over, your heart rate, palpitation, and sweating become normal. You regain a cool and composed state due to the functioning of this system.

Question 2.
Exocrine glands and Endocrine glands
Answer:

• Exocrine glands directly release their secretions into the organ or tissue while endocrine glands secrete chemical substances into the bloodstream.
• Exocrine glands have separate ducts for their secretion and so, they are also called duct glands, e.g. sweat glands and tear glands. On the other hand, endocrine glands are called ductless glands as they don’t have a separate duct. e.g. pituitary gland and thyroid gland.

6. Answer in 150-200 words.

Question 1.
Explain the functions of various parts of the human brain.
Answer:
The brain consists of three major parts, viz. hindbrain, midbrain, and forebrain. Its functions are as follows:
i. Hindbrain

• Cerebellum: It helps in maintaining body posture and balance as well as aids in the coordination of movements.
• Brain stem: Medulla oblongata controls the breathing rate, pulse rate, blood pressure, and digestion. Pons helps to transmit messages between the cerebellum and cortex.
• Reticular activation system: It is the ‘Alarm clock’ of the body. It maintains wakefulness, concentration, and alertness.

ii. Midbrain: It sends information to the upper part of the brain and controls eye movements.

iii. Forebrain

• Cerebrum: Cerebral cortex controls higher-order mental processes such as attention, perception, learning, memory. The surface of the cerebral cortex is divided into right and left hemispheres. Neurons from the right hemisphere control the left side of the body and vice versa. Left hemisphere controls language, spatial relation, and pattern recognition.
• Four lobes: Frontal lobe controls motor actions, thinking, memory and reasoning. The parietal lobe helps us in understanding information regarding skin. The occipital lobe controls our vision. The temporal lobe is responsible for hearing, understanding language, and memory for language.

Question 2.
Explain the significance of endocrine glands in human behaviour. State the functions of any five endocrine glands in detail.
Answer:

• Endocrine glands secrete vital chemical substances called hormones. There is a strong impact of hormones upon human behavior.
• Hormones are responsible for certain behaviours or the absence of reactions.
• Over (hyper) or under (hypo) secretion of hormones may lead to a variety of problems.
• e.g. Hypersecretion of insulin and glycogen hormones by the pancreas reduces blood sugar levels. It results in hyperglycemia, wherein a person lacks energy and motivation, may faint and go to coma. Conversely, in the case of hyposecretion, a person gets diabetes. He becomes quite hungry and feels very tired and restless. He also shows irritated behaviour and faces frequent and uncontrolled urination.

The functions of the five endocrine glands are as follows:

• Thyroid gland: It secretes thyroxin which maintains the rate of metabolism.
• Parathyroid gland: It secretes parathyroxin which maintains calcium as well as phosphate balance.
• Pancreas: It secretes insulin and glycogen that is responsible for maintaining blood sugar levels.
• Adrenal gland: Cortex secretes cortin or cortisone which maintains the level of water, sugar, and sodium. The medulla secretes adrenalin (which is associated with fear) and noradrenaline (which is associated with anger). Medulla plays important role in emotional excitement.
• Gonads (sex gland): Testes in males secrete androgen and testosterone. These hormones are responsible for secondary sex characteristics in males. Their voice becomes hoarse. They also get mustaches and beards. Ovaries in females secrete estrogen and progesterone. These hormones are responsible for secondary sex characteristics in females. As a result, feminine looks develop and menarche begins.

Answer:

• Everybody deals with stress in different ways.
• When stress is too less or when it exceeds the limit, it deteriorates performance.
• Optimum performance can be achieved only under moderate stress.
• This can be explained with the help of a diagram:
  

Question (iii).
Explain the internal and external stressors with examples.
Answer:

• Internal stressors: These are stressors within us and we have to deal with them ourselves, e.g. a paralyzed individual may not be able to do any work which can lead to stress.
• External stressors: These are stressors from the outside environment which result in frustration, e.g. forgetting the PIN while using an ATM machine.

Question (iv).
What are the effects of hypo stress?
Answer:
Hypo stress is an insufficient amount of stress which is caused when a person has nothing to do at all. Its effects are as follows:

• It leads to boredom.
• It causes feelings of restlessness.
• People become demotivated and unenthusiastic.

Question (v).
Why the approach-avoidance conflict is most difficult to resolve?
Answer:
Approach-Avoidance conflict is most difficult to resolve because:

• An individual is attracted and repelled by the same goal.
• There is only one goal that has both positive and negative values.
• An individual has no choice. He has to accept the consequences of his choice.

3. Compare and contrast with examples.

Question 1.
Eustress and Distress
Answer:

• Eustress means good or a positive form of stress having a beneficial effect on health, motivation, performance, and emotional well-being (Merriam Webster). Conversely, distress is a negative type of stress and is experienced when the normal routine of an individual is constantly altered and adjusted.
• e.g. After a lot of practice, Amit is ready for his football match. He will experience eustress. e.g. Ajay is fired from his job and is not able to find a job anywhere else. He will experience distress.

Question 2.
Hypo stress and Hyper stress
Answer:

• Hypo stress is an insufficient amount of stress and is caused when an individual has nothing to do at all while hyper stress is caused due to extremely pressurizing conditions.
• Hypo-stress makes an individual demotivated, unenthusiastic, and restless while in case of hyper stress, a person may panic and engage in exaggerated reactions leading to frustration and agitation.
• e.g. When one cannot use his full potential in a job, it results in hypo stress. e.g. When one is stuck in a traffic jam, has forgotten to carry important documents for the meeting, and is late to work, it results in hyper stress.

Question 3.
Emotion-focused coping and Problem-focused coping
Answer:

• In emotion-focused coping, an individual focuses on the emotions resulting from stress. On the other hand, in problem-focused coping, an individual focuses effort on the problem and accepts the reality as it is.
• e.g. Nilesh tries to avoid negative emotions by keeping his mind stable with meditation or stuff down negative emotions by fighting with others. This is emotion-focused coping, e.g. When a chef gets negative feedback about a dish he has made, he makes more efforts to improvise the dish. This is problem-focused coping.

Question 4.
Attack and Withdrawal
Answer:

• In an attack strategy, an individual directly attacks the conflict as a direct way to resolve it. On the other hand, in withdrawal strategy, an individual may indulge in beating retreat or withdraw from the goal when he cannot achieve it after putting in his best efforts.
• e.g. When an employee wants a promotion and gets negative feedback on his presentation, he tries to improvise his presentation, learns, and asks for help from his seniors to get promoted (attack), e.g. If the employee is not promoted due to flaws in his presentation, he may leave the job altogether (withdrawal).

Question 5.
Compromise and Withdrawal
Answer:

• In compromise strategy, a person readjusts the goal to the nearest possible goal when he cannot achieve the original goal due to lack of capacity. Alternatively, in withdrawal strategy, a person may indulge in beating retreat or withdraw from the goal when he cannot achieve it after putting in his best efforts.
• e.g. An individual who wanted to become an orthopedic surgeon but could not manage to get admission. So, he took up physiotherapy as a career (compromise), e.g. On not getting admission, the individual may give up the field of medicine and his dream of becoming a doctor and pursue something else (withdrawal).

Question 6.
Projection and Rationalization
Answer:

• Projection involves the individual attributing his own thoughts, feelings, and motives to another person while rationalization occurs when a person attempts to explain or create excuses for his failure. By doing so, the individual avoids accepting the true cause of his failure.
• e.g. when a student has not studied for the exam, he may say that the questions were out of the syllabus (projection), e.g. when a person cannot afford a car, he says that cars are not environment friendly (rationalization).

4(1). What are the possible consequences?

Question (a).
Mehul is sufficiently prepared for his exams but feels tremendously stressed.
Answer:

• It is possible that Mehul might panic and go blank while writing the paper.
• So, Mehul should be confident about what he has studied and hope that he does well in the exam.

Question (b).
Sujata has nothing to do as her husband is a multimillionaire, nor does she have any hobby.
Answer:

• Sujata is facing hypo-stress as she has nothing to do at all. It is possible that she feels very bored, demotivated, unenthusiastic, and restless.
• In order to feel good about herself, she should pursue something she likes and diverts her mind.

Question (c).
Kalpesh sets his goals similar to his top ranker brother, without considering his ability.
Answer:

• Kalpesh will feel very stressed if he does not have the level of intelligence or ability required to meet the goals. It would lead to anger and frustration.
• There is also a possibility that he would feel extremely demotivated and leave the goal permanently.

Question (d).
Mohsin resorts to blaming others every time he fails.
Answer:

• Compromise: If a person cannot achieve the goal, he may readjust the goal to the nearest possible goal.
• Withdrawal: When a person cannot achieve a goal after putting in their best efforts, he may withdraw from the goal altogether.

Question 4.
Defense mechanisms
Answer:

• Defense mechanisms are an indirect way to combat stress.
• They are unconscious strategies used to protect the ego from breaking due to unacceptable/harsh reality. It functions as a shock absorber.

6. Answer the following questions in 150-200 words each.

Question 1.
Give the definition of stress and explain different types of stress.
Answer:
According to Richard Lazarus, ‘stress is a feeling experienced when an individual feels that the demands exceed the personal and social resources an individual is able to mobilize’.
The types of stress are as follows:

• Hypo stress: It is an insufficient amount of stress and may be due to work under load. When people have nothing to do, they get bored and if this feeling persists for a longer time, it results in hypo-stress. People with hypo-stress are demotivated, unenthusiastic, and restless.
• Hyper stress: It is a result of extremely pressurizing conditions. Due to hyper stress, a person may experience panic attacks and may engage in exaggerated reactions like throwing temper tantrums. It leads to frustration and agitation.
• Eustress: It is a good form of stress which has a positive effect on health, motivation, performance, and emotional well-being. It is a state when an individual is excited, determined, inspired, energized, and ready to go. While experiencing eustress, the body is temporarily and intensely flooded with hormones like oxytocin and dopamine.
• Distress: It is a negative type of stress. An individual experiences it when the normal routine is constantly adjusted and altered. While experiencing distress, our body is flooded with emergency response hormones like adrenaline and cortisol. Distress is divided into two types:
  • Acute distress: It is intense, short-term negative stress.
  • Chronic distress: It is a long-lasting, recurrent negative stress.

Question 2.
What is meant by conflict of motives? Explain the different types of conflicts with examples. Illustrate your answer with appropriate figures.
Answer:
Conflict of motives refers to the clash between two or more equally strong and incompatible motives occurring at the same time that compels an individual to make a choice, which in turn leads to stress.
The types of conflict are:
i. Approach-Approach conflict: There is a conflict between two positive and attractive goals. The decision will depend on the attractiveness of the goal and its valence may change, e.g. Bhoomi wants to take up two courses but they are both scheduled at the same time.

ii. Avoidance-Avoidance conflict: The conflict involves two goals with negative values. An individual is forced to make a choice between two negative and unattractive goals, e.g. Ritu must work at a job which she dislikes, or else she must remain unemployed.

iii. Approach-Avoidance conflict: There is only one goal and it has positive as well as a negative value. This type of conflict is very difficult to resolve. There are three possible reactions in such a situation: give importance to a positive value, be cautious about the negative value and leave the goal altogether, e.g. Aryan receives a letter of acceptance from a college of his choice but it is very expensive.

iv. Double Approach-Avoidance conflict: An individual faces conflict between two or more goals that have an equal positive or negative value. However, an individual is always disappointed with the choice he makes as he has to lose the other goal, e.g. Richa has to choose between two boys for marriage. One is handsome but boring.

My uncle loves to eat sweets but he is a diabetic and so, he is always thinking about how to resolve this conflict. My younger brother has to choose between doing homework and going to tuition. He dislikes both.

All these types of conflicts are difficult to resolve but solving them is also very important. Everybody deals with the resulting stress in different ways. Ideally, we should weigh the pros and cons of every situation and then come to a conclusion.

3. Compare and contrast.

Question (i).
Realistic perception of self and Unrealistic perception of self
Answer:

• Realistic perception of self means being aware of our own strengths and weaknesses. It also means using strengths for the betterment and modifying the weaknesses. Realistic people do not get upset when they are confronted with failure. All of this enables them to deal with life more effectively.
• Unrealistic perception of self makes an individual expect things that are not feasible. They are likely to face dejection, frustration, and sadness. They may not be able to recognize their own strengths and may feel incompetent. They even blame others for their shortcomings.

Question (ii).
Openness to new experiences and Inhibitions/Fear of new experiences
Answer:

• People who can comfortably deal with strangers and are confident in voicing honest opinions are open to new experiences. They are eager to take on life, try out new trends, go to new places and reach out to people from different backgrounds, communities, and locations. They are confident and dare to take risks regarding unknown experiences,
• People who are fearful and hesitant are not open to changes, new places, new people, and experiences. These individuals find it hard to deal with changes and get anxious while interacting with strangers.

Question (iii).
High self-esteem and low self-esteem
Answer:

• People having high esteem like themselves and radiate confidence and assertiveness. They are happy with themselves and are liked by all because of it. It also results in better relationships. Well-adjusted individuals have high self-esteem.
• People with low self-esteem don’t think that they are loved, valued, or considered worthy. They don’t have a positive image of themselves. This leads to anxiety and poor performance. Consequently, they indulge in self-blame and continue to feel incompetent.

Question (iv).
Sympathy and Empathy
Answer:

• Sympathy is feeling sorry and having pity for the hardship or losses that another person faces. In this case, an individual genuinely feels bad for the hardships or grief faced by others.
• Empathy is putting yourself into someone else’s shoes. It refers to understanding the situation from that person’s point of view and actually feeling his pain. Hence, empathy is a more intense level of emotion than sympathy.

For your understanding

	Empathy	Sympathy
Meaning	Understanding what others are feeling because you have either experienced it yourself or can put yourself in their shoes.	Acknowledging another person’s emotional problems and trying to comfort or console them.
Example	Situation: Tushar fails in his preliminary exam and is upset.
	Empathetic response by Tushar’s friend: “I have been through this situation in the past so I know how it feels. But don’t worry. You can do better in final exam.”	Sympathetic response by Tushar’s friend: “I understand your situation. But failure is a part of life. So instead of being upset, let’s focus on how you can do better in final exam.”

Question (v).
Behavioural perspective and Humanistic perspective to abnormality
Answer:

• Behavioural perspective looks at the observable behaviour of an individual. This perspective believes that ineffective learning and conditioning can lead to abnormal behaviour. Behavioural psychologists treat such abnormalities with the help of the principles of reinforcement and punishment.
• Humanistic perspective looks at the ways human beings are driven to grow, change and develop into the best versions of themselves. This perspective believes that abnormalities get formed when personal growth is blocked. Humanistic psychologists treat such abnormalities by creating conditions that allow positive and healthy growth of the individual.

Geeta is more interested in literature but being the only daughter of a well-established orthopaedic surgeon having his own hospital, she is under pressure of choosing medical profession as her career.
Answer:

• It is possible that Geeta follows her father’s footsteps and becomes a doctor. But she will not be self-motivated and may resent her work. She is likely to get frustrated when encountered with setbacks.
• It is also possible that she (firmly but gently) tells father of her interest in literature and convinces him that literature is where her heart and passion lies. In this case, she will not blame anyone during rough times and will be motivated to resolve the difficulties that may arise.

Question (b).
Sujata is an intelligent girl but she is extremely sensitive to criticism and perceives herself as less competent.
Answer:

• Sujata will keep getting disheartened when criticised. There are chances that this may happen frequently since she has no control over other’s behaviour.

Trisha is not able to make friends. She cannot initiate conversation with strangers at all. She is placed as a leader of one of the teams for campus-cleaning.
Answer:

• Her team mates may make fun of her and won’t look up to her as a leader. She may end up taking the cleaning activity all by herself and the team will not listen to her at all.
• However, if she views it as a challenge and responds positively to the situation, she might be able to overcome her weaknesses.

6. Case study

Read the following case carefully and answer the questions based upon that.

Pritha was a merit holder girl from a middle class family. She joined a college where majority of students were from a rich background. Although she was capable of following lectures and was doing well in her studies, she felt lonely as she could not get acceptance in the groups of her classmates coming from affluent families. She tried to dress like them, and started asking for extra pocket money from her parents. Her classmates joked at her dressing sense. She could not tolerate the mockery and stopped going to the college.

Instead, she started spending time visiting strange places like public parks, railway stations and shopping malls. She did not appear for any of her exams. Her parents were unaware of all these things and on asking about college or studies, Pritha answered them without revealing the truth. It the end of the year, her parents received her report card by post from her college with a remark that ‘Your ward has to take College Leaving certificate.

On confronting Pritha, she became violent and started damaging the furniture uttering bad words about the middle class people and there after her utterance was incomprehensible for her parents. This continued for a very long time.

Question 1.
Which problems did Pritha face in her college?
Answer:
Pritha got isolated with her peers because of her economic background. She also faced bullying as her affluent classmates made fun of her dressing sense. She felt humiliated and unaccepted. It affected her mental well-being. She probably felt that she could not discuss those issues at her home and felt helpless.

Question 2.
Could Pritha, according to you, have avoided her condition of feeling lonely?
Answer:
It was a very difficult and disturbing phase in her life. But she could have talked to her teachers and parents and sought their guidance. She could have also shared everything with her friends outside college.

Question 3.
What would you do if you were in Pritha’s place?
Answer:
I would have talked to my parents and discussed everything openly. My parents would have surely guided me on how to deal with peers coming from different backgrounds and provided me their thoughts and ideas. I would also have concentrated more on my studies.

Question 4.
Do you think Pritha should have spoken to her parents about her feelings at college? If yes, how it would have helped her?
Answer:
Yes, Pritha should have spoken and informed her parents of what was going on in her college life, instead of lying about going to college. Lying was only multiplying her troubles. They could have given her support and also maybe talked to her teachers and managed to get the situation under control.

7. Answer the following questions in 150-200 words.

Question 1.
What are the criteria of abnormal behaviour? Explain with examples.
Answer:
All of the following criteria need to be considered together in order to determine if a person displays abnormal behaviour.

Personal distress: Personal distress refers to subjective feeling of an individual in response to persons and events creating extreme discomfort. It includes feeling very low, depressed, facing problems like social withdrawal, e.g. A person feeling down and sad every day is considered abnormal.

Deviance: Behaviour against the set laws of the state or behaviours different than standard social and statistical patterns exhibited by most of the people, e.g. Deliberately engaging in behaviour which is harmful to self and others.

Failure to perform functions normally: Day-to-day functioning getting impaired, i.e. inability to fulfil appropriate and expected roles in family, social and work related situations, e.g. A person is not able to perform his daily chores and fulfil work commitments due to lethargy.

Question 2.
What are the causes of abnormal behaviour?
Answer:
There are primarily seven psychological perspectives of abnormal behaviour. All these perspectives indicate different factors as the causes of abnormal behaviour. Additionally, Stress Diathesis Model and Biopsychosocial Model also discuss the causes of abnormal behaviour.
The causes of abnormal behaviour can be explained as follows:

• Biological perspective: Abnormal behaviour results due to chemical imbalance or physiological factors.
• Sociocultural perspective: Abnormal behaviour is learnt within the social context.
• Behavioural perspective: Abnormal behaviour is learnt due to ineffective learning and conditioning.
• Evolutionary perspective: Abnormal behaviour is an exaggerated form of adaptive action.
• Humanistic perspective: Abnormal behaviour arises from blocked personal growth.
• Psychoanalytic/Psychodynamic perspective: Abnormal behaviour is due to unconscious and unresolved conflicts.
• Cognitive perspective: Abnormal behaviour arises due to false assumptions and faulty thinking.
• Stress-Diathesis model: Disorder = Nature (Biological and genetic factors) + Nurture (Life experiences)
• Biopsychosocial model: Abnormal behaviour = Biological factors + Psychological factors + Sociocultural factors

Question 3.
Describe the challenges faced by adolescents with examples.
Answer:
Adolescence is the transitional period associated with a number of physiological and psychological changes. It is called the period of ‘storm and stress’. Since adolescents are neither children nor adult, they face many challenges as follows:

• Sexual orientation issues: Adolescents who are homosexual or bisexual become confused when they realise that their sexual orientation is different from peers.
• Gender identity issues: Some adolescents may show traits typically thought to be of the other gender. If they are not allowed to behave in a way that is natural to them, they become rebellious.
• Bullying issues: Adolescents may face the problem of being bullied. They may be humiliated or fall victim to other people’s aggression when they have less power or prestige.
• Other challenges:
  • Self-identity issues since they are neither adult nor children.
  • May feel inferior, shy and have difficulty in mixing with peers.
  • Lack of self-confidence may perceive others negatively.
  • May become conscious about their physical features.
  • May become moody and unpredictable due to hormonal changes.
  • May feel excessive pressure due to expectations of oneself and parents.

Activities

[Note: The answers of activities will be very subjective. The answers provided are for reference. Students are expected to perform these activities on their own.]

Activity 8 (Textbook Page No. 50)

Think about the following situations. Try and apply the criteria for abnormality that you came up with, to these cases and try to judge if they could be called abnormal.

1. Sameer likes to dress up like girls.
2. Kushal is confused about his sexual orientation.
3. After marriage, Shoaib went to live with his in-laws.
4. Joseph loves to be alone and travels alone.
5. Delnaz is introvert and does not like to mix with any one.

Answer:

1. Sameer may be having gender identification issues and must be feeling more feminine than masculine. But I think it is not abnormal.
2. Kushal may not be aware that there can be heterosexuals, homosexuals and bisexuals and it is perfectly normal to be any of them.
3. Although usually it is the bride who lives with in-laws after marriage, I don’t think of Shoaib’s behaviour as abnormal. It is just different than a normal social pattern.
4. If Joseph wants to be alone and travel alone at times, it seems to be alright. Maybe he’s going through a phase of self discovery. However, if this pattern continues for a longer duration and hampers his social relationhips, then it is abnormal as human beings are social beings.
5. Delnaz can be considered abnormal if she doesn’t like interacting with anyone, including her near ones and family. However, being introvert does not mean someone is abnormal.

Activity 11 (Textbook Page No. 54)

You are all adolescents now. Think about how you are today and how you were in 5th/6th standard. Make two columns and note down the changes you see in these five domains: your self-image, your confidence, relationships with your parents, physical changes, and importance of friends in your life.
Answer:

Self-image	Has become more positive
Confidence	Improved significantly as I know what I am capable of
Relation with parents	Continues to be warm and close
Physical changes	Increase in height, weight and chainge in overall appearance
Importance of friends	Increased importance as we understand each other better

i. Development follows a specific pattern:
Like other species, human beings follow a specific pattern and sequence of development in the prenatal and postnatal periods. They may skip a particular stage, but the order or pattern will remain the same. The specific pattern is observed in behavioral development as well. Sexual development also starts at a specific age.

ii. Development takes place in a specific direction: Development takes place during the prenatal and postnatal stages based on the two principles of development, viz. Cephalocaudal principle (development proceeds from the head to toe) and Proximodistal principle (development proceeds from the center of the body to outward).

iii. Development is continuous: There are various stages of the human life span like prenatal, infancy, early childhood, late childhood and adolescence, early youth, adulthood, and old age. One stage of development lays the foundation for the next stage. The rate of development varies across stages.

iv. Development proceeds from general to specific: The infant’s first motor movements are very generalized; like reflexes and non-directional waving arms or kicking before being able to reach or crawl towards an object. The child uses his full hand before developing finger dexterity.

v. There are individual differences in development: Although the pattern and sequence for growth and development are usually the same for all, the rate at which every individual reaches that stage is different. Some individuals attain a particular stage very early while others mature late.

vi. The rate of development is different for different body parts: The child first develops control over his neck then raises his head resting on his chest, then sits, crawls, and finally starts walking.

vii. Development leads to integration: A child starts producing sounds first, then monosyllable, then words, then sentences, and then complex sentences. This is how development leads to integration. In this process, physical and mental growth does not occur simultaneously.

viii. Behavioural problems are normal for a particular stage: There are certain behavioural patterns observed in every stage. Any variation in that pattern need not necessarily be labelled as abnormal. This is because some behavioural patterns perceived as problems by parents may subside with age.

ix. Development is predictable: The rate of development is fairly constant for every child. So, it is possible to predict a child’s development.

x. The child develops as a unified whole: Physical and mental development, as well as socio-cultural factors, influence each other and in turn, affect the development of an individual as a whole.

Question 2.
Why is the prenatal period the most crucial period in development?
Answer:
A period between conception till birth is called a prenatal period. It is the most crucial period in development due to the following factors:

• Heredity serves as the foundation for later development.
• Favourable conditions in the mother’s womb can foster the development of hereditary potentials while unfavourable conditions can block their development.
• Sex determination takes place during the first three months of life.
• Proportionally faster growth and development take place during the prenatal period as compared to an individual’s entire life.
• Failure to take proper care of the mother may lead to physical and psychological hazards to the unborn child.

Question 3.
What are the developmental tasks?
Answer:
There is a set of expectations about changes in an individual at a certain age based upon the norms of development. This set is known as a developmental task. The developmental tasks at different stages are as follows:

• Prenatal stage: In this stage, the child is completely dependent on the mother for nourishment. There is the rapid development of physical systems and organs.
• Neonatal stage: The child is still dependent on the mother and there is the development of initial reflexes.
• Infancy: This stage is associated with motor, cognitive and psychosocial development as well as rapid physical development.
• Early childhood: Although physical development is comparatively slow, we observe increased cognitive and linguistic development. It is also associated with the beginning of socialization.
• Late childhood: School provides an opportunity for overall development during this stage. There is the development of physical, mental, cognitive, and psychosocial abilities.
• Adolescence: Rapid visible physical changes occur in this stage. Also, the concept of self-identity and career-related awareness begins to develop.
• Early adulthood: Individual completes education and chooses his career. He also chooses a suitable partner and gives importance to family responsibilities.
• Late adulthood: There are more family and occupational responsibilities. Adults in this stage take responsibility of their parents. Also, women go through menopause and men experience andropause.
• Old age: Retirement life begins in this stage. Leisure is forced on people due to old age. People also experience many health problems. Also, they start thinking about death.

Question 4.
Describe the neonatal stage.
Answer:
The neonatal stage is the period from birth to two weeks.

• During this period, a newborn starts adjusting to the external environment, e.g. outside temperature.
• The neonate sleeps for around 18 to 20 hours.
• The characteristics of the neonatal stage are as follows:
  • It is the shortest of all developmental periods.
  • It is the time of radical adjustment.
  • It can be a hazardous period, both physically (because the neonate has to make radical adjustments to the new and different environment) and psychologically (because it is the time when the attitudes of significant people in neonate’s life will have an effect on his development).

Question 5.
What are the characteristics of early childhood?
Answer:
The early childhood stage extends from two years to about six years. The characteristics of early childhood are as follows:

• Parents call this age ‘toy age’ as children play with toys.
• Educators call this age ‘preschool age’ as the child starts going to preschool.
• Psychologists term this age as ‘pre-gang age’ as in the previous stage the child plays alone and does not share his toys but now he starts mixing around.
• Children in this stage experience stranger anxiety or separation anxiety.

Question 6.
Write the characteristics of late childhood.
Answer:
The late childhood stage ranges from six years to 11 years of age. The characteristics of late childhood are as follows:

• Children in this stage are curious by nature and experiment with new ideas. They are not satisfied with lame answers. For many parents, late childhood is a troublesome age.
• Educators regard late childhood as a critical period in the achievement drive. According to educationalists, this is the age of skill development.
• For psychologists, late childhood is the gang age. During this stage, boys and girls make their separate gangs.

Question 7.
Describe the problems during adolescence.
Answer:

• Internet addiction: Adolescents indulge more in social media (WhatsApp, Facebook) and online games. Their addiction to the internet due to these applications results in problems like lack of concentration and social interaction.
• College dropouts: Some adolescents may leave college before completing their graduation due to financial or academic problems.
• Identity crisis: Adolescents are confused about ‘who they are because they are neither children nor adults. Parents treat them differently in different situations. Some adolescents pursue a psychological moratorium, i.e. a period in which they take time off from the upcoming responsibility of adulthood to explore various roles and possibilities.
• Depression: When adolescents experience a breakup in a relationship, failure in exams, or death of a loved one, they experience feelings of sadness, loss, or grief. Sometimes, they feel so hopeless that they stop following normal routines. Depression could be due to genetic and environmental factors.
• Suicide: Although girls attempt suicide more frequently than boys, the rate of adolescent suicide is higher for boys. This is because boys use violent means to commit suicide. Social inhibition, perfectionism, and a high level of stress/anxiety create a higher risk of suicidal attempts.

Question 8.
Write a note on adulthood.
Answer:

• Adulthood ranges from 21 years to 40 years.
• The prime concerns for a young adult are personal career choice and economic independence.
• At this stage, an individual tries to settle in his life. Men and women take responsibility for their families and start earning money.
• The characteristics of Adulthood are as follows:
  • Adulthood is the age of settling down. Once they are legally mature, adults have to shoulder their own responsibility.
  • Adulthood is the reproductive age.
  • Problems faced in this stage are different from those faced at earlier stages.
  • An adult tries to establish himself in life and so, experiences tension.
  • As adults start working and get married, they don’t get time to mingle around with their friends like earlier.
  • They have to adjust to new patterns of life.
  • Adulthood is a time of changing experiences and changes in the value system.
  • Early adulthood is the time of adjustment to the new lifestyle.

Question 9.
Explain the adjustment problems in middle age.
Answer:
The middle age or late adulthood period ranges between 40 years to 60 years. The adjustment problems in this stage are as follows:

• It is a time of transition where both men and women leave their physical and behavioural characteristics of adulthood.
• It is a dreaded period due to mental and physical deterioration. The capacity of reproduction, as well as mental and physical capacities, slowly begins to decline.
• It is the time of more responsibilities. They assist the next generation to be competent.
• It is a time of stress as there is a radical financial burden.
• People in this stage may experience nervous breakdown and anxiety.
• It is the time of ‘Empty Nest’ as children go out for higher education, job or get married.

Question 10.
Discuss the application of the principles of human development in different fields.
Answer:

• There are two principles of development, viz. Cephalocaudal principle (development proceeds from the head to toe) and Proximodistal principle (development proceeds from the center of the body to outward).
• These principles prove helpful to doctors while evaluating the development of an individual. Further, the application of the cephalocaudal principle can also be seen in corporate organizations where decisions taken by the board of directors at the top level are communicated to and implemented by managers and workers. Similarly, the proximodistal principle applies to the development of cities from the center to the outward peripheries.

3. Compare and contrast.

Question 1.
Growth and development
Answer:

• Growth is quantitative change and it refers to physical changes. On the other hand, development is qualitative change and it includes physical as well as mental changes.
• Growth is perceived through changes in size, weight as age advances and it is a part of development. Development is perceived through changes in behaviour and it is all-inclusive in nature.

Question 2.
Maturation and development
Answer:

• Maturation refers to a natural unfolding of the genetic potential at the appropriate time in the course of development. Maturation denotes changes in specific behavioural patterns while development denotes qualitative changes.
• Maturation changes are genetic and cannot be speeded up. On the other hand, development results from an interaction between maturation and exposure to training as well as environmental factors.

Question 3.
Prenatal and post-natal stages of development
Answer:

• A period between conception till birth is called the prenatal period while the period after birth till death is called a post-natal period.
• The stages in the prenatal period are the germinal stage, embryonic stage, and fetal stage while the post-natal period consists of a neonatal stage, early childhood, late childhood, adolescence, early adulthood, late adulthood, and old age.

4. How will you deal with the following situations if it were you in those situations?

Question (a).
Grishma thinks she is extremely good-looking – which is not true in reality – she aspires to become a star model.
Answer:
I feel few important characteristics to become a star model are confidence, physical fitness, gracefulness, and determination.

I will talk to Grishma about the incongruence between her ‘real self’ (self-image) and ‘ideal self. I will also make her understand that even though she is not extremely good-looking, she can actualize her potential by taking efforts to sharpen her other positive attributes.

Question (b).
Harshad is avoiding places where he has to meet many people as he wears spectacles and he has got lot of pimples.
Answer:

• I will make Harshad realize that his pimples or spectacles do not define ‘who he is’ or, determine his worth as a person. So, he should not let it impact him in a negative manner.
• I will also highlight his strengths to make him understand that his ‘self-concept’ should be based on a broader range of aspects than just a body image. I will also encourage him to engage in diverse social interactions to improve his sense of self-worth.

Question (c).
Sushma is too short so she does not mix with others.

5. Write short notes in 50-60 words each.

Question 1.
Gender role
Answer:

• It is determined by the family atmosphere as well as cultural influences where the child learns through observation and imitation.
• e.g. if a girl is assertive and practical, she may be considered to be ‘masculine. This is because these attributes are usually associated with boys.
• However, gender-based roles are diluting in modern times. Society is approving and accepting these changes with an open mind.
• e.g. Pt. Birjoo Maharaj, Sanjeev Kapoor, Vikram Gaikwad are famous in female-dominated areas while Phogat sisters, Kalpana Chawla, Kiran Bedi are successful in male-dominated areas.

For your understanding

• Due to societal expectations, both males and females are expected to behave in certain ways, e.g. men are taught that they should be strong. If they cry, it is considered to be ‘girl’.
• However, now people have begun to realize that there is nothing wrong if a man takes up a feminine role or a woman behaves in a masculine way.

Question 2.
Carl Rogers’ theory of self
Answer:

• According to Carl Rogers, every individual has a tendency to actualize himself.
• Two important concepts related to Roger’s theory are the real self and the ideal self.
• The real self is what we actually are while the ideal self is what we want to be. The real self has a tendency to actualize himself. But the ideal self may consist of some goals which are beyond our reach.
• High congruence between the real self and ideal self leads to healthy productive life while a large gap or incongruence between them leads to maladjustment.
• By trying to achieve our full potential, we strive to be fully functioning individuals, i.e. achieve self-actualization.
• People who achieve self-actualization are well-balanced, well-adjusted, and interesting.

Question 3.
Self-efficacy
Answer:

• Self-efficacy is a person’s belief in his ability to accomplish some specific goal or a task.
• It depends on his trust in his own competency. Competence can vary between different situations, e.g. a person’s self-efficacy may be high in painting but low in cooking.
• Self-efficacy is based on ‘Social cognitive theory. The theory holds that humans actively shape their lives rather than passively reacting to the environment.
• Maddux defined self-efficacy as ‘what I believe I can do with my skills under certain conditions.
• Two factors related to efficacy are outcome expectancies (skills required to complete the goal) and efficacy expectancies (person’s analysis about whether he has those capacities).
• Self-efficacy can be improved by reinforcing oneself, developing one’s own skillset, choosing a role model for a particular activity and following him, seeking constructive feedback from others, and learning techniques to control one’s own emotional arousal.

Question 4.
Self-awareness
Answer:

• Self-awareness is the quality or trait that involves conscious awareness of one’s thoughts, feelings, behaviours, and traits.
• In order to have a proper self-concept, one must have some level of self-awareness, i.e. understanding that a person has a separate identity from others.
• According to Piaget, self-consciousness starts emerging between 15-24 months.
• Self-awareness is necessary before the child becomes aware of being a focus of attention. It enables him to understand what others are feeling. It also enables him to identify what belongs to him and what belongs to others.

Question 5.
Self-esteem
Answer:

• According to Seligman, ‘self-esteem is your overall evaluation of your worth as a person, high or low, based on all positive and negative self-perceptions. It is the respect one has for himself.
• A person may have various levels of self-esteem, e.g. a girl may have high self-esteem about her intelligence but may have low self-esteem about her looks.
• People with high self-esteem are positive, responsible, genuine, and committed to their goals. They have strong internal values and forgiving nature. They continuously seek to improve themselves.
• On the other hand, people with low self-esteem are negative, need externally oriented goals, and are impatient with themselves as well as others. They are unhappy and experience anxiety. They may also have a superiority or inferiority complex.
• Some of the ways to improve one’s self-esteem are as follows:
  • Eliminate negative self-talk
  • Recognize your strengths
  • Recognise self-worth
  • Accept mistakes
  • Accept rejection

Question 6.
Self-regulation
Answer:

• Self-regulation is being able to control our own thoughts, feelings, and actions for our own benefit.
• It involves monitoring one’s own actions and reactions. When one engages in self-regulation, he avoids impulsive reactions.
• It also involves predicting the consequences of our behaviour and avoiding behavioural patterns which can negatively affect ourselves or others in the future.
• Self-regulation also involves focusing on certain parts of life and ignoring some other parts for the time being, e.g. as exams approach, a person will stop spending time on Netflix and focus on studies.
• Higgins’ research on regulatory focus showed that people either have promotion regulatory focus or prevention regulatory focus.
• It means people either focus on achieving positive outcomes or don’t do anything in order to prevent negative outcomes.
• Self-regulation has crucial implications in our life.

6. Answer the following questions in 150-200 words.

Question 1.
Give a detailed account of the development of an individual’s self-concept through the stages of life.
Answer:

• On average, till the age of six months, the child is unaware of himself. As the child grows, he starts making distinctions between his own body and everything else.
• In normal children, face recognition with a mirror occurs at the average age of one and half years. They are capable of pretend play. They also start using personal pronouns, (I, me, mine).
• By the age of two, the child becomes aware of general expectations (what is good/ bad behaviour). They smile when people smile at them and frown when others get angry. They also develop a sense of self by comparing themselves with the standard role model (beginning of self-esteem).
• By the age of three, children start recognizing themselves and others as boys or girls.
• Between the age of three to twelve, the self-concept is defined mainly in terms of sex, age, family, and what the child believes he or she can or can’t do.
• When schooling starts at the age of five-six, a child begins to compare himself to others (beginning of social comparison). Also, the development of the private self-concept takes place during this stage.
• The final unfolding of self-concept during adolescence involves perspective taking, i.e. thinking and understanding other’s point of view. They might even enter into the stage of objective self-awareness.

Question 2.
Explain the theory of the self as proposed by Carl Rogers.
Answer:

• According to Carl Rogers, every individual has a tendency to actualize himself.
• Rogers also asserted that mentally healthy individuals have congruence between their experience and their self-concept while neurotic individuals deny awareness of their sensory and emotional experience.
• Two important concepts related to Roger’s theory are the real self and the ideal self.
• The real self (self-image) is what we actually are while the ideal self is what we want to be. The real self is our inner personality while the ideal self represents our dynamic ambitions and goals.
• The real self has a tendency to actualize himself. But the ideal self may consist of some goals which are beyond our reach. This may result in the gap between the real self and the ideal self.
• High congruence between the real self and ideal self leads to a greater sense of self-worth and healthy productive life while a large gap or incongruence between them leads to maladjustment.
• By trying to achieve our full potential, we strive to be fully functioning individuals, i.e., achieve self-actualization.
• Self-actualization means recognizing and exploring one’s full potential. People who achieve self-actualization are well-balanced, well-adjusted, and interesting.

Congruent

The self-image is similar to the ideal self.
There is more overlap.
This person can self-actualize.

Incongruent

The self-image is different from the ideal self.
There is only a little overlap.
Here self-actualization will be difficult.

Answer:
1. Greek word: Psyche – Soul
2. John Locke – Empty slate
3. First Psychological Laboratory
4. Sigmund Freud – Founder of Psychoanalysis
5. John Watson OR Organism’s response to stimuli – Behaviour

2. Explain the following concepts.

Question 1.
Psychology
Answer:
The word Psychology is derived from Greek words – ‘Psyche’ and ‘Logos’. It is denoted by the Greek Alphabet “Psi” and the symbol is 4L Wilhelm Wundt defined it as “the study of consciousness”. Dr. Sigmund Freud defined it as “the study of unconsciousness”. John B. Watson defined it as “the science of human behaviour”. The latest definition of Psychology is ‘The study of human behaviour and mental processes.

For your understanding

• Conscious mind: It is the level of mind that someone is aware of at any particular point in time.
• Unconscious mind: It contains thoughts, memories, and desires that are buried deep in us. Although we are not aware of their existence, they exert great influence on our behaviour.

Question 2.
Behaviour
Answer:
In general, behaviour is an organism’s response to various internal and external stimuli.
John Watson defined behaviour as ‘anything that can be observed, recorded and studied in human beings and animals.’ Behaviour is either overt (seen) or covert (hidden).

Question 3.
Overt behaviour
Answer:
Overt behaviour is that behaviour that is directly noticeable or observable. It includes responses such as walking, talking, dancing.

Question 4.
Covert behaviour
Answer:
Covert behaviour is that which is not directly noticeable but can be inferred from behaviour like thinking, feeling. It basically includes mental processes.

Question 5.
Stimulus
Answer:
Stimulus is defined as any physical event or condition that gives rise to a reaction. It can be external or internal.
In simple words, it is an object or event that elicits a sensory or behavioural response in an organism.

Question 6.
Response
Answer:
A response is defined as a reaction of the organism to a given stimulus. All organisms respond differently to the same stimulus.
Example:
Stimulus (S): A teacher asks students to prepare a presentation.
Organism (O): All students present in class.
Response (R):

• Some students actively participate in presentations.
• Some students remain silent as they are scared to talk in front of the entire class.

3. Answer the following questions in 35-40 words.

Question 1.
Psychology is a science: explain why?
Answer:

• Psychology is the scientific study of human behaviour and mental processes.
• Through experiments and observations, Psychologists try to analyze and predict human behaviour. This shows the empirical nature of Psychology.
• Wilhelm Wundt used scientific methods to study fundamental psychological processes. John Watson also conducted scientific research on animal behaviour and child-rearing.

Ques 2.
Explain the S-O-R model, with your own experience.
Answer:

• The S-O-R model explains how organisms respond differently to the same stimulus. It can be explained as follows:
  
• Example: Suppose Neha is an excellent orator while her friend Seema is afraid of public speaking.
  • Stimulus: The teacher asks Neha and Seema to give speeches.
  • Organism: Neha and Seema.
  • Response: Neha will confidently give her speech.
    Seema is likely to get cold feet and become nervous.
• This shows that different organisms (Neha and Seema) react differently to the same situation.

Question 3.
Explain the goals of Psychology.
Answer:

1. Describe
   • To precisely identify and classify behaviours and mental processes
   • Involves recording behaviour using various tools
2. Explain
   • To understand the causes of behaviour through meaningful explanation of facts
   • Involves the use of standardized tests
   • Behaviour observed in most people can be generalized
3. iii. Predict
   • To predict how given conditions will lead to a particular behaviour and mental processes.
   • b. Involves knowledge of possible outcomes
4. Control
   • To mould behaviour in a particular direction
   • Involves the use of psychological principles and psychotherapeutic techniques

4. Give a historical account of the emergence of Psychology as a science.
Answer:

• Psychology is a vast field studying behavioural aspects of mankind and it started as a branch of Philosophy. It evolved as a separate branch in the 19th century.
• The first attempt to define Psychology was made based on the terminology. The word ‘Psychology’ is derived from two Greek words: ‘Psyche’ (soul or mind) and ‘Logos’ (science or branch of knowledge).
• Rational sciences establish facts based on observation and experimentation. However, neither soul nor mind can be observed. Hence, the definition of Psychology changed over time.
• In the late 19th century, Wilhelm Wundt established the first psychological laboratory at Leipzig University. He defined Psychology as the study of consciousness.
• Sigmund Freud defined Psychology as the study of the unconscious while John Watson defined it as ‘Science of human behaviour’.
• The latest definition of Psychology is the ‘Study of human behaviour and processes.’
• Psychology as a discipline evolved over time.

5. Describe the goals of Psychology.
Answer:

1. Describe
   • To precisely identify and classify behaviours and mental processes
   • Involves recording behaviour using various tools
2. Explain
   • To understand the causes of behaviour through meaningful explanation of facts
   • Involves the use of standardized tests
   • Behaviour observed in most people can be generalized
3. Predict
   • To predict how given conditions will lead to a particular behaviour and mental processes.
   • Involves knowledge of possible outcomes
4. Control

Activities

Activity 2. (Textbook Page No. 3)

Do you agree with the definition of Psychology as the Science which deals with the soul? If yes why? If no, why?
Answer:

• No, I don’t agree with this definition since the soul refers to the spiritual part of a person; which is believed to exist in some form even after death.
• Psychology is not a spiritual science. Since it studies the mental activities and behaviour of living beings, this definition seems to be incorrect.

Activity 3 (Textbook Page No. 3)

Collect information about Bahinabai Chaudhari: Mana (description of Mind)
Answer:

• Bahinabai Chaudhari (11 Aug 1880 – 3 Dec 1951) was an illiterate cotton farmer from the Jalgaon district in Maharashtra.
• She was a famous Marathi poet. Her poems captured the essence of her life, reflect the culture of the village and farming life, and present her wisdom.
• She has beautifully compared the mind with different aspects of nature such as wind, waves, butterflies, small particles, etc. The poet stressed that the mind is a unique creation of God and nothing in this world compares to it.

Activity 5 (Textbook Page No. 4)

Do you agree with the definition that Psychology is the study of the unconscious? What could be the limitations of this definition?
Answer:
I agree with the above definition because Psychology studies unconscious behaviour. A person himself may not be aware of unconscious aspects of his personality even when it may have a significant impact on his thoughts and behaviour. Psychology enables us to understand this unconscious side of human beings and hence, I agree with this definition. However, the limitation of the definition is the unconscious mind. It can’t be observed directly and hence is difficult to study it. Furthermore, Psychology is also concerned with the study of the conscious mind.

Activity 6 (Textbook Page No. 5)

• Instead, her moderate tension motivates her to study sincerely.
• She also knows that failure is a part and parcel of life and tries to learn from each mistake.
• Hence, she remains calm and confident even during the exam period.

(a) 36
(b) 54
(c) 18
(d) 27
Answer:
(b) 54

(II) Solve the following:

Question 1.
Let X ~ B(10, 0.2). Find
(i) P(X = 1)
(ii) P(X ≥ 1)
(iii) P(X ≤ 8).
Solution:
X ~ B(10, 0.2)
∴ n = 10, p = 0.2
∴ q = 1 – p = 1 – 0.2 = 0.8
The p,m.f. of X is given by

Question 2.
Let X ~ B(n, p).
(i) If n = 10, E(X) = 5, find p and Var(X).
(ii) If E(X) = 5 and Var(X) = 2.5, find n and p.
Solution:
X ~ B(n, p)
(i) Given: n = 10 and E(X) = 5
But E(X) = np
∴ np = 5.
∴ 10p = 5
∴ p = \(\frac{1}{2}\)
∴ q = 1 – p = 1 – \(\frac{1}{2}\) = \(\frac{1}{2}\)
Var(X) = npq = 10(\(\frac{1}{2}\))(\(\frac{1}{2}\)) = 2.5.
Hence, p = \(\frac{1}{2}\) and Var(X) = 2.5

(ii) Given: E(X) = 5 and Var(X) = 2.5
∴ np = 5 and npq = 2.5
∴ \(\frac{n p q}{n p}=\frac{2.5}{5}\)
∴ q = 0.5 = \(\frac{5}{10}=\frac{1}{2}\)
∴ p = 1 – q = 1 – \(\frac{1}{2}\) = \(\frac{1}{2}\)
Substituting p = \(\frac{1}{2}\) in np = 5, we get
n(\(\frac{1}{2}\)) = 5
∴ n = 10
Hence, n = 10 and p = \(\frac{1}{2}\)

Question 3.
If a fair coin is tossed 10 times and the probability that it shows heads (i) 5 times (ii) in the first four tosses and tail in the last six tosses.
Solution:
Let X = number of heads.
p = probability that coin tossed shows a head
∴ p = \(\frac{1}{2}\)
q = 1 – p = 1 – \(\frac{1}{2}\) = \(\frac{1}{2}\)
Given: n = 10
∴ X ~ B(10, \(\frac{1}{2}\))
The p.m.f. of X is given by
P(X = x) = \({ }^{n} C_{x} P^{x} q^{n-x}\)

(i) P(coin shows heads 5 times) = P[X = 5]

Hence, the probability that can shows heads exactly 5 times = \(\frac{63}{256}\)

(ii) P(getting heads in first four tosses and tails in last six tosses) = P(X = 4)

Hence, the probability that getting heads in first four tosses and tails in last six tosses = \(\frac{105}{512}\).

Question 4.
The probability that a bomb will hit a target is 0.8. Find the probability that out of 10 bombs dropped, exactly 2 will miss the target.
Solution:
Let X = the number of bombs hitting the target.
p = probability that bomb will hit the target
∴ p = 0.8 = \(\frac{8}{10}=\frac{4}{5}\)
∴ q = 1 – p = 1 – \(\frac{4}{5}\) = \(\frac{1}{5}\)
Given: n = 10
∴ X ~ B(10, \(\frac{4}{5}\))
The p.m.f. of X is given as:
P[X = x] = \({ }^{n} \mathrm{C}_{x} p^{x} q^{n-x}\)
i.e.p(x) = \({ }^{10} \mathrm{C}_{x}\left(\frac{4}{5}\right)^{x}\left(\frac{1}{5}\right)^{10-x}\)
P(exactly 2 bombs will miss the target) = P(exactly 8 bombs will hit the target)
= P[X = 8]
= p(8)

Hence, the probability that exactly 2 bombs will miss the target = 45\(\left(\frac{2^{16}}{5^{10}}\right)\)

Question 5.
The probability that a mountain bike travelling along a certain track will have a tire burst is 0.05. Find the probability that among 17 riders:
(i) exactly one has a burst tyre
(ii) at most three have a burst tyre
(iii) two or more have burst tyres.
Solution:
Let X = number of burst tyres.
p = probability that a mountain bike travelling along a certain track will have a tyre burst.
∴ p = 0.05
∴ q = 1 – p = 1 – 0.05 = 0.95
Given: n = 17
∴ X ~ B(17, 0.05)
The p.m.f. of X is given by
P(X = x) = \({ }^{n} \mathrm{C}_{x} P^{x} q^{n-x}\)
i.e.(x) = \({ }^{17} \mathrm{C}_{x}(0.05)^{x}(0.95)^{17-x}\), x = 0, 1, 2, ……, 17
(i) P(exactly one has a burst tyre)
P(X = 1) = p(1) = \({ }^{17} \mathrm{C}_{1}\) (0.05)¹ (0.95)^17-1
= 17(0.05) (0.95)¹⁶
= 0.85(0.95)¹⁶
Hence, the probability that riders has exactly one burst tyre = (0.85)(0.95)¹⁶

(ii) P(at most three have a burst tyre) = P(X ≤ 3)
= P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
= p(0) + p(1) + p(2) + p(3)


Hence, the probability that at most three riders have burst tyre = (2.0325)(0.95)¹⁴.

(iii) P(two or more have tyre burst) = P(X ≥ 2)
= 1 – P(X < 2)
= 1 – [P(X = 0) + P(X = 1)]
= 1 – [p(0) + p(1)]
= 1 – [\({ }^{17} \mathrm{C}_{0}\) (0.05)⁰ (0.95)¹⁷ + \({ }^{17} \mathrm{C}_{1}\) (0.05)(0.95)¹⁶]
= 1 – [1(1)(0.95)¹⁷ + 17(0.05)(0.95)¹⁶]
= 1 – (0.95)¹⁶[0.95 + 0.85]
= 1 – (1.80)(0.95)¹⁶
= 1 – (1.8)(0.95)¹⁶
Hence, the probability that two or more riders have tyre burst = 1 – (1.8)(0.95)¹⁶.

Question 6.
The probability that a lamp in a classroom will be burnt out is 0.3. Six such lamps are fitted in the classroom. If it is known that the classroom is unusable if the number of lamps burning in it is less than four, find the probability that the classroom cannot be used on a random occasion.
Solution:
Let X = number of lamps burnt out in the classroom.
p = probability of a lamp in a classroom will be burnt
∴ p = 0.3 = \(\frac{3}{10}\)
∴ q = 1 – p = 1 – \(\frac{3}{10}\) = \(\frac{7}{10}\)
Given: n = 6
∴ X ~ B(6, \(\frac{3}{10}\))
The p.m.f. of X is given as:
P[X = x] = \({ }^{n} \mathrm{C}_{x} p^{x} q^{n-x}\)
i.e., p(x) = \({ }^{6} \mathrm{C}_{x}\left(\frac{3}{10}\right)^{x}\left(\frac{7}{10}\right)^{6-x}\)
Since the classroom is unusable if the number of lamps burning in it is less than four, therefore
P(classroom cannot be used) = P[X < 4]
= P[X = 0] + P[X = 1] + P[X = 2] + P[X = 3]
= p(0) + p(1) + p(2) + p(3)

Hence, the probability that the classroom cannot be used on a random occasion is 0.92953.

Question 7.
A lot of 100 items contain 10 defective items. Five items are selected at random from the lot and sent to the retail store. What is the probability that the store will receive at most one defective item?
Solution:
Let X = number of defective items.
p = probability that item is defective
∴ p = \(\frac{10}{100}=\frac{1}{10}\)
∴ q = 1 – p = 1 – \(\frac{1}{10}\) = \(\frac{9}{10}\)
Given: n = 5
∴ X ~ B(5, \(\frac{1}{10}\))
The p.m.f. of X is given as:
P[X = x] = \({ }^{n} \mathrm{C}_{x} p^{x} q^{n-x}\)
i.e., p(x) = \({ }^{5} C_{x}\left(\frac{1}{10}\right)^{x}\left(\frac{9}{10}\right)^{5-x}\)
P (store will receive at most one defective item) = P[X ≤ 1]
=P[X = 0] + P[X = 1]
= p(0) + p(1)

Hence, the probability that the store will receive at most one defective item is (1.4)(0.9)⁴.

Question 8.
A large chain retailer purchases a certain kind of electronic device from a manufacturer. The manufacturer indicates that the defective rate of the device is 3%. The inspector of the retailer picks 20 items from a shipment. What is the probability that the store will receive at most one defective item?
Solution:
Let X = number of defective electronic devices.
p = probability that device is defective
∴ p = 3% = \(\frac{3}{100}\)
∴ q = 1 – p = 1 – \(\frac{3}{100}\) = \(\frac{97}{100}\)
Given: n = 20
∴ X ~ B(20, \(\frac{3}{100}\))
The p.m.f. of X is given as:

Hence, the probability that the store will receive at most one defective item = (1.57)(0.97)¹⁹.

Question 9.
The probability that a certain kind of component will survive a check test is 0.6. Find the probability that exactly 2 of the next 4 tested components tested survive.
Solution:
Let X = number of tested components survive.
p = probability that the component survives the check test

Hence, the probability that exactly 2 of the 4 tested components survive is 0.3456.

Question 10.
An examination consists of 10 multiple choice questions, in each of which a candidate has to deduce which one of five suggested answers is correct. A completely unprepared student guesses each answer completely randomly. What is the probability that this student gets 8 or more questions correct? Draw the appropriate moral.
Solution:
Let X = number of correct answers.
p = probability that student gets correct answer
∴ p = \(\frac{1}{5}\)
∴ q = 1 – p = 1 – \(\frac{1}{5}\) = \(\frac{4}{5}\)
Given: n = 10 (number of total questions)
∴ X ~ B(10, \(\frac{1}{5}\))
The p.m.f. of X is given by

Hence, the probability that student gets 8 or more questions correct = \(\frac{30.44}{5^{8}}\)

Question 11.
The probability that a machine will produce all bolts in a production run within specification is 0.998. A sample of 8 machines is taken at random. Calculate the probability that (i) all 8 machines (ii) 7 or 8 machines (iii) at most 6 machines will produce all bolts within specification.
Solution:
Let X = number of machines which produce the bolts within specification.
p = probability that a machine produce bolts within specification
p = 0.998 and q = 1 – p = 1 – 0.998 = 0.002
Given: n = 8
∴ X ~ B(8, 0.998)
The p.m.f. of X is given by
P(X = x) = \({ }^{n} \mathrm{C}_{x} p^{x} q^{n-x}\)
i.e. p(x) = \({ }^{8} \mathrm{C}_{x}(0.998)^{x}(0.002)^{8-x}\), x = 0, 1, 2, …, 8
(i) P(all 8 machines will produce all bolts within specification) = P[X = 8]
= p(8)
= \({ }^{8} \mathrm{C}_{8}\) (0.998)⁸ (0.002)^8-8
= 1(0.998)⁸ . (1)
= (0.998)⁸
Hence, the probability that all 8 machines produce all bolts with specification = (0.998)⁸.

(ii) P(7 or 8 machines will produce all bolts within i specification) = P (X = 7) + P (X = 8)

Hence, the probability that 7 or 8 machines produce all bolts within specification = (1.014)(0.998)⁷.

(iii) P(at most 6 machines will produce all bolts with specification) = P[X ≤ 6]
= 1 – P[x > 6]
= 1 – [P(X = 7) + P(X = 8)]
= 1 – [P(7) + P(8)]
= 1 – (1.014)(0.998)⁷
Hence, the probability that at most 6 machines will produce all bolts with specification = 1 – (1.014)(0.998)⁷.

Question 12.
The probability that a machine develops a fault within the first 3 years of use is 0.003. If 40 machines are selected at random, calculate the probability that 38 or more will develop any faults within the first 3 years of use.
Solution:
Let X = the number of machines who develop a fault.
p = probability that a machine develops a fait within the first 3 years of use
∴ p = 0.003 and q = 1 – p = 1 – 0.003 = 0.997
Given: n = 40
∴ X ~ B(40, 0.003)
The p.m.f. of X is given by

Hence, the probability that 38 or more machines will develop the fault within 3 years of use = (775.44)(0.003)³⁸.

Question 13.
A computer installation has 10 terminals. Independently, the probability that anyone terminal will require attention during a week is 0.1. Find the probabilities that (i) 0 (ii) 1 (iii) 2 (iv) 3 or more, terminals will require attention during the next week.
Solution:
Let X = number of terminals which required attention during a week.
p = probability that any terminal will require attention during a week
∴ p = 0.1 and q = 1 – p = 1 – 0.1 = 0.9
Given: n = 10
∴ X ~ B(10, 0.1)
The p.m.f. of X is given by
P(X = x) = \({ }^{n} \mathrm{C}_{x} p^{x} q^{n-x}\)
i.e. p(x) = \({ }^{10} C_{x}(0.1)^{x}(0.9)^{10-x}\), x = 0, 1, 2, …, 10
(i) P(no terminal will require attention) = P(X = 0)

Hence, the probability that no terminal requires attention = (0.9)¹⁰

(ii) P(1 terminal will require attention)

Hence, the probability that 1 terminal requires attention = (0.9)⁹.

(iii) P(2 terminals will require attention)

Hence, the probability that 2 terminals require attention = (0.45)(0.9)⁸.

(iv) P(3 or more terminals will require attention)

Hence, the probability that 3 or more terminals require attention = 1 – (2.16) × (0.9)⁸.

p = probability that pupils like Mathematics

(i) The probabilities of obtaining an answer yes from 0, 1, 2, 3, 4 of pupils are P(X = 0), P(X = 1), P(X = 2), P(X = 3) and P(X = 4) respectively

(ii) (a) P(visitor obtains the answer yes from at least 2 pupils when the number of pupils questioned remains at 4) = P(X ≥ 2)
= P(X = 2) + P(X = 3) + P(X = 4)

(b) P(the visitor obtains the answer yes from at least 2 pupils when number of pupils questioned is increased to 8)

Question 15.
It is observed that it rains 12 days out of 30 days. Find the probability that
(i) it rains exactly 3 days of the week.
(ii) it will rain at least 2 days of a given week.
Solution:
Let X = the number of days it rains in a week.
p = probability that it rains

(i) P(it rains exactly 3 days of week) = P(X = 3)

Hence, the probability that it rains exactly 3 days of week = 0.2903.

(ii) P(it will rain at least 2 days of the given week)

Hence, the probability that it rains at least 2 days of a given week = 0.8414

Solution:
Let X = number of successes.
p = probability of success in a single trial
∴ p = 0.01
and q = 1 – p = 1 – 0.01 = 0.99
∴ X ~ B(n, 0.01)
The p.m.f. of X is given by
P(X = x) = \({ }^{n} \mathrm{C}_{x} p^{x} q^{n-x}\)

Hence, the number of trials required in order to have a probability greater than 0.5 of getting at least one success is \(\frac{\log 0.5}{\log 0.99}\) or 68.

Question 17.
In binomial distribution with five Bernoulli’s trials, the probability of one and two success are 0.4096 and 0.2048 respectively. Find the probability of success.
