NCERT Solutions for Class 12 Psychology - Meeting Life Challenges

Q1: Explain the concept of stress. Give examples from daily life.
Ans: Stress is derived from the Latin word 'strictus', which means tight or narrow. It is the pattern of responses an organism makes to a stimulus event that disturbs equilibrium and exceeds a person's ability to cope. Stress mobilises energy and increases arousal, which may enhance performance up to a point. However, very high levels of stress can produce unpleasant effects and impair performance, while too little stress may lead to listlessness and low motivation. Not all stress is harmful; some stress can be motivating and help people meet demands. 
Examples from daily life include:

• Attending parties may be stressful for someone who prefers quiet evenings at home, because it demands social energy and adjustment.
• Receiving lower marks than expected can produce frustration and stress, prompting worry about future consequences.
• Being forced to choose a job because of family pressure may create significant stress owing to conflicting personal goals and external expectations.

Q2: State the symptoms and sources of stress.
Ans: Symptoms of stress
Stress symptoms may be physical, emotional, cognitive and behavioural. Common symptoms include:

• Physical: headaches, muscle tension, rapid heartbeat, sleep disturbance, fatigue and gastrointestinal problems.
• Emotional: irritability, anxiety, mood swings, sadness or feeling overwhelmed.
• Cognitive: poor concentration, indecision, forgetfulness and negative thinking.
• Behavioural: changes in appetite, increased use of alcohol or tobacco, social withdrawal and increased absenteeism.

Sources of stress: Common sources include:

• Major life events: bereavement, serious illness, job loss, marriage or moving house.
• Daily hassles: traffic, work deadlines, household chores and arguments.
• Chronic stressors: ongoing financial problems, long-term illness and caregiving responsibilities.
• Traumatic events: accidents, natural disasters and violence.
• Environmental: noise, crowding, pollution and extreme climate.

Q3: Describe the GAS model and illustrate the relevance of this model with the help of an example.
Ans: Hans Selye studied the body's response to prolonged stress by exposing animals to various stressors and by observing patients with different injuries and illnesses. He found a consistent pattern of response which he termed the General Adaptation Syndrome (GAS). GAS consists of three stages:

• Alarm Reaction Stage: The presence of a noxious stimulus activates the body's emergency systems and triggers the release of hormones that prepare the individual for fight or flight.
• Resistance Stage: If the stress continues, the body attempts to cope by conserving and efficiently using resources; the organism resists the stressor and tries to adapt.
• Exhaustion Stage: Prolonged exposure to the same stressor or the addition of new stressors depletes physiological resources, making the individual vulnerable to illness, for example high blood pressure or other stress-related disorders.

Example illustrating GAS: A student facing a major exam may initially experience an alarm reaction-feeling anxious and alert. With continued study and coping, the student enters the resistance stage and functions effectively for a period. If study demands remain intense without adequate rest, the student may reach exhaustion, showing fatigue, poor concentration and illness. While Selye's model highlights physiological stages, it has been criticised for underemphasising psychological appraisal; how a person interprets a stressor (their perception, personality and support) greatly affects the course of GAS.

Q4: Enumerate the different ways of coping with stress.
Ans: To manage stress we can reassess our thinking and learn effective coping strategies. Common coping approaches include:

• Task-oriented strategy: Gather information, set priorities and take direct action to solve problems. Practical examples are making a timetable, breaking a large task into smaller parts, and seeking advice to find alternative solutions.
• Emotion-oriented strategy: Manage emotional responses by accepting feelings, expressing them appropriately, or using relaxation techniques. Examples include talking about worries with a friend, practising deep breathing, or reminding oneself that some things are beyond control.
• Avoidance-oriented strategy: Temporarily deny or minimise the seriousness of a situation to reduce immediate distress. This can be adaptive short term (for instance, taking a break by watching a film or calling a friend) but may be harmful if it prevents facing persistent problems.

Q5: Explain the effect of stress on psychological functioning.
Ans:  The effect of stress on psychological functioning can be understood under several headings:

• Emotional effects: Stress often leads to mood swings, irritability and anxiety, which may strain relationships and reduce confidence, possibly progressing to depression if prolonged.
• Physiological effects: Stress triggers hormones such as adrenaline and cortisol, producing changes in heart rate, blood pressure and metabolism. Short-term changes can be helpful, but chronic activation may harm health.
• Cognitive effects: High stress impairs concentration, decision-making and short-term memory, increasing the likelihood of mistakes and poor judgements at work or home.
• Behavioural effects: Stress can change behaviour, causing disturbed sleep, altered appetite, increased use of stimulants (for example caffeine) or substances (for example alcohol, tobacco) and reduced work performance.

Q6: Describe how life skills can help meet life's challenges.
Ans: Life skills are abilities that support adaptive and positive behaviour, helping individuals handle day-to-day challenges and maintain balance. These skills can be learned and strengthened. 
Important life skills include:

• Assertiveness: Communicating needs and boundaries clearly helps prevent misunderstandings and reduces stress from unresolved conflicts.
• Time management: Prioritising tasks and planning prevents last-minute pressure and improves productivity.
• Rational thinking: Evaluating problems calmly and realistically reduces catastrophic thinking and supports better decisions.
• Improving relationships: Building supportive social ties provides emotional support and practical help in times of need.
• Self-care: Regular sleep, balanced diet and exercise help maintain physical and mental resilience.
• Overcoming unhelpful habits: Reducing perfectionism and procrastination lowers unnecessary pressure and increases satisfaction.

By developing these skills, individuals become better equipped to meet life's challenges and recover from setbacks.

Q7: Discuss the factors that lead to positive health and well-being.
Ans: Various factors contribute to positive health, which is a state of complete physical, mental, social and spiritual well-being. Key factors that promote positive health include:

• Balanced diet: Adequate nutrients support energy, growth and repair.
• Regular exercise: Physical activity improves mood, cardiovascular fitness and immunity.
• Good sleep: Restorative sleep aids cognitive function and physical recovery.
• Positive attitude and meaning: A sense of purpose and optimism increase resilience to stress.
• Strong social support: Family and community networks buffer the effects of stress and provide practical help.
• Effective coping skills: Problem-solving and emotion regulation reduce the impact of chronic stress.
• Preventive healthcare: Vaccination, routine screening and timely medical care prevent and detect illness early.

Q8: How does stress affect the immune system?
Ans:  Stress can impair the immune system and increase susceptibility to illness. Psychoneuroimmunology studies links between the mind, brain and immune system. White blood cells (leucocytes) identify and destroy foreign bodies (antigens) and produce antibodies. 
Important cell types include:

• T cells: Destroy invaders; T-helper cells enhance immune activity.
• B cells: Produce antibodies.
• Natural killer cells: Fight viruses and tumours.

Chronic or severe stress can reduce the effectiveness (for example, cytotoxicity) of natural killer cells and other immune responses. Observed declines in immune function occur in people under heavy stress, such as students during important examinations, the bereaved and those with severe depression. Social support and effective coping are linked with better immune functioning. Changes in immunity from stress have a larger effect on those whose immune systems are already weakened.

Q9: Give an example of a life event which is likely to be stressful. Suggest reasons why it is likely to cause different degrees of stress to the person experiencing it.
Ans:  Major life events that disturb routine and cause upheaval are often stressful. 
Examples include:

• Unexpected accidents or trauma.
• Death of a close family member.

The degree of stress experienced varies between individuals because of factors such as:

• Age at first experience: Younger or older persons may have fewer coping resources for certain events.
• Frequency: Repeated occurrences increase cumulative stress.
• Duration: Longer exposure to the stressful condition produces greater strain.
• Social support: Availability of family, friends or community help reduces perceived threat and eases coping.

Thus, the same life event can cause different levels of stress depending on personal and contextual factors.

Q10: Given what you know about coping strategies, what suggestions would you give to your friends to avoid stress in their everyday lives.
Ans: Coping is a situation-specific response to stress. I would recommend a mix of problem-focused and emotion-focused strategies:

• Use problem-focused strategies: Make realistic plans, set priorities, break tasks into small steps and seek information or help when needed.
• Apply emotion-focused strategies: Use relaxation techniques (for example deep breathing), talk about feelings with a trusted friend and accept what cannot be changed.
• Maintain regular routines: Healthy sleep, balanced meals and daily activity reduce vulnerability to stress.
• Build social support: Keep in touch with family and friends and ask for help when necessary.
• Limit harmful coping: Avoid relying on alcohol, excessive caffeine or other substances to manage stress.
• Improve time management: Avoid procrastination and allow short breaks to prevent burnout.

Combining these approaches helps reduce everyday stress and improves resilience.

Q11: Reflect on the environmental factors that have (a) a positive impact on the being, and (b) a negative effect.
Ans: (a) Environmental factors that have a positive impact include well-run social and public campaigns, fair and supportive governmental policies, urban greening and plantation of trees, accessible medical and preventive health services, and clean public spaces. These factors improve physical health, mental well-being and community resilience.
(b) Environmental factors with a negative impact include air pollution, crowding, excessive noise, extreme temperatures, and catastrophic events such as fires, earthquakes and floods. Such factors increase physical stress, reduce life quality and can lead to both short-term and long-term health problems.

Q12: We know that certain lifestyle factors can cause stress and may lead to diseases like cancer and coronary heart disease, yet we are unable to change our behaviour. Explain why?
Ans: Reasons why unhealthy behaviours persist despite known risks include:

• Immediate rewards vs delayed costs: Unhealthy habits (comfort eating, smoking, excess drinking) offer short-term relief or pleasure, while harmful consequences appear much later.
• Addiction and habit formation: Biological addiction (for example nicotine or alcohol) and learned routines are difficult to break.
• Low self-efficacy: People may doubt their ability to change and so avoid attempting sustained change.
• Social and cultural influences: Peer pressure, family habits and social norms reinforce unhealthy choices.
• Stress undermines change: High stress reduces motivation and self-control, creating a cycle of unhealthy coping.
• Underestimation of risk: Cognitive biases lead people to minimise personal vulnerability and postpone change.

Promoting lasting change requires addressing addiction, improving self-efficacy, providing social support, restructuring environments to make healthy choices easier, and offering accessible education and interventions.
