What is Psychology? | CBSE Class 11 Psychology Notes

This note covers the meaning of psychology, mental processes and behaviour, scientific enquiry, social context, major psychological approaches, the development of psychology in India, specialised branches, links with other disciplines, and applications in everyday life.

What does psychology study?

Definition: Psychology studies mental processes, experiences and behaviour scientifically within different contexts. It collects and interprets information systematically, drawing on methods from biological and social sciences.

The word psychology comes from the Greek words psyche, meaning soul, and logos, meaning science or study of a subject. Its earlier meaning as the study of the soul or mind differs from its present scientific scope.

A discipline is a field of knowledge identified by both its subject matter and its methods. Psychology examines individuals, dyadic or two-person relationships, groups and organisations. Psychological phenomena have biological as well as social bases, so different questions require different methods.

How do mental processes, experiences and behaviour differ?

Consciousness means awareness of one's experiences and mental processes. Experiences are subjective: they belong to the experiencing person. Understanding them requires attention to both internal conditions and external circumstances.

For example, on a crowded bus during a hot summer day, a person going for a picnic with close friends may not experience the usual discomfort. The physical conditions alone do not explain the experience.

Psychologists seek systematic, verifiable explanations while trying to minimise bias, the influence of personal viewpoints on interpretation. Some emphasise objective analysis, seeking explanations less influenced by personal viewpoints; others consider the experiencing person's viewpoint essential. Self-reflection, or examining one's own conscious experiences, has an important place in the Indian tradition.

How are mind, brain and behaviour related?

The brain is the physical organ whose activity provides clues about mental functioning. The mind emerges as interactions and experiences become organised into a system responsible for mental processes. Unlike the brain, it has no physical structure or location.

Mental processes and brain activities are interdependent and overlap, but they are not identical. Brain activity accompanies thinking and problem solving. Awareness of experience is nevertheless more than brain activity alone. Some mental activities continue during sleep, including dreaming and receiving information such as a knock.

What are overt and covert behaviours?

Overt behaviour can be seen or sensed outwardly by an observer. Covert behaviour is internal. Behaviour may be simple or complex, brief or enduring. Blinking when an object is hurled towards the eyes is a simple response; deciding to visit a cinema involves a different kind of activity.

A stimulus is an external event or internal change associated with a response. A response is the reaction or activity that follows. In stimulus-response notation, S means stimulus and R means response. Both can be internal or external.

Seeing a tiger and running illustrates an external stimulus. Thinking that a tiger is present and deciding to flee shows that an internal event can also be involved. Behaviour is therefore not restricted to visible movements caused by visible objects.

How can mental activity relate to bodily experience?

Mental imagery means images generated in the mind. A phantom arm is the felt presence of an arm that has been lost. The case of an athlete who continued to feel his missing arm and its movements illustrates the complexity of bodily experience.

Psychoneuroimmunology emphasises the mind's role in strengthening the immune system, the body's system of defence. The relationship between mind and behaviour is a subject of scientific study. Some scientists consider a unified theory of mind possible, although it is still far away.

How does psychology function as a natural science?

Psychology's roots lie in philosophy, enquiry into knowledge and human nature, but modern psychology developed through the use of scientific methods. Its natural science approach draws on physical and biological sciences to study behaviour systematically, often under controlled conditions.

This approach seeks causes, relationships between causes and effects, prediction and, where needed, control of behaviour. Objectivity can be obtained through agreement about what a concept means and how it can be measured, so explanations need more than a researcher's personal opinion.

What is the hypothetico-deductive model?

The hypothetico-deductive model moves from a theory to a testable explanation and then to evidence. A theory is a connected set of statements explaining a complex phenomenon. A hypothesis is a tentative explanation derived from that theory.

Empirical data are information gathered through observation or investigation. They are used to test a hypothesis. The relationship between explanation and evidence makes revision possible when observations point in a different direction.

1. Begin with a theory: use related propositions to explain the phenomenon being investigated.
2. Derive a hypothesis: propose a tentative explanation that follows from the theory.
3. Gather empirical data: collect information systematically to test whether the hypothesis is supported.
4. Revise when necessary: change the theory if the evidence points away from the explanation suggested by the hypothesis.

Most psychological research follows this approach. It has supported the development of theories concerning learning, memory, attention, perception, motivation and emotion. These involve acquiring knowledge, retaining it, attending to information, interpreting it, being moved to act and experiencing feelings.

The evolutionary approach explains behaviour in relation to biological evolution, the change in living species over time. Drawn from biological sciences, it also influences psychology. It has been used to explain phenomena such as attachment, the formation of emotional bonds, and aggression, behaviour intended to harm another person. Scientific psychology therefore draws on more than one way of explaining behaviour.

Why is psychology also a social science?

Psychology is generally categorised as a social science because it studies human beings within society and culture. A socio-cultural context includes the social relationships and cultural conditions within which a person lives. People both experience its influence and help create it.

From this perspective, behaviour is explained through interaction between the person and the surrounding context. Each behavioural phenomenon is assumed to have multiple causes. Individuals and communities are studied in relation to their social, cultural and physical environments.

What do Ranjita and Shabnam illustrate?

Ranjita lived with her farming family and enjoyed meeting people. She was a good athlete and her school's best long-distance runner. Shabnam lived with her mother, while her father worked in a nearby town. She enjoyed art and caring for her younger brother, and avoided meeting people.

When heavy rain flooded the village, villagers organised help and shelter. Shabnam's family stayed with Ranjita's family. Ranjita helped them feel comfortable, and her mother and grandmother later helped Shabnam's mother set up their home again. The families grew close, and the girls became good friends.

Their different family situations and shared experience help explain their relationship. Yet not every villager was equally helpful. Under similar circumstances, not every community offers help; sometimes people engage in looting and exploitation instead. Context matters, but prediction remains difficult.

These are parallel streams within psychology. Their methods sometimes converge and sometimes move apart. Recognising both helps retain the biological and social dimensions of human functioning.

How does scientific psychology differ from common sense?

People often offer ready explanations of others' behaviour. Such common-sense explanations may or may not survive scientific investigation. They frequently depend on hindsight, explaining an event after its outcome is known, rather than identifying patterns that permit prediction.

Two familiar sayings offer opposite accounts of separation from a friend: “Out of sight, out of mind” and “Distance makes the heart grow fonder”. Either may seem convincing after the event. Selecting the saying that fits an outcome does not establish a predictive explanation.

What did Dweck's study investigate?

Dweck's 1975 study examined children who gave up too easily after difficulty or failure. A common-sense expectation was that easy problems would increase success and confidence, preparing children for harder tasks.

The result challenged the belief that uninterrupted success best prepares children to handle difficulty. The second group's experience included both success and failure, together with encouragement to connect failure with lack of effort. Both features matter in explaining the comparison.

Note: Scientific knowledge often runs against common sense, but this does not mean every common-sense belief is false. The important difference is systematic examination using evidence.

Similarly, performing before an audience does not necessarily reduce performance. If someone has practised well, the presence of others may actually improve performance. The qualification about practice is essential; the finding does not promise improvement in every situation.

Psychologists test propositions against data to develop principles. This distinguishes their work from palm reading or other claims that do not follow this systematic process.

How did the early schools of psychology develop?

Modern psychology's formal beginning is traced to Wilhelm Wundt's laboratory, established in Leipzig, Germany, in 1879. Earlier philosophical questions about human nature became subjects of experimental investigation. Different schools then proposed different answers about what psychology should study.

What was structuralism?

Structuralism sought the building blocks of conscious experience. Its method, introspection, required participants to describe their own mental processes and experiences in detail. Psychologists using this method tried to analyse the structure of the mind.

The reports could not be verified by outside observers. Many psychologists therefore considered introspection less scientific. This limitation contributed to the emergence of alternative perspectives rather than ending enquiry into mental life.

How did functionalism and Gestalt psychology differ?

Functionalism, associated with William James, asked what the mind does and how behaviour helps people deal with their environment. James viewed consciousness as an ongoing stream interacting with the environment. John Dewey used functionalism to explain effective adaptation to surroundings.

Gestalt psychology studied the organisation of perceptual experience, meaning how sensory information is experienced as an organised whole. A Gestalt is a holistic experience. The whole experience is more than the sum of its component inputs.

Flashing bulbs can produce an experience of movement. Likewise, a movie presents rapidly changing still pictures, yet the viewer experiences movement. These examples show why describing separate elements does not fully describe the resulting experience.

What did behaviourism change?

Behaviourism made observable, measurable responses its subject matter. Around 1910, John Watson rejected mind and consciousness as the proper objects of scientific psychology because they could not be independently observed and verified.

Watson was influenced by Ivan Pavlov's work on learning responses through associations, called classical conditioning. Skinner later developed and popularised behaviourism across a wide range of situations.

What did psychoanalytic, humanistic and cognitive approaches add?

Psychology developed through multiple perspectives rather than a single explanation of human nature. Each perspective directs attention to particular aspects of functioning and has strengths as well as weaknesses. These approaches are not mutually exclusive.

How do psychoanalysis and humanism view people?

Psychoanalysis, founded by Sigmund Freud, is a system for understanding and treating psychological disorders, or disturbances in psychological functioning. Freud explained behaviour through unconscious desires and conflicts, those outside conscious awareness. He emphasised pleasure-seeking desires, often sexual ones.

The humanistic approach took a more positive view of human nature. Carl Rogers and Abraham Maslow emphasised free will, growth and the unfolding of inner potential. Free will here means human freedom to choose, rather than behaviour being determined entirely by environmental conditions.

Humanists criticised behaviourism's mechanistic view of people, in which environmental conditions determine behaviour. They argued that this view undermined human freedom and dignity. Their own emphasis was on the desire to grow, become productive and fulfil human potential.

What are cognition and constructivism?

Cognition is the process of knowing. It includes thinking, understanding, remembering, solving problems and interpreting information. The cognitive approach puts these processes at the centre of psychological explanation.

Some cognitive psychologists compare the mind with an information-processing system. It receives, processes, transforms, stores and retrieves information. This is one way of understanding mental activity, rather than a claim that the mind is literally a computer.

Constructivism views people as actively constructing their minds through exploration of the physical and social world. Piaget's account of child development is considered constructivist because children actively build their own understanding.

Vygotsky placed greater emphasis on social and cultural processes. He viewed the mind as a joint cultural construction emerging through interactions between adults and children. The contrast concerns how construction occurs, rather than whether development involves activity.

Contemporary psychology is multivocal, meaning it contains several explanatory voices or perspectives. Biological, behavioural, cognitive and social explanations can illuminate different levels of a complex psychological phenomenon.

How did psychology develop in India?

Indian philosophical traditions have long examined consciousness, the self, mind-body relations and mental functions. Modern psychology in India, however, developed largely under western influence. Efforts to connect it with Indian traditions have included scientific investigation of traditional claims.

What were the early institutional developments?

At Calcutta University, the first experimental psychology syllabus and psychology laboratory were introduced in 1915. The first Department of Psychology followed in 1916, and a Department of Applied Psychology in 1938.

N.N. Sengupta, trained in the United States in Wundt's experimental tradition, influenced early experimental psychology. G. Bose, trained in Freudian psychoanalysis, established the Indian Psychoanalytical Association in 1922. Mysore and Patna universities were other early centres of teaching and research.

What were Durganand Sinha's four phases?

In his 1986 book, Psychology in a Third World Country: The Indian Experience, Durganand Sinha identified four phases in the development of modern psychology as a social science in India.

Indigenisation means developing psychological understanding rooted in the local social and cultural context. This phase included both indigenous psychology arising from Indian cultural life and Indian psychology drawing on traditional knowledge in ancient texts and scriptures.

The distinction matters: culturally relevant research need not be identical to the study of traditional ideas. Both contributed to the search for an identity that responded to Indian society.

Psychology in India has also developed connections with biological and health sciences. Its applications extend to hospitals, organisations, advertising, sports, development work and information technology. These developments combine attention to local conditions with contributions to wider psychological knowledge.

Which branches study knowing, development and social life?

Specialised branches address different questions about human functioning. They develop their own theories and methods, while frequently collaborating with other fields. A branch's focus helps identify the questions its researchers ask.

How do cognitive and biological psychology differ?

Cognitive psychology investigates how information is acquired, stored, changed, used and communicated. Its concerns include attention, memory, reasoning, decision-making and language. Reasoning involves using thought to reach conclusions; decision-making involves choosing between possibilities; language enables communication. Researchers use laboratory experiments; some also use an ecological approach, examining environmental influences in natural settings.

Biological psychology studies relationships between behaviour and physical systems, including the brain, nervous system, immune system and inherited characteristics. It often involves collaboration with scientists studying the nervous system, animals and human communities.

Neuropsychology brings psychologists and scientists studying the nervous system together to investigate brain-behaviour relationships. They study both normally functioning and damaged brains. Neurotransmitters are chemical substances responsible for communication within the nervous system and are studied in relation to mental functions.

How do development, society and culture shape enquiry?

Developmental psychology studies physical, social and psychological changes across the life-span, from conception to old age. Its question is how people become what they are. Adult development and ageing receive increasing attention alongside childhood and adolescence.

Social psychology examines how people are affected by social environments, think about others and influence one another. Its interests include helpful behaviour, attraction between people, aggression, obedience to authority and relationships between groups.

Cross-cultural and cultural psychology examines culture's role in behaviour, thought and emotion. Behaviour reflects biological potential and is also a product of culture. It therefore needs to be understood within its socio-cultural context.

These branches overlap without becoming identical. Developmental enquiry focuses on change across life; social enquiry examines interpersonal influence; cultural enquiry asks how cultural conditions shape psychological functioning. Cognitive and biological research add different perspectives on the processes involved.

How do applied branches help in different settings?

Applied psychology uses psychological knowledge to address practical problems. Its fields include health, education, workplaces, sport and the physical environment. Their concerns extend from understanding problems to designing ways of improving people's functioning.

Which branches address health and personal difficulties?

Health psychology examines psychological factors in the development, prevention and treatment of illness. It studies stress, meaning strain associated with demanding situations, and coping, meaning ways of managing such demands. Other concerns include patient-doctor relationships and health-promoting behaviour.

Clinical psychology deals with the causes, treatment and prevention of psychological disorders. Counselling psychology helps people solve daily problems and cope with challenging situations to improve everyday functioning. It may include support with personal problems and career planning.

Note: Clinical and counselling work overlaps. A counselling psychologist sometimes works with people who have less serious problems; this is not a rigid division between two completely separate kinds of work.

How are environment, work, education and sport studied?

Environmental psychology studies relationships between physical surroundings and behaviour. Topics include temperature, humidity, pollution, disasters and workplace arrangements. It also examines behaviour associated with waste disposal, energy conservation and the use of community resources.

Industrial/organisational psychology examines workers and their employing organisations. It addresses employee selection and training, working conditions and communication. An organisational psychologist might recommend changes in management structure to improve communication between managers and staff.

Educational psychology studies learning across ages and helps develop teaching methods and materials for educational and work settings. School psychology applies psychological knowledge in schools through programmes supporting children's intellectual, social and emotional development, including children with special needs.

Sports psychology applies psychological principles to improve sporting performance by enhancing motivation, the processes that energise and direct action. The variety of applied fields shows why psychology cannot be reduced to counselling alone.

How is psychology linked with other disciplines?

An interdisciplinary approach brings knowledge from different fields together to understand a problem. Psychology exchanges ideas with biological sciences, social sciences, humanities and practical professions. The relationship involves contributions in both directions.

A central circle labelled Psychology is surrounded by labelled illustrations for Political Science, Education, Economics, Philosophy, Music and Fine Arts, Computer Science, Law/Criminology, Medicine/Psychiatry, Mass Communication, Architecture and Engineering, and Sociology. Lines radiate from the central circle towards surrounding labels.

See Fig. 1.1 in your NCERT textbook

What do the major connections involve?

In legal contexts, remembering an event and accurately reporting it are important questions. Psychological research examines what influences witness reports and legal decisions. These are questions for investigation, rather than reasons to assume that memory is a perfect record.

How do arts and design use psychological understanding?

Music and psychology meet in research on work performance and emotions. Music therapy refers here to attempts to use musical forms to treat ailments. Its efficacy, or effectiveness, still remains to be proven. This qualification must accompany claims about its use.

Architecture, the design of buildings and spaces, considers clients' mental and physical needs as well as their sense of beauty. Engineering, the design of practical structures and devices, takes human habits into account in safety planning, mechanical devices and displays.

Across these connections, psychology contributes an understanding of people. Other disciplines contribute knowledge about the physical, social and cultural conditions within which people act.

How can psychology contribute to everyday life?

Psychology can help address problems at personal, family, community and wider social levels. Its applications include education, health, environmental problems, social justice and relationships between groups. Solutions may require political, economic and social reforms alongside changes at the individual level.

Unhealthy thinking, negative attitudes towards oneself or others, and undesirable behaviour patterns can contribute to problems. Psychological analysis helps clarify such patterns and develop effective responses. It does not make the broader social circumstances irrelevant.

How can psychological knowledge support self-understanding?

Defensive behaviour includes rejecting feedback that contradicts an excessively favourable view of oneself. Habitually putting oneself down creates another obstacle to growth. A positive and balanced understanding of oneself is preferable to either pattern.

Psychological principles can support better study habits, learning and memory. They can also help with decision-making, personal and interpersonal problems, and examination stress. Their personal value lies in understanding oneself in relation to others and using that understanding constructively.

Where do psychologists contribute professionally?

Psychologists work in schools, hospitals, industries, prisons, business organisations and military settings, as well as private practice. Intervention programmes are organised efforts to address problems and improve quality of life. Many psychologists help design and carry out these programmes.

The range of work reflects the range of psychological questions. Knowledge about learning supports education; knowledge about workplace behaviour supports organisations; understanding relationships can help families and communities. Psychology contributes both theoretical explanations and practical responses to difficulties in daily life.

Common errors and misconceptions

• Misconception: Psychology still means only the study of the soul. Correct: That is its historical meaning; its scientific scope includes mental processes, experiences and behaviour.
• Misconception: Mind and brain are identical. Correct: Mental processes and brain activities are interdependent and overlap, but are not identical.
• Misconception: Behaviour must be visible, and stimuli must be external. Correct: Behaviour may be overt or covert, and stimuli and responses can be internal or external.
• Misconception: Common sense reliably predicts behaviour. Correct: Common-sense accounts often rely on hindsight; their claims may or may not withstand empirical investigation.
• Misconception: Structuralism and functionalism ask the same question. Correct: Structuralism examines mental components; functionalism examines what mind and behaviour do in adaptation.
• Misconception: Counselling and clinical psychology are entirely separate. Correct: Their work overlaps, although counselling psychologists sometimes deal with less serious problems.
• Misconception: Developmental psychology studies children alone. Correct: It studies change across the life-span, including adulthood and old age.

Exam-style questions with model answers

Q1. A person blinks when an object is hurled towards the eyes. Another person internally decides to flee after thinking a tiger is nearby. Behaviour may be outwardly observable or internal. Classify the blink and the internal decision, explaining each classification. [2 marks]

1. The blink is overt behaviour because an observer can see the person's outward response to the approaching object.
2. The internal decision is covert behaviour because it occurs within the person rather than being an outwardly observable action.

Q2. A researcher starts with connected statements explaining a phenomenon, derives a tentative explanation, tests it using collected observations, and revises the original explanation when evidence disagrees. Explain these four stages using the terms theory, hypothesis, empirical data and revision. [4 marks]

1. A theory is the starting set of interconnected statements that explains the phenomenon and gives the investigation its framework.
2. A hypothesis is the tentative explanation derived from that theory, which is put forward for testing rather than accepted without investigation.
3. Empirical data are the observations collected to examine whether the proposed hypothesis is supported by evidence.
4. Revision changes the theory when the collected data point in a direction different from the hypothesis, keeping the explanation responsive to evidence.

Q3. Ranjita enjoyed meeting people and lived with her farming family. Shabnam avoided meeting people and lived with her mother while her father worked in a nearby town. During a flood, Ranjita's family sheltered Shabnam's family, and the girls became close friends. Explain three ways this account illustrates psychology as a social science. [3 marks]

1. The girls' different family settings show why behaviour is studied within social circumstances rather than treated as isolated from people's surroundings.
2. The flood and shared accommodation connect a physical event with changing social relationships, showing interaction between people and their context.
3. Their growing friendship illustrates how shared experiences and interaction can shape relationships. Understanding the change requires attention to the social experience described.

Q4. In Dweck's 1975 study, two groups practised mathematics for 25 days. One received only easy problems and always succeeded. The other received easy and difficult problems; after failure, children were encouraged to keep trying and attribute failure to insufficient effort. On new problems, the first group gave up much faster after failure. Explain five features or implications of this study for the distinction between science and common sense. [5 marks]

1. The study tested a common-sense expectation that repeated success with easy problems would build confidence and prepare children to face later difficulty.
2. The first group's training provided success throughout the 25 days, so it represented the expectation that easy tasks alone would be helpful.
3. The second group encountered both success and failure and received encouragement to persist and connect failure with insufficient effort. These details belong together.
4. When new problems produced failure, the first group gave up much faster. The observed result therefore challenged the expectation favouring uninterrupted success.
5. The conclusion came from comparing evidence rather than choosing a convenient explanation after an everyday event. It illustrates why common-sense claims need scientific testing.

Q5. Consider six perspectives: structuralism analyses mental components through introspection; functionalism studies adaptation; Gestalt psychology studies organised wholes; behaviourism examines observable responses; psychoanalysis emphasises unconscious desires and conflicts; humanism emphasises free will and growth. Explain the distinctive focus of each perspective in six separate points. [6 marks]

1. Structuralism asks what conscious experience consists of. Through introspection, people describe their own mental processes so that the components of experience can be analysed.
2. Functionalism asks what the mind does. It examines the functions of behaviour, especially how behaviour helps people adapt and deal with their environment.
3. Gestalt psychology examines experience as an organised whole. It argues that describing separate component inputs does not fully account for the experience itself.
4. Behaviourism focuses on observable responses that can be measured and independently checked. It makes such behaviour the basis of scientific psychological enquiry.
5. Psychoanalysis explains behaviour through desires and conflicts outside conscious awareness. Its focus directs attention to influences that a person does not consciously recognise.
6. Humanism emphasises freedom to choose and the striving to grow. It highlights people's capacity to become productive and unfold their inner potential.

Q6. Sinha identified four phases: experimental, psychoanalytic and testing research till independence; expansion using western ideas in Indian settings till the 1960s; problem-oriented research after the 1960s; and indigenisation beginning in the late 1970s. Explain the change in emphasis across these four phases. [4 marks]

1. The early phase primarily reflected western developments through experimental work, psychoanalytic research and psychological testing, rather than an independent culturally rooted framework.
2. The expansion phase developed different branches while seeking an Indian identity by applying western psychological ideas to Indian situations.
3. The problem-oriented phase turned attention towards Indian social problems and recognised limitations in excessive reliance on western psychology.
4. Indigenisation sought socially and culturally relevant frameworks rooted in India, strengthening the effort to develop understanding suited to Indian conditions.

Q7. Environmental psychology examines physical surroundings and behaviour; educational psychology studies learning and teaching materials; industrial/organisational psychology studies workers and organisations. Select and justify a branch for each problem: behaviour associated with waste disposal, improving instructional materials, and improving communication between managers and staff. [3 marks]

1. Environmental psychology fits waste disposal because it studies how human behaviour relates to physical surroundings and the use of community resources.
2. Educational psychology fits instructional materials because it studies how people learn and helps develop methods and materials for teaching and training.
3. Industrial/organisational psychology fits communication between managers and staff because its focus includes workplace behaviour and improvements in the organisations employing workers.

Q8. A clinical psychologist has a psychology degree with intensive training in treating psychological disorders. A psychiatrist has a medical degree and specialised training, and can prescribe medicines and give electroshock treatment; a clinical psychologist cannot. State two differences. [2 marks]

1. The clinical psychologist's training begins with psychology, whereas the psychiatrist's training begins with a medical degree and continues with specialisation.
2. The psychiatrist can prescribe medication and give electroshock treatment, while the clinical psychologist cannot provide these medical treatments.

Test yourself

What does dyadic mean?

Dyadic means involving two people, as in a two-person relationship studied by psychology.

What do S and R represent in stimulus-response notation?

S represents stimulus and R represents response; either can be internal or external.

Why was introspection considered less scientific by many psychologists?

Reports described personal mental experiences that outside observers could not independently verify.

What does the Gestalt approach add to the study of perception?

It emphasises organised experience as a whole that exceeds the sum of its separate component inputs.

How do Piaget and Vygotsky differ in explaining the construction of mind?

Piaget emphasises children's active construction; Vygotsky emphasises joint cultural construction through interactions between children and adults.

When were Calcutta University's first psychology laboratory and Department of Psychology established?

The laboratory was established in 1915, followed by the Department of Psychology in 1916.

Does developmental psychology stop at adolescence?

No. It studies physical, social and psychological change across the life-span, including adulthood and old age.

What two patterns obstruct balanced self-understanding?

Rejecting feedback to defend an excessively favourable self-image and habitually putting oneself down both obstruct personal growth.
