PSYCHOLOGY CLASS 11 – CHAPTER 1
WHAT IS PSYCHOLOGY?
1. INTRODUCTION
- Psychology is the scientific study of human behaviour, mental processes, and experiences.
- It attempts to understand how people think, feel, and act in different situations.
- The word psychology originates from two Greek words:
- Psyche = soul/mind
- Logos = study/discourse
- Earlier, psychology was defined as the “study of the soul,” later as the “study of the mind,” and now as the scientific study of behaviour and mental processes.
- Psychology helps us understand why people are different, why they behave similarly in some situations, and what factors shape human behaviour.
- Modern psychology is evidence-based, objective, and uses scientific methods such as observation, surveys, experiments, and case studies.
- Psychology is applied in many fields—education, health, business, sports, environment, and more.
- It also helps people understand themselves, improve relationships, reduce stress, and solve daily problems.
- The discipline has evolved from philosophical roots to an empirical science.
- Today, psychology focuses on real-life issues and contributes to individual and societal well-being.
2. WHAT IS PSYCHOLOGY?
- Psychology is commonly defined as the science of behaviour and mental processes.
- Behaviour includes:
- Overt (visible) actions → walking, talking, eating
- Covert (internal) actions → thinking, remembering, imagining
- Mental processes refer to internal, private experiences such as:
- Thoughts
- Feelings
- Motives
- Memories
- Perceptions
- Psychology uses scientific methods—objective, controlled, systematic procedures.
- Psychologists collect data to understand the “what,” “how,” and “why” of behaviour.
- Psychology aims to describe, explain, predict, and control behaviour.
- Psychology is not limited to abnormal behaviour; it studies normal, everyday behaviour too.
- It focuses on both individual differences and similarities among human beings.
- Psychology emphasises measurable evidence instead of assumptions or guesswork.
- It helps in understanding both humans and animals to learn about behaviour patterns.
3. UNDERSTANDING MIND AND BEHAVIOUR
3.1 The Mind
- The mind refers to internal mental processes.
- It cannot be directly observed—only inferred through behaviour.
- It includes perceptions, memory, imagination, thinking, reasoning, emotions, and decision-making.
3.2 Behaviour
- Behaviour is any observable action made by an organism.
- It can be voluntary (talking) or involuntary (blinking).
- Behaviour is influenced by biological, social, cultural, and situational factors.
3.3 Relationship between Mind and Behaviour
- Behaviour reflects what is going on inside the mind.
- Internal mental states (motives/emotions) influence outward behaviour.
- Understanding behaviour helps psychologists infer mental processes.
3.4 Factors Influencing Behaviour
- Biological factors – genes, hormones, brain structure.
- Psychological factors – motives, attitudes, feelings, personality.
- Social factors – family, peers, culture, society.
- Environmental factors – weather, crowding, noise.
3.5 Human Behaviour Characteristics
- Purposeful and goal-oriented.
- Adaptive – helps survive in changing environments.
- Dynamic – changes with time and experiences.
- Influenced by learning and conditioning.
3.6 Psychology as a Science
- Uses systematic observation.
- Collects data objectively.
- Uses statistical analysis.
- Relies on theories and empirical evidence.
4. POPULAR NOTIONS ABOUT THE DISCIPLINE OF PSYCHOLOGY
4.1 Common Misconceptions
- Psychology is only about “reading minds.”
- Psychology deals only with mental disorders.
- Psychologists use intuition, not science.
- Psychology is the same as psychiatry.
- Psychologists give advice to everyone like counsellors.
- Psychology is only about common sense.
4.2 Why These Notions Are Incorrect
- Psychologists cannot read minds; they infer mental processes through data.
- Psychology studies normal behaviour more than abnormal behaviour.
- It is a scientific discipline relying on experiments, observations, tests.
- Psychiatrists are medical doctors; psychologists are not necessarily doctors.
- Psychologists are trained to apply theories, not just give advice.
- Common sense lacks systematic testing; psychology uses scientific methods.
4.3 Sources of Misconceptions
- Films and media portray psychologists unrealistically.
- Lack of awareness about the scientific nature of psychology.
- Cultural beliefs about mind, soul, and behaviour.
- Social myths regarding mental health.
4.4 How Psychology Differs from Common Sense
- Common sense is subjective; psychology is objective.
- Common sense varies across cultures; scientific principles are universal.
- Common sense depends on personal opinions; psychology uses evidence.
- Psychology can test hypotheses; common sense cannot.
5. EVOLUTION OF PSYCHOLOGY
5.1 Philosophical Roots
- Early ideas about behaviour came from Greek philosophers like Socrates, Plato, Aristotle.
- Indian philosophical traditions also discussed mind and consciousness (Yoga, Buddhism).
- Psychology evolved from philosophy and natural sciences.
5.2 Psychology as a Scientific Discipline
- Wilhelm Wundt established the first psychology laboratory in 1879 at Leipzig, Germany.
- He used introspection to study consciousness.
- This marked the beginning of modern scientific psychology.
5.3 Major Schools of Psychology
- Structuralism – Wundt & Titchener; studied the structure of the mind.
- Functionalism – William James; focused on the functions of behaviour.

- Behaviourism – Watson, Skinner; focused on observable behaviour only.
- Psychoanalysis – Freud; focused on unconscious mind and childhood experiences.
- Humanistic psychology – Maslow, Rogers; emphasised personal growth.
- Cognitive psychology – studied thinking, memory, problem solving.
- Biological psychology – studied brain, neurotransmitters, hormones.
- Evolutionary psychology – behaviour shaped by evolution and survival needs.
- Cultural psychology – behaviour influenced by cultural systems.
5.4 Contemporary Psychology
- Uses multiple perspectives.
- Focuses on applied areas—health, business, education, sports.
- Integrates technologies like neuroimaging, AI, and behavioural analytics.
- Emphasises multicultural and global perspectives.
6. DEVELOPMENT OF PSYCHOLOGY IN INDIA
