Ever wondered why you suddenly feel nervous before a test, or why a catchy song sticks in your head?
💡 In Simple Words: Psychology is the study of how we think, feel, and act. It looks at why we do what we do, using ideas that scientists have tested over time.
What does "psychology" really mean?
Psychology comes from the Greek words "psyche" (mind) and "logos" (study). So it literally means "the study of the mind". In school, we treat it like a toolbox full of ideas that help us understand behavior.
Key concepts you must know
- Behaviour – any observable action made by a person or animal, like smiling or running.
- Cognition – the mental processes of thinking, remembering, and solving problems.
- Emotion – the feeling part of experience, such as happiness or fear.
- Motivation – the reason or drive behind an action, like hunger making you eat.
- Perception – how we interpret information from our senses, similar to how a camera turns light into pictures.
Major schools of thought
Psychology didn’t start with one idea. Over the years, several “schools” have tried to explain the mind. Think of them as different chefs adding their own spice to the same soup.
Structuralism
Founder: Wilhelm Wundt (often called the father of psychology). Structuralism breaks the mind into basic parts, like a chemist splitting a compound into elements. Researchers used introspection – looking inside your own thoughts – to report sensations.
Functionalism
Founder: William James. Instead of chopping the mind into pieces, functionalism asks what mental processes *do* for us. It’s like asking why a car’s steering wheel exists – to help you steer.
Behaviourism
Founder: John B. Watson, later B.F. Skinner. Behaviourism says we should only study what we can see – behaviour – and ignore the invisible mind. It treats learning like a habit formed by rewards and punishments, similar to training a pet.
Cognitivism
Emerging in the 1950s, cognitivism brought the mind back into the picture. It treats the brain like a computer that processes information, stores it, and retrieves it.
Humanistic psychology
Founders: Carl Rogers and Abraham Maslow. This view focuses on personal growth and self‑actualisation – the idea of becoming the best version of yourself, like a plant reaching for sunlight.
Psychodynamic approach
Founder: Sigmund Freud. He argued that hidden forces in the unconscious (thoughts we’re not aware of) shape our behaviour, much like an iceberg where most of it is below the water.
How psychologists study the mind
Research methods are the tools that let us test ideas. Here are the three most common ones:
- Experiments – manipulate one factor (independent variable) and see how it changes another (dependent variable). It’s like changing the amount of sugar in a recipe to see how sweet the cake gets.
- Observational studies – watch behaviour in natural settings without interfering, similar to a wildlife photographer watching animals.
- Surveys & questionnaires – ask people directly about thoughts or feelings, like a quick poll on favorite movies.
Quick comparison of the main approaches
| Approach | Focus | Method | Key Figure |
|---|---|---|---|
| Structuralism | Basic elements of consciousness | Introspection | Wundt |
| Functionalism | Purpose of mental processes | Observations of behaviour | James |
| Behaviourism | Observable actions | Lab experiments | Watson, Skinner |
| Cognitivism | Information processing | Experiments, computer models | Piaget, Neisser |
| Humanistic | Personal growth | Qualitative interviews | Rogers, Maslow |
| Psychodynamic | Unconscious influences | Case studies, dream analysis | Freud |
Bullet‑point cheat sheet
- Psychology = study of mind and behaviour.
- Behaviour = what we can see; cognition = thinking.
- Major schools: structuralism, functionalism, behaviourism, cognitivism, humanistic, psychodynamic.
- Research tools: experiments, observations, surveys.
- Each school asks a different question: “What is it?”, “What does it do?”, “How does it change?”
📝 Likely Exam Questions
- Define behaviour and give an example. Behaviour is any observable action, such as a student raising a hand in class.
- Differentiate between structuralism and functionalism. Structuralism breaks consciousness into basic sensations using introspection; functionalism looks at the purpose of mental processes and how they help us adapt.
- Explain why behaviourism focuses only on observable actions. Behaviourism argues that only actions can be measured objectively, avoiding speculation about unseen mental states.
- List two research methods used in psychology and briefly describe each. Experiments manipulate variables to see cause‑and‑effect; observational studies watch behaviour in natural settings without interference.
- What does the term ‘unconscious’ mean in the psychodynamic approach? The unconscious refers to thoughts, wishes, and memories that lie outside awareness yet influence behaviour, like an iceberg’s hidden part.
