What is Psychology? Nature, Scope, Methods and Evolution
UPMSP Intermediate Psychology (Code 133) begins with the definition, scope and historical schools of psychology. Questions test whether you can distinguish psychology from common sense and identify which school or method a statement illustrates.
Definition and scope
Psychology is the scientific study of behaviour and mental processes. Behaviour includes overt actions and covert processes such as thoughts, feelings and motives. It is a science because it is empirical, systematic and replicable. Scope runs from biological processes (neuropsychology) to social interaction (social psychology), plus applied fields such as clinical, educational and industrial psychology.
Schools and milestones
- Structuralism (Wundt, Titchener): introspection to analyse consciousness into elements.
- Functionalism (James): how mental processes help adaptation.
- Gestalt (Wertheimer, Köhler, Koffka): the whole is more than the sum of parts.
- Psychoanalysis (Freud): unconscious conflicts and early experience.
- Behaviourism (Watson, Skinner): observable stimulus-response behaviour.
- Humanistic (Maslow, Rogers): free will, growth and self-actualisation.
- Cognitive: mental processes as information processing.
Wundt's laboratory at Leipzig (1879) is treated as the birth of modern psychology.
Worked example
Statement: 'People remember a categorised list better because the mind actively organises the whole list.' This fits Gestalt/cognitive psychology, which stresses active organisation and wholeness. It does not fit behaviourism (no stimulus-response claim), psychoanalysis (no unconscious conflict) or structuralism (which seeks elements rather than grouping).
Traps
- Psychology is not mind reading or mere common sense; claims need evidence.
- Introspection is a method; structuralism is the school that used it.
- Behaviour in psychology includes mental processes, not only visible actions.
- Wundt, not Freud, established the first psychology laboratory.
