An overview of the history of psychology, major theories, research methods, and key concepts in the field.
Introduction to Psychology – Study Notes
| Aspect | Description |
|---|---|
| Definition | The scientific study of behavior and mental processes. |
| Goals | 1. Describe – Observe and catalog phenomena. 2. Explain – Identify causes and mechanisms. 3. Predict – Anticipate future behavior or experience. 4. Control/Influence – Apply knowledge to improve wellbeing. |
| Scope | Covers everything from neural activity to social interactions, across the lifespan and across cultures. |
| Era / Figure | Key Contributions | Influence on Modern Psychology |
|---|---|---|
| Wilhelm Wundt (1879) | Established the first laboratory of experimental psychology in Leipzig. | Birth of psychology as an independent scientific discipline; emphasis on introspection and controlled experiments. |
| William James (1890) | The Principles of Psychology; functionalism. | Focus on how mental processes help individuals adapt to environments. |
| Sigmund Freud (late 1800s‑1930s) | Psychoanalysis, unconscious mind, psychosexual stages. | Introduced depth‑psychology, therapeutic techniques, and the idea that early experiences shape later behavior. |
| John B. Watson (1913) | Behaviorism manifesto. | Shift to observable behavior, measurable outcomes, and learning principles. |
| B.F. Skinner (1930s‑1970s) | Operant conditioning, reinforcement schedules. | Applied behavior analysis, behavior modification. |
| Cognitive Revolution (1950s‑1960s) | George Miller, Ulric Neisser, information‑processing models. | Re‑integration of mental processes (memory, perception, problem‑solving) into scientific study. |
| Humanistic Movement (1950s‑1970s) | Carl Rogers, Abraham Maslow. | Emphasis on self‑actualization, client‑centered therapy, positive aspects of human nature. |
| Biopsychology & Neuroscience (late 20th c.) | Advances in brain imaging, neurochemistry. | Direct links between brain structures, neurotransmitters, and behavior. |
| Sub‑field | Core Focus | Typical Methods |
|---|---|---|
| Biological (Neuro) Psychology | Brain, nervous system, genetics, hormones. | fMRI, EEG, lesion studies, pharmacology. |
| Cognitive Psychology | Perception, memory, language, decision‑making. | Laboratory experiments, reaction‑time tasks, computer modeling. |
| Developmental Psychology | Psychological change from infancy to old age. | Longitudinal & cross‑sectional studies, observational protocols. |
| Social Psychology | How people think, feel, and act in groups. | Surveys, field experiments, social priming. |
| Clinical & Counseling Psychology | Assessment & treatment of mental disorders. | Psychotherapy, diagnostic interviews, outcome research. |
| Industrial‑Organizational (I‑O) Psychology | Workplace behavior, employee selection, ergonomics. | Job analyses, psychometrics, field interventions. |
| Educational Psychology | Learning processes, instructional design. | Classroom experiments, standardized testing. |
| Health Psychology | Interaction of psychological factors with health/illness. | Stress‑response studies, health‑behavior interventions. |
| Method | Description | Strengths | Limitations |
|---|---|---|---|
| Experimental | Manipulate independent variable(s) & measure effect on dependent |
