The Science of Mind and Behavior
Psychology is the scientific study of mind, brain, and behavior. It explores how we perceive the world, learn, remember, feel emotions, and interact with others.
Major Perspectives in Psychology
- Biological: Focuses on how the brain, neurotransmitters, and genetics influence behavior.
- Cognitive: Examines mental processes like memory, perception, and problem-solving.
- Behavioral: Studies observable actions and the role of the environment.
- Humanistic: Emphasizes free will and self-actualization.
- Psychodynamic: Investigates unconscious motives and conflicts.
Real-World Impact
Understanding psychology helps explain why people react differently to stress, how habits form, and why mental health varies across individuals.
Example Applications
- Clinical psychologists use psychological principles to diagnose and treat mental disorders.
- Teachers apply learning theories to improve classroom motivation.
Examples
