2. Basics of Psychology - Major Psychological Theories: Keys to Understanding Human Behavior and the Mind
Psychology seeks to explore the mysteries of human behavior and mental processes, and over time, various theories have been developed to explain them.
This post provides an overview of major psychological theories and their core ideas.
1. Behaviorism
Key Concept
Behaviorism focuses on observable behaviors, emphasizing how the environment and learning shape actions.
Main Scholars: B.F. Skinner, Ivan Pavlov, John Watson
Famous Experiments
- Pavlov’s Dog Experiment: Explained learning principles through classical conditioning, where dogs salivated at the sound of a bell.
- Skinner’s Box: Demonstrated how rewards and punishments influence behavior.
Applications
Behaviorism is widely applied in education, advertising, and behavior modification programs.
2. Cognitive Psychology
Key Concept
Cognitive psychology examines how humans perceive, process, and use information.
It focuses on questions like, “How do people think and solve problems?”
Main Scholars: Jean Piaget, Ulric Neisser
Key Ideas
- Schemas: Mental frameworks used to organize and interpret information.
- Cognitive Development Stages: The theory that children's thinking evolves in stages as they grow.
Applications
Cognitive psychology informs fields such as educational psychology, artificial intelligence, and memory enhancement.
3. Psychoanalytic Theory
Key Concept
Psychoanalysis posits that human behavior and emotions are deeply influenced by the unconscious mind.
Early childhood experiences play a significant role in shaping personality and behavior.
Main Scholar: Sigmund Freud
Key Ideas
- Id, Ego, and Superego: Three components of personality structure.
- Dream Analysis: Belief that unconscious desires manifest in dreams.
Applications

4. Humanistic Psychology

5. Evolutionary Psychology
Key Concept
Evolutionary psychology explains human behavior and thought through the lens of evolution.
It investigates how certain behaviors were advantageous for survival and reproduction.
Main Influence: Charles Darwin’s theory of evolution.
Key Ideas
- Adaptive Behaviors: Actions that helped humans survive specific environmental challenges.
- Instinctive Reactions: For instance, the fight-or-flight response to perceived threats.
Applications
This perspective is used in social psychology, cultural studies, and biological research.
Conclusion: Diverse Perspectives for Understanding Psychology
Psychology doesn't rely on a single answer to explain human behavior.
Its theories—behavioral, cognitive, psychoanalytic, humanistic, and evolutionary—each offer valuable insights into different facets of the human experience.
By understanding these perspectives, we can gain a deeper appreciation for the complexity of human behavior and apply this knowledge to enrich our lives.
