The document outlines several major schools of thought in psychology including structuralism, functionalism, behaviorism, cognitivism, gestalt psychology, humanism, and psychoanalysis. Structuralism focused on breaking down mental processes into basic components, while functionalism viewed psychology in terms of how the mind helps individuals adapt to their environments. Behaviorism believes all behavior can be explained by environmental causes, and cognitivism studies mental processes like thinking, perceiving, and learning.

Psychoanalysis, founded by Sigmund Freud, focuses on the unconscious mind and how it influences behavior
