and Behaviorism
Behaviorism, founded by B.F. Skinner, developed out of the idea that all human behavior can be understood as the result of outside forces. Rather than seeking insight in the deep recesses of the mind, observable behavior is the basis for understanding human reactions. Pavlov's famous experiment with dogs is an example of behaviorism.
Humanistic psychology developed in reaction to psychoanalysis and behaviorism, focusing on personal growth, free will and self-actualization, attempting to help individuals to lead happier lives. Abraham Maslow and Carl Rogers are major thinkers in the field of humanist psychology.
