Final answer:
Abraham Maslow and Carl Rogers are key figures in humanistic psychology, which contrasts with behaviorism's determinism and psychoanalysis's focus on the unconscious by highlighting personal growth, free will, and innate potential for good.
Step-by-step explanation:
Two advocates of humanistic psychology are Abraham Maslow and Carl Rogers. Humanistic psychology differs from behaviorism and psychoanalysis in several key ways. Behaviorism views humans as passive reactors to their environment with behavior determined by genetics and environmental factors, while psychoanalysis focuses on the role of unconscious processes and past conflicts. On the other hand, humanistic psychology emphasizes free will, personal growth, and self-actualization. It suggests that humans have an innate capacity for goodness and self-improvement. Maslow's theory of the hierarchy of needs and Rogers's client-centered therapy are two well-known contributions of humanistic psychology that emphasize these principles.
