Humanistic psychology emphasizes the potential for good in all humans and is a reaction against Freudian and behaviorist approaches. Client-centered therapy, developed by Carl Rogers, is based on humanistic principles.
Step-by-step explanation:
Humanistic psychology is a perspective within psychology that emphasizes the potential for good that is innate to all humans. It focuses on personal control, intentionality, and the belief that individuals have a predisposition for "good." Humanistic psychology is a reaction against the Freudian approach, which is pessimistic and deterministic, and the behaviorist approach, which sees humans as passive responders to the environment. Client-centered therapy, developed by Carl Rogers, is a form of therapy based on the humanistic approach that emphasizes empathy, unconditional positive regard, and genuineness in the therapeutic relationship.
