Which psychologist is known for the hierarchy of needs?

Abraham Maslow is recognized for developing the theory of the hierarchy of needs, which is a foundational concept in psychology and human motivation. His model categorizes human needs into a five-tier pyramid, beginning with basic physiological needs at the base and ascending to safety, love and belonging, esteem, and ultimately self-actualization at the top. This framework suggests that individuals must satisfy lower-level needs before they can address higher-level psychological needs, thereby influencing motivation and behavior.

The hierarchy of needs is significant because it highlights the progressive nature of human development and personal growth. Understanding this hierarchy aids psychologists and counselors in identifying where individuals are in their personal needs, which can guide therapeutic approaches or interventions.

Other psychologists mentioned in the choices have made substantial contributions to psychology but are not associated with this particular theory. Sigmund Freud is known primarily for his work in psychoanalysis and theories of psychosexual development. Wilhelm Wundt is often regarded as the father of experimental psychology and focused on structuralism, while John B. Watson is known for founding behaviorism, which emphasizes observable behavior over internal mental states. None of their contributions involve the hierarchy of needs, making Maslow's association with this concept clear and distinct.
