Final answer:
Maslow's hierarchy of needs is a foundational concept in psychology, created by Abraham Maslow to detail the stages of human motivation from basic needs to self-actualization.
Step-by-step explanation:
Abraham Maslow's hierarchy of needs is a theory in psychology. Maslow is well-known for this concept, which is grounded in humanistic psychology. He indicated that basic physiological and safety needs must be met before higher-level needs, like self-actualization, can become motivational forces. The hierarchy of needs begins with fundamental requirements for survival, progresses through social and esteem needs, and culminates in self-actualization, the process of realizing one's full potential. This theory has made significant contributions to psychology, particularly in understanding human motivation and personal development.
