Abraham Maslow's holistic-dynamic theory proposes a hierarchy of needs that motivates human behavior. It assumes people have an innate potential for psychological growth towards self-actualization. The hierarchy consists of physiological needs, safety needs, love and belongingness needs, esteem needs, and self-actualization needs. Lower needs must be satisfied before higher needs can motivate behavior. Maslow studied self-actualized individuals to identify qualities like embracing personal growth, creativity, and living according to humanistic values rather than deficiency needs. His theory views people as inherently motivated towards fulfillment and psychological health.
