This document discusses Maslow's hierarchy of needs theory of motivation. The theory proposes that people are motivated to fulfill basic needs before moving on to other needs. The hierarchy consists of 5 levels from basic physiological needs like food and water to more advanced needs like esteem and self-actualization. Maslow's theory suggests that lower level needs must be satisfied before higher level needs can motivate behavior. The document provides examples of each level of needs and explains that once a need is met, it no longer motivates individuals to pursue it further.
