The document discusses several theories of motivation:
- Maslow's hierarchy of needs proposes that people are motivated to fulfill physiological, safety, belongingness, esteem, and self-actualization needs.
- Herzberg's two-factor theory distinguishes between motivators like achievement that encourage motivation and hygiene factors whose absence can cause dissatisfaction.
- Vroom's expectancy theory holds that motivation depends on expecting that effort will lead to good performance and desired outcomes. Porter and Lawler extended this theory.
- Equity theory suggests people compare their input/outcome ratios to others' and may lose motivation if they perceive unfair treatment.
