The document discusses several theories of motivation:
1. Maslow's hierarchy of needs proposes that people are motivated to fulfill basic physiological needs before moving on to more advanced needs for safety, belonging, esteem and self-actualization.
2. Herzberg's two-factor theory distinguishes between motivators like achievement that improve job satisfaction and hygiene factors like salary that prevent dissatisfaction.
3. Vroom's expectancy theory states that motivation depends on the expectation that effort will lead to performance and performance to rewards that the individual values.
4. Goal setting theory suggests that specific, challenging goals lead to higher performance than vague or easy goals.
