The document discusses various theories of motivation including: 1. Maslow's hierarchy of needs which identifies physiological, safety, social, esteem, and self-actualization needs. 2. Herzberg's two-factor theory which separates motivators like achievement and responsibility from hygiene factors like salary and job security. 3. Cognitive evaluation theory which explains how extrinsic rewards can reduce intrinsic motivation by decreasing a person's sense of control and changing their perception of a task.
