The document discusses various theories of motivation including:
1. Maslow's hierarchy of needs theory which proposes humans have physiological, safety, belonging, esteem, and self-actualization needs.
2. McGregor's Theory X and Theory Y which describe authoritarian vs. participative management styles.
3. Herzberg's two-factor theory which distinguishes between job hygiene and motivator factors.
4. McClelland's theory of needs which identifies the needs for achievement, affiliation, and power as key motivators that influence behavior.
