This document outlines several theories of motivation discussed in an organizational behavior chapter and lecture, including: 1. Maslow's hierarchy of needs describes physiological, safety, social, esteem, and self-actualization needs from lower to higher order. 2. Herzberg's two-factor theory distinguishes between motivators like achievement that improve satisfaction and hygiene factors like salary that prevent dissatisfaction. 3. McGregor's Theory X and Theory Y propose different views of employee motivation and management styles. 4. Goal-setting theory suggests specific, difficult goals improve performance more than easy or vague goals.
