This document discusses several theories of motivation:
- Equity theory proposes that individuals want fair rewards for their contributions relative to peers. Unfair rewards cause distress.
- Expectancy theory suggests motivation depends on how much an outcome is wanted and the likelihood of achieving it through effort.
- Reinforcement theory argues behavior resulting in rewards will be repeated, while punished behavior will not.
- Need achievement theory identifies three needs - achievement, power, and affiliation - that influence behavior and motivation.
