This document discusses motivational theories including Vroom's Expectancy Theory, Porter-Lawler Theory, and intrinsic and extrinsic rewards. It explains that according to expectancy theory, motivation to complete a task is affected by the expected reward. Porter-Lawler theory built upon this by introducing intrinsic rewards like satisfaction and extrinsic rewards like bonuses. It also claims expectancy theory oversimplifies by assuming increased rewards always motivate more work, when employees must value the reward. In conclusion, the document analyzes motivational theories and how expected rewards influence employee motivation.
