An Examination of the Relationships Among Monetary Incentives, Goal Level, Goal Commitment, and Performance
通过实验检验了激励类型、激励水平和目标水平对效价、目标承诺和绩效的影响，发现效价及其斜率中介了激励与目标承诺的关系，且三者交互影响绩效。
This study tested the effects of incentive type, incentive level, and goal level on valence, goal commitment, and performance. Subjects (N=251) worked on a class scheduling task under either piece-rate, hourly, goal attainment bonus, or no-pay conditions, under either high or low amounts of money, and were assigned either easy, moderate, or difficult goals (a 4X2X3 design). Results demonstrated that both the level of valence and valence slope mediated the relationship between incentives and goal commitment. Incentive type, incentive level, and goal level interacted in determining performance, and these effects were not completely mediated by goal commitment.
