The impact of choice of rewards and feedback on task performance
通过实验室实验（149人）发现，奖励选择及其与反馈的交互作用能提升任务绩效，但选择本身不影响唤醒水平；自我决定理论可解释这一结果。
Abstract A laboratory experiment ( N = 149) tested two hypotheses: that choice of reward will have a positive impact on task performance and that choice would lead to arousal, as measured by reaction speed. The role that feedback information concerning whether subjects were being rewarded for performance on a prior task was also examined. The results revealed that choice and choice interacting with feedback were related to performance, but the choice had no impact on arousal. Self‐determination theory may be used to help interpret these findings. The choice and feedback are non‐controlling and informational to recipients which may increase perceptions of competence and self‐initiative with an accompanying increase in intrinsic motivation to perform well on the task. These theoretical implications and some questions for future research and practical applications are discussed.
