选择损耗自我控制资源:取舍效应还是信息加工难度效应?

Making Choices Deplete Self-control Resource: Trade-off Effect or Information Processing Difficulty Effect?

研究以自我控制的资源模型为理论框架,从选择难度特征的视角出发,通过两项实验考察选择损耗自我控制资源的成因。结果发现,高取舍冲突组被试的stroop任务成绩显著低于低取舍冲突组被试,高、低阅读难度组被试的stroop任务成绩差异不显著;为自己做选择组被试的stroop任务成绩显著低于为他人做选择组被试,完成3选项和4选项任务组被试的stroop任务成绩差异不显著。研究表明,选择损耗效应是由选择的取舍难度而非信息加工难度造成。。

Making choices is a self-control act and all acts of self-control are effortful and draw on a limited resource, resulting in a state that refers to as ego-depletion. The strength model of self-control provided a new perspective for discussing people＇s choices. Studies have found that making choices would deplete self-control resources and lead to ego depletion. However, we poorly understood the reason why making choices has depletion effects. In this study we explored the reason of the choice depletion by setting and manipulating the variables of the trade-off conflict difficulty and the processing difficulty. Because the trait of self-control has robust influence on self-control behavior, we exercised strict control over subjects＇ self- control before the first stage task.
