摘要
自我控制的资源模型为探讨个体的选择提供了一个全新的视角。已有研究表明,选择能够消耗自我控制资源,引发自我损耗。然而,已有考查选择损耗效应的研究并未对个体较稳定的人格特征进行控制,同时对于选择损耗效应的产生原因的探讨也需要深化。本研究在对被试的特质自我控制水平进行控制的基础上,通过设置并独立操纵选择任务的取舍冲突难度变量和选择的其他难度变量,探索选择损耗效应的产生原因。结果发现:(1)在控制了被试的特质自我控制水平后,完成选择任务的被试随后的Stroop任务成绩显著低于完成评定任务的被试;(2)完成高取舍冲突难度选择的被试随后的Stroop任务成绩显著低于完成低取舍冲突难度选择的被试,而选择的阅读难度对随后的Stroop任务成绩并没有影响,且取舍冲突难度与阅读难度无交互作用存在;(3)为自己做选择组被试随后的Stroop任务成绩显著低于为他人做选择组被试,而选项信息加工难度对随后的Stroop任务成绩并没有影响,且取舍冲突难度与选项信息加工难度无交互作用存在。这表明,选择具备损耗效应,选择损耗效应是由选择的取舍冲突困难导致的。
The strength model of self-control provided a new perspective for discussing people's choices. Studies have found that making choices can deplete self-control resource and lead to ego depletion. But existing research on testing depletion effect did not control subjects' trait self-control, and the causes of depletion effect in study also need to deepen. In this study we will explore the reason of the choice depletion by setting and manipulating the variable of trade-off conflict and other difficulty after controlling subjects' trait self-control. We found that:(1)Subjects' performance of Stroop task after making choices was significant lower than the subjects who made assessment tasks when subjects' trait self-control were controlled;(2)Subjects' performance of Stroop task after making high trade-off conflict was significant lower than the subjects who made low trade-off conflict, reading difficulty of choice has no influence on Stroop task performance, there has no interaction effect of trade-off conflict and reading difficulty;(3)Subjects' performance of Stroop task after choosing for themselves was significant lower than the subjects who choose for others, option information processing difficulty has no influence on Stroop task performance, there has no interaction effect of trade-off conflict and information processing difficulty. These findings provide evidence that making choices have depletion effect and it is trade-off conflict difficulty cause depleting.
