Initial exertion of self-control has been suggested to impair subsequent self-regulatory performance. The specific cognitive processes that underlie this ego depletion effect have rarely been examined. Drawing on the dual-process theory of executive control (Engle & Kane, ; Kane & Engle, ), the current meta-analysis revealed that initial self-control exertion impairs participants' capacities of maintaining the task goal but its effect on capacities of resolving response competition is in need of further investigation. Our results are more consistent with recent theoretical views that consider ego depletion as a switch cost and a result arising from reduced motivation to engage in further self-control.
最初的自我控制行为被认为会损害随后的自我调节表现。这种自我损耗效应背后的具体认知过程很少被研究。基于执行控制的双过程理论（恩格尔和凯恩，；凯恩和恩格尔，），当前的元分析表明，最初的自我控制行为会损害参与者维持任务目标的能力，但其对解决反应竞争能力的影响尚需进一步研究。我们的结果与最近的理论观点更为一致，这些观点将自我损耗视为一种转换成本，是由于参与进一步自我控制的动机降低而产生的结果。
