Two preregistered experiments with more than 1,000 participants in total found evidence of an ego depletion effect on attention control. Participants who exercised self-control on a writing task went on to make more errors on Stroop tasks (Experiment 1) and the Attention Network Test (Experiment 2) compared with participants who did not exercise self-control on the initial writing task. The depletion effect on response times was nonsignificant. A mini meta-analysis of the two experiments found a small ( d = 0.20) but significant increase in error rates in the controlled writing condition, thereby providing evidence of poorer attention control under ego depletion. These results, which emerged from preregistered experiments in large samples of participants, represent some of the most rigorous evidence yet of the ego depletion effect.
两项预先注册的实验共涉及 1000 多名参与者，均发现了自我损耗对注意力控制的影响。与初始写作任务中未进行自我控制的参与者相比，在写作任务中进行自我控制的参与者在斯特鲁普任务（实验 1）和注意网络测试（实验 2）中犯的错误更多。在反应时间上，自我损耗的影响并不显著。对这两项实验的小型元分析发现，在受控写作条件下，错误率有较小但显著的增加（d=0.20），从而为自我损耗下注意力控制较差提供了证据。这些结果来自于大型参与者样本的预先注册实验，代表了迄今为止最严格的自我损耗效应证据之一。
