The attention control video has been frequently applied to test the ego depletion effect. However, its validity has never been tested, a shortcoming we address in this preregistered study. In the first task, self-control strength was temporarily depleted in the depletion condition (n = 56) but remained intact in the control condition (n = 56). The attention control video served as the secondary task, and we assumed that the depletion condition would perform significantly worse compared to the control condition. Attention regulation was measured with an eye-tracking device. The results revealed that the gaze behavior in the two conditions differed statistically significantly; however, the actual difference was small, indicating that the attention control video may not be an optimal measure of self-control.
注意力控制视频经常被用于测试自我损耗效应。然而，其有效性从未得到过检验，这是我们在这项预先注册的研究中要解决的一个缺点。在第一个任务中，在损耗条件下（n=56）暂时耗尽自我控制强度，但在控制条件下（n=56）保持完整。注意力控制视频作为次要任务，我们假设损耗条件下的表现会明显逊于控制条件。注意力调节通过眼动追踪装置进行测量。结果表明，两种条件下的注视行为存在显著的统计学差异；然而，实际差异很小，表明注意力控制视频可能不是自我控制的最佳衡量标准。
