The present study tested the assumption that the momentary level of self-control strength affects the accuracy rates in a sports-related judgment and decision-making task. A total of = 27 participants rated the veracity of 28 video-taped statements of soccer players who were interviewed by a non-visible referee after a critical game-related situation. In half of the videos, the players were lying, and in the other half, they were telling the truth. Participants were tested twice: once with temporarily depleted self-control strength and once with temporarily available self-control strength (order counterbalanced; measurements separated by exactly 7 days). Self-control strength was experimentally manipulated with the Stroop task. In line with two-process models of information processing, we hypothesized that under ego depletion, information is processed in a rather heuristic manner, leading to lower accuracy rates. Contrary to our expectations, the level of temporarily available self-control strength did not have an effect on accuracy rates. Limitations and implications for future research endeavors are discussed.
自我控制力量的瞬间水平会影响与运动相关的判断和决策任务中的准确率。共有27名参与者对28段足球运动员的录像陈述的真实性进行评分，这些陈述是在一场关键的比赛相关情境后由一名看不见的裁判进行采访时做出的。在一半的视频中，球员在说谎，而在另一半视频中，他们在说实话。参与者接受了两次测试：一次是在自我控制力量暂时耗尽的情况下，另一次是在自我控制力量暂时可用的情况下（顺序平衡；测量间隔正好7天）。自我控制力量通过斯特鲁普任务进行实验操纵。根据信息处理的双过程模型，我们假设在自我损耗的情况下，信息以一种相当启发式的方式进行处理，从而导致较低的准确率。与我们的预期相反，暂时可用的自我控制力量水平对准确率没有影响。讨论了本研究的局限性以及对未来研究工作的启示。
