The authors investigated the impact of video speed on judging the duration of sport performance. In three experiments, they investigated whether the speed of video presentation (slow motion vs. real time) has an influence on the accuracy of time estimation of sporting activities (n1 = 103; n2 = 100; n3 = 106). In all three studies, the time estimation was more accurate in real time than in slow motion, in which time was overestimated. In two studies, the authors initially investigated whether actions in slow motion are perceived to last longer because the distance they cycled or ran is perceived to be longer (n4 = 92; n5 = 106). The results support the hypothesis that the duration of sporting activities is estimated more accurately when they are presented in real time than in slow motion. Sporting officials' judgments that require accurate time estimation may thus be biased when based on slow-motion displays.
作者研究了视频速度对判断体育表现持续时间的影响。在三个实验中，他们研究了视频呈现速度（慢动作与实时）是否会影响对体育活动时间估计的准确性（n1=103;n2=100;n3=106）。在所有三个研究中，实时的时间估计比慢动作更准确，在慢动作中时间被高估了。在两项研究中，作者最初研究了慢动作中的动作是否因为它们所经过的距离被认为更长而被感知为持续时间更长（n4=92;n5=106）。结果支持了这样的假设，即当体育活动以实时呈现时，它们的持续时间估计更准确。因此，当基于慢动作显示时，体育官员的需要准确时间估计的判断可能会产生偏差。
