Data from: Effects of time pressure and time passage on face-matching accuracy

This study investigated the impact of time pressure on matching accuracy with face pairs that combined photographs from student ID cards with high-quality person portraits, and under conditions that provided infrequent identity mismatches. Time pressure was administered via two onscreen displays that observers could use to adjust the amount of time that was allocated to a given trial while completing a block of trials within a required timeframe. Under these conditions, observers matched faces under time pressure that varied from 10 to 2 s (Experiment 1) and 8 to 2 s (Experiment 2). An effect of time pressure was found in each experiment, whereby performance deteriorated under time targets of 4 s. Additionally, a match response bias emerged consistently across blocks, and indicated that separately to time pressure, performance also deteriorated due to time passage. These results therefore indicate that both time passage and pressure exert detrimental effects on face matching.

本研究探究了时间压力对人脸配对（face matching）准确率的影响，实验所用人脸对由学生证照片与高质量个人肖像组合而成，且实验条件中仅存在偶发的身份不匹配样本。本研究通过两种屏幕显示界面施加时间压力，被试可在规定时限内完成一组实验组块试次时，调整分配给单个试次的时长。在此实验设置下，被试在时间压力条件下完成人脸配对任务：实验1的时间限制从10秒逐步降至2秒，实验2则从8秒逐步降至2秒。两项实验均观测到显著的时间压力效应，当时间阈值降至4秒时，被试的任务表现出现明显衰退。此外，所有实验组块中均一致出现匹配反应偏差，这提示：除时间压力外，任务表现还会随时间流逝而出现衰退。综上，本研究结果表明，时间流逝与时间压力均会对人脸配对任务产生负面影响。
