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 whilst completing a block of trials within a required timeframe. Under these conditions, observers matched faces under time pressure that varied from ten to two seconds (Experiment 1) and eight to two seconds (Experiment 2). An effect of time pressure was found in each experiment, whereby performance deteriorated under time targets of 4-seconds. 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.本研究探讨了时间压力对人脸匹配准确率的影响，实验所用人脸对由学生证照片与高质量人像照片组合而成，且实验条件中设置了少量身份不匹配的样本。本研究通过两块屏幕搭建实验界面，被试需在规定时限内完成一组试次，且可在此过程中调整单一试次的分配时长，以此实现时间压力的操控。在此设置下，实验1中被试的人脸匹配任务时间压力区间为10秒至2秒，实验2则为8秒至2秒。两项实验均发现了时间压力的影响效应：当匹配时限降至4秒时，被试的任务表现显著下降。此外，各组试次中均出现了一致的匹配反应偏差，这表明除时间压力外，任务时长的流逝也会单独导致表现下滑。综上，本研究结果表明，时长流逝与时间压力均会对人脸匹配任务产生负面影响。
