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 and exert detrimental effects on face matching.
本研究调查了时间压力对将学生证照片与高质量人物肖像相结合的面部配对匹配准确性的影响，以及在身份不匹配情况较少的条件下的影响。时间压力通过两个屏幕显示来施加，观察者在规定的时间范围内完成一组试验时，可以使用这两个屏幕显示来调整分配给给定试验的时间量。在这些条件下，观察者在时间压力下进行面部匹配，时间范围从10秒到2秒（实验1）和8秒到2秒（实验2）。在每个实验中都发现了时间压力的影响，即在4秒的时间目标下，表现会变差。此外，在各个组块中一致出现了匹配反应偏差，这表明除了时间压力外，随着时间的推移，表现也会变差。因此，这些结果表明， 和 都会对面部匹配产生不利影响。 （注：原文中两个“和”的英文未给出，无法准确完整翻译）
