Abstract

Previous research on the beneficial effect of motion has postulated that learning a face in motion provides additional cues to recognition. Surprisingly, however, few studies have examined the beneficial effect of motion in an incidental learning task and developmental prosopagnosia (DP) even though such studies could provide more valuable information about everyday face recognition compared to the perception of static faces. In the current study, 18 young adults (Experiment 1) and five DPs and 10 age-matched controls (Experiment 2) participated in an incidental learning task during which both static and elastically moving unfamiliar faces were sequentially presented and were to be recognized in a delayed visual search task during which the faces could either keep their original presentation or switch (from static to elastically moving or vice versa). In Experiment 1, performance in the elastic-elastic condition reached a significant improvement relative to the elastic-static and static-elastic condition, however, no significant difference could be detected relative to the static-static condition. Except for higher scores in the elastic-elastic compared to the static-elastic condition in the age-matched group, no other significant differences were detected between conditions for both the DPs and the age-matched controls. The current study could not provide compelling evidence for a general beneficial effect of motion. Age-matched controls performed generally worse than DPs, which may potentially be explained by their higher rates of false alarms. Factors that could have influenced the results are discussed.

摘要

先前关于运动有益效果的研究推测,在运动中学习面孔能为识别提供额外线索。然而,令人惊讶的是,很少有研究考察运动在附带学习任务和发展性面孔失认症(DP)中的有益效果,尽管与静态面孔感知相比,此类研究能为日常面孔识别提供更有价值的信息。在本研究中,18名年轻成年人(实验1)以及5名发展性面孔失认症患者和10名年龄匹配的对照组(实验2)参与了一项附带学习任务,在此过程中,静态和弹性运动的陌生面孔被依次呈现,并在延迟视觉搜索任务中进行识别,在此任务中,面孔可以保持其原始呈现方式或切换(从静态到弹性运动或反之亦然)。在实验1中,相对于弹性 - 静态和静态 - 弹性条件,弹性 - 弹性条件下的表现有显著改善,然而,相对于静态 - 静态条件,未检测到显著差异。除了年龄匹配组中弹性 - 弹性条件下的得分高于静态 - 弹性条件外,发展性面孔失认症患者和年龄匹配的对照组在各条件之间均未检测到其他显著差异。本研究无法为运动的普遍有益效果提供令人信服的证据。年龄匹配的对照组总体表现比发展性面孔失认症患者差,这可能是由于他们较高的误报率所致。文中讨论了可能影响结果的因素。
