Autism spectrum disorders (ASD) are associated with face perception atypicalities, and atypical experience with faces has been proposed as an underlying explanation. Studying the own‐race advantage (ORA) for face recognition can reveal the effect of experience on face perception in ASD, although the small number of studies in the area present mixed findings. This study probed the ORA in ASD by comparing two cultural groups simultaneously for the first time. Children with ASD in the UK (N = 16) and Japan (N = 26) were compared with age‐ and ability‐matched typically developing (TD) children in the UK (N = 16) and Japan (N = 26). Participants completed a two‐alternative forced‐choice task, whereby they had to recognize a just seen face from a foil which was manipulated in one of four ways (IC: identity change; EE: easy eyes; HE: hard eyes; HM: hard mouth). Face stimuli were Asian and Caucasian, and thus the same stimuli were own and other race depending on the cultural group. The ASD groups in the UK and Japan did not show impaired face recognition abilities, or impairments with recognizing faces depending on manipulations to the eye region, and importantly they showed an ORA. There was considerable heterogeneity in the presence of the ORA in ASD and TD and also across cultures. Children in Japan had higher accuracy than children in the UK, and TD children in Japan did not show an ORA. This cross‐cultural study challenges the view that atypical experiences with faces lead to a reduced/absent ORA in ASD. 相似文献

In this study, we created composite faces using mothers’ faces to examine holistic face processing in infants aged 5–8 months. The composite-face effect occurred only in infants aged 7–8 months, suggesting that infants older than 7 months are able to process familiar faces holistically. 相似文献

人类能够快速提取集合中的统计信息, 形成平均表征。对于平均表征的产生机制, 研究者提出整合集合成员以合成平均刺激, 或计算集合成员特征值的平均值两种观点。以往研究中合成的平均刺激的特征值和计算成员特征值的平均值两种方式的结果相似, 难以区分两种观点。由于多个面孔的吸引力评分的均值与用这些面孔合成的平均面孔的吸引力评分存在差异, 本研究使用经典的平均辨别任务(实验1和2)和吸引力评价任务(实验3和4)为平均表征的产生来源于合成平均刺激的观点提供了支持证据。4个实验分别采用大容量面孔集合和小容量面孔集合探讨平均表征的形成机制, 结果发现大、小集合都形成了平均刺激, 并且平均表征的评定和加工可能更多依赖合成的平均刺激, 而非简单的对成员特征值进行平均; 此外, 集合吸引力出现了高评现象, 但小集合高评现象更少出现, 说明平均刺激的作用受到集合大小的影响。本研究为集合平均表征的形成机制和面孔集合吸引力高评现象的产生机制提供了新证据。 相似文献

人类嗓音作为听觉环境的重要组成部分, 包含了大量副语言信息以帮助识别个体身份, 尤其对于盲人而言, 视觉面孔经验的缺乏使得嗓音信息成为其感知对方个体特征的主要来源。通过结合正常视力者和盲人在嗓音选择性加工和嗓音身份加工方面的研究, 尝试揭示普遍的人类嗓音加工模式以及盲人特异的嗓音加工机制。此外, 与视觉面孔加工相关的梭状回脑区也参与并卷入了两类人群的嗓音加工任务, 以此为基础梳理的视听整合模型和基于去掩蔽效应的跨模态重组假说, 为这两类人群嗓音加工神经基础的差异性提供了相应的解释机制, 未来研究希望可以进一步探究盲人的嗓音加工策略, 以及考察左侧颞上沟/回脑区在嗓音加工中的作用。 相似文献

本研究采用眼动技术,操纵词类型和熟悉性来探讨汉语新词的词汇化程度。结果发现,新词在眼动早期、晚期加工指标上和词汇词没有显著差异;相比低熟悉新词,高熟悉新词在凝视时间、回视时间及总注视时间上加工时间更短。研究表明部分新词已达到与《现代汉语词典》中词汇词词汇化程度的相同水平,新词与词之间没有严格的界限,熟悉性在新词词汇化过程中起到了主要作用。 相似文献

The presence of multiple faces during a crime may provide a naturally-occurring contextual cue to support eyewitness recognition for those faces later. Across two experiments, we sought to investigate mechanisms underlying previously-reported cued recognition effects, and to determine whether such effects extended to encoding conditions involving more than two faces. Participants studied sets of individual faces, pairs of faces, or groups of four faces. At test, participants in the single-face condition were tested only on those individual faces without cues. Participants in the two and four-face conditions were tested using no cues, correct cues (a face previously studied with the target test face), or incorrect cues (a never-before-seen face). In Experiment 2, associative encoding was promoted by a rating task. Neither hit rates nor false-alarm rates were significantly affected by cue type or face encoding condition in Experiment 1, but cuing of any kind (correct or incorrect) in Experiment 2 appeared to provide a protective buffer to reduce false-alarm rates through a less liberal response bias. Results provide some evidence that cued recognition techniques could be useful to reduce false recognition, but only when associative encoding is strong. 相似文献

Face identification is more accurate when people collaborate in social dyads than when they work alone (Dowsett & Burton, 2015, Br. J. Psychol., 106, 433). Identification accuracy is also increased when the responses of two people are averaged for each item to create a ‘non-social’ dyad (White, Burton, Kemp, & Jenkins, 2013, Appl. Cogn. Psychol., 27, 769; White et al., 2015, Proc. R. Soc. B Biol. Sci., 282, 20151292). Does social collaboration add to the benefits of response averaging for face identification? We compared individuals, social dyads, and non-social dyads on an unfamiliar face identity-matching test. We also simulated non-social collaborations for larger groups of people. Individuals and social dyads judged whether face image pairs depicted the same- or different identities, responding on a 5-point certainty scale. Non-social dyads were constructed by averaging the responses of paired individuals. Both social and non-social dyads were more accurate than individuals. There was no advantage for social over non-social dyads. For larger non-social groups, performance peaked at near perfection with a crowd size of eight participants. We tested three computational models of social collaboration and found that social dyad performance was predicted by the decision of the more accurate partner. We conclude that social interaction does not bolster accuracy for unfamiliar face identity matching in dyads beyond what can be achieved by averaging judgements. 相似文献

为了探究内隐面孔再认在记忆形成过程中的认知加工状态,该实验以陌生面孔为刺激,采用事件相关电位(ERP)技术,并结合相继记忆(Dm)范式和迫选再认测验,把学习阶段的面孔分为相继记住、相继启动及相继忘记三类,以相继记住与相继启动的 ERP 差异为外显记忆 Dm 效应,以相继启动与相继忘记的差异为内隐记忆的 Dm效应。结果表明,内隐记忆表现为400~500 ms额中央区负走向的 Dm效应,可能反映了额叶皮层对信息的精加工过程,而外显记忆表现为400 ms开始顶区正走向的Dm效应,可能反映了记忆系统对加工后信息的自动登记过程。由此推测,只有经过额叶加工并被内侧颞叶自动登记的信息,随后才能被有意识地提取出来,而未进入内侧颞叶的信息在随后测验中不可能产生有意识地记忆提取现象,但储存的知觉表征可能触发微弱的记忆痕迹,从而产生内隐面孔记忆。 相似文献
