超级识别器(SR)是在处理面部身份方面表现出自然优势的人。尽管SR研究有所增加,其特殊能力的潜在机制尚不清楚.这里,我们调查了SR的面部识别处理增强是否可以归因于缺乏顺序效应,比如串行依赖。在串行依赖中,对刺激特征的感知被同化为先前试验中提出的刺激。视觉感知中的这种恒定误差已被提出作为在日常生活中促进感知稳定性的机制。我们假设SR中不存在这种恒定的错误源可以解释它们的出色处理-可能以域通用的方式进行。我们测试了通过最近提出的诊断框架(Ramon,2021年)和年龄匹配的对照(n=20),进行了两个实验,以探测面部和形状域中的串行依赖性。在每个实验中,观察者被呈现随机变形的面部身份或形状,并被要求调整面部身份或形状以匹配他们看到的刺激。我们发现控件和SR都存在序列依赖性,各组的大小没有差异。有趣的是,我们发现序列依赖对SR性能的影响大于对控件的影响。一起来看,我们的结果表明,增强SRs中的人脸身份处理技能不能归因于缺乏序列依赖。相反,串行依赖,我们视觉系统中的一个有益的嵌套错误,实际上可以进一步稳定SR的感知,从而增强其视觉处理能力。
Super recognizers (SRs) are people that exhibit a naturally occurring superiority for processing facial identity. Despite the increase of SR research, the mechanisms underlying their exceptional abilities remain unclear. Here, we investigated whether the enhanced facial identity processing of SRs could be attributed to the lack of sequential effects, such as serial dependence. In serial dependence, perception of stimulus features is assimilated toward stimuli presented in previous trials. This constant error in visual perception has been proposed as a mechanism that promotes perceptual stability in everyday life. We hypothesized that an absence of this constant source of error in SRs could account for their superior processing-potentially in a domain-general fashion. We tested SRs (n = 17) identified via a recently proposed diagnostic framework (Ramon, 2021) and age-matched controls (n = 20) with two experiments probing serial dependence in the face and shape domains. In each experiment, observers were presented with randomly morphed face identities or shapes and were asked to adjust a face\'s identity or a shape to match the stimulus they saw. We found serial dependence in controls and SRs alike, with no difference in its magnitude across groups. Interestingly, we found that serial dependence impacted the performance of SRs more than that of controls. Taken together, our results show that enhanced face identity processing skills in SRs cannot be attributed to the lack of serial dependence. Rather, serial dependence, a beneficial nested error in our visual system, may in fact further stabilize the perception of SRs and thus enhance their visual processing proficiency.
