摘要

尽管人们普遍认为人脸识别依赖于整体处理,但发育性前视患者(DPs)的人脸识别缺陷是否可以用整体处理受损来解释,目前还存在争议。过去的研究结果不一,这可能是由于发育性前斜视患者的缺陷具有异质性,而且使用了不同的整体加工测量方法--倒置、部分-整体和复合任务--这些方法之间的关联性较差。本研究旨在进一步了解整体加工在 DP 中的作用。研究人员让一组民主双语症患者和一组神经畸形患者完成了三项测试,分别测量整体面孔加工和非面孔对象(即纳文任务)。在群体水平上,DPs 在纳文任务中表现出:(1)反转和部分整体效应减弱,但并非不存在;(2)复合面孔效应的程度相当;(3)全局优先效应。然而,单例分析表明,DPs 的这些整体加工缺陷具有异质性。

The heterogeneity of holistic processing profiles in developmental prosopagnosia: holistic processing is impaired but not absent.

Although it is generally assumed that face recognition relies on holistic processing, whether face recognition deficits observed in Developmental Prosopagnosics (DPs) can be explained by impaired holistic processing is currently under debate. The mixed findings from past studies could be the consequence of DP's heterogeneous deficit nature and the use of different measures of holistic processing-the inversion, part-whole, and composite tasks-which showed a poor association among each other. The present study aimed to gain further insight into the role of holistic processing in DPs. Groups of DPs and neurotypicals completed three tests measuring holistic face processing and non-face objects (i.e., Navon task). At a group level, DPs showed (1) diminished, but not absent, inversion and part-whole effects, (2) comparable magnitudes of the composite face effect and (3) global precedence effect in the Navon task. However, single-case analyses showed that these holistic processing deficits in DPs are heterogeneous.
