本研究使用眼动追踪来检查2岁和4岁自闭症谱系障碍（ASD）儿童（N = 44）和典型发育（TD）对照组（N = 30）的视觉扫描和面部识别。两个年龄段的TD幼儿扫描和识别面部相似。随着年龄的增长，患有ASD的幼儿越来越远离面部，他们会注意面部的关键特征，并且面部识别受损。识别缺陷与关键面部特征之间的注意力不平衡有关。这项研究表明，ASD患者的面部处理可能会受到早期影响，并随着年龄的增长而进一步受到影响。我们认为，面部处理的缺陷可能会影响自闭症幼儿作为社会伙伴的有效性，因此应该有针对性地进行干预。
This study used eye-tracking to examine visual scanning and recognition of faces by 2- and 4-year-old children with autism spectrum disorder (ASD) (N = 44) and typically developing (TD) controls (N = 30). TD toddlers at both age levels scanned and recognized faces similarly. Toddlers with ASD looked increasingly away from faces with age, atypically attended to key features of faces, and were impaired in face recognition. Deficits in recognition were associated with imbalanced attention between key facial features. This study illustrates that face processing in ASD may be affected early and become further compromised with age. We propose that deficits in face processing likely impact the effectiveness of toddlers with ASD as social partners and thus should be targeted for intervention.
