眼球追踪研究表明，自闭症谱系障碍（ASC）患者在观看社交场景时，眼球固定时间减少的观点得到了不同程度的支持。我们提出的证据表明，这些混合的结果是由于一个单独的条件-述情障碍-经常与ASC合并症。我们发现，在患有ASC的成年人中，自闭症症状的严重程度与观看视频片段时对面部的注意力呈负相关。然而，只有述情障碍的程度，而不是自闭症症状的严重程度，预测眼睛注视。除了潜在地解决该领域相互矛盾的证据外，这些发现还表明，患有ASC和述情障碍的个体可能形成ASC个体的一个亚群，除了ASC特征的社交障碍外，还存在情感障碍。
Eye-tracking studies have demonstrated mixed support for reduced eye fixation when looking at social scenes in individuals with Autism Spectrum Conditions (ASC). We present evidence that these mixed findings are due to a separate condition-alexithymia-that is frequently comorbid with ASC. We find that in adults with ASC, autism symptom severity correlated negatively with attention to faces when watching video clips. However, only the degree of alexithymia, and not autism symptom severity, predicted eye fixation. As well as potentially resolving the contradictory evidence in this area, these findings suggest that individuals with ASC and alexithymia may form a sub-group of individuals with ASC, with emotional impairments in addition to the social impairments characteristic of ASC.
