A study is reported which tests the proposition that faces capture the attention of those with autism spectrum disorders less than a typical population. A visual search task based on the Face-in-the-Crowd paradigm was used to examine the attentional allocation of autism spectrum disorder adults for faces. Participants were required to search for discrepant target images from within 9-image arrays. Both participants with autism spectrum disorder and control participants demonstrated speeded identification of faces compared to non-face objects. This indicates that when attention is under conscious control, both autism spectrum disorder and typically developing comparison adults show an attentional bias for faces, which contrasts with previous research which found an absence of an attentional bias for faces in autism spectrum disorder. Theoretical implications of this differentiation are discussed.
本文报告了一项研究，该研究检验了一个命题：与典型人群相比，患有自闭症谱系障碍的人对面孔的注意力捕捉较少。基于“人群中的面孔”范式的视觉搜索任务被用于研究自闭症谱系障碍成年人对面孔的注意力分配。参与者需要从9张图像阵列中搜索不同的目标图像。与非面孔物体相比，自闭症谱系障碍参与者和对照组参与者都表现出对面孔的快速识别。这表明，当注意力处于有意识控制之下时，自闭症谱系障碍成年人和发育正常的对照组成年人都表现出对面孔的注意力偏向，这与之前发现自闭症谱系障碍患者不存在对面孔注意力偏向的研究形成了对比。本文讨论了这种差异的理论意义。
