虽然它已被公认为自闭症患者表现出困难，在他们的面部识别能力，它一直在争论是否这种赤字反映了特定类别的损害的面孔或一般的知觉偏见对当地水平的信息在刺激。在这项研究中，让我们面对它！对大样本的自闭症谱系障碍（ASD）儿童和典型发育（TD）儿童进行了面孔和物体加工技能测试。主要的发现是，当年龄和智商相匹配时，ASD患者在识别方向，表情和特征信息变化的面孔的能力方面选择性受损。在面部辨别任务中，ASD参与者显示出保留的辨别面部嘴部区域的特征和轮廓信息的能力，但在辨别眼睛中的特征和轮廓信息的能力方面受到损害。在物体处理任务中，ASD参与者表现出正常的识别汽车方向变化的能力和上级能力，以区分房屋的特征和外观信息。这些研究结果表明，在ASD的脸处理赤字是不是由于当地的处理偏差，但反映了一个类别特定的损害的脸，其特征在于未能形成视图不变的脸表示和歧视信息的眼睛区域的脸。
Although it has been well established that individuals with autism exhibit difficulties in their face recognition abilities, it has been debated whether this deficit reflects a category-specific impairment of faces or a general perceptual bias toward the local level information in a stimulus. In this study, the Let’s Face It! Skills Battery of developmental face and object processing measures was administered to a large sample of children diagnosed with autism spectrum disorder (ASD) and typical developing (TD) children. The main finding was that when matched for age and IQ, individuals with ASD were selectively impaired in their ability to recognize faces across changes in orientation, expression and featural information. In a face discrimination task, ASD participants showed a preserved ability to discriminate featural and configural information in the mouth region of a face, but were compromised in their ability to discriminate featural and configural information in the eyes. On object processing tasks, ASD participants demonstrated a normal ability to recognize automobiles across changes in orientation and a superior ability to discriminate featural and configural information in houses. These findings indicate that the face processing deficits in ASD are not due to a local processing bias, but reflect a category-specific impairment of faces characterized by a failure to form view-invariant face representations and discriminate information in the eye region of the face.
