Possible peculiarities in face perception in the autistic population were explored through two experiments. Fourteen autistic children (mean age=10 years 1 month) were individually matched to verbal mental age (VMA) and chronological age (CA) subjects. In a first experiment, subjects were to match faces on the basis of either their outer (hair, chin, ears) or their inner (eyes, nose, mouth) aspects. Autistic children performed equally well in both conditions, while VMA-matched children performed better in the outer than the inner part condition. In a second experiment, chimeric faces consisting of the outer part of an individual's face and the inner part of another individual's face were presented to the subjects. None of the groups showed a preference for neither the outer nor the inner part of the face in this condition. Results were discussed in terms of the existence of a local visual processing strategy in this population.
通过两项实验探究了自闭症群体面部感知可能存在的特殊性。14名自闭症儿童（平均年龄 = 10岁1个月）分别与言语心理年龄（VMA）和实际年龄（CA）匹配的受试者进行匹配。在第一个实验中，受试者要根据面部的外部（头发、下巴、耳朵）或内部（眼睛、鼻子、嘴巴）特征来匹配面孔。自闭症儿童在两种情况下表现同样出色，而VMA匹配的儿童在基于外部特征匹配时比基于内部特征匹配时表现更好。在第二个实验中，向受试者呈现由一个人的面部外部和另一个人的面部内部组成的嵌合面孔。在这种情况下，没有一组表现出对面部外部或内部的偏好。根据该群体中存在局部视觉处理策略对结果进行了讨论。
