Autistic and non-autistic retarded children who were matched for verbal ability were shown 'standard' pairs of photographs of people who differed in three, two or one of the following respects: sex, age, facial expression of emotion, and the type of hat they were wearing. When given similar photographs to sort, the majority of non-autistic children sorted according to people's facial expressions before they sorted according to type of hat, but most autistic children gave priority to sorting by type of hat, and many neglected the facial expressions altogether. It is suggested that these results reflect autistic children's insensitivity to other people's facial expressions of emotion.
对言语能力相当的自闭症和非自闭症智障儿童展示了“标准”的人物照片对，这些照片中的人物在以下三个、两个或一个方面存在差异：性别、年龄、面部表情以及所戴帽子的类型。当给他们类似的照片进行分类时，大多数非自闭症儿童在根据帽子类型分类之前会先根据人物的面部表情进行分类，但大多数自闭症儿童优先根据帽子类型进行分类，而且许多儿童完全忽略了面部表情。研究表明，这些结果反映出自闭症儿童对他人面部表情情绪不敏感。
