十个自闭症患者（平均年龄：12;7岁，SD 3.8，范围5;10- 16.0），10例唐氏症患者（12;3岁，SD 3.0，范围7;1- 16，0），以及10名发育正常儿童的对照组（平均年龄：6;3岁，SD 1.6，范围4;0-9;4），匹配的口头心理年龄，进行了测试的延迟匹配任务和排序的偏好任务。第一项任务要求受试者根据所表达的情绪或身份来匹配面孔。与典型的同时匹配过程不同，目标图片被短暂地呈现（750毫秒），并且当样本图片被示出给受试者时是不可见的，从而减少了基于情感面部表情的典型特征的感知的、零碎的、处理策略的可能使用。在第二项任务中，受试者被要求对一个孤立的刺激物的效价进行评级，例如情绪的面部表情或没有人代表的情绪情况。第二个任务的目的是比较自闭症和非自闭症儿童的倾向，判断愉快的面孔使用面部表情的情绪作为一个有意义的指标。结果显示，孤独症个体在面部表情和情绪子任务上的表现都比正常人和唐氏症个体差，但在身份和情绪情境子任务上两组之间没有显著差异。
Ten autistic individuals (mean age: 12;7 years, SD 3.8, range 5;10-16,0), 10 Down individuals (12;3 years, SD 3.0, range 7;1-16,0), and a control group of 10 children with normal development (mean age: 6;3 years, SD 1.6, range 4;0-9;4), matched for verbal mental age, were tested on a delayed-matching task and on a sorting-by-preference task. The first task required subjects to match faces on the basis of the emotion being expressed or on the basis of identity. Different from the typical simultaneous matching procedure the target picture was shortly presented (750 msec) and was not visible when the sample pictures were shown to the subject, thus reducing the possible use of perceptual, piecemeal, processing strategies based on the typical features of the emotional facial expression. In the second task, subjects were required to rate the valence of an isolated stimulus, such as facial expression of emotion or an emotional situation in which no people were represented. The aim of the second task was to compare the autistic and nonautistic children's tendency to judge pleasantness of a face using facial expression of emotion as a meaningful index. Results showed a significantly; worse performance in autistic individuals than in both normal and Down subjects on both facial expression of emotion subtasks, although on the identity and emotional situation subtasks there were no significant differences between groups.
