A simultaneous face discrimination learning task was given to 15 autistic children and 14 normal controls. Face stimuli were presented in the form of schematic line drawing. After attaining discrimination, their responses to facial components, namely, color, expression and orientation (upright or inverted), were tested. The autistic group more frequently responded incorrectly to orientation than to the other two components. Moreover, the response latencies to all the three components were shorter in the autistic group than in the normal group. Using the same experimental procedure, a figure discrimination learning task was given to other groups of autistic and normal children. The results indicated no significant differences between the autistic and normal groups in either the rate of correct responses or the latency to figure components. These results were interpreted to suggest that the autistic children recognized face stimuli only in terms of component properties.
对15名自闭症儿童和14名正常对照组儿童进行了一项同时进行的面部辨别学习任务。面部刺激以示意性线条图的形式呈现。在达到辨别能力后，测试他们对面部组成部分的反应，即颜色、表情和方向（正立或倒立）。自闭症组对方向的错误反应比其他两个组成部分更频繁。此外，自闭症组对所有三个组成部分的反应潜伏期都比正常组短。使用相同的实验程序，对其他自闭症和正常儿童组进行了图形辨别学习任务。结果表明，自闭症组和正常组在正确反应率或对图形组成部分的潜伏期方面均无显著差异。这些结果被解释为表明自闭症儿童仅根据组成部分的属性来识别面部刺激。
