尽管有人认为自闭症谱系障碍（ASD）的个体比正常发育的对照组面临更少的整体性，但很少有对这一假设的直接调查。这个问题在使用复合范式之前就已经解决了。结果显示，与对照组相比，asd青少年对面部部位错位的敏感性较低，表明他们的面部加工整体性较差。然而，由于设计的缺陷，无法区分自闭症患者是以部分为基础的方式处理对齐和不对齐的复合材料，还是以整体的方式处理对齐和不对齐的复合材料。我们将患有自闭症的青少年与性别、年龄和智商相匹配的对照组进行了比较，采用了一种更完整的复合范式。结果表明，与对照组一样，患有自闭症谱系障碍的人也会受到面部特征的干扰，而他们被告知要忽略这些特征。然而，如果面部组合物的某些部分不对齐，那么这种干扰在对照组中就会释放出来，而asd患者无论是否对齐，都会受到不相关部分的干扰。本文讨论了两种不同的解释，这两种解释都与asd的感知和/或注意力异常导致对面孔的专业知识水平下降的观点相一致。
Although it has been suggested that individuals with an Autism spectrum disorder (ASD) process faces less holistically than typically developing controls, there are few direct investigations of this hypothesis. This question was addressed before using the composite paradigm. The results had revealed that adolescents with ASDs were less sensitive than controls to the misalignment of face parts and it was concluded their face processing was less holistic. However, because of shortcomings of the design, it was not possible to distinguish whether individuals with Autism processed both aligned and misaligned composites in a part-based fashion, or both in a holistic fashion. We compared adolescents with ASDs to controls matched on sex, age and IQ on a more complete version of the composite paradigm. The results indicate that individuals with ASDs, like controls, experience interference from facial features that they are told to ignore. However, while such interference is released for controls if parts of face composites are misaligned, individuals with ASDs show comparable interference from irrelevant parts regardless of alignment. Two different interpretations are discussed, both compatible with the idea that perceptual and or attentional abnormalities in ASDs result in a diminished level of expertise for faces.
