There is considerable debate about whether people with autism spectrum disorder (ASD) are biased toward local information and whether this disrupts their ability to integrate two complex shapes elements into a single figure. Moreover, few have examined the relationship between integration ability and ASD symptom severity. Adolescent/adult males with ASD and age and IQ-matched controls were compared on their performance of a simple silhouette-to-shape matching task and a higher-order shape-integration task. Relative to basic silhouette-to-shape matching, ASD participants were disproportionately slower than controls on shape-integration. Moreover, this relative slowing correlated with increased symptom severity in ASD participants. These findings support the notion that integrating local information is disproportionately more challenging in ASD; this weakness may play a role in ASD symptomatology.
关于自闭症谱系障碍（ASD）患者是否偏向于局部信息，以及这是否会干扰他们将两个复杂形状元素整合为一个单一图形的能力，存在相当多的争论。此外，很少有人研究整合能力与ASD症状严重程度之间的关系。研究人员比较了患有ASD的青少年/成年男性与年龄和智商匹配的对照组在简单轮廓到形状匹配任务和高阶形状整合任务中的表现。相对于基本的轮廓到形状匹配，ASD参与者在形状整合方面比对照组慢得多。此外，这种相对减慢与ASD参与者症状严重程度的增加相关。这些发现支持了这样一种观点，即在ASD中整合局部信息的挑战要大得多；这种弱点可能在ASD症状学中起作用。
