自闭症患者在视觉空间功能方面表现出各种增强能力的迹象。首先，长期以来，他们在嵌入式图形和块设计测试方面优于比较参与者。其次，一些证据表明，处理全球功能的影响，不适当的处理的组成部分的刺激。第三，他们比比较参与者更准确地判断一个倾斜的圆圈的形状在环境中的视觉线索被消除。这表明他们对形状的感知受先验知识的影响较小。第四，它们在视觉阵列中快速搜索特征和连接目标。然而，与早期的报道相反，它们很容易出现视觉错觉。此外，他们确实显示出利用先验知识的证据时，配对的颜色与彩色的目标。因此，我们得出结论，有一些独特的自闭症视觉空间功能，但不一定是以“弱中央一致性”假设所预测的方式。版权所有（C）2004约翰威利父子有限公司。
Individuals with autism show various signs of heightened abilities in visuo-spatial functioning. First, it is long-established that they excel on embedded figures and block design tests relative to comparison participants. Second, some evidence suggests that processing global features is affected by inappropriate processing of the constituent elements of a stimulus. Third, they are more accurate than comparison participants in judging the shape of a slanted circle in a context in which ambient visual cues are eliminated. This suggests that their perception of the shape is less influenced by prior knowledge. Fourth, they are fast at searching for feature and conjunctive targets in a visual array. Contrary to earlier reports, however, they are susceptible to visual illusions. Also, they do show evidence of utilising prior knowledge when pairing a colour with an atypically coloured target. Accordingly, we conclude that there is something distinctive about autistic visuo-spatial functioning, but not necessarily in ways that are predicted by the 'weak central coherence' hypothesis.
