Frith's original notion of 'weak central coherence' suggested that increased local processing in autism spectrum disorder (ASD) resulted from reduced global processing. More recent accounts have emphasised superior local perception and suggested intact global integration. However, tasks often place local and global processing in direct trade-off, making it difficult to determine whether group differences reflect reduced global processing, increased local processing, or both. We present two measures of global integration in which poor performance could not reflect increased local processing. ASD participants were slower to identify fragmented figures and less sensitive to global geometric impossibility than IQ-matched controls. These findings suggest that reduced global integration comprises one important facet of weak central coherence in ASD.
弗里斯最初提出的“弱中央一致性”概念表明，自闭症谱系障碍（ASD）中局部加工的增加是由于全局加工的减少。最近的观点则强调了优越的局部感知，并提出了完整的全局整合。然而，任务通常将局部和全局处理放在直接的权衡中，因此很难确定组间差异是否反映了全局处理的减少、局部处理的增加，或者两者兼而有之。我们提出了两种全局整合的度量方法，在这些方法中，较差的表现不能反映局部加工的增加。与智商匹配的对照组相比，ASD 参与者识别碎片化图形的速度较慢，对全局几何不可能性的敏感性也较低。这些发现表明，全局整合的减少是 ASD 中弱中央一致性的一个重要方面。
