最近的一项研究表明，成年人对因果事件（碰撞）的适应导致随后的事件不太可能被视为因果关系。在这项研究中，我们检查了是否有一个类似的负面适应效应的知觉因果关系发生在儿童，无论是典型的发展和自闭症。先前的研究已经报道了自闭症儿童对面孔身份、面部结构和注视方向的适应能力减弱。为了测试减少适应性编码是否超出了高层次的社会刺激（如面孔），并可能是自闭症感知的一般属性，我们开发了一个儿童友好的范式适应知觉因果关系。我们比较了22名自闭症儿童和22名发育正常的儿童的表现，他们在年龄和能力（智商分数）上都是匹配的。我们发现，在这两个群体中的感知因果关系的显着和同样强大的适应后效。两组在注意力方面也没有差异，这一点在变化检测任务中的反应时间和准确性上表现出来。这些发现表明，自闭症对知觉因果关系的适应在很大程度上类似于典型的发展，而且，适应性编码减弱可能不是知觉层次低水平自闭症的一般特征，这限制了自闭症适应的现有理论。
A recent study showed that adaptation to causal events (collisions) in adults caused subsequent events to be less likely perceived as causal. In this study, we examined if a similar negative adaptation effect for perceptual causality occurs in children, both typically developing and with autism. Previous studies have reported diminished adaptation for face identity, facial configuration and gaze direction in children with autism. To test whether diminished adaptive coding extends beyond high-level social stimuli (such as faces) and could be a general property of autistic perception, we developed a child-friendly paradigm for adaptation of perceptual causality. We compared the performance of 22 children with autism with 22 typically developing children, individually matched on age and ability (IQ scores). We found significant and equally robust adaptation aftereffects for perceptual causality in both groups. There were also no differences between the two groups in their attention, as revealed by reaction times and accuracy in a change-detection task. These findings suggest that adaptation to perceptual causality in autism is largely similar to typical development and, further, that diminished adaptive coding might not be a general characteristic of autism at low levels of the perceptual hierarchy, constraining existing theories of adaptation in autism.
