This study investigated whether vocabulary delays in toddlers with autism spectrum disorders (ASD) can be explained by a cognitive style that prioritizes processing of detailed, local features of input over global contextual integration-as claimed by the weak central coherence (WCC) theory. Thirty toddlers with ASD and 30 younger, cognition-matched typical controls participated in a looking-while-listening task that assessed whether perceptual or semantic similarities among named images disrupted word recognition relative to a neutral condition. Overlap of perceptual features invited local processing whereas semantic overlap invited global processing. With the possible exception of a subset of toddlers who had very low vocabulary skills, these results provide no evidence that WCC is characteristic of lexical processing in toddlers with ASD.
本研究调查了自闭症谱系障碍（ASD）幼儿的词汇延迟是否可以用一种认知风格来解释，这种认知风格优先处理输入的详细局部特征而非全局情境整合——这是弱中央连贯性（WCC）理论所主张的。30名患有ASD的幼儿和30名年龄较小、认知匹配的典型对照组幼儿参与了一项边听边看任务，该任务评估相对于中性条件，命名图像之间的感知或语义相似性是否会干扰单词识别。感知特征的重叠引发局部处理，而语义重叠引发全局处理。除了一小部分词汇技能非常低的幼儿外，这些结果没有提供证据表明WCC是患有ASD的幼儿词汇处理的特征。
