自闭症语言的一个很少被研究的方面是词汇和支撑单个单词或单词类型的概念性知识。在这项描述性研究中，我们调查了7万字会话自闭症语言语料库中的异常词汇使用情况，并检验了自闭症患者概念形成以及词汇异常的证据。特别注意人工制品和时间概念的表达，一些人认为这些概念可能在自闭症中异常发展。几乎没有发现异常使用伪像术语的证据，尽管时间(和空间)表达的错误相对常见。我们讨论了为什么可能会这样，并考虑了几种可能的解释，解释了为什么自闭症的潜在词汇知识不一定反映在词汇使用中。
One aspect of autistic language that has been infrequently researched is vocabulary and the conceptual knowledge underpinning individual words or word types. In this descriptive study we investigate anomalous vocabulary use in a 70,000-word corpus of conversational autistic language and examine evidence that concept formation, and hence vocabulary, is abnormal in autism. Particular attention is paid to the expression of artifact and temporal concepts which some believe may develop abnormally in autism. Little evidence is found of anomalous use of artifact terms, though errors with temporal (and also spatial) expressions are relatively common. We discuss why this may be and consider several potential explanations for why underlying lexical knowledge in autism may not necessarily be reflected in lexical use.
