本研究旨在探讨特殊语言障碍幼儿（4-6岁）的接受性语言技能。具体来说，作者研究了他们快速映射对象和动作的语义特征的能力，并将其与具有正常发展语言（NL）的年龄匹配的同龄人的表现进行了比较。孩子们完成了一项电脑任务，在此期间，他们接触到新奇的物体和动作与新奇的名称。然后，孩子们被问到关于这些新奇物体和动作的语义特征的问题。总体而言，关于动作的问题对儿童来说比物体更难。SLI的儿童能够识别的语义特征比NL的同龄人少。他们在词汇标签识别任务中的表现也不如同龄人。这些结果支持了这样一种观点，即SLI儿童在接受性词汇方面有更广泛的困难，而不仅仅是获得标签的能力降低。
This study examined the receptive language skills of young children (4-6 years old) with specific language impairment (SLI). Specifically, the authors looked at their ability to fast-map semantic features of objects and actions and compared it to the performance of age-matched peers with normally developing language (NL). Children completed a computer task during which they were exposed to novel objects and actions with novel names. The children then were asked questions about the semantic features of these novel objects and actions. Overall, the questions about actions were more difficult for children than objects. The children with SLI were able to recognize fewer semantic features than were their peers with NL. They also performed poorly relative to their peers on a lexical label recognition task. These results lend support to the idea that children with SLI have broader difficulties with receptive vocabulary than simply a reduced ability to acquire labels.
