有特殊语言障碍（SLI）的儿童在包含长距离依赖的句子的产生和感知方面存在困难，但目前尚不清楚这是由于语法知识的障碍还是加工机制的障碍。本研究通过对关系从句的在线自动补空，以及对相同刺激句的离线理解来解决这一问题。正如知识障碍和加工障碍模型所预测的那样，与正常发育的对照组相比，特殊语言障碍儿童在关系从句动词之后缺乏立即填补空白的能力。然而，在对相同刺激句子的离线理解测量上，特殊语言障碍儿童和弱智儿童没有质的差异。这一发现与知识损害是不相容的。我们解释结果表明，特殊语言障碍儿童的加工机制受损（如暂时延迟空白填补），但他们的语法知识没有受损。
Children with Specific Language Impairment (SLI) have been observed to have production and perception difficulties with sentences containing long-distance dependencies, but it is unclear whether this is due to impairment in grammatical knowledge or in processing mechanisms. The current study addressed this issue by examining automatic on-line gap-filling in relative clauses, as well as off-line comprehension of the same stimulus sentences. As predicted by both knowledge impairment and processing impairment models, SLI children showed lack of immediate gap-filling after the relative clause verb, in comparison to a control group of typically developing children. However, on the off-line measure of comprehension of the same stimuli sentences, SLI children and TD children did not differ qualitatively. This finding is incompatible with knowledge impairment. We interpret the results to show that SLI children have impaired processing mechanisms (such as temporally delayed gap-filling) but are not impaired in their grammatical knowledge.
