Purpose The goal of this study was to examine online and off-line sentence processing using Korean language relative clause sentences between children with specific language impairment (SLI) and children with typical development (TD). Method Twenty-four children with TD and 19 children with SLI participated in this study. Children completed online and off-line sentence-processing tasks using relative clause sentences. The response time (RT) data obtained from the online processing task were analyzed at each word position and between adjacent words for items answered both correctly and incorrectly on the off-line comprehension task. A linear mixed-effects model and a generalized linear mixed-effects model were used to analyze the performances on the online/off-line sentence-processing task between the two groups. Results The results revealed that the processing pattern of RTs on the online processing task differed between the two groups, such that the SLI group did not show the predicted RT increase while the TD group did. Also, the SLI group processed each word with comparable or faster reading rates than the TD group. On the off-line comprehension task, the SLI group performed poorly compared to the TD group. Conclusions Processing of syntactically complex sentences differed between the TD and SLI groups, such that the SLI group had lower accuracy on the off-line comprehension task and was less efficient on the online processing task as compared to the TD group. These results mainly support the syntactic deficit account in children with SLI.
目的 本研究的目的是使用韩语关系从句句子，对特定语言障碍（SLI）儿童和发育正常（TD）儿童的在线和离线句子处理进行研究。方法 24名发育正常儿童和19名特定语言障碍儿童参与了本研究。儿童使用关系从句句子完成在线和离线句子处理任务。对于离线理解任务中回答正确和错误的项目，分析从在线处理任务中获得的反应时间（RT）数据在每个单词位置以及相邻单词之间的情况。使用线性混合效应模型和广义线性混合效应模型分析两组在在线/离线句子处理任务上的表现。结果 结果显示，两组在在线处理任务上的反应时间处理模式不同，即SLI组未表现出预测的反应时间增加，而TD组表现出了。此外，SLI组处理每个单词的阅读速度与TD组相当或更快。在离线理解任务上，SLI组的表现比TD组差。结论 TD组和SLI组在句法复杂句子的处理上存在差异，与TD组相比，SLI组在离线理解任务上准确性较低，在在线处理任务上效率较低。这些结果主要支持了特定语言障碍儿童的句法缺陷理论。
