Purpose This study examined whether college students with developmental language disorder (DLD) showed similar sensitivity to verb bias information during real-time sentence processing as typically developing (TD) peers. Method Seventeen college students with DLD and 16 TD college students participated in a mouse-tracking experiment that utilized the visual world paradigm to examine real-time sentence processing. In experimental trials, participants chose 1 of 2 pictured interpretations of a sentence. Measures of interest were the choice of interpretation and the amount of competition from the unchosen picture as measured by mouse curvature. Results Choice of interpretation and mouse movements by college students with DLD suggested less sensitivity to verb bias information than their TD peers. Conclusion College students with DLD showed less evidence of sensitivity to verb bias information than their TD peers in this task. Their performance may reflect the use of compensatory processing strategies and may be related to poor comprehension abilities often observed in this population.
目的 本研究考察了患有发育性语言障碍（DLD）的大学生在实时句子处理过程中对动词偏向信息的敏感度是否与发育正常（TD）的同龄人相似。方法 17名患有DLD的大学生和16名发育正常的大学生参与了一项鼠标追踪实验，该实验利用视觉世界范式来考察实时句子处理。在实验试验中，参与者从句子的两种图片解释中选择一种。感兴趣的测量指标是解释的选择以及由鼠标曲率测量的来自未选择图片的竞争量。结果 患有DLD的大学生对解释的选择和鼠标移动表明，他们对动词偏向信息的敏感度低于发育正常的同龄人。结论 在这项任务中，患有DLD的大学生对动词偏向信息敏感度的证据少于发育正常的同龄人。他们的表现可能反映了补偿性加工策略的使用，并且可能与该群体中经常观察到的较差的理解能力有关。
