本研究采用双加工范式探讨了特定语言障碍（SLI）的信息加工局限性。学龄儿童与无SLI被要求回忆言语和空间刺激的情况下，不同的任务，所需的数量和刺激的速度。孩子们回忆起计算机屏幕上显示的X的数字或位置。在某些情况下，他们被要求在完成回忆任务之前说出或指出刺激物的颜色。与正常发育的同龄人相比，SLI儿童在所有条件下对数字和位置的回忆普遍较差。一般发展中国家的儿童获得更大的好处比儿童SLI的条件下，使他们能够分散处理工作在言语和空间反应方式。SLI儿童的一般认知能力和工作记忆中的中央执行功能的限制与反应方式协同作用，限制了信息加工。
A dual-processing paradigm was used to investigate information processing limitations underlying specific language impairment (SLI). School-age children with and without SLI were asked to recall verbal and spatial stimuli in situations that varied the number of tasks that were required and the speed at which stimuli were presented. Children recalled digits or locations of X's that were presented on a computer screen. In some conditions, they were asked to name or point to the color of the stimuli before completing the recall task. In comparison to their typically developing peers, children with SLI had generally poorer recall of digits and locations across all conditions. Typically developing children derived greater benefit than the children with SLI under conditions that enabled them to disperse processing efforts across verbal and spatial response modalities. It appears that limitations In general cognitive capacity and central executive functions in working memory work synergistically with response modality to constrain information processing in children with SLI.
