The study was designed to assess the speed and efficiency of visuospatial attentional orienting and the speed of visual processing and motor response in school-age children diagnosed with specific language impairment (SLI). Fifteen participants with SLI (7-15 years old) and their gender- and age-matched normally developing peers performed two formats of a simple visual discrimination task, one requiring the use of attentional orienting for accurate performance, and the other not requiring shifts of attention. The SLI group was characterized by (a) slower visual processing, and (b) slower motor response, but (c) similar attentional orienting speed, relative to the control group. The results are discussed in relation to the 'generalized slowing hypothesis' in SLI and the neural underpinning of visuospatial attentional orienting and SLI.
该研究旨在评估被诊断为特定语言障碍（SLI）的学龄儿童的视觉空间注意定向速度和效率、视觉处理速度以及运动反应速度。15名患有SLI的参与者（7至15岁）及其性别和年龄匹配的正常发育同龄人进行了两种形式的简单视觉辨别任务，一种需要使用注意定向来准确完成任务，另一种则不需要注意力转移。与对照组相比，SLI组的特点是：（a）视觉处理速度较慢，（b）运动反应较慢，但（c）注意定向速度相似。本文将结合SLI中的“普遍减速假说”以及视觉空间注意定向和SLI的神经基础对研究结果进行讨论。
