Typically developing (TD) preschoolers and age-matched preschoolers with specific language impairment (SLI) received event-related potentials (ERPs) to four monosyllabic speech sounds prior to treatment and, in the SLI group, after 6 months of grammatical treatment. Before treatment, the TD group processed speech sounds faster than the SLI group. The SLI group increased the speed of their speech processing after treatment. Posttreatment speed of speech processing predicted later impairment in comprehending phrase elaboration in the SLI group. During the treatment phase, change in speed of speech processing predicted growth rate of grammar in the SLI group.
典型发育(TD)的学龄前儿童和年龄匹配的患有特定语言障碍(SLI)的学龄前儿童在治疗前接受了针对四个单音节语音的事件相关电位(ERP)测试,并且在SLI组中,在进行了6个月的语法治疗后再次接受测试。治疗前,TD组处理语音的速度比SLI组快。SLI组在治疗后提高了其语音处理速度。治疗后语音处理速度可预测SLI组后期在理解短语细化方面的损伤情况。在治疗阶段,语音处理速度的变化可预测SLI组语法的增长速度。
