在5岁的语言障碍儿童（LI）和年龄和视觉运动整合技能相匹配的同龄人中，研究了新的图形运动符号的获得和巩固到长期记忆中的情况。孩子们练习制作一个新的符号，并在练习后24小时和两周进行测试。表现速度的差异出现在各组之间：LI的儿童表现出较晚的发病快速学习的实践阶段，只有对照组表现出延迟，巩固，收益24小时后培训。在训练后两周，LI儿童改善，缩小了表现速度上的差距。速度-准确性权衡是LI速度改进的特征。这些结果表明，非典型和延迟收购与LI儿童，并支持这一观点，即缺乏技能收购LI超越语言系统。(C)2011爱思唯尔有限公司保留所有权利。
The acquisition and consolidation of a new grapho-motor symbol into long-term memory was studied in 5-year-old children with language impairment (LI) and peers matched for age and visual-motor integration skills. The children practiced the production of a new symbol and were tested 24 h and two weeks post-practice day. Differences in performance speed emerged between the groups: children with LI showed a later onset of rapid learning in the practice phase, and only the comparison group exhibited delayed, consolidation, gains 24 h post-training. At two weeks post-training, children with LI improved, closing the gap in performance speed. Speed-accuracy trade-off was characteristic of speed improvements in LI. These results indicate atypical and delayed acquisition in children with LI, and support the view that deficient skill acquisition in LI goes beyond the language system. (C) 2011 Elsevier Ltd.
