| 摘 要： | 采用事件相关电位(ERP)方法,以阿拉伯数字的简单心算为任务,考察数学学习困难儿童(MD)的数字距离效应。行为数据的结果表明:MD组没有出现数字距离效应,对照组儿童出现了数字距离效应。事件相关电位数据显示:与对照组相比,MD组N270的潜伏期更长;两组被试在N270的波幅和潜伏期上都没有表现出数字距离效应。研究结果表明:MD儿童对数量信息的空间表征存在缺陷。

| Abstract: | Using event-related potential(ERP) in simple mental calculation tasks of Arabic numerals,this study investigated the numeral distance effect in children with mathematical learning difficulties.The data of behavioral data indicated that the MD group did not display the numeral distance effect,whereas the control group showed numeral distance effect.Event-related brain potential data showed that compared with the control group,the latency of N270 in MD was much longer.Both groups did not show numeral distance... |
