摘要
研究采用ERP技术对59名儿童工作记忆水平与事件相关电位进行比较分析,以说明工作记忆发展的神经电生理基础及年龄特征。实验仪器为美国NICOLET公司生产的COMPACT FOUR脑诱发电位仪。结果发现:(1)儿童工作记忆水平与P300各成分潜伏期呈负相关,与P300各成分的振幅呈正相关。(2)儿童P300的各潜伏期随年龄增长而下降,振幅随年龄增长而增大。(3)不同性别儿童P300各成分均无显著性差异。
The equipment Evoked Potential Compact Four was used to investigate the neuroelectrical features and age characteristics of children' s working memory development The results showed that : ( 1 ) There was a negative correlation between the child' s working memory and the latencies of the P300, but there was a positive correlation between the child's working memory and the latencies of the P300. (2)General trend of P300 development of children was that the latency of the ERP dropped with age increased, whereas amplitude went up obviously with age increased. (3)There were no significant differences between two genders on P300
