摘要
目的 探讨心理旋转与事件相关电位特异波P300波幅改变的关系。 资料来源与选择 国内外该领域的研究论文和综述。 资料引用 引用国内外学术刊物上发表的论文及综述。 资料综合 主要是3个方面:①心理旋转和P300波幅改变之间的功能关系;②心理旋转和P300波幅改变之间的时间关系;③处理双重任务时心理旋转的事件相关电位研究。并对该领域的研究进行了展望。 结论 随着旋转角度从0°到180°增加,事件相关电位产生的特异波P300的波幅向负向漂移;推后心理旋转过程,事件相关电位P300波幅的改变将被推后。
Objective To discuss the relationship between the mental rotation and the amplitude modulation of P 300 . Literature resource and selection Research papers and reviews in this field. Literature quotation Seventeen published papers and reviews were cited. Literature synthesis It was summarized in 3 aspects: ①The functional relation between mental rotation and amplitude modulation of P 300 ; ②The time relation between mental rotation and amplitude modulation of P 300 ; ③Studies on ERP and mental rotation while performing dual task. The prospect of further research in this field was also put forward. Conclusion Along with the increase of the angular displacement from upright (from 0°to 180°),the negativity of the P 300 is plotted up. Postponing the process of mental rotation should also postpone onset of the amplitude modulation.
