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 investigate the relationship between the change of the amplitude of P300 and event-related potentials (P300). Sources and selection of research papers and reviews in this field at home and abroad. References Citing papers and reviews published in academic journals at home and abroad. Data synthesis is mainly three aspects: ① psychological rotation and P300 amplitude changes between the functional relationship; ② psychological rotation and P300 amplitude changes between the time; ③ dual-task psychological rotation of the event-related potential study. And the research in this field is prospected. CONCLUSIONS As the rotation angle increases from 0 ° to 180 °, the amplitude of the P300 wave generated by the event-related potential shifts negatively. When the psychological rotation is delayed, the change of the amplitude of the event-related potential P300 is pushed back.
