摘要
目的探讨卡片推理与词语结构类比推理对事件相关电位的影响。方法采用Netsta-tion事件相关电位记录和分析系统，测定14名大学生的事件相关电位。结果4卡片推理与类比推理在头皮前部和后部正确反应和错误反应，波幅差异不均衡；150ms300ms时窗下，反应类型和记录点的交互作用显著（F=1．838，P〈0．05）；记录点的主效应显著（F=1．874，P〈0．05）；250ms-500ms时窗下，记录点的主效应显著（F=2．516，P〈0．05）。结论4卡片条件推理与类比推理具有不同的神经机制，大脑左半球和右半球在两种推理中起着不同的作用。
Objective To explore the variability of event-related potentials（ERPs） of different types of reasoning. Methods ERPs of 14 undergraduates were measured using Netstation ERP Recording and Analysis Systems. Results Amplitudes were significantly different between four-card and analogical reason- ing in frontal and posterior part of cortex. ; during time window （150-300） ms, the interaction of reaction type and recording point （F=I. 838,P〈0.05） and the main effect was significant （F=I. 874,P〈0.05）： During the time window（250-500） ms, the main effect was significant（F=2. 516,P〈0.05）. Conclusion Four-card reasoning has different neromechanism from analogical reasoning, left or right hemisphere plays a different role in two reasoning.
