摘　　要：采用事件相关电位(ERP)技术对中文遥远距离联想任务中的问题解决过程进行了研究。结果表明,在800-1600 ms的时间窗口中,顿悟条件(强烈的"啊哈"体验)比非顿悟条件(没有"啊哈"体验)诱发出更负性脑电成分(LNC1),偶极子源分析表明LNC1起源于左侧前额叶皮层(PFC)和前扣带回(ACC),它可能与顿悟问题解决过程中心理定势的打破有关。之后,在1800-2300ms的时间窗口中,相比于非顿悟条件,顿悟条件下观察到了一个波幅更大的晚期负性成分(LNC2),偶极子源分析表明LNC1起源于楔前叶,它可能反映了新异联结的形成过程。The electrophysiological correlates of Chinese compound remote associate problems solving were studied using event-related potentials （ERPs）. Results showed that Insight condition （strong Aha feeling） elicited a more nega- tive ERP deflection （ LNC1 ） than did Non-Insight condition （ no Aha feeling） in the time window of 800 - 1600ms. Dipole source analysis showed that the generators of LNC1 were localized in the left prefrontal cortex （PFC） and the anterior cingulate cortex （ACC）, which might be related Then, a greater slow negative ERP deflection （LNC2） in to break mental sets during insight problem solving. Insight condition as compared to Non-Insight condition was observed in the time window of 1800 - 2300ms. Dipole source analysis showed that the generator of LNC2 was localized in the precuneus, which might be involved in forming novel associations.
