Abstract: 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 negative 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 to break mental sets during insight problem solving. Then, a greater slow negative ERP deflection (LNC2) in 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.

Key words: insight, compound remote associate problems, event-related potentials (ERPs).

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800-1600ms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。
