Abstract

This study investigates neural mechanisms of divergent and convergent thinking in the verbal knowledge domain while taking into account activation related to working memory (WM). Divergent thinking was assessed using the Alternate Uses Task (AUT) and convergent thinking using the Compound Remote Associates task (RAT). We analyzed upper alpha band (10–12 Hz) oscillatory activity, in which we accounted for the temporal dynamics of both thinking processes by investigating three different time points during each trial for both tasks. We subtracted WM-related oscillatory activity measured by a serial recall task within the same knowledge domain and by using highly similar stimulus material as in both divergent and convergent thinking tasks. Our results show a strong upper alpha synchronization during divergent relative to convergent thinking, most pronounced at fronto-parietal electrodes. Moreover, we observed highest synchronization towards the middle (in contrast to the beginning and end) of each trial during both thinking processes. The results of the present study extend previous findings in the visuo-spatial knowledge domain, using a highly similar analytical approach to investigate divergent and convergent thinking. Together, these findings provide theoretical implications on how divergent and convergent thinking interact beyond WM across different knowledge domains by emphasizing their complex interplay.

语言知识领域发散思维和聚合思维时间动态的脑电图振荡证据
本研究调查了语言知识领域中发散思维和聚合思维的神经机制,同时考虑了与工作记忆(WM)相关的激活。发散思维通过 "交替使用任务"(AUT)进行评估,收敛思维通过 "复合远程联想任务"(RAT)进行评估。我们分析了α波段上部(10-12赫兹)的振荡活动,在这两个任务中,我们通过在每次试验中调查三个不同的时间点来考虑两个思维过程的时间动态。我们还减去了通过在同一知识领域内进行连续回忆任务以及使用与发散思维和聚合思维任务高度相似的刺激材料所测得的与 WM 相关的振荡活动。我们的研究结果表明,相对于收敛思维,发散思维过程中存在较强的上阿尔法同步现象,这种现象在前顶叶电极上最为明显。此外,我们还观察到,在两种思维过程中,每次试验的中间(而不是开始和结束)同步化程度最高。本研究的结果扩展了之前在视觉空间知识领域的发现,使用了高度相似的分析方法来研究发散思维和收敛思维。这些研究结果强调了发散思维和聚合思维之间复杂的相互作用,从而对不同知识领域的发散思维和聚合思维如何在WM之外相互作用提供了理论意义。
