Studies suggest that internally oriented cognitive processes are central to creativity. Here, we distinguish between intentional and unintentional forms of mind wandering and explore their behavioral and neural correlates. We used a sample of 155 healthy adults from the mind-brain-body dataset, all of whom completed resting-state fMRI scans and trait-level measures of mind wandering. We analyzed intentional and unintentional mind wandering tendencies using self-report measures. Next, we explored the relationship between mind wandering tendencies and creativity, as measured by a divergent thinking task. Finally, we describe patterns of resting-state network connectivity associated with mind wandering, using graph theory analysis. At the behavioral level, results showed a significant positive association between creativity and both intentional and unintentional mind wandering. Neuroimaging analysis revealed higher weighted degree connectivity associated with both forms of mind wandering, implicating core regions of the default network and the left temporal pole. We observed topological connectivity differences within the default network: intentional mind wandering was associated with degree connectivity in posterior regions, whereas unintentional mind wandering showed greater involvement of prefrontal areas. Overall, the findings highlight patterns of resting-state network connectivity associated with intentional and unintentional mind wandering, and provide novel evidence of a link between mind wandering and creativity.
研究表明，内向型认知过程是创造力的核心。在此，我们区分了有意和无意的思维游荡形式，并探讨了它们的行为和神经关联。我们使用了来自心-脑-体数据集的155名健康成年人样本，他们都完成了静息态功能磁共振成像扫描以及思维游荡的特质水平测量。我们使用自我报告测量方法分析了有意和无意的思维游荡倾向。接下来，我们探讨了思维游荡倾向与创造力之间的关系，创造力通过一项发散性思维任务来衡量。最后，我们使用图论分析描述了与思维游荡相关的静息态网络连通性模式。在行为层面，结果显示创造力与有意和无意的思维游荡之间均存在显著的正相关。神经影像学分析揭示，与这两种思维游荡形式相关的加权度连通性更高，涉及默认网络的核心区域和左颞极。我们观察到默认网络内部的拓扑连通性差异：有意的思维游荡与后部区域的度连通性相关，而无意的思维游荡则显示前额叶区域的参与度更高。总体而言，这些发现突出了与有意和无意思维游荡相关的静息态网络连通性模式，并为思维游荡与创造力之间的联系提供了新的证据。
