摘要

思维定势是一种认知偏差,它源于反复使用刻板的解决问题策略,这可能会阻碍新的和创造性的想法。然而,心理集诱导的神经机制尚不清楚。我们假设重复使用一种策略会增加神经表征的相似性,从而产生一种心理集合。为了验证这一点,我们使用相同的松散块分解问题解决策略,在连续呈现的思维模式诱导试验中进行了代表性相似性分析。这种归纳预计会损害后续探针试验的解决,需要更有洞察力的紧密块分解策略。结果表明,在松散块分解归纳阶段,神经表征相似性增加,特别是在认知控制、心理操作和默认模式网络相关的区域。这些增加预示着在紧密块分解试验中前扣带皮层和内侧额叶的激活。此外,内侧额叶调节了心理集诱导过程中相似性增加的影响,影响了知觉、操作和执行加工区域从松散块分解到紧密块分解的表征变化。综上所述,我们的研究结果表明,目标导向心理操作网络和默认模式网络中神经表征相似性的增加支持心理集合归纳,增强了不同策略下创造性问题解决过程中的冲突解决和表征变化。

The induction of a specific mental set for problem solving is accompanied by increased neural representational similarities.

A mental set is a cognitive bias that results from repeatedly applying a stereotypical problem-solving strategy, which can hinder new and creative ideas. However, the neural mechanisms underlying mental set induction remain unclear. We hypothesized that repeated use of a strategy increases neural representation similarity, thus producing a mental set. To test this, we conducted representational similarity analysis across continuously presented mindset-induction trials using the same loose chunk decomposition problem-solving strategy. This induction was expected to impair the solving of subsequent probe trials requiring a more insightful tight chunk decomposition strategy. Results showed that neural representational similarity increased across loose chunk decomposition induction stages, particularly in regions related to cognitive control, mental operations, and the default mode network. These increases predicted activation in the anterior cingulate cortex and medial frontal lobe during tight chunk decomposition trials. Furthermore, the medial frontal lobe moderated the impact of increased similarity during mental set induction, affecting representational changes from loose chunk decomposition to tight chunk decomposition in perceptual, operative, and executive processing regions. In summary, our findings suggest that increased neural representational similarity in goal-directed mental manipulation networks and the default mode network supports mental set induction, enhancing conflict resolution and representational change during creative problem-solving with different strategies.

期刊介绍: Cerebral Cortex publishes papers on the development, organization, plasticity, and function of the cerebral cortex, including the hippocampus. Studies with clear relevance to the cerebral cortex, such as the thalamocortical relationship or cortico-subcortical interactions, are also included. The journal is multidisciplinary and covers the large variety of modern neurobiological and neuropsychological techniques, including anatomy, biochemistry, molecular neurobiology, electrophysiology, behavior, artificial intelligence, and theoretical modeling. In addition to research articles, special features such as brief reviews, book reviews, and commentaries are included.
