Restructuring refers to achieving satisfactory solutions by breaking obstacles or forming novel associations in problem‐solving. One critical question arises regarding how an appropriate solution is processed in our brain during the restructuring of problem representations. This study aims to explore the electrophysiological correlates of appropriateness evaluation of restructuring by employing a chunk decomposition task. During loose or tight chunk decomposition, participants needed to assess whether they could get a valid solution after probe removal from a source character chunk. As reflected by the late positive complex, the processing of appropriateness exhibited the greatest effect (appropriate vs. inappropriate) in left parietal regions for tight chunk decomposition, but exhibited insignificant differences across most brain regions for loose chunk decomposition. This study provides the first primary electrophysiological evidence that both hemispheres contribute to and the left hemisphere plays a predominant role in evaluating the appropriateness of restructuring in problem solving.

块分解问题求解过程中重构适当性评价的左半球优势

重构是指通过在解决问题中打破障碍或形成新的联想来获得令人满意的解决方案。在重构问题表征的过程中，我们的大脑中如何处理适当的解决方案，这是一个关键问题。本研究旨在通过采用块分解任务来探索重组适当性评估的电生理相关性。在松散或紧密块分解期间，参与者需要评估从源字符块中删除探针后他们是否可以获得有效的解决方案。正如后期正复合体所反映的那样，适当性处理在左顶叶区域对紧密块分解表现出最大的影响（适当与不适当），但在松散块分解的大多数大脑区域中表现出微不足道的差异。这项研究提供了第一个主要的电生理学证据，表明在评估重组解决问题的适当性方面，两个半球都有贡献，并且左半球起主要作用。
