People can solve problems in more than one way. Two general strategies involve (A) methodical, conscious, search of problem-state transformations, and (B) sudden insight, with abrupt emergence of the solution into consciousness. This study elucidated the influence of initial resting brain-state on subjects' subsequent strategy choices. High-density electroencephalograms (EEGs) were recorded from subjects at rest who were subsequently directed to solve a series of anagrams. Subjects were divided into two groups based on the proportion of anagram solutions derived with self-reported insight versus search. Reaction time and accuracy results were consistent with different cognitive problem-solving strategies used for solving anagrams with versus without insight. Spectral analyses yielded group differences in resting-state EEG supporting hypotheses concerning insight-related attentional diffusion and right-lateralized hemispheric asymmetry. These results reveal a relationship between resting-state brain activity and problem-solving strategy, and, more generally, a dependence of event-related neural computations on the preceding resting state.
人们可以通过多种方式解决问题。两种常见策略包括：（A）有条不紊、有意识地搜索问题状态的转变，以及（B）突然顿悟，即解决方案突然出现在意识中。本研究阐明了初始静息脑状态对受试者后续策略选择的影响。在受试者静息时记录高密度脑电图（EEG），随后指导他们解决一系列变位词问题。根据自我报告的顿悟与搜索得出的变位词解决方案比例，将受试者分为两组。反应时间和准确性结果与用于有顿悟和无顿悟情况下解决变位词的不同认知问题解决策略一致。频谱分析得出静息状态EEG的组间差异，支持了有关顿悟相关注意力扩散和右侧半球不对称的假设。这些结果揭示了静息状态脑活动与问题解决策略之间的关系，更普遍地说，揭示了事件相关神经计算对先前静息状态的依赖性。
