In the last two decades research on the neurophysiological processes of creativity has found contradicting results. Whereas most research suggests right hemisphere dominance in creative thinking, left-hemisphere dominance has also been reported. The present research is a meta-analytic review of the literature to establish how creative thinking relates to relative hemispheric dominance. The analysis was performed on the basis of a non-parametric vote-counting approach and effect-size calculations of Cramer's phi suggest relative dominance of the right hemisphere during creative thinking. Moderator analyses revealed no difference in predominant right-hemispheric activation for verbal vs. figural tasks, holistic vs. analytical tasks, and context-dependent vs. context-independent tasks. Suggestions for further investigations with the meta-analytic and neuroscience methodologies to answer the questions of left hemispheric activation and further moderation of the effects are discussed.
在过去的二十年中，对创造力的神经生理过程的研究得出了相互矛盾的结果。尽管大多数研究表明创造性思维以右脑占优势，但也有报道称左脑占优势。本研究是对文献的元分析综述，旨在确定创造性思维与相对半球优势的关系。该分析是基于非参数投票计数方法进行的，Cramer's phi 的效应大小计算表明，在创造性思维过程中右半球具有相对优势。调节分析表明，在言语与图形任务、整体与分析任务以及依赖与不依赖情境的任务中，右半球的优势激活没有差异。讨论了进一步使用元分析和神经科学方法进行研究的建议，以回答左半球激活的问题，并进一步调节这些影响。
