This study aimed to determine how gender composition affects the group creative process. Participants were recruited into dyads with different gender compositions (female-male dyad, F-M; female-female, F-F; male-male, and M-M) to solve two problems. One problem demanded creativity alternative use task (AUT) and the other did not object characteristic task. Functional near-infrared spectroscopy (fNIRS)-based hyperscanning was used to record interpersonal neural responses. Results demonstrated no significant difference in creative performance among the three types of dyads. However, the F-F dyad showed higher levels of cooperative behaviour (i.e. the index of convergence) and collective flexibility than the other dyads. Also, in the fNIRS data, the F-F dyad showed higher interpersonal brain synchronization (IBS) increments in the right posterior parietal cortex during the AUT than the other dyads, which covaried with their creative performance. These findings indicate that while solving a creativity problem together, females are more likely than males to consider others' perspectives. This gender difference might be due to the enhanced IBS increment in the right posterior parietal cortex.
本研究旨在确定性别构成如何影响群体创造性过程。参与者被招募到具有不同性别构成的二人组中（女性-男性二人组、F-M；女性-女性、F-F；男性-男性、M-M），以解决两个问题。一个问题需要创造力的替代用途任务（AUT），另一个不需要对象特征任务。使用基于功能近红外光谱（fNIRS）的超扫描记录人际神经反应。结果表明，三种类型的二人组在创造性表现方面没有显著差异。然而，F-F 二人组的合作行为（即收敛指数）和集体灵活性水平均高于其他二人组。此外，在 fNIRS 数据中，F-F 二人组在解决 AUT 时右后顶叶皮层的人际脑同步（IBS）增量高于其他二人组，这与他们的创造性表现相关。这些发现表明，在共同解决创造性问题时，女性比男性更倾向于考虑他人的观点。这种性别差异可能归因于右后顶叶皮层 IBS 增量的增强。
