Educational diversity is defined as the diversity of educational backgrounds measured by multiple subjects. This study aimed to unveil the interpersonal neural correlates that underlie the effect of group educational diversity on group creativity. One hundred and sixteen college students were assigned to high educational diversity (HD; the members respectively majored in science or social science) or low educational diversity (LD; the members both majored in either science or social science) groups based on their academic majors. They were required to solve two problems that either demanded creativity (alternative uses task, AUT) or not (object characteristics task). We used functional near-infrared spectroscopy (fNIRS)-based hyperscanning to simultaneously record the neural responses of pairs of interacting participants in each group. The LD group showed more AUT fluency and perspective-taking behaviours than the HD group, whereas no group difference was observed for AUT uniqueness. Additionally, collective flexibility was higher in the HD group than in the LD group. The fNIRS results showed that the interpersonal brain synchronisation (IBS) increments at the right angular gyrus and right primary somatosensory cortex were greater in the LD group than in the HD group. These findings indicate that although high educational diversity benefits cognitive flexibility, it does not necessarily lead to a better idea quality or greater idea quantity. The greater IBS increments and perspective-taking behaviours that we observed in the LD group may account for this.

教育多样性和群体创造力:来自 fNIRS 超扫描的证据

教育多样性被定义为由多个学科衡量的教育背景的多样性。本研究旨在揭示群体教育多样性对群体创造力的影响背后的人际神经相关性。116 名大学生根据其学术专业被分配到高教育多样性(HD;成员分别主修科学或社会科学)或低教育多样性(LD;成员均主修科学或社会科学)组。他们被要求解决两个需要创造力的问题(替代用途任务,AUT)或不需要(对象特征任务)。我们使用基于功能近红外光谱 (fNIRS) 的超扫描来同时记录每组中交互参与者对的神经反应。LD 组比 HD 组表现出更多的 AUT 流畅性和观点采取行为,而 AUT 独特性没有观察到组差异。此外,HD 组的集体灵活性高于 LD 组。fNIRS 结果显示,LD 组右角回和右初级体感皮层的人际脑同步(IBS)增量大于 HD 组。这些发现表明,尽管高度的教育多样性有利于认知灵活性,但并不一定会带来更好的创意质量或更多的创意数量。我们在 LD 组中观察到的更大的 IBS 增量和采取观点的行为可能解释了这一点。而没有观察到 AUT 唯一性的组差异。此外,HD 组的集体灵活性高于 LD 组。fNIRS 结果显示,LD 组右角回和右初级体感皮层的人际脑同步(IBS)增量大于 HD 组。这些发现表明,尽管高度的教育多样性有利于认知灵活性,但并不一定会带来更好的创意质量或更多的创意数量。我们在 LD 组中观察到的更大的 IBS 增量和采取观点的行为可能解释了这一点。而没有观察到 AUT 唯一性的组差异。此外,HD 组的集体灵活性高于 LD 组。fNIRS 结果显示,LD 组右角回和右初级体感皮层的人际脑同步(IBS)增量大于 HD 组。这些发现表明,尽管高度的教育多样性有利于认知灵活性,但并不一定会带来更好的创意质量或更多的创意数量。我们在 LD 组中观察到的更大的 IBS 增量和采取观点的行为可能解释了这一点。fNIRS 结果显示,LD 组右角回和右初级体感皮层的人际脑同步(IBS)增量大于 HD 组。这些发现表明,尽管高度的教育多样性有利于认知灵活性,但并不一定会带来更好的创意质量或更多的创意数量。我们在 LD 组中观察到的更大的 IBS 增量和采取观点的行为可能解释了这一点。fNIRS 结果显示,LD 组右角回和右初级体感皮层的人际脑同步(IBS)增量大于 HD 组。这些发现表明,尽管高度的教育多样性有利于认知灵活性,但并不一定会带来更好的创意质量或更多的创意数量。我们在 LD 组中观察到的更大的 IBS 增量和采取观点的行为可能解释了这一点。
