Educational diversity and group creativity: Evidence from fNIRS hyperscanning

Area of Science:

• Cognitive Neuroscience
• Social Psychology
• Creativity Studies

Background:

• Educational diversity, defined by varied academic backgrounds, is explored for its influence on group creativity.
• Understanding the neural mechanisms behind group dynamics and creativity is crucial for optimizing collaborative innovation.

Purpose of the Study:

• To investigate the interpersonal neural correlates of group educational diversity's effect on group creativity.
• To compare creativity performance and neural synchrony between high and low educational diversity groups.

Main Methods:

• 116 college students were assigned to high (science/social science majors) or low (same major) educational diversity groups.
• Participants completed tasks measuring creativity (alternative uses task, AUT) and non-creative problem-solving (object characteristics task).
• Functional near-infrared spectroscopy (fNIRS)-based hyperscanning measured simultaneous neural activity in interacting pairs.

Main Results:

• The low educational diversity (LD) group exhibited greater AUT fluency and perspective-taking behaviors than the high educational diversity (HD) group.
• No significant difference in AUT uniqueness was found between groups.
• Collective flexibility was higher in the HD group compared to the LD group.
• Increased interpersonal brain synchronization (IBS) in the right angular gyrus and right primary somatosensory cortex was observed in the LD group.

Conclusions:

• High educational diversity enhances cognitive flexibility but does not necessarily improve the quantity or quality of creative ideas.
• Greater IBS and perspective-taking in lower diversity groups may explain their higher fluency.
• The findings suggest a nuanced relationship between educational diversity, neural synchrony, and creative output.
