Experiencing positive emotions together facilitates interpersonal understanding and promotes subsequent social interaction. This study used functional near-infrared spectroscopy-based hyperscanning to discover that watching a happiness movie together leads to higher interpersonal neural synchronization, resulting in more effective coordination interaction during interpersonal cooperation tasks.
Experiencing positive emotions together facilitates interpersonal understanding and promotes subsequent social interaction among individuals. However, the neural underpinnings of such emotional-social effect remain to be discovered. The current study employed the functional near-infrared spectroscopy-based hyperscanning to investigate the abovementioned relationship. After participants in dyad watched movie clips with happily or neutral emotion, they were asked to perform the interpersonal cooperative task, with their neural activation of prefrontal cortex being recorded simultaneously via functional near-infrared spectroscopy. Results suggested that compared with the neutral movie watching together, a higher interpersonal neural synchronization (INS) in left inferior frontal gyrus during participant dyads watching happiness movie together was observed. Subsequently, dyads in happiness showed more effective coordination interaction during the interpersonal cooperation task compared to those in the neutral condition, and such facilitated effect was associated with increased cooperation-related INS at left middle frontal cortex. A mediation analysis showed that the coordination interaction fully mediated the relationship between the emotion-induced INS during the happiness movie-viewing and the cooperation-related INS in interpersonal cooperation. Taken together, our findings suggest that the faciliatory effect experiencing happiness together has on interpersonal cooperation can be reliably reflected by the INS magnitude at the brain level.
