Intentional sadness contagion: Social bonding with neural decoupling

Area of Science:

• Neuroscience
• Social Psychology
• Cognitive Science

Background:

• Intentional emotional contagion mechanisms are unclear in natural communication.
• Conscious engagement can enhance emotional contagion.

Purpose of the Study:

• Investigate the neurobehavioral mechanisms of intentional sadness contagion.
• Examine how intentional emotional contagion affects interpersonal intimacy and altruism.
• Extend the Emotions as Social Information Model.

Main Methods:

• fNIRS pseudo-hyperscanning to measure brain activity during dyadic communication.
• Behavioral assessments of interpersonal intimacy and listener altruism.
• Mediation analysis to explore emotional communication and self-other overlap.

Main Results:

• Behavioral: Increased interpersonal intimacy and listener altruism.
• Neurocognitive: Reduced activation in specific prefrontal and parietal regions.
• Neural Synchronization: Weaker synchronization between speaker's and listener's dlPFC.
• Mediation: Intentional emotional contagion linked emotional communication and self-other overlap.

Conclusions:

• Intentional sadness contagion shows a behavioral-neural dissociation.
• Adaptive neurocognitive reorganization facilitates prosocial behavior during dyadic story sharing.
• Findings support and extend the Emotions as Social Information Model.
