Dispositional empathy as a driver of inter-individual neural phase synchrony

Area of Science:

• Social Neuroscience
• Cognitive Neuroscience
• Neuroscience

Background:

• Inter-individual neural phase synchrony is a key phenomenon in social neuroscience.
• Its underlying cognitive processes, especially during collaboration, are not well understood.

Purpose of the Study:

• To investigate dispositional empathy as a driver of inter-individual neural synchrony.
• To explore the role of empathy in neural synchrony during a collaborative task.

Main Methods:

• Utilized electroencephalography (EEG) on 46 participants during a face-to-face collaborative task.
• Measured inter-individual neural phase synchrony using circular correlation coefficients across frequency bands.
• Assessed dispositional empathy, focusing on imaginative transposition.

Main Results:

• Found significant inter-brain synchrony in high alpha, beta, and gamma frequency bands.
• Observed prominent synchrony between central brain regions and other areas.
• Dispositional empathy, specifically imaginative transposition, predicted beta and gamma band synchrony.

Conclusions:

• Dispositional empathy significantly contributes to the emergence of inter-individual neural phase synchrony.
• Empathy acts as a crucial factor in synchronizing brain activity between collaborating individuals.
• Findings highlight the neural basis of empathy in social interaction.
