Audience Interbrain Synchrony During Live Music Is Shaped by Both the Number of People Sharing Pleasure and the Strength of This Pleasure.

Observational EEG hyperscanning cohort study without a control group

What was done
Electroencephalography (EEG) hyperscanning was used to record the cerebral activity of an audience during a live concert. The authors evaluated interbrain synchrony (IBS) during specific moments categorized by strong versus weak emotional pleasure and strong versus weak emotional cohesion among audience members.
What was found
The abstract reports no numerical values, effect sizes, or test statistics. Qualitatively, audience interbrain synchrony was found to be primarily associated with experiencing high musical pleasure. Group emotional cohesion enhanced interbrain synchrony, but was not the primary driver on its own.
Why it matters
This study delineates the neural dynamics of shared aesthetic experiences, suggesting individual pleasure intensity is the main driver of collective neural coupling, with group cohesion playing a secondary, enhancing role.
Limits
The abstract provides no sample size, participant demographics, statistical figures, or baseline control conditions. Findings are reported purely qualitatively, preventing independent assessment of effect size or precision.
