Neural alignment during moral persuasion shows distinct patterns. Frontal brain regions exhibit more dissimilarity, while alpha-band activity shifts from divergence to convergence across interaction phases, aiding resolution.
Area of Science:
- Neuroscience
- Social Cognition
- Psychology
Background:
- Moral persuasion involves complex cognitive and emotional integration.
- Understanding neural coordination during dyadic moral discussions is crucial.
Purpose of the Study:
- Investigate phase-specific neural alignment during dyadic moral persuasion.
- Examine coordination of cognitive, emotional, and regulatory processes using EEG hyperscanning.
Main Methods:
- Utilized electroencephalography (EEG) hyperscanning in 14 same-gender dyads.
- Analyzed inter-brain dynamics across four discourse phases of a moral dilemma dialogue.
- Assessed power spectral density in frontal, temporo-parietal, and parieto-occipital regions across five EEG bands.
Main Results:
- Greater inter-brain dissimilarity observed in frontal over posterior regions, especially in delta and gamma bands.
- Alpha-band dissimilarity varied by phase: higher divergence during persuadee's perspective disclosure (PPD), increased convergence during conclusion (FCP).
Conclusions:
- Findings suggest differentiated regulatory and evaluative processes between participants.
- Phase-dependent neural alignment patterns may reflect initial cognitive divergence followed by resolution-focused convergence.
- Inter-brain dynamics offer insights into neural support for role- and phase-dependent processes in moral persuasion.
