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.
