Similarity in greater Chinese ideology is associated with intersubject neural similarity during viewing of a pro-China video

Higher Greater Chinese ideology is linked to greater positive engagement and more similar neural dynamics during viewing of the same pro-China video in Taiwan samples.

• Why it matters: People watching the same political narrative can interpret it differently, and it is unclear how national identity ideology relates to inter-individual neural dynamics in sociopolitical contexts.
• What they did: Study 1 (N = 52) tested Greater Chinese ideology against positive engagement, and Study 2 (N = 60) used fMRI with intersubject representational similarity analysis during the same pro-China video.
• The result: Greater similarity in Greater Chinese ideology item-response profiles predicted greater neural dynamics similarity in frontoparietal control, salience, and default mode regions, with a stronger within-versus-between effect at relatively lower ideology scores.
