A06: Decoding dynamic reciprocal neural mechanism underlying reactive aggression: Insights from fMRI and fNIRS hyperscanning
The project employs fMRI and functional near-infrared
spectroscopy (fNIRS) hyperscanning techniques to explore how brain-to-brain synchrony and dynamic processes within
peer dyads facilitate or inhibit aggressive behavior under diverse levels of provocation in adolescent patients and controls.
In two fully interactive tasks, we will probe aggressive behavior towards a task partner, and quantify the building of
interpersonal trust/distrust applying a social interaction and economic exchange paradigm. These paradigms will be
employed within dyads in fMRI hyperscanning settings and extended by group-based fNIRS methods in triads to study
effects of peers, social exclusion, and coalitions on aggressive behavior in semi-naturalistic interactions. Between-brain
neural synchrony will be computed and related to everyday social experiences and individual predispositions to identify
markers for the prediction of aggressive behavior.
