Kognitive, systemische und Verhaltensneurobiologie

This project aims to identify cognitive and emotion control deficits in the context of negative valence and threat interference and their association with ACE in young offenders. Complementary to other projects, this project will focus on a group of young people defined by their propensity to aggression showing at the same time more severe psychopathologies. In a series of studies using multimodal imaging (EEG-fMRI, EEG-sMRI) in combination with naturalistic longitudinal follow-up (ecological momentary assessment (EMA)) B02 will identify the neural mechanisms and predictors of self-regulation deficits as a putative common developmental pathway for both, aggressive behavior, and psychopathology. Additionally, B02 will seek to causally confirm neural network mechanisms of inhibitory control and emotion regulation deficits as the basis of aggressive behavior and associated psychopathology by real-time EEG-triggered TMS-stimulation in young offenders.

Develop virtual scenarios to assess decision strategies in cartoon-like and naturalistic contexts. The core question is how healthy individuals and patients make (mal-)adaptive aggressive decisions in social conflicts given their threat sensitivity, cognitive functions, and learning experience. We plan to present mathematically well-defined aggressive decision scenarios to healthy participants as well as patients across diagnostic categories with high scores of aggressive behavior, threat sensitivity, and inference of hostile intent in others. Computational models that accurately explain behavioral choices and neural responses (tested using fMRI and pupillometry) will be developed to identify the aggressive decision strategies humans employ in approach-avoidance conflicts of increasing complexity and ecological realism. The purpose will be to determine if patients use overly aggressive strategies that are not warranted by the necessary defense of self-threats and underlying neural circuits.
