Previous studies investigating aggression adopted paradigms that measured the neural correlates of reactive aggression in single participants interacting with an ostensible opponent. However, this approach provides limited insight into social interactions. By measuring the activity of more than one brain simultaneously, hyperscanning allows for investigating the neural underpinnings of social interactions. Nevertheless, whether dynamic inter-brain dependence during real interactions differs from when participants only believe to be interacting with each other is yet unknown. This project aims to answer this question by developing and testing a paradigm to investigate decision-making during aggressive interactions between dyads of non-related healthy adults. In the paradigm, participants choose between harming the self and harming the other via aversive stimuli. The goal is to understand the influence of reward and punishment on dynamic inter-brain dependence during real aggressive interactions and if dynamic inter-brain dependence changes when participants really interact or only believe to be doing so. |
