Whose action? Self-other integration during rhythmic joint action

Interpersonal coordination is a core part of human interaction, and its underlying mechanisms have been extensively studied using social paradigms such as joint finger-tapping. Here, individual and dyadic differences have been found to yield a range of dyadic synchronization strategies, such as mutual adaptation, leading–leading, and leading–following behaviour, but the brain mechanisms that underlie these strategies remains a topic of active research. In this talk I will present results from an EEG-study where we identified an action-perception related network as linked to synchronization strategies in rhythmic joint action. I propose that this network may also serve as an indicator of self-other integration, and present a model that capture some key features of rhythmic joint action.
