In this talk I will present novel data from a recent experiment where we found that nasally administered oxytocin enhances synchrony in a dyadic tapping task. Specifically, in comparison with placebo, oxytocin led to reduced tapping variability in followers when tapping with an unresponsive partner (unidirectional condition) and increased tapping speed in interactive tapping (bidirectional condition). These findings are discussed in the context of previous literature and future research ideas. (The study presented here is collaborative work with Line Gebauer, Maria Witek, Jana Thomas, Ivana Konvalinka, & Peter Vuust)
