The shape of the transition in multisensory integration between the (defensive) peripersonal space (DPPS) and the extrap-ersonal space (EPS) has recently been debated. Contributing to this discussion, we approached the DPPS-EPS transitionfrom a dynamic systems perspective. Specifically, the dynamic complexity of visuotactile reaction times to moving stimuliwas employed to evaluate the presence of phase transitions. Reecting well-established ndings on the DPPS-EPS transi-tion, we hypothesized that a phase transition would be identied for looming stimuli, but not for receding stimuli, andthat the phase transition for looming threatening stimuli would be located further away from the body than for loomingnon-threatening stimuli. Contrary to these hypotheses, we found that phase transitions for receding stimuli were moreprominent and located further away from the body than phase transitions for looming stimuli. Nonetheless, we considerthe identification of phase transitions to be a promising approach for future studies of multisensory integration.
