title: Auditory-motor synchronization facilitates attention allocation.
abstract: Temporal predictability of auditory events induces larger P300 amplitudes and shorter P300 latencies compared to stimulus presentation with variable onset asynchronies. This suggests that periodic stimuli lead to neuronal entrainment resulting in a more efficient allocation of attentional resources. Simultaneous synchronized motor activity should facilitate the precise temporal encoding of acoustic sequences. Therefore the current event-related potential study investigated whether embodied stimulus encoding enhances the reported effects of stimulus periodicity. We found that simultaneous pedaling on an ergometer compared to a physically passive situation amplified the predictability effect on the P300 component. Furthermore, the temporal variability of cycling behavior correlated positively with both P300 latency and P300 amplitude. These findings indicate that auditory-motor synchronization enhances the attentional processing of periodical auditory stimuli.
