Abstract
Movement variability in many rhythmic behaviors often exhibits characteristic temporal structures. In gait and tapping, stride to stride, and beat to beat variations are marked by long-term correlations in time. Motivated by evidence suggesting that changes in the temporal structure of movement variability often accompanies pathology, we explore the possibility manipulating the temporal structure of movement using variants of structured auditory stimuli to which participants in our experiments intentionally coordinated. Stimuli comprised of a rhythmic metronomic beat with varying temporal noise structures (e.g. white, pink, brown) were investigated in both tapping and locomotion tasks. Our results show that the stimuli were effective at changing the variability structure of the observed movement patterns. We also report an accompanying analyses of cortical involvement measured through functional near-infrared spectroscopy.
