| Abstract | Examined the effects of sensory information and internally generated temporal expectations on phase correction following a perturbation in sensorimotor synchronization . Eight individuals (aged 19-55 yrs) completed tasks requiring finger tapping in synchrony with isochronous auditory sequences containing a single shifted event onset, with or without a gap of up to 3 missing events and with or without phase shifting. Subjects were instructed to not react to the shifted event and to continue tapping regularly during any gap. Results show that the shifted event caused an involuntary phase shift of the following tap. The shift was corrected if the sequence continued, but during the gap the shift persisted without correction. It is concluded that sensory feedback is necessary for phase correction to occur. |
