This study examined the timing of synchronous finger tapping to continuous frequency modulation (FM) and to click trains. Tapping to click trains was found to statistically significantly anticipate the acoustic stimulus. Tapping to continuous FM occurred before the instantaneous frequency rose through its mean value (i.e. at zero phase of the sinusoidal FM). The anticipation of zero phase of the FM was similar in magnitude to the anticipation of the click stimuli. However, there was a systematic departure from this timing when the FM depth was varied, the cause of which is unclear. The perceived timing of acoustic stimuli will influence the timing of motor responses to the stimuli. These results may therefore be relevant to the timing of perceptual centres of acoustic stimuli including speech.
