Time intervals production in tapping and oscillatory motion . We applied spectral analysis on series of time intervals produced in a synchronization-continuation experiment . In the first condition intervals were produced by finger tapping , and in the second by an oscillatory motion of the hand . Results obtained in tapping were consistent with a discrete , event-based timing model . In the oscillatory condition , the spectra suggested a continuous , dynamic timing mechanism , based on the regulation of effector stiffness . It is concluded that the oscillatory character of movement can offer an important resource for timing control . The use of an event-based timing control such as postulated in the Wing-Kristoffersson model could be restricted to a quite limited class of rhythmic tasks , characterized by the concatenation of discrete events .
