Abstract [en]

Isochronous serial interval production (ISIP) data, as from unpaced finger tapping, exhibit higher-order dependencies (drift). This fact has largely been ignored by the timing literature, one reason probably being that influential timing models assume random variability. Men and women, 22-36 years old, performed a synchronization-continuation task with inter-tap intervals (ITI) from 0.4 s to 2.2 s. ISIP variability was partitioned into components attributable to drift and first-order serial correlation, and the results indicate that (a) drift contributes substantially to the dispersion for longer ITIs, (b) drift and first-order correlation are different functions of the ITI, and (c) drift exhibits breaks close to 1 s and 1.4 s ITI. These breaks correspond to qualitative changes in performance for other temporal tasks, which suggests common timing processes across modalities and tasks.
