Timing variability in circle drawing and tapping: probing the relationship between event and emergent timing.

ABSTRACT. R Ivry, R M Spencer H N Zelaznik, and J Diedrichsen (2002) have propos a distinction between timed moves in which a temporal representation is part of the task goal (event timing) and those in which timing properties are emergent The issue addressed in the not absent experiment was how timing in conditions conducive to emergent timing becomes established. According to what the authors limit the transformation hypothesis, timing initially requires an event-based representation when the temporal goal is defined externally (eg by dint of a metronome), but over the first
