Recent investigations suggest that rhythmic movements rely on two distinct timingsystems: event and emergent timing. Event timing is based on an explicit internalrepresentation of the temporal interval marked by clear perceptual detectible events, whereasemergent timing is derived from the dynamics of smooth and continuous movements. Crucialaspects of the distinction between these mechanisms remain unclear. This thesis investigatesthe role of expectancy and skill in the internal representation of time in event and emergenttiming. Chapter 1 introduces the theoretical framework that supports the differentiationbetween event and emergent timing mechanisms and presents the hypotheses that were tested.Chapter 2 describes a series of five experiments that investigated the role of expectancythrough the examination of the effect of a single unexpected perturbation of feedback content(e.g. pitch, timbre, intensity) on timing of finger tapping. Chapter 3 expands this question byinvestigating the effect of unexpected auditory perturbations on two types of timedmovements: finger tapping and circle drawing. The role of expertise and training on motortiming is the subject of discussion of Chapters 4 to 6, where a total of 4 experiments tested theeffect of expertise and music training on accuracy of finger tapping and circle drawing tasks.More specifically, Chapter 4 compares accuracy levels of experts in movement-basedactivities (music and sports) with non experts. Chapters 5 and 6 focus on the effect of musictraining on event and emergent timing in students of 10 to 14 years of age. Finally, Chapter 7reviews and discusses the main findings of this body of work with respect to current theoriesof timing and movement. Foremost, these data challenge current models of humanmovements controlled by event and emergent timing mechanisms demonstrating thatexpectancy and training are crucial in determining the timing strategy and the type ofexpectancy mechanisms adopted to perform distinct rhythmic movements.
