Studies conducted over the last 35 years have indicated that deficits in motor timing are common in children with dyslexia. A number of hypotheses have been proposed in order to link temporal processing deficits on isochronous and non-isochronous rhythmic tasks to the core symptoms of dyslexia such as impaired phonological processing. However, the location of the timing difficulty in these children within the neural network responsible for temporal processing remains unclear. Re-examining the characteristics of motor timing in children with dyslexia will help to determine the primary loci of the deficit. Previous research and recent findings from our own lab demonstrating the different features of motor timing in children with dyslexia will be reviewed (features such as increased performance variability, increased tap-tone asynchrony and slower responses to phase and period shifts, when performing to isochronous stimuli). This research will be discussed alongside evidence for the contribution of different parts of the neural timing system to timing behaviour. The conclusion will focus on what this profile of difficulties tells us about the likely location of the motor timing impairment within the temporal processing system in children with reading difficulties. Examples of atypical developmental can help to shed light on the functional mechanisms through which timing ability develops within typically developing children.
