Inferior Auditory Time Perception in Children With Motor Difficulties

Child Development, 92(5):e907-e923.

Accurate time perception is crucial for hearing (speech, music) and action (walking, catching). Motor brain regions are recruited during auditory time perception. Therefore, the hypothesis was tested that children (age 6–7) at risk for developmental coordination disorder (rDCD), a neurodevelopmental disorder involving motor difficulties, would show nonmotor auditory time perception deficits. Psychophysical tasks confirmed that children with rDCD have poorer duration and rhythm perception than typically developing children (N = 47, d = 0.95–1.01). Electroencephalography showed delayed mismatch negativity or P3a event‐related potential latency in response to duration or rhythm deviants, reflecting inefficient brain processing (N = 54, d = 0.71–0.95). These findings are among the first to characterize perceptual timing deficits in DCD, suggesting important theoretical and clinical implications.
