Non-verbal sensorimotor timing deficits in children and adolescents who stutter.

摘要: There is growing evidence that motor and speech disorders co-occur during development. In the present study, we investigated whether stuttering, a developmental disorder, associated with predictive timing deficit in childhood adolescence. By testing sensorimotor synchronization abilities, aimed to assess dysfunctional young participants who stutter (8–16 years). Twenty German children adolescents 43 non-stuttering matched for age musical training were tested on their ability synchronize finger taps periodic tone sequences beat. Forty percent of 90% displayed poor both metronome stimuli, falling below 2.5% estimated population based performance group without disorder. Synchronization deficits characterized by either lower accuracy or consistency both. Lower resulted an over-anticipation pacing event stutter. Moreover, individual profiles revealed was typical severely stuttering. These findings support idea malfunctioning auditory–motor coupling plays role stuttering adolescents.
