摘要: Despite the fact that developmental coordination disorder (DCD) is characterised by a deficit in ability to learn or automate motor skills, few studies have examined learning over repeated trials. In this study we procedural group of 10 children with DCD (aged 8–12 years) and age-matched controls without DCD. The task was modelled on Nissen Bullemer [Cognitive Psychology 19 (1987) 1]. Children performed serial reaction time (SRT) which they were required spatial sequence itself every not aware repetition. Spatial targets four (horizontal) locations presented computer monitor. responded using response keys same horizontal mapping as stimulus. They tested five blocks 100 trials each. first repeating sequence, while fifth block randomised. Procedural indexed slope regression RT 1–4. Results showed most displayed strong despite having no explicit knowledge about it. Overall, there difference magnitude – within normal range. for simple sequential movements appears be intact This suggests cortico-striatal circuits are strongly implicated sequencing appear function normally
