This experiment examined how multiple planning constraints affect grasp posture planning in 6- to 10-year-old children (n = 16 in each group) by manipulating the intended object end-orientation (left end-down, right end-down) and initial precision demands (standard, initial precision) of a bar transport task. Results indicated that grasp posture…

We used a three-component multiple-schedule with a brief reversal design to evaluate the effects of structurally unmatched and matched stimuli on immediate and subsequent vocal stereotypy that was displayed by three children with autism spectrum disorders. For 2 of the 3 participants, access to matched stimuli, unmatched stimuli, and music…

A study compared the motor coordination of 26 Japanese children (ages 6-15) with Asperger syndrome and 14 with learning disabilities using the Movement Assessment Battery for Children. Although no relationship was found between intellectual and motor function, both groups demonstrated motor delay. Children with autism had poorer ball skills. (CR)
