Results indicated that the lack of hand preference in children with autism was not a function of their cognitive delay or a lack of motor skills. Results supported the bilateral brain…

A study of children (ages 3-5 and 11-13) with autism (n=35), learning disabilities (n=26), or no disabilities (n=90) found that the nondisabled children were more lateralized than others in degree and consistency of handedness. No evidence was found of a dissociation of hand skill and hand preference in children with autism, compared to others.…

This study found that motor impairment levels of 12 Asperger syndrome children and 9 high functioning autistic children (ages 7-17) did not differ. Intelligence level was negatively correlated with motor impairment. Fifty percent of Asperger children and 67% of children with autism showed a clinically significant level of motor impairment.…

Subjects with autism (n=36) were assigned a simple "reach, grasp, and place" task. Comparison with nonautistic children who had mental retardation and younger normally developing children found that the autistic subjects had problems in executing goal-directed motor acts even in very simple situations, suggesting an independent and marked…

A method for empirical classification of autistic and autisticlike children, based on behavior observations of 35 males and 11 females (ages 4-28 years) was examined. Factor and cluster analysis indicated four subtypes, characterized by perseverative thinking and play, motor disturbances, schizotypal/schizoid features, and anxiety and negativism.…
