Perceptual-motor deficiency in autistic children

15 autistic children were matched with normals on the Beery-Buktenica Developmental Test of Visual-motor Integration. The two groups were subsequently compared on ability to (1) increase geometric figure-copying performance using additional information provided during subsequent trials, (2) make figure-ground resolutions, (3) perform a fine motor integration task, and (4) cope with background interference while responding on the Developmental Test of Visual-motor Integration. The primary deficit observed in the autistic subjects appeared to be defective monitoring of the motor response.
