Abstract
180 elementary school children, ranging in age from 6 to 14 yr., were tested for their ability to reproduce geometric forms by means of direct copy on paper with pencil. The forms varied in complexity, as defined by the number of sides. Complexity was found to be negatively associated with level of performance in form reproduction, especially for forms of 8 sides or fewer. Performance in form reproduction was positively associated with age but some age-related inversions were noted.
