The open question of sex differences in the diagnostic use of the Developmental Bender Scoring System for Young Children remains a troubling issue. These differences have been often obscured by the failure to designate clear diagnostic categories or to control for maturational effect. The present study accounts for each of the above variables and their interaction through multivariate design. The presence of a significant sex difference among these 478 children from a clinic population demonstrates the need for further exploration of sex differences in visual motor performance.
