In this study we used the Rey-Osterrieth complex figure to examine the visuomotor organization of 514 boys and girls, aged 5.5 to 20.5 yr. All were left-handed as judged by the Edinburgh Handedness Inventory. Statistical evaluation showed significant differences in the visuomotor organization for boys and girls across the various age groups. Statistically significant differences also appeared between the two sexes at the age groups 7.5 to 8.5 and 8.5 to 9.5, with girls showing better organization than boys.
