Sex and handedness in development of visuomotor skills.
Development of visuomotor skills in 420 left-banded and 420 right-handed school children were investigated using the Rey-Osterrieth Complex Figure. Analysis indicate that the visuomotor skills involved in copying a complex figure improve with age until the mean age of 10.5 yr., in both sex and handedness groups. Further analysis showed that girls performed significantly better than boys at certain developmental stages and right-handers performed better than left-handers in various age groups. Some possible differences in performance could be attributed to different rates of maturation of the cerebral hemispheres, to different neuropsychological strategies, or to functional differences between the sex groups and between right- and left-handed children.
