Gender, handedness, speed, and visuoconstructive performance in public junior high school students: a neurobehavioural approach

Previous studies onvisuoconstructionalperformance using Three-Dimensional Block Construction Test in Jakartawere performed in patients with stroke and brain injury, but not yet carried out in normal subjects. This study analyzed the individual dfli"rinc", in visuoconstructiveperformancelevel, betweenboysandgirls,andbetweenright-handersandnon-right-handers.Furthermoie,thespeed associated with the ight and left hemisphere functions was analyzed. The result of the test ising the Three-Dimensional Block Construction Test in 166 students of the public yunior high school with an age range of 12-16 years showed no significant dffirences invisuoconstructiveperformance and speedbetweenboys and girls, andbetween right-handers andnon-right-handers. The timi-required to finish the tasks was shorter in boys than girls, although stafisrtcally it was not significant. It seems that at the age range biiateral brain organilation exists so that the tvvo sexes present no dffirence in th.eirvisuoconstructive performance. Howeyer, before i conclusion can be reached, further studies should be conducted in larger scale using the same methodololy.
