Sex differences in bimanual co-ordination

This study sets out to explore whether there are sex differences in bimanual co-ordination among children. 140 children aged between 5.8 and 11.8 years were tested on two bimanualco-ordination tasks the ?Threading Beads? and the ?Threadingnuts on bolt?. It was hypothesized that the bimanual co-ordination tasks would put a heavier load on inter-hemispheric communication and therefore also should be in favour of the girls. The results show a clear developmental trend for all children, the older children completing both tasks significantly faster than the younger ones. For the task ?Threading nuts onBolt?, there was also an overall significant sex difference shown in favour of the boys. Split by age groups, this effectwas only significant for the younger children (5 years old).For the older children and the ?Threading Beads?, no other sex or age related differences could be identified. The conclusion is that sex differences in bimanual co-ordination tasks are sex, age and task specific.
