Neural oscillatory dynamics serving abstract reasoning reveal robust sex differences in typically-developing children and adolescents


" Interestingly, our follow-up analyses indicated that only specific regions of neural oscillatory activity significantly mediated the relationship between age and abstract reasoning task performance. Among males, increased theta synchronization in superior frontal gyrus, dorsolateral prefrontal cortex, and inferior parietal lobule fully explained the association between increasing age and faster reaction times. Conversely, among females, decreased theta synchronization in dorsolateral prefrontal cortex and inferior frontal gyrus partially explained the relationship between increasing age and better accuracy on the task. The specific relationship between activity in these regions and abstract reasoning task performance further corroborates the P-FIT model of fluid intelligence (Jung and Haier, 2007), and strengthens support for the conclusion that the neural networks underlying abstract reasoning abilities follow sexually-divergent developmental trajectories between during adolescence." {Credits 1}
