Young adolescentsand adults performed a transitive reasoning task, subsequent to undergoinganatomical magnetic resonance imaging (MRI) brain scans. Behaviorally, adultsreasoned more accurately than did the young adolescents. Neural resultsshowed (i) less grey matter density in superior parietal cortex in the adultsthan in the young adolescents, possibly due to a developmental period ofsynaptic pruning; (ii) improved performance in the reasoning task was negativelycorrelated with grey matter density in superior parietal cortex in theadolescents, but not in the adult group; and (iii) the latter results were drivenby the more difficult trials, requiring greater spatial manipulation. Takentogether, the results support the idea that during development, regions insuperior parietal cortex are fine-tuned, to support more robust spatial manipulation,resulting in greater accuracy and efficiency in transitive reasoning.
