Exploring possible neural mechanisms of intelligence differences using processing speed and working memory tasks: An fMRI study

To explore the possible neural foundations of individual differences in intelligence test scores, we examined the associations between Raven's Matrices scores and two tasks that were administered in a functional magnetic resonance imaging (fMRI) setting. The two tasks were an n-back working memory (N=37) task and inspection time (N=47). The subjects were members of the Aberdeen Birth Cohort 1936, aged in their mid-late 60s when tested for this study. Performance on both tasks was correlated significantly with scores on Raven's Mamices. In the inspection time task there were regions with significant correlations between the neural activity (BOLD response) and performance but not between BOLD response and scores on Raven's Matrices. In the working memory task there were no significant correlations between BOLD response and either performance or scores on Raven's Matrices. Moreover, there was almost no mediation of the Raven's Matrices versus n-back and inspection time scores correlations by the respective BOLD response. These findings partially replicate important aspects of a prominent report in this field [Gray. J.R., Chabris. C.F., & Braver, T.S. (2003). Neural mechanisms of general fluid intelligence. Nature Neuroscience, 6. 316-322.], but have also extended the those finding into both a unique population and a novel functional task. (C) 2008 Elsevier Inc. All rights reserved.
