This study explored the structure of elementary cognitive tasks (ECTs) and relations between the corresponding construct(s) with processing speed (Gs) and fluid intelligence (Gf). Participants (N=321) completed 14 ECTs, 3 Gs, and 6 Gf marker tests, all administered in paper-and-pencil format to reduce potential confounds evident when tasks are presented using different media. Factor analysis of the ECTs resulted in a general mental speed factor, along with several task-class specific factors. General mental speed was indistinguishable from Gs and highly correlated with Gf. Significant correlations were also found between Gf and variance specific to task-class speed factors. The findings point to the non-unitary nature of mental speed and the potentially important role of specific speed factors for examining the relationship between speed and fluid intelligence.
