urn:hdl:10459.1/468356 Fluid-crystallised abilities and academic achievement in secondary education and university Blanch Plana, Angel Blanco Calvo, Eduardo Fluid and crystallized abilities Investment hypothesis Academic performance This study addresses the investment hypothesis of fluid on crystallised abilities onto academic achievement (Gf → Gc → Achievement), which might hold to a greater extent at earlier than at latter educational stages. We compared this prediction with two independent groups of secondary (n = 192, 113 females) and university students (n = 210, 178 females). Structural equation models were used to evaluate the association between Gf-Gc and general intelligence (g) with academic achievement. Moreover, direct and mediation models (Gf → Gc → Achievement) represented the data better than a g-factor model in both groups of students. Direct and indirect effects of Gf-Gc were alike across both groups of students. A larger amount of variability in achievement, however, emerged for secondary students compared with university students, suggesting a more robust support for the investment hypothesis at the earlier educational stage.
