Toward a Theory of Aptitude for Learning I. Fluid and Crystallized Abilities and their Correlates

Part of the NATO Conference Series book series (NATOCS, volume 14)


This paper focuses on the psychology of aptitude for learning in formal educational settings, and particularly on the nature of measured cognitive abilities as aptitudes. This is only a part of what is needed for a theory of aptitude, but it is perhaps the best place to start: the concept of aptitude has been connected with formal schooling almost since their mutual beginnings, and more scientific evidence is now available about the role of aptitude here, as measured by mental tests, than about aptitude, however measured, in any other natural or social situation. Whatever else it does, a theory of aptitude will need to account for the accumulated evidence about mental test performance in relation to learning from instruction.
