Relationship between Fluid Intelligence and Working Memory

Abstract

This article reviews research which has investigated the relationship between fluid intelligence (Gf) and working memory (WM). Fluid intelligence plays an important role in various cognitive abilities; however this aspect of ability is known to decline with age. Some studies relate to the development of fluid intelligence using brain training programs based on working memory, including both psychological and neurological perspectives. A particular focus of this article is with reference to anatomical structure, and to causal WM-Gf relationships which seem likely to form the basis for further research on the development offluid intelligence.
