Van der Maas, Dolan, Grasman, Wicherts, Huizenga & Raijmakers (2006) proposed a new theory of general intelligence based on the idea of mutualistic interactions during development between the cognitive processes underlying intelligence. They showed that such interactions lead to a positive manifold of correlations between scores on cognitive tasks. This theory is an important alternative for the standard g theory (Jensen, 1998), which conceptualized g as a single latent dimension. The aim of this project is to further investigate the mutualism model. Topics are: model extension, model equivalence, evidence from experimental data, and evidence from longitudinal correlational data.
