Scores on
cognitive tasks used in intelligence tests correlate positively with each
other, that is, they display a positive manifold of correlations. The positive
manifold is often explained by positing a dominant latent variable,the g factor,associated
with a single quantitative cognitive or biological process or capacity. In this
article,a new explanation of the positive manifold based on a dynamical model
is proposed,in which reciprocal causation or mutualism plays a central role. It
is shown that the positive manifold emerges purely by positive beneficial interactions
between cognitive processes during development. A single underlying g factor
plays no role in the model. The model offers explanations of important findings
in intelligence research,such as the hierarchical factor structure of
intelligence,the low predictability of intelligence from early childhood
performance,the integration/differentiation effect, the increase in
heritability of g,and the Jensen effect,and is consistent with current
explanations of the Flynn effect.
