DescriptionGeneral cognitive ability (or general intelligence; g) has been widely recognized to influence a broad array of cognitive abilities of both humans and mice. Working memory has also become recognized as a strong predictor of g in both humans and mice. Recent evidence suggests that a component of working memory, selective attention, is responsible for the relationship between working memory and g. In three experiments, we test a hypothesis that emerges from human behavioral studies which suggests that attentional disengagement, a component of selective attention, critically mediates its relationship with g, and therefore should be most strongly predictive of general cognitive performance. Experiments 1 and 2 both assess the factor loadings of selective disengagement tasks on a general cognitive factor derived from larger batteries of cognitive tests and finds that selective disengagement loads more highly than any other measures that place less explicit demands on disengagement. In experiment 3 we demonstrate how groups with known differences in cognitive abilities (young vs. old mice) differ significantly on measures of attentional disengagement. Our results provide support for the hypothesis that disengagement acts as the latent variable that determines intelligence.
