Genetics and General Cognitive Ability (G)


Genetics and General Cognitive Ability (G)

Robert Plomin et al. Trends Cogn Sci.


Two recent articles in this journal made the case for the existence and importance of g and reviewed research on cognitive and psychophysical correlates of psychometric g. This review considers g from a genetic perspective. Multivariate genetic research indicates that g accounts for nearly all of the genetic variance of diverse psychometric cognitive tests (genetic g). Recent research suggests not only that elementary cognitive tasks are genetically linked to psychometric g but also that genetic g pervades these tasks. Contrary to the assumption of modularity that dominates cognitive science, genetic g exists in the mind as well as in psychometric tests.
