|Abstract: ||One hundred thirty-eight sixth form students, aged 16-17, took tests of vocabulary, mental rotation, and abstract reasoning as markers of Gc, Gv, and Gf and also three working memory tests, one verbal, one spatial, and one numerical (mental counters). Consistent with a number of earlier results, we found that verbal working memory correlated with the vocabulary test and spatial working memory with the mental rotation test, but there was only a weak relationship between these two domains. Performance on the reasoning test was associated most strongly with the mental counters working memory test but was also related to performance on both verbal and spatial tests. Confirmatory factor analysis supported a three-factor solution of these data, with one ability test and one working memory test loading onto each factor. This suggests that although working memory may be partly general, it is also at least in part domain-specific with three of these domains corresponding to Gc, Gv, and Gf.|
