Gc as higher order factor including other knowledge systems (verbal, Gq, Grw, Gkn, etc).

Interesting new study that provides some support for our (Schneider & McGrew, 2012 - largely the brilliance of Joel Schneider) conceptualization of Gc as a higher stratum factor, consistent with Cattell's provincial power gc, that includes language/verbal abilities, reading abilities (Grw), quantitative knowledge (Gq), domain-specific knowledge (Gkn), and possible other sources of knowledge. Our figure is at the end of this post. Click on images to enlarge.
