Click here for other posts in this series.The sheer number of key, review, and individual studies populating the published Flanagan et al. (2006) CHC CB COG-ACH correlates summary tables is impressive. However, the available CHC COG-ACH relations summaries suffer from a number of limitations. First is a lack of descriptive and operational rigor in the CHC COG-ACH syntheses. The Flanagan research group’s efforts appear to fit the definition of a purposeful research synthesis which “focus on empirical studies and seek to summarize past research by drawing overall conclusions from many separate investigations that address related or identical hypotheses” (Coope...

Although the comprehensive CHC COG-ACH relations summary tables are not structured to reflect age-differentiated relations, Flanagan et al. (2006) provide insights into potentially important developmental COG- ACH relations. For example, the Flanagan research group reported that Ga, Gs and Glr abilities are important during the early school years and then decline in relative importance while Gc becomes increasingly important with increasing age. Narrow ability COG-ACH differential developmentally-based relations are also briefly summarized by Flanagan et al. (2006). Despite limited empirical evidence in k...

The closest other effort of note is the blended CHC-neuropsychological research integration efforts of Fiorello and colleagues (Fiorello, Hale & Snyder, 2006; Fiorello & Primerano, 2005; Hale & Fiorello, 2004).According to Flanagan et al. (2006), studies were identified for potential inclusion in their CHC COG-ACH summaries via three search methods. First, research studies that investigated the relations between cognitive abilities and reading, math, and writing achievement were identified via a search of the PsycINFO electronic database.

This meeting resulted in the 1989 publication of the first individually-administered, nationally standardized CHC-based intelligence battery, the Woodcock- Johnson- Revised (Woodcock, McGrew, & Mather, 1989). This landmark event, which occurred 20 years ago, provided the impetus for the major CHC- driven evolution of school- based intelligence testing practice. Subsequent important CHC events followed during this 20 year period, and included: (a) the first set of CHC- organized joi...

Carroll expanded on the Cattell- Horn Gf- Gc theory and proposed a three-stratum model that contains over 70 narrow or specific abilities at stratum one, eight primary second-order abilities at stratum two, and an overall g ability (general intelligence)at stratum three.
