The Gf-Gc model (McGrew, 2003; McGrew and Flanagan, 1998) guided the development of most contemporary cognitive ability tests (Kaufman and Kaufman, 2004; Wechsler, 2003), as it enumerates general cognitive ability through the evaluation of its multiple components. This study involved an investigation of the Gf-Gc domains including added attention and executive control domains, which was measured by the Wechsler Intelligence Scale for Children, 4th Edition (WISC-IV) and Conners' Continuous Performance Test, 2nd Edition (CPT-II). These domains were compared via factor analysis of the WISC-IV and CPT-II.
In addition, Structural Equation Modeling was used to test the structure of the Dean-Woodcock Neuropsychology Model (Dean et al., 2003), particularly the primacy of attention and the interaction of executive control with other cognitive skills. The current study provided support for the addition of separate attention (Gat) executive control (Gec) components within a Gf-Gc cognitive model. In addition, a significant interaction was found between attention and processing speed, which supports attention as a primary cognitive skill.
