Measures general and specific cognitive functions and is based on the evaluation of Cattell-Horn-Carroll model of cognitive abilities.

• A. WISC
• B. KABC
• C. WJ-COG
• D. WIAT

Answer: (C)

This item tests which cognitive ability battery is explicitly designed to map its subtests to the Cattell-Horn-Carroll (CHC) model, a framework that organizes cognitive skills into broad abilities (like fluid reasoning, crystallized knowledge, working memory, etc.) and many narrower abilities beneath them. The Woodcock-Johnson Tests of Cognitive Abilities are built around this theory, with subtests aligned to CHC constructs and reporting that reflects both broad and specific cognitive abilities. This alignment makes it the most theory-driven choice for assessing a wide range of cognitive functions within the CHC framework.

The other measures serve different purposes or are grounded in other theories. The WISC is primarily an intelligence battery organized around Wechsler indices (verbal, perceptual, working memory, processing speed) rather than a direct CHC hierarchy. The KABC focuses on a different theoretical basis (originally Luria-based neuropsychology), and while later editions incorporate broader theories, it is not the quintessential CHC-mapped instrument. The WIAT assesses achievement in academic skills, not general cognitive abilities or their CHC structure.
