Cattell-Horn-Carroll (CHC) theory of cognitive abilities (v2.5) "official" broad and narrow defilntions

This was first published 7-10-17.  A minor edit to the working memory capacity code (Wc and not WM) was made 7-20-17.


CHC broad and narrow ability definitions (07-20-17)-v 2.5

(Abstracted from: Schneider, W. J., & McGrew, K. S. (in press). The Cattell-Horn-Carroll Theory of Cognitive Abilities. In D. P. Flanagan & Erin M .McDonough (Eds.), Contemporary intellectual assessment: Theories, tests and issues (4th ed.,) New York: Guilford Press.)

Narrow abilities with bold font = major ability; regular font = minor ability.  If all factor codes are regular font under a broad ability = insufficient data to classify as major or minor (Schneider & McGrew, in press).   Italic narrow factor code font designates “tentative” abilities.   Broad ability color codes (as per Ackerman et al.’s PPIK model of intelligence).  Blue – Intelligence-as-process; Gray – Intelligence-as-knowledge; Green – Intelligence-as-Process (speed/fluency); Red = other tentatively identified broad abilities.

 Dr. Joel Schneider and I have recently submitted our new/revised Cattell-Horn-Carroll (CHC) theory chapter for publication in the 4th edition of the Flanagan and Harrison Contemporary intellectual assessment book (see reference above).  Most of the CHC broad and narrow definitions did not change, some changed in minor ways, and others changed significantly.  The rationale for changes will be presented in our chapter when the book is published.  Here I present the abstracted up-to-date definitions.  A PDF copy an be downloaded here.  Be sure to purchase the book when it becomes available to learn more about the changes in some of the definitions and proposed revisions to CHC theory.


Fluid reasoning (Gf): The use of deliberate and controlled procedures (often requiring focused attention) to solve novel “on the spot” problems that cannot be solved by using previously learned habits, schemas, and scripts.

·   Induction (I): The ability to observe a phenomenon and discover the underlying principles or rules that determine its behavior. This ability is also known as rule inference.

Sometimes referred to as spotlight or focal attention, focus, control of attention, executive controlled attention, or executive attention.
·   Working memory capacity (WM):  The ability to manipulate information in primary memory.  Technically not a narrow ability (WMC = short-term storage + AC).

Learning efficiency (Gl):  The ability the ability to learn, store, and consolidate new information over periods of time measured in minutes, hours, days, and years.
