Cattell-Horn-Carroll broad cognitive ability profiles of low math achievers


This study extends previous research examining the relations between Cattell-Horn-Carroll cognitive abilities and math achievement. The cognitive profiles of children with normative weaknesses in Math Calculation Skills or Math Reasoning were compared to those of their average-achieving peers. The cognitive profile of the low Math Calculation Skills group (n = 68) was similar to that of their average-achieving peers. The low Math Reasoning group (n = 52) scored lower than their average-achieving peers on the cognitive abilities as a set and on Fluid Reasoning and Comprehension-Knowledge. When individual profiles were considered, approximately half of the children with normative math weaknesses demonstrated commensurate weaknesses in one or more cognitive abilities, which may inform diagnostic models of learning disabilities. © 2005 Wiley Periodicals, Inc.
