title: Relationships between Cattell-Horn-Carroll (CHC) cognitive abilities and math achievement within a sample of college students with learning disabilities.
abstract: This study examined the relationship between cognitive abilities and math achievement within a sample of college students with learning disabilities (LD). The cognitive abilities were seven areas identified by Stratum II of the Cattell-Horn-Carroll (CHC) theory of cognitive abilities, in addition to the eighth area of Working Memory. Math performance was assessed via math calculation and math reasoning tasks. Instruments include the Woodcock-Johnson III Tests of Cognitive Abilities and Tests of Achievement. Participants were 158 college students with a diagnosed LD in math. Multiple regression analyses found that Processing Speed and Working Memory were related to Math Calculation scores and that Comprehension-Knowledge, Fluid Reasoning, and Working Memory were related to Math Reasoning. Implications for the assessment of math LD in the college populations are discussed.
