Abstract: In this study, the relationship was explored between the CHC factors of \nintelligence, as measured by the Woodcock-Johnson III Tests of Cognitive Abilities (WJIII- \nCog), and executive functioning, as measured by the Tower Test and Color-Word \nInterference Test from the Delis-Kaplan Executive Function System (D-KEFS). \nParticipants were 64 undergraduate students (female, n = 38; male, n = 26), with a mean \nage of 19.88 years. Results of canonical correlation analysis, including subtests of the \nWJ-III-Cog and scores from the D-KEFS, indicated a significant model with a canonical \ncorrelation value of .57 and a canonical R2 of 0.33. All WJ-III-Cog and D-KEFS variables \nwere associated with their canonical variates. Numbers Reversed from the WJ-III-Cog \nand Color-Word Interference Test Condition 3 (Inhibition) from the D-KEFS had the \nhighest correlations with their canonical variates, implicating these tests as important \ncontributors to the relationship. Linear regression analysis indicated a significant model \nin which Verbal Comprehension, Numbers Reversed, Sound Blending, Visual-Auditory \nLearning, Visual Matching, Spatial Relations, and Concept Formation as predictor \nvariables account for approximately 23.4% of the variance in the Color-Word Interference Test Condition 3 (Inhibition) score. The results overall suggest that despite a \nclear relationship between executive function and cognitive ability, much variance \nbetween the D-KEFS and WJ-III-Cog remains unaccounted for. This study may be \nconsidered an appropriate preliminary analysis of the relationship between intelligence \nand executive functioning using these measures, though future research with additional \npopulations is suggested. These findings have implications for evaluation and \nintervention planning within the educational setting.
