Executive functions refer to the individual capacity of engage in objective oriented behaviors, that is, to carry out autonomous and auto-organized actions, oriented for specific goals. Abilities related to the executive functions overlap the psychological concept of intelligent behavior; however, some studies have revealed inconsistency in the relation between those functions and intelligence. Based on this, the proposed study investigated the relation between executive and non-executive functions with intelligence. Specifically, this study analyzed the difference between groups with medium, higher and much higher intelligence concerning the executive and non-executive functions; possible gender effects over performance in executive, non-executive functions and intelligence; the relation among executive functions, non-executive functions and intelligence; and if the relation between intelligence and executive functions is more evident than the relation between intelligence and non-executive functions as the intelligence level increases. The participants were 120 students, boys and girls at age 15 and 16, attending High School in one public and three private schools in the state of São Paulo. They were divided in three groups which are medium, higher, and much higher intelligence. The material utilized were Raven Progressives Matrices General Scale, Wechsler Intelligence Scale for Children (WISC-III), Computerized Stroop Test, FAS Verbal Fluency Test, Trail Making Test part B, Peabody Picture Vocabulary Test, Pseudowords and Words Repetition Test and Rey Complex Figure Test. Variance and Tukey posthoc analyses revealed significant differences in performance among the groups in the measure of verbal IQ and execution IQ in the WISC-III, verbal fluency, cognitive flexibility, vocabulary and visospatial processing. Student s t-Test evidenced that the girls performance were superior comparing to the boys on the Vocabulary sub-test from WISC-III, while the boys showed superior performance in the Information and Cubes sub-tests from WISC-III and in the selective attention measure evaluated by Stroop comparing to the girls. Pearson s Correlation Analysis evidenced correlations among intelligence, executive and non-executive functions most of them in a low to moderate level confirming literature regarding the executive functions multidimensionality and to the need of differenciating such construct regarding intelligence. There were no evidences that the relation between tests of intelligence and executive functions increases according to the intelligence level. So, this investigation tried to support the comprehension of the relation among executive, non-executive functions and intelligence.
