ARAN-FILIPPETTI, Vanessa; KRUMM, Gabriela L.  and  RAIMONDI, Waldina. Executive functions and its correlates with crystallized and fluid intelligence: a study in children and adolescents. Neuropsicologia Latinoamericana [online]. 2015, vol.7, n.2, pp. 24-33. ISSN 2075-9479.

The present study examines the relationship between intellectual abilities (i.e., Gc = crystallized intelligence and Gf = fluid intelligence) and Executive Functions (EF) (i.e., working memory, inhibition, cognitive flexibility, planning, and verbal and nonverbal fluency) in a sample of 214 children and adolescents divided into two groups according to age: (a) 7 to 10 years old and (b) 11 to 15 years old. In addition, the differences in EF task performance according to the level of General Intelligence (GI) (i.e., MB: medium low, M: medium, MA: medium high) are analyzed. In the children's sample, the results revealed low correlations in the range from .22 to .39, between intellectual skills and some EF. However, in the sample of adolescents, low to moderate correlations between intellectual abilities and all the EF analyzed were found. Likewise, MANOVA results revealed significant differences according to the GI's level of the adolescents, in most of the EF analyzed. The results support the hypothesis that sustains that both, Gf and Gc, are associated with the different components of the EF construct, although this association would be selective and with differences according to the stage of the evolutionary development.
