Association Between Laterality Configuration and Intelligence and Neuropsychological Profile

Abstract

Laterality is one of the main manifestations of lateralitation [1]. It is a voluntary, conscious and peripheral function that can be modified through training. It is expressed through the preferential use of the hand, leg, eye and ear [2]. The association between laterality and the cognitive hability or the neuropsychological profile is an issue that creates a lot of uncertainty. Because of that, the main target of this study is to explore the association between the laterality obtained in the tests of homogeneity and lateral preference [3] and the Intelligence Quotient (IQ) obtained in the Weschler intelligence battery for children WISC-IV [4] of a clinical sample of 518 subjects from six to sixteen years old. The obtained results showed that there isn’t a statistically significant difference between the different types of laterality and the CIT, but statistically significant differences were found in the Fluid Reasoning Index, specifically in the test of Cubes in favor of subjects with homogeneous laterality. This implies a possible impact form laterality’s configuration in cognitive development and learning; being a matter of importance to attend it in subjects with learning problems.
