Preschool child and adult lateralisation and performance in emotion and language tasks

Abstract

A total of 34 undergraduate students from the University of Alabama and 34 preschool children completed measures assessing lateralisation and competency in emotion and language processing in order to examine the developmental time course of the underlying lateralised processes. Results indicate different developmental time courses for lateralisation in dichotic words and chimeric faces tasks, and provide some support for the developmental models of Boles, Barth, and Merrill (2008) concerning the relationship between lateralisation and performance.
