“…In addition to working memory, inhibition as well as cognitive flexibility are closely linked with performance on pre-math and pre-reading tasks, suggesting that in contrast to findings in school-aged children, the three EF components are of equal importance in early childhood (Bull et al, 2008;Clark, Pritchard, & Woodward, 2010;Espy et al, 2004;Roebers et al, 2011;Willoughby et al, 2012). Together with the assumption of a more unitary structure of EF in preschool children, these results support research in which a composite measure of EF has been used and in which strong associations with math and reading achievement have been found (Clark et al, 2010;Welsh, Nix, Blair, Bierman, & Nelson, 2010).…”
