“…Initially stimulated by the work of Campbell and colleagues (Campbell, Pierce, March, Ewing, & Szumowski, 1994;Campbell, Szumowski, Ewing, Gluck, & Breaux, 1982), a growing body of studies have examined ADHD symptoms and behavioral inhibition in preschool children (Berlin, Bohlin, & Rydell, 2003;Marakovitz & Campbell, 1998). The majority of these studies (9/11) have found a significant association between ADHD symptoms and deficient behavioral inhibition (Berlin & Bohlin, 2002;Berlin et al, 2003;Byrne, DeWolfe, & Bawden, 1998;Campbell et al, 1982Campbell et al, , 1994Hughes, Dunn, & White, 1998;Marakovitz & Campbell, 1998;Sonuga-Barke et al, 2002;Sonuga-Barke, Dalen, & Remington, 2003), adding credence to the hypotheses that early behavioral inhibition predicts later ADHD symptoms and may influence the relationship between early and later ADHD symptoms.…”
