“…During early childhood, boys perform less well than girls on multiple cognitive dimensions, including attention and executive functions such as working memory and inhibitory control (Berlin & Bohlin, 2002;Carlson & Moses, 2001;Vuontela et al, 2003). Boys are also more vulnerable to-that is, they exhibit more behavioral problems in response to-the effects of the early social environment (Kraemer, 2000), including family effects such as divorce, marital discord, and maternal depression (Cooper, Osborne, Beck, & McLanahan, 2011;Rutter, 1971;Turney, 2011). Finally, boys are more vulnerable to parenting typified by coercion, lack of affection, and lack of monitoring in relation to later aggression, substance abuse, and delinquency (Griffin, Botvin, Scheier, Diaz, & Miller, 2000;McFadyen-Ketchum, Bates, Dodge, & Pettit, 1996), outcomes associated with childhood deficits in inhibitory control (Ivanov, Schulz, London, & Newcorn, 2008;Kerr, Tremblay, Pagani, & Vitaro, 1997).…”
