“…This is because a positive effect of higher SES on executive control functions has been demonstrated as early as infancy (Lawson, Hook, Hackman & Farah, 2016), while low SES has been associated with lower executive control in children, most likely due to reduced access to resources and stimulation (Mezzacappa, 2004; Morton & Harper, 2007; Noble, McCandliss & Farah, 2007; Noble, Norman & Farah, 2005). There is some evidence, however, that bilingual advantages on tasks drawing on inhibitory control are present regardless of SES background (Blom et al, 2014; Calvo & Bialystok, 2014; Engel, Santos & Gathercole, 2008; Engel de Abreu, Puglisi, Cruz-Santos, Befi-Lopes & Martin, 2014). This has resulted in the suggestion that the negative effects of a low SES background and the positive effects of bilingualism may cancel one another out (Blom et al, 2014).…”
