“…Overall, self-regulation, including crying, feeding, and sleeping problems, and inhibitory control in infancy and toddlerhood have been identified as precursors of impulsivity and inattention, which in turn may lead to more severe problems such as attention deficit hyperactivity disorder (ADHD), conduct disorder, learning difficulties, and social exclusion (Campbell & von Stauffenberg, 2009;Olson et al, 2002;Sullivan et al, 2015). These associations have also been found in neurologically at-risk populations, that is, preterm children, with inhibitory control predicting ADHD symptoms in childhood (Jaekel, Eryigit-Madzwamuse, & Wolke, 2016;Poehlmann-Tynan et al, 2015;Reveillon, Tolsa, Monnier, Huppi, & Barisnikov, 2016;Witt et al, 2014) and preadolescence (Reveillon et al, 2016). Accordingly, studies investigating the association between early self-regulation and later attention difficulties need to also control for effects of prematurity.…”
