“…When examined on a study-by-study basis, findings indicate that young CWS, when compared to young CWNS, are (a) more reactive to environmental stimuli (Wakaba, 1998), (b) more negative in their affect/emotions (Howell et al, 1987; Johnson, Walden, Conture, & Karrass, 2010; Ntourou, Conture, & Walden, 2011), (c) less able to maintain attention and less adaptive to their environment (Anderson, Pellowski, Conture, & Kelly, 2003; Embrechts, Ebben, Franke, & van de Poel, 2000), (d) less able to disengage their attention when required (Bush, 2006) or shift attention (Heitman, Asbjørnsen, & Helland, 2004; Eggers, De Nil, & Van den Bergh, 2010), (e) more likely to exhibit problematic scores on attention scales based on caregiver report (Felsenfeld, van Beijsterveldt, & Boomsma, 2010), (f) less able to ignore changes in irrelevant background stimuli (Schwenk et al, 2007), (g) significantly less efficienct in orienting of attention (Eggers, De Nil, & Van den Bergh, 2012; cf. Johnson, Conture, & Walden, 2012), and (h) lower in inhibitory control, as well as significantly higher in anger/frustration, approach and motor activation (Eggers, De Nil, & Van den Bergh, 2010).…”
