“…The few other studies that have examined associations between type of pre-adoption care and cognitive development have yielded mixed evidence, with some studies finding significant effects of type of pre-adoption care on various domains of cognitive development such as intellectual functioning (Miller, Chan, Comfort, & Tirella, 2005;van Londen, Juffer, & Van IJzendoorn, 2007;Wilson, Weaver, Cradock, & Kuebli, 2008), school achievement (Loman, Wiik, Frenn, Pollak, & Gunnar, 2009) and executive functioning (Bruce, Tarullo, & Gunnar, 2009), and other studies not finding effects (e.g., Katzenstein, LeJeune, & Johnson, 2016;Pollak et al, 2010;Welsh & Viana, 2012). In line with research on the effects of other adverse experiences, these inconsistent findings regarding the impact of type of pre-adoption care may suggest that its effects are not deterministic (Sroufe, Coffino, & Carlson, 2010) nor permanent (Smith et al, 2018). One possible explanation which may explain why some children are more affected by adverse experiences prior to adoption than other children, comes from risk and resilience theory (Masten, 2001;Rutter, 1987).…”
