“…When being placed into more benign environments, however, many children are capable of forming secure attachments to their foster parents (Dozier et al, 2001 ; Stovall-McClough and Dozier, 2004 ; Cole, 2005 ; Oosterman and Schuengel, 2008 ; Ponciano, 2010 ; Jacobsen et al, 2014 , see Caharel et al, 2005 for meta-analytic data). More precisely, attachment security has been found to significantly increase during the first year of placement (Gabler et al, 2014 ; Lang et al, 2016 ). Still, foster children have been found to lack an age-appropriate reticence around strangers, also referred to as disinhibited social engagement (Zeanah et al, 2004 ; Oosterman and Schuengel, 2008 ; Pears et al, 2010 ; Van Den Dries et al, 2012 ; Jonkman et al, 2014 ; Lawler et al, 2014 ), which tends to persist despite improvements in attachment security (Chisholm, 1998 ; Smyke et al, 2002 ; O'Connor et al, 2003 ; Rutter et al, 2007 ; Zimmermann, 2015 ).…”
