“…We now have indications of a number of possible influences on the early development of CU traits, including low face preference (Bedford et al, 2015), low positive parenting (in particular, low sensitive responding, particularly to distress and low warmth; Wright et al, 2018), increased harsh parenting (Wagner et al, 2019), both higher (Mills-Koonce et al, 2015; Wagner et al, 2019) and lower (Willoughby et al, 2011; Waller et al, 2016) physiological and emotional reactivity, and now potentially female-specific prenatal glucocorticoid mediated influences. However, we do not yet understand whether these factors all contribute independently or in interaction and which are sex-dependant.…”
