“…Within a devel-opmental and transactional framework, this biologically based wariness when exposed to unfamiliar people, situations, and activities (Fox, Henderson, Marshall, Nichols, & Ghera, 2005) can be understood as an antecedent of anxious withdrawal (AW), that is, self-imposed isolation in the company of peers (Rubin, Coplan, & Bowker, 2009). When displaying high and stable BI and AW across time, children have been found to be at greater risk of developing later anxiety disorders (Chronis-Tuscano et al, 2009), to be less socially competent than children of similar ages, and, thus, more vulnerable to peer exclusion, rejection, and victimization (Rubin, Barstead, Smith & Bowker, 2018). Nevertheless, Chronis-Tuscano and colleagues (2009) have shown that only one third of highly inhibited children during early childhood developed an anxiety disorder during adolescence.…”
