Children with SAD may be neglected or overprotected by their families. Empson (2015) stated that the sensitive period (between age 5 and puberty) is when a person is maximally ready to receive environmental stimuli, which is the best time for child development. Children experience different situations in their caregiving environment at critical periods, and they may be vulnerable or resilient in those situations. Early identification and intervention must be implemented for the children who are at risk during the critical period (the period during which children’s achievement and development are at the highest level). Children with social anxiety are often considered as being shy in the classroom. On the one hand, shy children are more likely to be subjected to overprotective parenting which can undermine their autonomy and ability to succeed in developmental challenges (Epson, 2015). On the other hand, there is a clear association between social anxiety and family rejection. The children who are neglected by their parents or with unsecured attachment usually show social and behavioral disorders such as SAD.
