Problem: How can I make notes with bullet points in this paragraph? As in other areas of development, temperament interacts with experience to pre dict peer status. Children are more likely to be rejected by their peers if they are exposed to high levels of conflict between their parents and have a temperament that is low in effortful control (David & Murphy, 2007). They are more likely to become socially withdrawn if their mothers are negative and they have a shy tem perament (Hane et al., 2008). Some behaviors related to peer interactions may even map onto neural-based sys tems; namely, the Behavioral Activation System (BAS) and the Behavioral Inhibition System (BIS). Children high on BAS tend to approach peers and social interactions, whereas children high on BIS tend to avoid peers and social interactions. Research indicates that socially competent children who interact well with peers tend to be high on BAS and low on BIS (Kingsbury et al., 2013). Evidence that peer status has biological underpinnings has also been shown in studies of children's hormone lev els (lower levels of trait cortisol are associated with poor-quality peer relationships; Booth et al., 2008) and heart rate (better regulation of heart rate is related to higher peer status; Graziano et al., 2007).
