“…For example, Moran, Lengua, and Zalewski (2013) found
that, among 36–40-month-olds, the frequency and intensity of fear or
frustration were positively related to externalizing symptoms for children with
low and/or moderate –but not high– effortful control. However,
the interaction between anger/frustration or negative emotion and effortful
control did not predict social skills (which are related to, but not the same
as, peer-nominated acceptance; Moran et al,
2013) or prosocial behaviors (reported by mothers/teachers; Rydell, Berlin, & Bohlin, 2003). Furthermore, Belsky, Friedman, and Hsieh
(2001) found that among 15- to 36-month-olds, negative emotionality
negatively predicted social competence (e.g., empathy, cooperation) only for
children low in regulation (i.e., attention focusing/shifting).…”
