On the basis of the widespread belief that emotions underpin psycholog
ical adjustment, the authors tested 3 predicted relations between exte
rnalizing problems and anger, internalizing problems and fear and sadn
ess, and the absence of externalizing problems and social-moral emotio
n (embarrassment). Seventy adolescent boys were classified into 1 of 4
comparison groups on the basis ofteacher reports using a behavior pro
blem checklist: internalizers, externalizers, mixed (both internalizer
s and externalizers), and nondisordered boys. The authors coded the fa
cial expressions of emotion shown by the boys during a structured soci
al interaction. Results supported the 3 hypotheses: (a) Externalizing
adolescents showed increased facial expressions of anger, (b) on 1 mea
sure internalizing adolescents showed increased facial expressions of
fear, and (c) the absence of externalizing problems (or nondisordered
classification) was related to increased displays of embarrassment. Di
scussion focused on the relations of these findings to hypotheses conc
erning the role of impulse control in antisocial behavior.
