title: Hostility and facial expression in young men and women: is social regulation more important than negative affect?
abstract: Behavioral differences may clarify the link between hostility and health. This study examined facial expression. Seventy-two low- and high-hostile undergraduates underwent the Type A Structured Interview (SI) and a test of social anxiety. Facial behavior was measured with the Facial Action Coding System. Low-hostile participants displayed non-Duchenne smiles more frequently than high-hostile participants during the SI. There were no group differences in the expression of disgust. The results identify differences in the nonverbal behavior of hostile people. Restricted use of non-Duchenne smiles may reflect limited use of appeasement, contributing to uncomfortable interpersonal relations and limited social support. The findings are consistent with a behavioral ecology perspective and suggest that social regulation may be as important as negative affect in determining the consequences of hostility.
