Damned if you do, damned if you don't: The differential effect of expression and inhibition of anger on cardiovascular recovery in Black and White males

Appropriate regulation of emotions is an important component of health. The physiological effects of coping with anger are a topic of particular interest. In a pioneering series of studies Hokanson found that the mode of anger expression following anger instigation had differential effects on vascular recovery. These differential effects were thought to be a result of social learning of avoidance responses. The present study examined this hypothesis in the context of ethnic differences in cardiovascular recovery responses to anger instigation. Twenty-four African American (AA) and 26 European American (EA) males engaged in two debates, one racially themed and one non-racially themed, with an EA confederate. Cardiovascular measures were recorded at baseline, during the debates and during 10-minute recovery periods following each debate. Anger expression preceding the recovery period was manipulated such that half the participants could express their anger toward the confederate and half had to inhibit their anger toward the confederate. Results showed that both AA and EA participants that inhibited their anger had delayed total peripheral resistance recovery. Importantly, for the other dependent variables differential recovery responses were observed such that EA participants that expressed their anger recovered more quickly whereas AA participants that expressed their anger recovered more slowly. These results are consistent with Hokanson's social learning theory of recovery from anger instigation and have important implications for research on emotion regulation and health.
