Abstract

This study demonstrates that left and right unilateral facial contractions have similar effects on the expression of ethnic stereotypes as do negative and positive moods induced by more conventional means. Subjects who con tracted the left side of their face (negative mood inducer) were more likely to express negative stereotypes of ethnic groups than were subjects who contracted the right side of their face (positive mood inducer). This parallels previous findings obtained using two standard mood inductions: the Veltens mood induction procedure; and a musical mood induction procedure. Given that unilateral facial contractions manipulate mood without cognitive involvement, this mood induction may have advantages over previously used procedures, the effects of which are subject to cognitive mediation explanations. In addition, these results suggest that, at least for the expression of ethnic stereotypes, mood's influence on cognition does not depend on a cognitive component of mood induction.
