Motivational influences on compliance with and consequences of instructions to suppress stereotypes

Two experiments investigated differences in compliance with instructions to suppress stereotypes as a function of prejudice-related motivations. In Experiment 1, only participants identified as high in motivation to control prejudice [Dunton, B. C., & Fazio, R. H. (1997). An individual difference measure of motivation to control prejudiced reactions. Personality and Social Psychology Bulletin, 23, 316–326] complied with suppression instructions. These participants experienced post-suppression rebound effects, but only if they were also high in prejudice. In Experiment 2, only participants identified as high in external motivation to respond without prejudice [Plant, E. A., & Devine, P. G. (1998). Internal and external motivation to respond without prejudice. Journal of Personality and Social Psychology, 75, 811–832] complied with instructions to suppress. These participants later experienced stereotype rebound effects, but only if they were also low in internal motivation to respond without prejudice. These findings suggest that motivational factors play an important role in determining not only the outcome of suppression, but also the choice to attempt suppression in the first place.
