Salience of initial attitude, magnitude of incentive, and attitude change in a forced compliance paradigm.

To examine the application of interpersonal simulation findings to cognitive dissonance and incentive theories of attitude change in the forced compliance paradigm, 60 Ss were paid 50 cents or $2.50 to write counterattitudinal essays with salient or nonsalient initial attitudes. Findings showed that the larger incentive yielded greater change for salient pretest attitudes but that the smaller incentive led to more change of nonsalient pretest attitudes. Measures of error in attitude recall and a correlational analysis between pretest, posttest, and recalled attitudes were also consistent with Bem's (1967) hypothesis of isomorphism between the attributions of Ss and observers. It is proposed that remaining simulation data reported in the cognitive dissonance/self-perception controversy may identify additional parameters of attitude changes in forced compliance experiments.
