Double forced compliance: a new paradigm in cognitive dissonance theory.

An experiment was conducted with a new paradigm of Festinger's (1957) theory of dissonance. This paradigm was used to test dissonance reduction following two behaviors, rather than just one as in the classic forced compliance paradigm. The first behavior involved refraining from smoking for one evening, and the second, convincing a peer that abstinence from smoking was not difficult. It was hypothesized that the dissonance reduction effect would be greater for a sample of French students who had executed both behaviors than for those who had executed only one. The results supported this hypothesis.
