The present chapter discusses a number of new experiments that bear on rather direct derivations from dissonance theory and that are designed to reflect on and add to the evidence presented in the preceding chapters. It is hoped that, together with the evidence described in Chapters 3, 4, and 5, a basis will be provided for an overview of the degree of support for the more direct derivations from the theory. This should allow an assessment of the utility of the theory for predicting behavior in a wide range of situations.
In reviewing the evidence on the manipulation of dissonance through the variation of consonant information, we saw that the data on the effects of rewards and justifications for discrepant commitment are quite consistent with the theory. However, the alternative explanation was raised that the inverse relationship between rewards and attitude change might disappear if rewards were small enough. This alternative
