This article provides a general overview of cognitive dissonance research with the induced compliance paradigm. We begin by describiang how dissonance affects individuals' attitude change and address issues related to measurement of attitude. Next, we describe the arousal component of dissonance, how it has been measured and the issues that have been raised about its nature. Finally, we explore the emotional component of dissonance and review different ways for measuring and identifying the negative affect associated to dissonance. We conclude by claiming that a more intensive study of the process of dissonance, and particularly of its arousal and emotional components, will allow a more in-depth understanding of the mental processes involved in cognitive dissonance.
