psychology was in "crisis," and interest in research on attitude change in particular was declining. As we write this, we are aware of six new volumes on persuasion that are in press or in preparation and that should appear over the next few years. In retrospect, it is not so surprising that research on attitudes and persuasion would reemerge as a central concern of social psychology. We believe that human feelings, beliefs, and behaviors, whether in the domain of interpersonal relations (e. g. , marriage, aggression), politics (e. g. , voting, revolution), health (e. g. , following a medical regimen), or economics (e. g. , consumer purchases) are greatly influenced by the evaluations people have of other people, objects, and issues. Furthermore, evaluations (attitudes) are influenced by affect, cognition, and behavior.
