The purpose of this study was to investigate the effect of the evaluative characteristics of forewarning on persuasion and its mediating processes. We manipulated forewarning by providing pre-message information about the topic and position (TP-type forewarning), or the topic only (TO-type forewarning) of the upcoming persuasive communication. Five kinds of forewarning conditions were used: three TP-type forewarnings with positive, negative, and neutral evaluative characteristics, one TO-type forewarning with neutral evaluative characteristics, and one condition with no forewarning. Subjects in the experimental conditions were either forewarned or not forewarned before the presentation of the persuasive communication. Subjects in the control conhtion, however, were exposed to neither forewarning nor persuasive communication. Results showed that the presence of forewarning &d not produce resistance to persuasion, but that the TP-type forewarning with negative evaluative characteristics produced more counterarguments and psychological reactance in the period between forewarning and persuasive communication than the TO-type forewarning with neutral evaluative characteristics.
