| Abstract: | Multidimensional attitude change models propose that (1) stimuli defining the domain of attitudes may consist of a multidimensional rather than unidimensional pattern; (2) stimuli associated with each other in the persuasion process will converge with each other in the multidimensional attitude domain. These two propositions receive clear support from three of the hypotheses tested in four-panel cohort data, which analyses show to be multidimensional. The sources of a persuasive message converge on the position they advocate. Multiple sources converge on each other. The findings provided partial support for two other hypotheses on the convergence of self-concept with advocated position and with sources of a persuasive message. A final, somewhat tangential hypothesis also receives clear support: existential associations of concepts are more effective than hortatory associations. These results support further development of multidimensional attitude change models. |
