Based on the self-generated attitude change model, a process constraint treatment analogue was investigated. Differential treatment effects were explored for people that are verbalizers and visualizers. It was predicted that people who participated in the process constraint condition would benefit more if they were verbalizers than visualizers. It was also predicted that there would be no difference in effects for people in the control condition. To test these predictions, people with a fear of speaking in public were asked to speak in front of a small group. The effects of the treatment conditions were assessed using self-report, behavioral, and physiological measures of fear. Results supported the predictions on the behavioral and physiological measures, but only in part on the self-report measures. Implications of these results are discussed as well as directions for future research.
