Abstract
The experiment explored the relationship between changes in heart rate which accompany exposure to countercommunications and subsequent attitude change. Heart-rate data were recorded while Ss engaged in a structured interview in which they were verbally reinforced for choosing to read aloud statements opposite to their initial attitude. Ss whose net attitude change scores were in the direction of the reinforcement were significantly higher in initial base-line heart rate and degree of heart-rate increase than anticonformers and showed a significant decrease in heart rate during the interview. Anticonformers were lower on all heart-rate measures, showing a maintenance of heart-rate arousal during the session. It was tentatively concluded that attitude change in response to social influence is accompanied by heart-rate decline. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
