48 female college students, selected to be relatively high or low on Rokeach's Dogmatism scale, listened to a series of tape-recorded statements asserting opinions that were either in strong agreement, strong disagreement, or mild disagreement with attitudes common in their group. Changes in galvanic skin responses were measured for each of 12 statements, 4 items representing each agreement condition. GSRs were greater for strong disagreement than strong agreement and for strong agreement than mild disagreement. Analysis of variance of the transformed GSR scores showed significant effects of level of dogmatism and extent of disagreement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
