The purpose of this study was to determine the impact of an introductory college psychology course on student attitudes, specifically social liberalism. A 30-item true/false test instrument, developed at Michigan State University and purported to measure student attitudes on a dimension of liberalism-conservatism, was used in the studies. Data were gathered from a pretest and posttest administered to a matched group of 54 community college students enrolled in an introductory psychology course. The findings showed a significant change in attitudes of social-liberalism between the administration of the pre- and posttests, with the direction of change toward accentuating liberalism. The author specifies four limitations of the study which prevented a precise identification of causal factors which might account for such a significant change in student attitudes.
