The present study represents an attempt to further delineate the sociological and psychological variables that predispose a student to become an activist of the "new left." A total of 103 students participated in the study, 48 experimental and 55 control subjects. Measures used included a self report, an activism index, a Vietnam opinion Survey, Rokeach's Dogmatism Scale (RDS), Rotter's Internal vs. External (I-E) Scale, an Importance of Activities questionnaire, and Stein's Self-Description Questionnaire. The behavioral criterion for identifying student activists which was confirmed in this study consists of: (1) the degree of involvement with sociopolitical issues, and (2) the degree of rejection of the traditional values and institutional authority of the society. The inferences that can be drawn from this study are in accord with the formulations that characterize other literature. Differences on only three of the replicatory demographic variables reached acceptable levels of statistical significance; religion, major field of study, and prospective occupation. While being expremely opinionated, the activists were not found to be ideologically rigid. Activists also have indicated confidence in their ability to influence others. The anti-institutionalization of activists does not appear to have led to total alienation. (KJ)
