The relationship between self-described sex roles and two measures of cognitive style (intolerance for ambiguity and level of abstractness-concreteness) were explored. Subjects were 87 male and 204 female college students. The Schroder and Streufert measure of cognitive style, the Budner Intolerance for Ambiguity Scale (1962), and the Bem Sex Role Inventory were utilized. Data were analyzed using two 2x4 analyses of variance. Independent variables were sex and sex role. Dependent variables were cognitive style and tolerance for ambiguity. Findings indicate the following: (1) androgynous and cross-sexed males and females are more tolerant of ambiguity than sex-typed individuals and cognitively more abstract than undifferentiated subjects; (2) cross-sexed subjects are more abstract than sex-typed; and (3) cognitive style and tolerance for ambiguity are better predictors of sex-role than is sex.
