A study of 1,500 college students was conducted to determine the effect of sex role attitude and cognitive style on the career decision-making of college men and women. An overlapping longitudinal design (which allowed the study of undergraduates at one-year intervals), selected personal interviews, and five measures of sex-role attitude, cognitive complexity, and career choice comprised the methodology and design of the study. Results indicate that gender and sex role attitudes continue to restrict student career options. Selected results of the study are that (1) beliefs about the role-appropriate behavior of others (especially women) precedes and determines one's sex role concept; (2) feminine related sex-role attitudes and degree of cognitive complexity regarding female dominant career choices also predicted gender dominant choices; and (3) personality characteristics associated with each occupational type on the Holland Vocational Preference Inventory do not always apply to both men and women. Interview results showed that instructors or courses were the most significant influence on persons who had changed their career decisions and that work-related field experience generally resulted in being less optimistic about one's future.
