This study focused on the worldminded attitudes of Japanese college students in Japan and in the United States. The effects of studying abroad and the change in attitudes between Japanese college male students and female students were examined in terms of worldmindedness, which is defined as a frame of reference, or value orientation, favoring a worldview of the problems of humanity, with mankind rather than nationals of a particular country as the primary reference group. In this study worldminded attitudes are defined as attitudes about religion, immigration, government, economics, patriotism, race, education and war. This study tested the hypotheses that worldmindedness scores would increase as a result of the study program in the United States, and that Japanese women would score higher worldmindedness scores than would Japanese men. The data were collected from Japanese students who studied at Oregon State University for five months, and those who had not studied abroad before. The results revealed that woridmindedness scores increased as a result of the study in the United States, supporting the first hypothesis. While female students began their foreign study significantly more worldminded than their male counterparts, only the males changed significantly. Paradoxically, the females who did not study abroad scored more worilmindedness than the females who did. However, the sample size for females was very small (N=18). Generalizations drawn from the experimental group data are limited by the low completion rate: the data were collected during the last two weeks of a five-month period at Oregon State University, and only 40 percent of the questionnaire were completed. Therefore, those who had adopted more worldminded position might have been over represented. A replication of the study could insure against partial data. Also, it would be important to know if Japanese students revert back to their less worldminded views after returning to Japan. Longitudinal studies could resolve this issue. / Graduation date: 1991
