Self-concepts of adolescents in Germany, Mexico, Chinese in Taiwan, and the U.S.A. were measured with an Osgood type of semantic differential. The American sample included Anglo, Chicano, and Indian high school seniors. The 11 concepts included: attitudinal measures on the self, school, social milieu and other racial groups. The bipolar adjectives comprised: good-bad, sharp-dull, ugly-beautiful, strong-weak, slow-fast, shallow-deep, effective-ineffective, valuable-worthless, intelligent-stupid, and honest-dishonest. Tests were translated into Chinese, German, and Spanish; effort was made to preserve semantic equivalence. In perceptions of self, the German mean was lowest, and the Mexican mean was highest. This pattern was repeated in perception of school. Perception of the social milieu showed that Anglos were lowest; the Mexican mean was highest. Perceptions of other groups was highest in the Mexican group; the Chinese students were low. Based upon an overall assessment, it was found that Mexican adolescents gave the most favorable perceptions, followed by Chicanos, Chinese, American Indians, Germans and Anglos at the bottom with the least favorable perceptions.
