On the other hand, cross-cultural studies conducted in the United States, Canada, and Mexico by Richmond and Millar (1984), and in Canada, Japan, and the United States by Richmond, Sukemune, Ohmoto, Kawamoto, and Hamazaki (1984) indicated that sex was not related to levels of anxiety among students in elementary schools.Early studies (Combs, 1964;Dyson, 1967;Fink, 1962;Sears, 1970) performed on the relationship between the self-concepts and academic achievement of students in the United States showed that a positive relationship
