Goals and achievement orientations of anglo and mexican-american adolescents in sport and the classroom

The purpose of this study was to analyze the definitions of success and failure (achievement goals) and preferred means to goal attainment (achievement orientations) among male and female Anglo and Mexican-American high school students I athletes in sport and the classroom. Based on a recent conceptualization of achievement motivation, it was assumed that definitions of success and failure could be equated to personal characteristics, behaviors, or outcomes and reflect an emphasis on either effort or ability. Further, it was assumed that there are two major achievement orientations: In one, the means to goal attainment entail social comparison; in the second, goal attainment is processed according to mastery criteria. Results revealed cultural and sex differences in athletic goals. Anglo males were more likely to define sport success in terms of ability while Anglo females and Mexican-American athletes tended to equate athletic success to the demonstration of effort. The reverse was true for sport failure—Anglo males emphasized low effort while the other groups stressed low ability. Variations in preferred achievement orientations were also revealed. For example, in the athletic setting, females showed the least preference for sport success which reflected on the individual and involved social comparison. Males indicated the least preference for individual-oriented, social comparison-based athletic failure.

The effects of economic development and modernization in resolving traditional-modern attitudinal conflict

Experts point out that development changes societies in ways so profound that they cannot be anticipated by the participants in the experience. This article analyses the effects of rapid economic development on traditional life styles and the resolution of ensuing attitudinal conflict. Previous studies of traditional-modern (T-M) problems encountered in the process of modernization are reviewed and modernization theories and methodological problems are discussed. Evidence is presented for a T-M model based on studies in West Africa, Australian aborigines, Hong Kong Chinese, Japanese, and Alaskan Eskimo, identifying certain independent variables which are held to influence modernization: the nature of traditional ecologies, e.g., agricultural, pastoral, or hunting/fishing societies, the severity of socialization and the nature of traditional authority systems. The analysis confirmed that development does change societies in profound ways, uprooting cultures, altering environments and modifying individuals physically and psychologically. However, it was also postulated, based on T-M research, that hunting, fishing and the main pastoral societies are generally more highly resistant to change, do not want change and may be better off without it. In contrast, most agricultural and mixed agricultural-pastoral societies are not only more susceptible to modern change, they can usually derive the most benefit from it and also in most cases want change.
