The purpose of this study was to examine the contribution that social goal orientations and moral atmosphere make toward understanding moral functioning. Participants were 100 female high school basketball players. They completed questionnaires assessing three-dimension goal orientations, moral atmosphere, and moral functioning. Results from hierarchical multiple regression analyses indicated that: 1. The moral atmosphere could predict the moral functioning. 2. There were significant interactions between an individual’s social goal orientation and the team moral atmosphere for moral judgement and behavior. These results suggested that considering both social goals and team atmosphere may explain moral functioning in sport more fully. Coach could promote the athletes' social orientation and positive team moral atmosphere.
