An "ad hoc" questionnaire was administered to 10 students from each of 10 student groups. Each group's behavior was rated according to its degree of deviation from the established code of conduct for organized campus groups. Demographic and sociometric data was collected, as well as a measurement of the respondents' knowledge about the campus, and a ranking of each organization's stated priority for serving society, education, and campus community, or itself. Results show that organized group behavior is affected by intergroup interactions under certain conditions, namely length of members' time on campus, knowledge of the campus, the range of a group's contacts with other groups, the group's inception date, and the academic major of group members. The direction of extreme organized group behavior, either conventional or aggressive, is determined by the degree of generational conflict and by family background and structure. A reaction to the findings, by a different author, is included. (TL)
