Abstract: | Milgram's “small world” method was modified to trace communication patterns in an international student dormitory containing 500 residents from 38 different countries. Eighteen residents served as “starters” for chain-booklets that circulated through the dormitory from friend to friend. Social networks were inferred from the circulation pattern of booklets. Sixteen chains progressed beyond their respective starters, and a total of 86 transactions were recorded. Four determinants of social relations were investigated: culture similarity, sex, organizational affiliation, and residential propinquity. The circulation pattern of the booklets showed that culture similarity was a major determinant of social interaction among the residents. The other main determinant was sex similarity. Organizational affiliation was less important, and proximity played only a minor role in determining communication patterns in the dormitory. |
