The Chicago Center for the Study of Groups and Organizations (CCSGO), one of eight regional centres of the A.K. Rice Institute in the United States, is committed to advancing the understanding of groups and social systems through scholarship and research as well as through consultation, training and experiential study. Towards fulfilling this commitment, members of CCSGO have collected different kinds of data from members and staffs offive non-residential, weekend group relations conferences in the Tavistock tradition conducted at the University of Chicago Medical Center. This work at the University of Chicago has been developed in close collaboration with Solomon Cytrynbaum at Northwestern University in Evanston, Illinois, whose programme of research on group relations has been conducted for more than ten years in that university's Department of Education and Social Policy. Several doctoral dissertations and published papers have been based on the Northwestern University data. Other doctoral papers and research presentations have analysed portions of the University of Chicago conference data (Bodensieck, 1989; Bradley, 1987; Lipgar, 1989); several more are in preparation. This report describes the research plan at the University of Chicago, the kinds of data being collected, the questions under investigation, and early findings.
