A storm closes a community theatre group's usual rehearsal hall. Its 12 members move to a temporary hall, where they rehearse for a play over 16 weeks. A psychologist carries out a case study of the group. She observes one two-hour rehearsal at five points and records cooperative actions using the same behavioural categories each time. The members also keep weekly diaries and take part in unstructured interviews at the end of the investigation.
