Group Development Across Time: Reality or Illusion? Small Group Res 34: 223-241

The purpose of this research was to investigate the relationship between the length of time that work groups had been meeting and the verbal behavior patterns and perceptions of group members about their groups. The verbal behavior patterns and perceptions of 180 members of 26 work groups were examined. Perceptions of 639 people in 88 work groups also were explored. Significant relationships and differences were noted between the length of time that work groups had been meeting and the verbal behavior patterns and perceptions of group members. Specifically, members of groups that had been meeting longer made significantly less dependency and fight statements and significantly more work statements. They also perceived their groups to be functioning at higher stages of group development. The results of this study lent further support to traditional models of group development. Verbal behavior patterns of members vary significantly in groups of different durations. Member perceptions of their group’s development also vary significantly in groups of different durations.
