Ability as a moderator between cohesiveness and tank crews performance

Research output: Contribution to journalArticlepeer-review


Following a situational design with field active tank crews this study investigates the hypothesis that crew members' ability would moderate the relationship between crew performance and level of cohesiveness. Crews were formed by self-selection following a sociometric procedure where intensity of reciprocity in selection served as a measure of cohesiveness. Crew ability level was determined by the average ability of its members. Performance was defined by the ratings of a superior officer. Significantly, performance was best explained by crew cohesiveness, although the alleged moderating effect of crew ability level on performance was also strongly substantiated. The implications of these findings in the wider context of task-oriented groups is discussed.
