Relationships between cohesion, collective efficacy and performance in professional basketball teams: an examination of mediating effects.

Abstract The main aim of this study was to examine mediating effects in the relationships between cohesion, collective efficacy and performance in professional basketball teams. A secondary aim was to examine the correlates of collective efficacy in a professional sport. A total of 154 French and foreign professional players completed French or English versions of questionnaires about cohesion and collective efficacy. Two composite measures of individual performance were used (pre- and post-performance). Individual-level analyses were performed. Regression analyses supported two mediating relationships with collective efficacy as a mediator of the pre-performance – Group integration-task relationship, and Group integration-task as a mediator of the pre-performance – collective efficacy relationship. Statistical analyses indicated that neither Group integration-task nor collective efficacy was a better mediator in the relationship between pre-performance and the other group variables. Results also revealed positive relationships between three dimensions of cohesion (i.e. Individual attractions to the group-task, Group integration-task, Group integration-social) and collective efficacy. These findings suggest that in professional basketball teams, staff members should look after athletes who perform at a lower or below their usual level because their performances might lead them into a downward cohesion – collective efficacy spiral. Staff members should also develop a high quality of group functioning, both on and off the basketball court, given its relationship with collective efficacy.

Decision-Making during Games by Professional Handball Coaches Using Regulatory Focus Theory

The main goal of this study, based on regulatory focus theory, is to assess the effects of the reward structure on the defensive strategy of handball teams. The results show that (a) a promotional defensive strategy is more often preferred in the second half of the second half-time than in any other game period and (b) second-division coaches are more likely to put their players in regulatory fit situations than are first-division coaches, and could, thus, be more influenced by affordance situations than first-division coaches, who would be more concerned with the ratio of strength between the teams.

External Influences on Referees’ Decisions in Judo: The Effects of Coaches’ Exclamations During Throw Situations

The present research investigated the influence of coaches’ exclamations on referees’ decision-making in judo. Under time pressure, 65 judo referees judged identical throw situations played on video. The coaches’ exclamations during throws were audible in the experimental condition, whereas no sound was present in the control condition. The throw situations varied in ambiguity (low vs. high) and strength (minor sanctions vs. hard sanctions), while coaches’ exclamations interpreted the throws in a manner that was congenial for their own competitor. Results indicated that referees may use an audience response heuristic or a consensus heuristic to help them make decisions.
