Important

• Four Characteristics of Cohesion – Cohesion is dynamic (it can change over time), multidimensional (many factors hold groups together), instrumental (groups form for a specific purpose), and affective (strong emotional ties and social relationships exist among members).
• Independence of Task and Social Cohesion – Task and social cohesion often move in the same direction but can be independent. Teams can achieve the highest levels of competitive success (high task cohesion) even if members dislike each other personally (low social cohesion), as seen with the Kobe Bryant and Shaquille O’Neal Lakers.
• The Cohesion-Performance Relationship – The relationship between cohesion and performance is moderately to strongly positive, and it is bi-directional (i.e., high cohesion leads to success, and the “halo effect” of success leads to higher cohesion). This relationship is stronger for task cohesion than social cohesion, and more pronounced in interactive sports (e.g., hockey, basketball) compared to coactive sports (e.g., golf, track).
• Requirements for Successful Role Performance – For a team to function optimally, athletes must possess role clarity (understanding the scope of responsibilities, necessary behaviors, evaluation criteria, and consequences) and role acceptance (which is fostered by minimizing status differences between stars and role players).
• Social Cohesion Drives Adherence – While task cohesion is the stronger predictor of performance, social cohesion is a very strong predictor of an athlete’s intention to return and participate in the future, particularly in youth and recreational sports.
• Cohesion Combats Social Loafing and Self-Handicapping – High team cohesion makes social loafing (hiding in the crowd and reducing effort) less likely, as players believe their efforts truly matter. It is also negatively associated with self-handicapping (creating excuses to protect self-esteem).
• Team Building as an Indirect Intervention – Effective team-building in sport often utilizes an indirect approach where a sport psychologist teaches the principles to the coach or exercise leader, who then implements the strategies directly with the group.
• Hazings vs. Cohesion – Hazing and bullying compromise physical and psychological well-being and are detrimental to team functioning. They lower cohesion and should not be confused with positive team-building norms or initiations.

Core Concepts

• Group Dynamics: The study of the nature of groups and their development, and the interrelationships of groups with individuals, other groups, and larger institutions.
• Group Cohesion: A dynamic process reflected in the tendency for a group to stick together and remain united in the pursuit of its instrumental objectives and/or for the satisfaction of member affective needs.
• Task Cohesion: The degree to which members of a group work together to achieve specific and identifiable goals.
• Social Cohesion: The degree to which members of a team like each other and enjoy a personal satisfaction from being members of the team.
• Group Integration: A member’s perceptions of the group or team as a whole (e.g., “Our team is united…”).
• Individual Attractions to the Group: A member’s personal attraction to the team (e.g., “I like this team’s style of play”).
• Formal Roles: Specific roles explicitly set out by the group or organization, such as coach, captain, point guard, or defensive specialist.
• Informal Roles: Roles that evolve naturally as a result of the interactions that take place among group members over time, such as the team mediator, social director, or team clown/joker.
• Role Ambiguity: A lack of clear, consistent information regarding an individual’s role, which can compromise team cohesion and performance.
• Norms: Formal or informal standards of behavior expected of members of the group (e.g., dress codes, effort in practice).
• Social Loafing: The reduction in individual effort when individuals work collectively compared to when they work alone.
• Groupthink: A mode of thinking that people engage in when the members of a cohesive group so strongly desire a unanimous decision that it overrides their motivation to realistically evaluate other possible options.

Theories and Frameworks

• Conceptual Model of Group Cohesion: Developed by Carron, Widmeyer, and Brawley, this model portrays cohesion as a multidimensional construct that includes individual and group aspects, both of which divide into task and social dimensions. It serves as the foundation for the Group Environment Questionnaire (GEQ), which assesses four dimensions: Group Integration-Task (GIT), Group Integration-Social (GIS), Individual Attractions to Group-Task (ATGT), and Individual Attractions to Group-Social (ATGS).
• Correlates of Cohesion Framework: A model illustrating the bi-directional factors associated with cohesion:
  • Environmental Factors: Proximity (sharing space/traveling together) and Distinctiveness (uniforms, logos, team slogans).
  • Personal Factors: Individual satisfaction, competitive state anxiety, social loafing, adherence, and sacrifice behaviors.
  • Leadership Factors: Leader behavior (training/instruction, social support, positive feedback) and decision style (democratic vs. autocratic).
  • Team Factors: Enhanced performance, collective efficacy, and psychological momentum.
• Team-Building Program Model (Carron & Spink): An indirect four-stage model for implementing team building:
  1. Introduction: Leaders learn about the benefits of cohesion.
  2. Conceptual: Leaders are introduced to a framework (inputs, throughputs, outputs) identifying factors like distinctiveness and group norms.
  3. Practical: Leaders actively brainstorm specific, practical strategies to use with their groups.
  4. Intervention: Leaders take the developed protocols and implement them into their specific team or exercise settings.
• Tuckman’s Group Development Model: A framework detailing the stages of group evolution (forming, storming, norming, performing) as team members transition from individuals to a unified unit.

Notable Individuals

• Albert Carron: Prominent Canadian sport psychologist who developed the modern definition of cohesion and the Conceptual Model of Team Cohesion.
• Neil Widmeyer & Larry Brawley: Co-developers (with Carron) of the Conceptual Model of Team Cohesion and the Group Environment Questionnaire (GEQ).
• Kevin Spink: Contributed heavily to team-building models in sport and exercise settings, specifically developing the indirect four-stage team-building protocol with Carron.
• Pat Summitt: Legendary basketball coach who likened the blending of disparate personalities to form a team to assembling a jigsaw puzzle.
