CHAPTER 5 – COHESION
Equifinality = final state can be reached from different paths
Social Cohesion: determined by how much the members like each other & the group itself
Collective Efficacy: members’ shared beliefs tht they can accomplish all the components of their groups tasks efficiently
Group Potency: generalized positive expectation abt the groups chances for success
-High potency groups ten to outperform their less potent counterparts
*Collective Cohesive groups use words like family and words involving ‘we’ to describe their group – higher
collectiveness = higher entitativity
Collective effervescence: sharing of emotional reactions within a group
Group Affective Tone: members emotions and moods become synchronized
Relational Cohesion theory: members develop strong ties to groups that are perceived as sources of positivity
2 PRIMARY FORMS OF COHESION: Task Cohesion and Social Cohesion
Successive Stage Models: groups move through a series of separable stages as they develop
Cyclical Models: groups repeatedly cycle thru phases during their lifetimes, rather then in ordered stages.
5 Stage Model of Group Development:
• Forming (orientation)
• Storming (conflict) – fight or flight
• Norming (structure development)
• Performing (work)
• Adjourning (dissolution/ending)- can be stressful even when planned
Equilibrium Model of group development (Bales): members strive to maintain a balance b/w finishing task & enhancing
quality of interpersonal relationships (back and forth of norming & performing)
Punctuated Equilibrium Models: groups often go thru periods of rapid change (can be triggered by barometric events:
incidents that shift interpersonal dynamics in the group)
*Increases in COHESION associated w/ increases in PERFORMANCE* and is strongest in bona fide groups, correlational
studies, smaller groups, sports teams, & project-focused teams
Cognitive Dissonance:when an individ. holds 2 conflicting cognitions.
Caron’s model of cohesion (4 antecedents):
1. Environmental – ex. social pressures
2. Personal – ex. gender, race, age
3. Leadership – leadership style
4. Team Factors – ex. shared experiences of the group, stability of the group (open vs. closed groups), norms, roles
Dimensions of Perceived Team Cohesion
1. Individual Attraction to the Group Task (ATG) - Member’s feelings about involvement with group task.
2. Individual Attraction to the Group Social (ATG-S) -Regard for acceptance and interaction with the group
3. Group Integration Task (GI-T) - Member’s feelings about achieving group task
4. Group Integration Social (GI-S) - Member’s feelings about the group as a social unit.
