Groups and Group Cohesion File Flashcards
Definition of a Group:
A group is two or more people who interact directly, are aware of their interdependence, and work together to achieve a shared goal.
Seven Characteristics of a Group (Johnson & Johnson, 2009):
Two or more people who perceive themselves as members.
Direct interaction between members.
Structured interaction through roles and norms.
Members are interdependent.
Members influence each other.
Group members share a common goal.
Membership satisfies a personal need for belonging or achievement.
Definition of a Team:
A team is a specific type of group, where members not only work together but also share a common goal and depend on each other’s success for the achievement of that goal.
Difference Between a Team and a Group:
Group:A collection of individuals who may or may not work collaboratively or share a common goal
Team:A group that is organized, with defined roles, interdependence, and a clear objective
Key Characteristics of a Team:
Common Purpose:All members work toward the same goal.
Interdependence:Team members rely on each other’s performance for success.
Role Differentiation:Each member has a specific role that contributes to the overall objective.
Mutual Accountability:Team members hold each other accountable for the group’s performance.
Cohesion:Team members share a sense of unity and commitment to the team’s goals.
Definition of Group Dynamics:
A field of inquiry in social psychology focused on understanding the nature of groups, their development, and their relationships with individuals and larger institutions.
Essentially, group dynamics examines how groups behave internally (among members) and externally (with nonmembers).
Why Study Group Dynamics?
Groups are a significant part of our daily lives, influencing us in many ways.
Understanding group dynamics helps us improve group performance and relationships.
Group dynamics are studied across various fields: political science, business, psychology, and more.
Group Composition:
The individuals within a group affect how the group behaves and performs.
Assembly Effect:
Variations in group behavior occur based on the particular combination of individuals in the group.
The way a group behaves depends on who is in the group.
Rosenberg (1955) found that individuals contributed differently depending on who they were grouped with.
Steiner’s Model of Group Effectiveness:
Actual Productivity = Potential Productivity – Process Losses
Potential Productivity:
The best possible performance based on group resources.
Process Losses
Inefficiencies that reduce performance, such as poor coordination or reduced motivation.
Sources of Process Losses:
Faulty Coordination: Difficulty in synchronizing efforts among team members.
Reduced Motivation: Individuals may not put in maximum effort when working in a group.
Group Effectiveness:
A group’s effectiveness is determined by the balance between group resources and process losses.
Team A vs. Team B Example:
Team A will be more effective than Team B if:
It possesses greater relevant resources and experiences fewer process losses.
It possesses greater relevant resources but experiences approximately equal process losses.
It possesses approximately equal relevant resources but experiences fewer process losses.
Four Types of Group Tasks (Steiner, 1972):
Additive Tasks:
Compensatory Tasks:
Disjunctive Tasks:
Conjunctive Tasks:
Additive Tasks:
Group performance is the sum of individual efforts (e.g., team relay in swimming).
Compensatory Tasks:
Group performance is an average of individual efforts (e.g., scoring in gymnastics).
Disjunctive Tasks:
Group performance depends on the strongest member (e.g., a lead cyclist in a cycling race).
Conjunctive Tasks:
Group performance depends on the weakest member (e.g., a rowing team).
Social loafing, Definition
Social loafing refers to the reduction of individual effort in a group setting compared to when working alone.
Occurs when individual contributions are less identifiable.
More likely in large groups or in tasks where individuals feel their contribution is dispensable.
The Ringlemann Effect definition
The Ringelmann Effect refers to the phenomenon where individual effort decreases as group size increases.
Max Ringelmann’s research in the 1880s found that as more people were added to a task (e.g., pulling a rope), the overall effort per person decreased.
The Ringlemann Key Findings:
Performance loss is due to bothcoordination losses(difficulty in synchronizing actions) andmotivation losses(individuals feeling less accountable in larger groups).
The larger the group, the more people assume others will pick up the slack, leading to reduced individual effort.
Closely related tosocial loafing, but emphasizes group size as a factor.
The Köhler Effect
Occurs when weaker members of a group increase their effort because they feel indispensable.
Most common in conjunctive tasks where group performance depends on the weakest member.
