Chapter 7: Group Structure Flashcards
6 characteristics of group structure
- Size
- Member diversity
- Norms (behavioral expectations)
- Roles (who does what)
- Status (rewards and prestige)
- Cohesiveness (group attractiveness to members)
Group Size
2 – 400 people, 3-20 is the most common size
Members of larger groups report lower satisfaction due to:
o Limited time and energy for developing friendships.
o Higher potential for conflict due to differing viewpoints.
o Reduced verbal participation opportunities.
o Difficulty identifying with group accomplishments.
o Social inhibition increases as group size increases
o Individual contributions harder to recognize in larger group
3 types of tasks
- Additive Tasks
- Disjunctive Tasks
- Conjunctive Tasks
Additive Tasks
Larger groups perform better up to a point, but individual efficiency decreases (building a house)
Performance depends on the sum of individual contributions.
Disjunctive Tasks
Larger groups perform better due to the likelihood of including top performers ((e.g., error detection in coding)
Performance depends on the best member.
Conjunctive Tasks
performance decreases as group size increases because of weak links (assembly-line operations)
Actual Performance =
Potential Performance – Process Losses
Advantages of Diversity
- multiple perspectives
- greater openness to new ideas
- multiple interpretations
- increased creativity
- increased flexibility
- increased problem-solving skills
Disadvantages of Diversity
- ambiguity
- complexity
- confusion
- miscommunication in early stages
- difficulty in reaching a single agreement
Deep diversity
differences in attitudes toward work/goals, harm cohesiveness
Surface diversity
age, gender, race, minimal negative impact or diminishes over time
Group Norms
collective expectations about acceptable behaviors within a group
Why Norms Develop
Provide regularity and predictability, ensuring psychological security and minimal disruption
What Norms Regulate
Important behaviors such as performance and attendance are more strictly regulated than trivial matters like office decoration.
How Norms Develop
Shared beliefs and values form shared attitudes, which in turn create norms, group consensus
