Chapter 12 Flashcards
Group
A collection of individuals who have relations to one another that make them interdependent to some significant degree
Benefits of groups
- Protection from predators
- Specialized jobs
- Defense against other groups
- Assistance in need
- Psychological support
- Efficiency
- Idea generation
Social facilitation
The presence of others improves performance
What does the Fishing study (Triplett 1898) illustrate?
- Social Facilitation
- The children turned the reels faster when they were around other kids doing the same thing
What does the Undergraduate philosophy study (Allport 1920) illustrate
- Participants asked to refute philosophical arguments in five minutes
- Participants provided better refutations if they were alone
*Other instances where presence inhibits learning: Math, Memory, Maze learning
Mere Presence Theory
Presence of others facilitates performance on well-learned tasks but hinders performance on novel or difficult tasks
Dominant response
Response that the person is most likely or used to make
What does the Cockroach Study illustrate?
Cockroaches were placed in simple/complex maze and were shone light to facilitate an escape response. When cockroaches was with others, they did better on the simple maze but worse on complex maze.
*Same results when other cockroaches were just observing in the plexiglass container.
Evaluation Apprehension
People’s concern about how they might appear in the eyes of others
What does the True Alone Changing Study (Markus 1978) Illustrate?
Participants were divided into 3 groups to wait for other participants to arrive: Alone, with experimenter watching, and with a repairman not watching but present.
- The MERE PRESENCE of others is enough for social facilitation — Evaluation apprehension enhances this even further
Why do we do better as a group?
- Leaders and expertise
- Pooled experience
- Idea generation
Social loafing
The tendency to exert less effort when working on a group task in which individual contributions cannot be monitored
- Masked distribution of effort
- Cost vs. Benefit
Groupthink
Faulty thinking that arises when members of cohesive groups are pressured to come to a consensus
Reasons for group think
- Conformity
- Leadership
- Self-censorship
- Pluralistic ignorance
How can we avoid group think?
- Leader impartiality
- Encouraging dissension
- Creating subgroups
- Anonymity
- Devil’s advocate
- Review
- Outside opinions
People tend to make better decisions as a group when:
- The question has a precise, factual answer
- Social loafing can be avoided
- Groupthink is avoided (applies to all types of group decision making, factual or subjective)
