Week 3 Flashcards
what does this refer to: Even if no member has the right answer, by sharing the unique
information different members have, the group can figure out the
correct answer
Process Gain
Hidden profile tasks
The correct solution is initially hidden from group members and can only
be detected if group members exchange their unshared information
epistemic motivation vs social motivation
epistemic motivation: you want to reach an accurate understanding of the world
social motivation: proself vs prosocial
social motivation is going to affect (3 parts)
- information search and processing
- information sharing
- idea generation and problems solving
epistemic motivation is going to affect (3 things)
- group reliance on decision heuristics
- group centeredness
- idea generation and problem solving
social motivation x epistemic motivation
Proself SM & Low EM
Proself SM & High EM
Prosocial SM & Low EM
Prosocial SM & High EM
Proself SM & Low EM:
- Vetoing
- Indecision
- Ignoring ideas
Proself SM & High EM:
- Arguing and
counterarguing
- Independence
Prosocial & Low EM:
- Pressure on deviants
- Lazy compromising
Prosocial SM & High EM:
- Information pooling
- Attention to others’
ideas
Process Gain of Group
Brainstorming
Cognitive stimulation: Group members can
build off of each others
ideas to come up with
ideas that one wouldn’t
normally think of and
help start new trains of
thought
Process Losses of Group
Brainstorming
- Increase with group size
(Ringelmann effect) and explained
more by coordination losses than
motivation losses (brainstorming is
fun!)
Types of coordination losses in
brainstorming in groups:
* Evaluation apprehension,
especially in high-anxiety
groups
* Production blocking (from turntaking in groups, causes
cognitive interference)
IS GROUP IDEA GENERATION A GOOD
IDEA?
Groups generally do worse than individuals at brainstorming
(process losses > process gain)
BUT: people often think groups do better
* Why? Brainstorming feels subjectively easier in groups!
Group creativity: on a feasibility x originality graph
low feasibility and low originality: bad ideas
high feasibility and low originality: conventional ideas
low feasibility and high originality: crazy ideas
high feasibility and high originality: good ideas
Team creativity: difference between the additive model and the disjunctive model
additive model: Creativity is the result of the team average, meaning Average
individual creativity predicts team
creativity
disjunctive model: Creativity is promoted by the most creative members alone, meaning Highest
individual creativity predicts team
creativity
moderators for relationship between individual creativity and group creativity
- task interdependence: Average individual creativity has a stronger relationship with
team creativity when task interdependence is high, whereas
highest individual creativity has a stronger relationship with
team creativity when task interdependence is low. - Task creativity requirements: Average individual creativity is more positively associated with
team creativity when creativity requirements are lower BUT NOT ON THE OTHER SIDE - Idea implementation: Average individual creativity is less positively associated with
team creativity when team tasks require the implementation BUT NOT OTHER WAY AROUND - Team size: not supported by research
- Team longevity: Average individual creativity has a more positive relationship with
team creativity in teams with higher longevity. SIMILARLY
Highest individual creativity has a more positive relationship with
team creativity in teams with higher longevity
2 types of group member resources (inputs!) to make decisions
- member preferences
- member information
TYPES OF SOCIAL DECISION
SCHEMES
1.Unanimity wins
2. Majority wins
3. Proportionality wins
4. Truth wins
SOCIAL DECISION SCHEME (SDS)
THEORY
Individual preference affects groups composition (how many
people in a group
prefer each alternative)
Group composition leads to group decision
Social Decision Scheme mediates relationship between group composition and group decision
