Group Cognition Flashcards
Group function
Hill (1982)
Evidence of process loss and process gain
Process gain- through process of group discussion- get right answer
Process loss- acting crowds hinders ability to get right answer
Groups performed at accuracy of second best member
Why comparing groups is hard
Task type
Intellective (involves reasoning) vs judgement task
Well defined (clear success metric) vs ill defined
Required insight
Required background knowledge
Provoke strong intuitions or emotions
Why comparing groups is hard
Standards of comparison
Consider where people are individually on performance
Synergy- collaboration group performance is better than best individual
Why comparing groups is hard
Coordination methods
Averaging- just collect ppts individual answers and no discussion
Iterative- everyone gives answers, sees answers of other people and get to change
Pick best individual answer-> dictator method- group decides who they think will be the best person to answer
Why comparing groups is hard
Individual differences
Do they have different sources of info- access to cues
Do they differ in ability
In other capacities
Gigone and Hastie
1997
Lens model
Never really see the world just given cues that tell us how to see it/ construct representation of it
Various cues we can pay attention to, come to different judgements by cues- combined in group judgement
Revision- what someone else says changes own judgement
Errors
Independent estimates- not influenced by other judgements
Uncorrelated errors- more judgements can get better estimate of true value and can get rid of noise
Correlated errors due to: limited info, individual bias, group conformity
No systematic biases
No coordination between group members
Group think
Polarisation in group decision making
Group become obsessed in single view answer
Overconfident that it’s right
Blindness to errors
Due to conformity
Social account of reason
Interactionist account- reason evolved to produce and evaluate arguments
Primary reason to create arguments is to persuade other people
Wason task in small groups
Normally 80% fail
In groups 80% get right answer
Truth wins scenario- someone gets right answer and manages to persuade everyone in the group
How groups reason
Exchange of arguments
Groups typically co constructed a structure of arguments qualitatively more sophisticated than that generated by most people - justify beliefs
Show synergy
Collective intelligence
G- inspired by idea of general intelligence
C- collective intelligence
Does the general intelligence (individual) after the collective intelligence (group)
Predictors of group intelligence
Average social sensitivity
Amount of communication
Distribution of communication
Coordination problem of group work often overweight the intellectual intelligence
Higher social perceptiveness (RME)= better group discussion
