Chapter 2: Groups

1. Chapter 2: Groups Social Psychology by Tom Gilovich, Dacher Keltner, and Richard Nisbett

2. What is a Group? two or more people who: • interact with each other directly or indirectly • share common goals/share norms • have a stable relationship • are interdependent • perceive they are part of a group not a collection of people in a lobby, street corner, or elevator

3. Group Formation and Function • People join groups to: • satisfy important needs (e.g., belonging, safety) • reach goals they cannot achieve alone • boost their self-identity • Groups function through: • roles- expected behavior for different positions • status- social standing within group • norms- rules for behaving within group • cohesiveness- forces that cause members to stay in group (attraction, desire for status)

4. Decision-Making in Groups Social Decision Schemes- rules comparing initial group views to final group decisions • majority-wins rule- group opts for whatever decision majority agreed with initially • truth-wins rule- group eventually accepts correct decision • first-shift rule- groups adopt decision consistent with direction of first shift in opinion these simple rules predict final outcome 80% of time

5. Consequences of Group Decision Making • Conventional wisdom suggests groups would make better decisions than individual • Greater informational resources • More likely to identify and correct errors • Not clear if groups make better decisions than individuals • Group polarization • Groupthink • Mixed research support

6. Risky Neutral Cautious Group Polarization Group Polarization- tendency to shift toward more extreme positions after group discussion

7. Groupthink

8. Mixed Research Support • Most group decision research takes place in lab • Groups are not “real” groups • Group development theories suggest groups need time to develop effective interaction patterns • (e.g., Tuckman and Jensen) • Forming • Storming • Norming • Performing • Lab groups don’t have time to develop so effectiveness could hinge on personality of most competent member

9. Social Facilitation Definition: The effect, positive or negative, of the presence of others on performance. 1. Initial Research a. Triplett (1898)

13. Sources of Arousal • Evaluation Apprehension • A concern about looking bad in front of others • Cottrell, et, al. 1968

14. Sources of Arousal • Mere presence • Presence of others is arousing • Cockroaches probably not worried about looking bad • Markus (1978)

15. Tendency to pay attention to audience or coactors Tendency to pay attention to task Social Facilitation Distraction-Conflict Theory Conflict Organism performing some task Presence of audience or coactors Increased arousal Social facilitation effects

16. Tendency to slack off when individual effort cannot be monitored Social Loafing Latane’, Williams, and Harkins (1979) Potential productivity Pseudogroup productivity Actual group productivity

17. Conflict in Groups • Other causes of conflict besides incompatibility • Faulty attributions—erroneous blame • Poor communication—misinterpreted criticism, grudges • Tendency to see own views as objective, while others have biased views • Status quo bias—powerful groups often inaccurate • Type A personality—highly competitive and hostile Conflict—perceived incompatible interests

18. Integrative Dimension Distributive Dimension High Concern for Achieving Goals Low Low High Concern for Relationships Strategies for Dealing With Conflict Competing Collaborating Compromising Accommodating Avoiding

19. Perceived Fairness in Groups • The presence of others affects our judgments of fairness • Judgments typically made by social comparison • Fairness can be judged in terms of: • outcomes (distributive justice) • Equity distribution • Equality distribution • Need distribution • procedures (procedural justice)

20. Equity Theory Perceived inequity creates a state of “unpleasant” tension that we are motivated to reduce How do we perceive inequity (unfairness)? According to Adams, inequity is perceived when our perception of the ratio of our Inputs to Outputs is different from that of a comparison other .

According to Adams, inequity is perceived when our perception of the ratio of our Inputs to Outputs is different from that of a comparison other . An example: Larry Moe Curly our perception Inputs – amount of work, KSAs, experience Outputs – pay, promotions, perqs
