What is a group?
o A collection of two or more people who interact with each other and are interdependent
Why do we belong to groups?
Group Characteristics
Group influences - social facilitation
Social facilitation
• Tendency to do better on simple tasks, but worse on complex tasks, when in presence of others and individual performance can be evaluated
• Ex: how we cook for ourselves vs how we cook when we have guests
• STUDY: cockroaches; start at one end and food at other end; test it by itself, then test it with others around it (in view); cockroaches get faster when others are there; THEN more complex; same task but a bend in the path to the food when observed by other roaches they’re actually so much slower
• Zajonc (1965) – presence of others + evaluation
- Increases psychological arousal
- Makes us more alert
- Makes us concerned for what others think of us (evaluation apprehension)
- Distracts us
Group influences - social loafing
Social Loafing
• Tendency to perform poorly on simple tasks, but better on complex tasks, when in the presence of others and are not being evaluated
• More present in men than women
• Blend in with the rest of the group
• Ringelmann effect: as you increase the number of people in the group, the individual input is less (too many people = inefficient)
• Cultural difference:
- Social loafing more likely to happen in individualistic cultures
Behaviour in Groups - Deindividuation
Group Decisions
o Are two (or more) heads better than one?
o Members should be:
- Stimulated by each other’s comments
- Attentive to person with most expertise
o Unique information vs. process loss
- All have unique information: one’s own unique opinion, but often fail to share this (leads to process loss)
o Couples – transactive memory
- Each person is responsible for knowing about certain things (ex: wife deals with paying hydro bill, husband deals with phone bill)
o Groups are more likely to share unique information when:
- Information is diagnostic
- Discussions lasts a long time
- People have assigned roles; information they are responsible for
Groupthink
o Mode of thinking people engage in when they are deeply involved in cohesive in-group
o Strivings for unanimity override the motivation to realistically appraise alternative courses of action
o Maintaining group cohesiveness becomes more important than uncovering the facts
When is groupthink most likely to happen?
Symptoms of groupthink
How to avoid groupthink:
Group polarization
Great person theory
Fielder’s Contingency theory
Gender differences in leadership
Glass cliff effect
Groups and Conflict
o Social dilemma
- Own interests are pitted against those of the group
- Most beneficial action for an individual can have harmful effects for the group
- Ex: Stephen King website
• He started writing a book and posted 2 installments that were free to access; but he said if 75% of the visitors pay 1$ then I will continue to upload installments; but if less than 75% donates then I will stop writing
- Prisoner’s Dilemma
• Usually more favourable to cooperate
• More likely to cooperate if you have a healthy relationship with the other person
• Collectivist cultures tend to make more cooperative moves than individualistic
Resolving Conflict - Tit-for-tat strategy:
Resolving Conflict - Threats
• Often cause conflict to escalate
Resolving Conflict - Negotiation
• Communication between opposing sides in a conflict involving offers and counteroffers aimed at arriving a solution
• Integrative solution
- Each side concedes the most on issues that are least important to them, but most important to the opponent
- Mediators can be very helpful in outlining the issues
