A set of individuals who directly interact over time and have a shared fate, goals or identity
Some say a group has to be made of 3 people
Collectives
People engaging in a common activity with little direct interaction with each other
Groups
They vary on whether they're integrated and coherent (fit really well together)
People get more satisfaction from being in that group
People identify more strongly with that group
Why join a group
Might need others to accomplish things (e.g., running a household, engaging in sports, creating art, etc.)
Basic human needs (safety in numbers, reproduction, etc.)
Social identity, we know who we are based on what groups were a part of
3 key features of groups
Roles
Norms
Cohesiveness
Roles
Set of expectations around behaviours, people may have roles and that could be what others expect them to do
Can be formal or informal
2 fundamental types of roles
Instrumental roles: help people achieve tasks, e.g., captain of a sports team
Expressive: providing emotional support to group members and maintaining morale
Groups function better when members are assigned the roles that best match their personalities and talents
Role uncertainty
Related to different issues, typically been studied within a workplace context (can lead to burnout, workplace bullying, etc.)
Norms
Rules of conduct for members (how you're supposed to behave or even think)
Can be formal or informal
Norms can often cause conformity amongst groups of people and groups may punish those who deviate from the norm
Groups vary in tolerance to norm violations
Cohesiveness
How much various different forces push group members to be closer together such as through feelings of intimacy, unity, and commitment to group goals
Feel commitment to group tasks
Feel positive toward other group members
Feel group pride
Interact often with each other
Group cohesion increases group performance and vice versa
Tight culture
Strong norms, little tolerance for norm deviating behaviour
Loose culture
Weaker norms, greater tolerance for deviant behaviour
Social facilitation
When the presence of others enhances performance on easy tasks but impairs performance on difficult tasks
Triplett's cyclist research, noticed cyclists who were racing were faster in the presence of other cyclists
The Zajonc 3-step solution
1. Presence of others increases physical arousal, energizes behaviour
2. Arousal enhances our tendency to perform the dominant response
3. Quality of performance varies based on the type of task
Zajonc cockroach studies: Easy maze - cockroaches were faster with audience, Difficult maze - cockroaches were slower with audience
Meta-analysis of 241 studies supported social facilitation
Many modern examples, e.g., driving tests, e-gambling, why firefighters, police officers, military personnel and other practice scenarios ad nauseum
Mere presence of others
Sufficient to produce social facilitation
Evaluation apprehension theory
Presence of other will produce social facilitation effects only when those others are seen as potential evaluators
Distraction-conflict theory
The presence of others will produce social facilitation effects only when those others distract from the task and create attentional conflict
Social loafing
A group-produced reduction in individual output on easy task in which contributions are pooled
Occurs during group tasks when an individual's effort cannot be determined
Ringelmann's pulling rope task, when part of a group people made less of an effort than when working individually
Strategies to reduce social loafing in group projects
Limit the scope of the project
Keep the group small
Use peer evaluations
Social loafing is less prevalent in women than in men and less prevalent in people from collectivist than individualist cultures
Group norms of low productivity in a collectivist culture can result in more social loafing
Deindividuation
When people lose their sense of individuality and experience reductions on the normal constraints of behaviour, are more likely to engage in deviant behaviour
Occurs in presence of others
Contributors to deindividuation
Arousal
Anonymity or accountability cues, more difficult to be held accountable
Attentional cues, things that pull attention away from the self (e.g., alcohol)
Group Polarization
The exaggeration of initial tendencies in the thinking of a group through group discussion
Causes of group polarization
Persuasive arguments theory: the more persuasive the arguments we are exposed to, the more extreme our thinking becomes on that topic
Comparison and categorization
E.g., group approves of carbon tax, onemember suggests doubling carbon tax
Ted talk on group polarization
Groupthink
A group decision-making style characterized by an excessive tendency among group members to seek agreement
3 pieces that contribute to groupthink
Highly cohesive groups
Group structure
Stressful situations
Steps to prevent groupthink
Avoid isolation
Consult widely with outsiders
Reduce group pressures to conform
Leaders should explicitly encourage criticism
Leaders should not take a strong stand early in discussion
Establish a strong norm of critical review
Subgroups should separately discuss the same issue
Assign a member to question all decisions and ideas
"Second chance" meeting to reconsider group decision
Criticisms of groupthink: Very difficult to experimentally test, Researchers disagree with janis's antecedents, Steps to prevent groupthink are more likely to improve decision making nonetheless
Social dilemma
A situation in which a self interested choice by everyone will create the worst outcome for everyone, e.g., using non-renewable resources
Pursuit of self interested choice can sometimes be self destructive
Prisoner's dilemma
One party must make either cooperative or competitive moves in relation to another party
