Chapter 8 Flashcards
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?
- Innate need
• Proof: isolation/confinement in prisons
• Fundamental need for social interaction; physical and mental well-being - Self-identity
• How do we know if we’re nice, funny, clever etc…
• Interactions with people help formulate identity - Textbook: belonging to groups important for social change; advancing society (ex: bringing attention to things that we find important)
Group Characteristics
- Social norms (expectations on what is normal behaviour; can be explicit or unspoken)
- Similarity (background, sexual orientation…)
- Social roles (norms are what’s expected from everyone; roles are what’s expected from an individual, ex: clown, leader)
- Cohesion (how close knit the group is); measured by:
• Willingness to stay in the group
• How often you take part in group activities
• Try to recruit like-minded members (do this more when we’re high in cohesion)
• Task cohesion: how well we work together
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
- Loosening of normal constraints on behaviour when people are in a crowd (ex: rioting, looting, partying, flash mobs)
- How does it work?
• Accountability
• Self-awareness
• Group norms
• Uniforms/anonymity/savagery
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?
- Highly cohesive
- Isolated from contrary opinions
- Ruled by a directive leader
Symptoms of groupthink
- Illusions of invulnerability creating excessive optimism and encouraging risk taking
- Rationalizing warnings that might challenge the group’s assumptions
- Unquestioned belief in the morality of the group = ignore the consequences of their actions
- Stereotyping those opposed to the group as weak, incompetent, or stupid
- Direct pressure to conform placed on any member who questions the group, couched in terms of “disloyalty”
- Self censorship of ideas that deviate from the apparent group consensus
- Illusions of unanimity among group members, silence is viewed as agreement
- Mindguards – self-appointed members who shield the group from dissenting information
How to avoid groupthink:
- Leader remaining impartial
- Invite outside opinion
- Divide group into independent sub-groups
- Each member acting as critical evaluator
- Using secret voting
- Having a devil’s advocate
Group polarization
- Tendency for groups to make decisions that are more extreme than the initial inclinatinon of their members
- Start as risky; riskier in group
- OR Conservative; more conservative in group
- Depending on what others are saying we will be swayed to one or the other
Great person theory
- Key personality traits regardless of situation
• Intelligence
• Charisma
• Motivation
• Self-confidence
• Dominance
But; STUDY: most successful presidents
• Tall, small family, published many books
• Good leadership: integrative complexity - Ability to be able to integrate various perspectives
Fielder’s Contingency theory
- Right person at the right time in the right situation
• Person: task vs. relationship-oriented (recognize you need to connect with ppl. to motivate them)
• Situation: high vs. low control (low: leader doesn’t have respect; people don’t listen…) - Relationships with subordinates, leader’s position, nature of task
- Task-oriented leaders better in very high or very low control
- Relationship-oriented leaders better in moderate control
Gender differences in leadership
- Women
• Expected to be more “communal” (helpful, kind, warm, affectionate)
• More effective when interpersonal skills are important - Men
• Expected to be more “agentic” (assertive, controlling, dominant, self-confident)
• More effective when the need is to direct and control
