Group Processes: Influence in Social Groups

Introduction to Social Influence in Groups

  • The Exam Scenario and Environmental Impact: Consider a final exam for a psychology class where the student is prepared but the room is tiny and packed.   - The Choice: Students are given the option to take the test in the crowded environment or in smaller, quieter rooms down the hall.   - The Scientific Question: Does the presence of a group impact behavior? The answer is yes; being in a group setting affects performance, learning, and overall behavior.   - Three Primary Phenomena:     - A. Social Facilitation     - B. Social Loafing     - C. Deindividuation

Defining and Characterizing Groups

  • Definition of a Group: A group consists of two or more people who interact and are interdependent. Their interdependence implies that their needs and goals cause them to influence one another.

  • Reasons Why People Join Groups:   - Belonging and Identity: Groups are a critical aspect of personal identity, helping individuals define who they are.   - Distinctiveness: Groups help individuals feel distinct from other social collectives.   - Establishment of Social Norms: Groups provide a framework for acceptable behavior.   - Informational Social Influence: Groups serve as an important source of information, helping members resolve ambiguity in the social world.

Social Roles and the Stanford Prison Study

  • Social Norms vs. Social Roles:   - Social Roles: Unlike general norms that apply to all members, social roles are shared expectations in a group regarding how particular people are supposed to behave.   - Potential Costs: If an individual becomes too enmeshed in a role, their personal identity and personality can be lost.

  • The Stanford Prison Experiment (Zimbardo et al., 1973):   - Methodology: Male volunteers were randomly assigned to play the role of either a prisoner or a guard in a mock prison for a planned duration of two weeks.   - Outcome: Students assumed their roles so quickly and intensely that the experiment was terminated after only 66 days.   - Guard Behavior: Became abusive, verbally harassed, and humiliated the prisoners.   - Prisoner Behavior: Became passive, helpless, and withdrawn.   - Phil Zimbardo’s Conclusion: "What's bad is the barrel." This suggests that a bad environment (the barrel) can corrupt good people (the apples), rather than it being a matter of individual character flaws.

Group Cohesiveness and Diversity

  • Group Cohesiveness: This refers to the qualities of a group that bind members together and promote mutual liking.   - Consequences of High Cohesiveness: Members are more likely to stay in the group, participate in activities, and recruit like-minded individuals.   - Impact on Performance:     - Task-Oriented Groups: If the function is to solve problems (e.g., military, sales team), high cohesiveness generally helps performance on complex tasks.     - Relationship-Oriented Groups: If the primary function is maintaining relationships, cohesiveness can interfere with optimal performance because harmony is prioritized over finding the best solution.

  • Group Diversity: Group members often share similar ages, sexes, beliefs, and opinions.   - Homogeneous Groups: Tend to be more cohesive.   - Diverse Groups: Research indicates that diverse groups tend to perform better.   - Business Context: Figure 9.19.1 highlights that racial and gender diversity correlate with better business performance.

Group Impact on Individual Performance

  • Social Facilitation: The tendency for people to do better on simple tasks and worse on complex tasks when they are in the presence of others and their individual performance can be evaluated.   - Conditions for Arousal:     - 1.1. Performing a task with coworkers doing the same thing.     - 2.2. Performing a task in front of an observing audience.   - Mechanics of Arousal: The presence of others increases physiological arousal.     - Arousal makes it easier to perform simple, well-learned tasks.     - Arousal makes it harder to learn something new or perform complex tasks.   - Theories of Arousal:     - 1.1. Alertness and Vigilance: Other people make us more aware of our surroundings.     - 2.2. Evaluation Apprehension: Concern about how others are judging us.     - 3.3. Distraction/Divided Attention: The presence of others distracts us from the task.

  • Social Loafing: The tendency for people to relax when they are in the presence of others and their individual performance cannot be evaluated.   - Ringelmann (19131913): Found that when individuals pulled a rope in a group, each person exerted less effort than when pulling alone.   - Performance Outcomes: Individuals do worse on simple tasks but better on complex tasks (because they are relaxed and not experiencing evaluation apprehension).   - Gender Differences: A review of over 150150 studies suggests social loafing is more common in men. Women tend to be higher in relational interdependence, making them less likely to loaf.

Deindividuation: The Influence of Anonymity

  • Definition: The loosening of normal constraints on behavior when people cannot be differentiated (anonymity), leading to an increase in impulsive and deviant acts.   - Historical Examples: Soccer mobs, rock concert tramplings, and lynchings committed by the KKK while wearing robes and hoods.

  • Research Findings (Robert Watson, 19731973): Studied 2424 cultures and found that warriors who used face and body paint to hide their identities were significantly more likely to kill, torture, or mutilate prisoners.

  • Mechanisms of Deindividuation:   - Accountability: People feel less likely to be held responsible for their actions.   - Obedience to Group Norms: Individuals follow the norms of the specific group they are in at that moment, which may be aggressive or antisocial.

  • Online Deindividuation:   - Cyberspace provides anonymity that can lead to a reduction in common civility.   - Internet Trolling: A modern example of deindividuation.   - Positive Side: Can also allow for free and open discussion of difficult or taboo topics.

Group Decision-Making and Problem Solving

  • Transactive Memory: The combined memory of two people that is more efficient than the memory of either individual alone.

  • Process Loss: Any aspect of group interaction that inhibits good problem solving.   - Causes: Groups may fail to identify the most competent member, the competent member may fear disagreement, or communication problems may arise.

  • Information Sharing: Groups tend to focus on shared information (what everyone already knows).   - Why?: Sharing common information makes a member appear more competent and credible.   - Solutions: Discussions should last long enough to exhaust shared info; assign specific areas of expertise to different members.

  • Groupthink: A style of thinking where maintaining group cohesiveness and solidarity is more important than considering facts realistically.   - Antecedents: High cohesiveness, isolation from contrary opinions, and a directive leader.   - Avoiding Groupthink: Leaders should remain impartial, seek outside opinions, create subgroups, and utilize anonymous opinions.

Group Polarization and Conflict

  • Group Polarization: The tendency for groups to make decisions that are more extreme than the initial inclinations of individual members.   - Direction: If initial tendencies are risky, the group becomes riskier; if cautious, the group becomes more cautious.   - Interpretations:     - 1.1. Persuasive Arguments: Members are exposed to new arguments they hadn't considered before.     - 2.2. Social Comparison: Members check the group's pulse and then take a position similar to others but a bit more extreme to be seen as a "good" group member.

  • Social Dilemmas and Conflict:   - Social Dilemma: A conflict where the most beneficial action for an individual, if chosen by most people, becomes harmful to everyone.   - The Prisoner’s Dilemma: A game where two people must choose between cooperation or competition.     - Example: Both choose X, win $3\$3 each. You choose Y (defect) while friend chooses X, you win $6\$6 and friend loses $6\$6.

  • Strategies to Increase Cooperation:   - Trust Building: People cooperate more with friends or those they expect to interact with later.   - Labeling and Norms: Changing a game name from "Wall Street Game" to "Community Game" increased cooperation from 33%33\% to 71%71\%.   - Representative Negotiation: Using a single representative from rival sides can bridge gaps better than whole-group interaction.   - Tit-for-Tat Strategy: Initially cooperating, then responding exactly as the opponent did in the previous trial. This communicates both a willingness to cooperate and a refusal to be exploited.
