Group Dynamics (College Board AP® Psychology): Revision Note

Social facilitation & social loafing

• Cultural values shape how individuals perceive and behave within groups:

  • Individualism:

    • prioritizes personal goals, autonomy, and individual achievement over group membership

    • emphasizes uniqueness and personal responsibility

      • E.g. the United States, Western Europe

  • Collectivism:

    • prioritizes group harmony, interdependence, and collective goals over individual goals

    • emphasizes group memberships and relationships

      • E.g. Japan, China, many Latin American and African cultures

  • Multiculturalism:

    • values of cultural diversity within a society

    • acknowledges that multiple cultural identities can coexist

    • shapes how individuals perceive and interact with members of other cultural groups

• These cultural orientations influence group behavior, e.g.

  • social loafing is less pronounced in collectivist cultures

  • conformity rates vary depending on cultural orientation

Social facilitation

• Social facilitation is the finding that the presence of others affects performance depending on task difficulty:

  • Performance improves on well-learned or simple tasks

  • Performance is impaired on novel or complex tasks

• The presence of an audience increases physiological arousal, which strengthens the dominant (most practiced or automatic) response

  • E.g. an experienced cyclist performs better in a race (simple, well-learned task) with spectators watching than when alone

  • E.g. a student who has not yet mastered a concept performs worse on a problem in front of the class than when practicing alone

• Social inhibition is the opposite effect:

  • On difficult or unpracticed tasks, the presence of others impairs performance

  • Arousal increases the likelihood of errors when the dominant response is incorrect

• Social facilitation occurs in both humans and animals

  • E.g. cockroaches run simple mazes faster but complex mazes slower when other cockroaches are present

Social loafing

• Social loafing refers to the tendency for individuals to exert less effort on a task when working in a group than when working alone

  • It occurs because individual contributions are less identifiable, leading to reduced accountability (diffusion of responsibility)

    • E.g. in group work, some members contribute less because their individual effort is not singled out

• Key conditions affecting social loafing:

  • Identifiability: loafing decreases when individual contributions can be measured and identified

  • Task importance: loafing decreases when the task is personally meaningful or challenging

  • Group cohesion: loafing decreases in highly cohesive groups where members feel accountable to each other

  • Culture: social loafing is less pronounced in collectivist cultures, where group success is more personally meaningful

• Social loafing vs social facilitation:

  • Social facilitation occurs when individual performance is being evaluated

    • Presence increases effort and arousal

  • Social loafing occurs when individual performance is not being evaluated

    • Group context reduces effort

The false consensus effect

• The false consensus effect refers to the tendency to overestimate the extent to which other people share our own beliefs, attitudes, and behaviors

  • We assume our own views are more common than they actually are

    • E.g. a person who supports a particular political policy assumes most other people also support it

Group polarization & groupthink

Group polarization

• Group polarization is the tendency for group discussion to strengthen members’ initial attitudes, leading to a more extreme group position

  • If most members initially lean in one direction, discussion strengthens that tendency

    • E.g. a jury initially leaning toward a guilty verdict may become more convinced of guilt after deliberation

• Explanations for group polarization:

  • Persuasive arguments: group discussion exposes members to more arguments supporting the majority position, strengthening that position

  • Social comparison: members compare their views to others and shift toward a more extreme version of the group's position to appear consistent with group norms

Groupthink

• Groupthink is the tendency for highly cohesive groups to prioritize consensus and agreement over critical evaluation, leading to poor decision-making

  • Groupthink was proposed by Janis (1972), who studied flawed political and military decisions

• Conditions promoting groupthink:

  • High group cohesion and loyalty

  • Isolation from external viewpoints

  • A directive leader who signals a preferred outcome

  • High stress and pressure to decide

• Symptoms of groupthink:

  • Illusion of invulnerability: the group believes it cannot make serious mistakes

  • Collective rationalization: members dismiss or explain away warning signs

  • Illusion of unanimity: dissenting views are suppressed; silence is interpreted as agreement

  • Mindguarding: some members protect the group from contradictory information

  • Pressure on dissenters: members who raise objections face social pressure to conform

• Consequences:

  • Limited consideration of alternatives

  • Failure to assess risks

  • Lack of contingency planning

• E.g. Janis applied groupthink analysis to historical policy failures, arguing that flawed group decision-making contributed to events such as the Bay of Pigs invasion

Deindividuation

• Deindividuation occurs when group membership reduces self-awareness and personal responsibility, increasing the likelihood of atypical or antisocial behaviour

  • E.g. mob behavior, rioting, online harassment in anonymous forums

• Factors that promote deindividuation:

  • Anonymity (e.g., wearing a uniform, mask, or being part of a large crowd)

  • High arousal within the group

  • Diffusion of responsibility, where no single individual feels personally responsible for the group's actions

• Zimbardo's Stanford Prison Experiment (1971) illustrated deindividuation:

  • College students were randomly assigned to play the roles of prison guards or prisoners in a simulated prison

  • Guards quickly adopted abusive behaviors; prisoners became passive and distressed

  • The experiment had to be terminated after six days due to the psychological harm being caused

  • The study demonstrated that assigned roles and situational factors can lead to deindividuation and extreme behavior, even among people with no prior history of aggression

Superordinate goals and social traps

• Superordinate goals are shared goals that require cooperation between groups and cannot be achieved alone

  • They are one of the most effective means of reducing intergroup conflict and negative stereotyping

    • E.g. in Sherif’s Robbers Cave study, shared challenges (e.g. fixing water supply) reduced hostility between groups

• Social traps occur when individuals pursue short-term self-interest in ways that harm the group

  • Immediate individual gain leads to delayed, collective cost

    • E.g. overfishing benefits individuals short-term but depletes resources for everyone

Industrial-organizational (I/O) psychology

• I/O psychology studies behavior in the workplace and applies psychological principles to improve performance and wellbeing

• Key areas of I/O psychology:

  • Best practices in management: how leadership styles affect employee performance and satisfaction

  • Workplace relationships: how people work together effectively, including communication, conflict resolution, and team dynamics

  • Burnout: chronic work stress involving emotional exhaustion, depersonalization, and reduced accomplishment

    • Burnout is associated with high job demands, low autonomy, poor social support, and lack of recognition
