CUET UG Psychology Social Psychology Social Influence Conformity Obedience Group Dynamics

Must-Know

• Conformity is a change in behaviour or belief to match group norms due to real or imagined group pressure; example: Asch’s line judgment experiment where 75% of participants conformed at least once.
• Solomon Asch conducted the classic conformity experiment in 1951 using unambiguous line-length tasks with 12 critical trials.
• In Asch’s experiment, group size of 3–5 increased conformity; larger groups had minimal additional effect.
• Asch found that presence of one dissenting confederate reduced conformity by up to 75%.
• Obedience is compliance with direct orders from an authority figure; example: Milgram’s shock experiment (1963) where 65% of participants administered the maximum 450-volt shock.
• Stanley Milgram’s obedience study was conducted at Yale University in 1961 to examine obedience to authority during the Holocaust era context.
• In Milgram’s baseline study, 26 out of 40 participants (65%) obeyed fully despite victim’s protests.
• Proximity to authority decreased obedience: when the experimenter gave orders by phone, obedience dropped to 20.5%.
• Physical proximity to the "learner" increased emotional distress and decreased obedience; when teacher and learner were in the same room, obedience fell to 40%.
• Group dynamics refer to the interactions and psychological relationships that develop within a group over time.
• Social loafing is the tendency of individuals to exert less effort when working collectively than individually; example: clapping louder alone than in a group (Latané et al., 1979).
• The rope-pulling experiment by Latané, Williams, and Harkins (1979) demonstrated social loafing in collective tasks.
• Deindividuation is the loss of self-awareness and self-restraint in group situations that foster anonymity; example: mob violence or online trolling.
• Zimbardo’s Stanford Prison Experiment (1971) illustrated deindividuation and role adoption; it was terminated after 6 days due to extreme behaviours.
• Group polarization is the tendency for group discussion to strengthen the dominant viewpoint; e.g., riskier decisions in groups (risky shift).
• Groupthink occurs when the desire for harmony in a group overrides realistic decision-making; example: NASA’s decision to launch Challenger despite known risks.
• Symptoms of groupthink include illusion of invulnerability, collective rationalization, and pressure on dissenters.
• Normative social influence leads to public compliance without private acceptance, driven by desire to be accepted.
• Informational social influence occurs when individuals accept evidence about reality provided by others, especially in ambiguous situations.
• The autokinetic effect experiment by Sherif (1935) demonstrated informational social influence in forming group norms in ambiguous settings.

Difficulty Level

Intermediate — requires understanding of experimental setups and psychological mechanisms, but concepts are directly from NCERT Class XII Psychology textbook (Chapter 7: Social Influence and Group Processes).

Common CUET Traps

• Trap: Confusing conformity and obedience as interchangeable terms. Avoid: Conformity is peer/group pressure without authority; obedience is response to direct orders from authority.
• Trap: Attributing 100% obedience in Milgram’s study. Avoid: Only 65% (26/40) reached the highest shock level; the exact percentage is frequently tested.
• Trap: Believing social loafing increases with group size linearly. Avoid: Effort decreases initially but plateaus; also, it is reduced in cohesive or culturally collectivistic groups.

Practice MCQs

1. Question: In which experiment did participants administer what they believed were electric shocks to a learner?
   A. Asch’s line experiment
   B. Zimbardo’s prison study
   C. Milgram’s obedience study
   D. Sherif’s autokinetic effect study
   Answer: C
   Explanation: Milgram’s 1963 study examined obedience by instructing participants to administer shocks to a learner for incorrect answers.
   Why others fail: Asch’s experiment tested conformity, not obedience, making A a common confusion.

2. Question: What percentage of participants in Milgram’s baseline obedience study administered the maximum 450-volt shock?
   A. 40%
   B. 50%
   C. 65%
   D. 75%
   Answer: C
   Explanation: 65% (26 out of 40) participants obeyed fully, a key fact from NCERT.
   Why others fail: 75% is the conformity rate in Asch’s study, often misremembered as Milgram’s result.

3. Question: Which factor reduced conformity in Asch’s experiment significantly?
   A. Increasing group size to 10
   B. Making the task more difficult
   C. Presence of one dissenting confederate
   D. Anonymous response submission
   Answer: C
   Explanation: A single dissenter lowered conformity from 33% to about 8%, showing social support reduces pressure.
   Why others fail: Larger groups increase conformity only up to a point, but one dissenter has a disproportionate effect.

4. Question: Social loafing is best demonstrated by:
   A. Increased effort in group tasks due to motivation
   B. Reduced individual effort in group settings
   C. High conformity in decision-making groups
   D. Obedience to authoritarian leaders
   Answer: B
   Explanation: Social loafing refers to decreased individual effort when people work collectively.
   Why others fail: Students may confuse it with groupthink, but loafing is about effort, not decision bias.

5. Question: Which of the following is a symptom of groupthink?
   A. High level of critical thinking
   B. Illusion of unanimity
   C. Encouragement of dissent
   D. Use of external experts
   Answer: B
   Explanation: Illusion of unanimity is a hallmark symptom where members believe everyone agrees, suppressing disagreement.
   Why others fail: Option C seems correct but is actually a way to prevent groupthink, not a symptom.

Last‑Minute Revision

• ⚠️ Asch’s conformity study: 1951, line judgment task, 75% conformed at least once.
• ⚠️ Milgram’s obedience study: 65% gave 450V shocks; conducted in 1961 at Yale.
• ⚠️ Group size in Asch’s study: 3–5 confederates optimal for conformity.
• ⚠️ One dissenter in Asch’s study reduced conformity by 75%.
• ⚠️ Obedience drops to 20.5% when orders given by phone (Milgram variation).
• ⚠️ Social loafing: reduced effort in groups; demonstrated in rope-pulling experiment.
• ⚠️ Deindividuation: loss of self-awareness in crowds; Zimbardo’s prison study.
• ⚠️ Stanford Prison Experiment: 1971, stopped after 6 days, role adoption.
• ⚠️ Group polarization: group discussion strengthens initial attitudes.
• ⚠️ Groupthink: flawed decision-making due to harmony-seeking; Challenger disaster example.
• ⚠️ Normative influence: compliance to gain approval, public not private change.
• ⚠️ Informational influence: occurs in ambiguity, leads to internalization.
• ⚠️ Sherif’s autokinetic effect study: 1935, group norms formed in ambiguous situations.
• ⚠️ Conformity: peer pressure; obedience: authority command — distinguish clearly.
• ⚠️ Social loafing less in collectivistic cultures — NCERT example: Chinese students.
• ⚠️ Deindividuation increases in anonymous, arousing group settings.
• ⚠️ Zimbardo linked deindividuation to altered consciousness in groups.
• ⚠️ Milgram’s agentic state: individuals see themselves as agents of authority.
• ⚠️ Autokinetic effect: stationary light appears to move in dark — used by Sherif.
• ⚠️ Asch used 18 trials: 12 critical, 6 filler — verify from NCERT.
