Chapter 13 Social Psychology

Situational Influence on Behaviour

Social psychology examines how situational factors shape individual and group behavior. These influences include mimicry, social norms, and roles, which guide how people act in various contexts.

Mimicry: Unconsciously copying others' actions, emotional displays, and facial expressions. This helps coordinate social interactions and fosters social bonds.
Social Norms: Unwritten rules about acceptable behavior in specific contexts. Violating norms can lead to negative consequences such as ostracism.
Roles: Expected behaviors associated with particular positions (e.g., student, professor, guard). Roles can strongly influence actions, as seen in the Stanford Prison Experiment.
Example: The #MeToo movement illustrates how social influence can empower individuals to share experiences and drive social change.

Additional info: Kurt Lewin's equation (Behavior is a function of the Person and Environment) highlights the interplay between individual traits and situational factors.

Synchrony and Mimicry

Humans often synchronize their behaviors, speech, and physiological activity during social interactions. Mimicry is mostly unconscious and signals attention and similarity.

Emotional Contagion: Displaying the same emotional expressions as those around you, which can influence mood.
Functional Mimicry: Acts as "social glue," reassuring and validating others.
Manipulation Risks: Conscious mimicry for manipulation can backfire if detected.

Norms and Roles

Social norms and roles guide behavior in groups and society. Adhering to norms is motivated by the desire for social approval.

Ostracism: Being excluded from a group can cause negative emotions and aggression.
Role Adaptation: People quickly adapt to assigned roles, sometimes leading to unexpected behaviors (e.g., abuse by guards in the Stanford Prison Experiment).
Perceived Norms: Misperceptions of norms (e.g., alcohol consumption) can influence behavior; correcting these can reduce negative outcomes.

Group Dynamics

Group behavior is shaped by mimicry, roles, and social norms. Individuals often behave differently in groups than when alone.

Social Loafing: Reduced effort in group tasks due to low efficacy, perceived irrelevance, lack of identification, or perceived loafing by others.
Mitigation Strategies: Structure tasks, provide feedback, clarify goals, and encourage social bonds.
Social Facilitation: Presence of others can enhance performance in simple tasks or for skilled individuals, but hinder performance in complex tasks or for novices.
Example: Cyclists ride faster against competitors; cockroaches run faster in the presence of others but perform worse in complex mazes.

Conformity

Conformity is changing behavior to fit in with a group, driven by social pressure or belief that the group has better information.

Normative Influence: Conforming to be accepted by a group, leading to public compliance.
Informational Influence: Conforming because the group is perceived as more knowledgeable, leading to private acceptance.
Factors Affecting Conformity: Group size, familiarity, task clarity, presence of nonconformists, and anonymity.
Example: Solomon Asch's studies showed participants conformed to incorrect answers in perceptual tasks.

Groupthink

Groupthink is a decision-making problem where group members avoid arguments and strive for agreement, often resulting in poor decisions.

Problems: Ignoring risks, settling quickly on ideas, overconfidence.
Historical Examples: Challenger shuttle disaster, Iraq war decisions.
Factors: Strong leaders, group similarity.

Obedience, the Bystander Effect, and Altruism

Situational factors can lead individuals to obey authority, fail to help in emergencies, or act altruistically.

Obedience: Milgram's experiments showed ordinary people could commit harmful acts under authority. About 65% of participants administered maximum shocks.
Bystander Effect: Individuals are less likely to help in emergencies when others are present due to diffusion of responsibility.
Altruism: Helping others selflessly, often driven by empathy and strong social bonds.
Example: The Kitty Genovese case spurred research on bystander behavior.

Module 13.1 Summary

Mimicry and conformity foster social bonds and prosocial behavior.
Social roles and authority figures amplify social pressures.
Bystander effect reduces likelihood of helping; clear communication and assigning responsibility can increase help.
Behavior is shaped by both personal traits and situational forces.

Social Cognition

Person Perception

Social cognition explores how people process information about the social world, including forming impressions, stereotypes, and biases.

Schemas: Organized clusters of knowledge and expectations about individuals and groups.
Implicit Processes: Unconscious, automatic judgments based on past experiences and cultural knowledge.
Thin Slices: Rapid judgments based on brief samples of behavior, often surprisingly accurate.
Example: Judging trustworthiness or competence from a photograph in less than a second.

Self-Fulfilling Prophecies

First impressions can influence social behaviors, leading to self-fulfilling prophecies where expectations shape interactions and reinforce initial impressions.

Modification: First impressions can change with new, diagnostic information.
Example: Jury verdicts and election outcomes influenced by perceived trustworthiness and competence.

The Self in the Social World

Self-concept and social identity influence how we perceive others and ourselves, often leading to Us vs. Them dynamics.

False Consensus Effect: Overestimating how much others share our beliefs and behaviors.
Naïve Realism: Assuming our perceptions are accurate and those who disagree are deluded.
Self-Serving Biases: Taking credit for successes, blaming failures on external factors.
Better-than-Average Effect: Believing we are above average in important qualities.
Attributions: Internal (personal traits) vs. external (situational factors) explanations for behavior.
Fundamental Attribution Error (FAE): Overemphasizing internal attributions for others' behavior.
Cultural Differences: Individualistic cultures emphasize internal attributions; collectivistic cultures focus on situational explanations.

Ingroups and Outgroups

We categorize ourselves and others into ingroups and outgroups, leading to biases and discrimination.

Minimal Group Paradigm: Even arbitrary group distinctions can lead to prejudice and discrimination.
Functional Aspects: Biases serve to reduce uncertainty, maintain self-esteem, and foster belonging.

Stereotypes, Prejudice, and Discrimination

Implicit and explicit processes contribute to stereotyping, prejudice, and discrimination, which can have destructive societal effects.

Stereotypes: Cognitive schemas about social groups.
Prejudice: Negative emotional attitudes toward outgroup members.
Discrimination: Behaviors disadvantaging certain groups.
Destructive "isms": Racism, sexism, classism.

Implicit Associations Test (IAT)

The IAT measures implicit biases by recording reaction times to schema-consistent and inconsistent pairings.

Block	Pairing	Average Response Time
First	White/Positive, Black/Negative	800 ms
Second	White/Negative, Black/Positive	1015 ms

Additional info: Longer response times for schema-inconsistent pairings indicate implicit bias.

Hostile vs. Benevolent Stereotypes

Stereotypes can be negative (hostile) or seemingly positive (benevolent), but both can restrict behavior and reinforce traditional roles.

Hostile Sexism: Explicitly negative views of one or both sexes.
Benevolent Sexism: Positive stereotypes that limit opportunities (e.g., women as nurturing).
Example: Men who are nurturing may be seen as less masculine.

Improving Intergroup Relations

Implicit biases can be reduced through practice, social contact, and exposure to non-stereotypic associations.

Contact Hypothesis: Intergroup contact, especially with equal status and cooperation, reduces prejudice.
Extended Contact Effect: Knowing a friend has an outgroup friend can decrease one's own prejudice.
Global Perspective: Viewing humanity as a single group can help overcome group prejudices.

Module 13.2 Summary

First impressions are formed quickly and can lead to self-fulfilling prophecies.
Attributions and biases shape perceptions of self and others.
Discriminatory acts can occur without explicit prejudice, influenced by cultural stereotypes.

Attitudes, Behaviour, and Effective Communication

Changing People’s Behaviour

Psychologists study how attitudes and behaviors can be changed to address social issues, such as climate change.

Technological Approach: Make desired behaviors easier and undesired behaviors harder (e.g., energy-efficient appliances).
Legal Approach: Policies and laws to encourage positive behaviors (e.g., regulations on waste).
Economic Approach: Financial incentives and penalties (e.g., tax breaks, fines).
Social Approach: Information campaigns to raise awareness and establish norms.
Combined Approaches: Using multiple strategies enhances effectiveness.

Persuasion: Changing Attitudes through Communication

The elaboration likelihood model (ELM) explains how persuasion works through two routes: central and peripheral.

Central Route: Focuses on facts and logic; requires motivation and time; leads to strong, lasting attitude change.
Peripheral Route: Relies on superficial cues (e.g., attractiveness); effective when motivation or time is low; can lead to quick, less stable attitude change.
Dual-Process Models: Distinguish between implicit (automatic) and explicit (deliberate) processes.

Making Messages Personal

Personal relevance increases motivation and effectiveness of persuasive messages.

Construal-Level Theory: Psychological distance affects impact; concrete, personal information is more persuasive.
Identifiable Victim Effect: Stories about specific individuals evoke stronger emotional responses than statistics.
Example: Study showed higher donations when presented with a single victim's story versus statistics.

Condition	Average Donation
Identifiable Victim	$2.38
Statistical Victims	$1.14
Combined	$1.43

Value Appeals

Messages are more effective when they align with the audience's values, but strategic framing is important to avoid unintended consequences.

One-Sided vs. Two-Sided Messages

Two-sided messages, which acknowledge opposing views, are generally more persuasive and enhance trustworthiness.

Attitude Inoculation: Presenting and refuting weak counter-arguments strengthens resistance to persuasion.
Straw Man Technique: Refuting weak or fabricated opposing arguments.

Clarity and Complexity in Communication

Overly complex messages can reduce motivation and comprehension, shifting audiences to the peripheral route.

Curse of Knowledge: Experts overestimate audience understanding, leading to ineffective communication.
Effective Tips: Simplify language, avoid jargon, and consider the audience's perspective.

Authority and Liking

Authority figures and likable communicators enhance persuasion, even outside their expertise.

Authority: Status and appearance increase influence.
Liking: Attractiveness and similarity boost persuasiveness.
Example: Attractive fundraisers and political candidates receive more support.

Social Validation, Reciprocity, and Consistency

Social influence tactics leverage norms, reciprocity, and consistency to change attitudes and behaviors.

Social Validation: Using others' behavior as a guide (e.g., bestseller lists).
Reciprocity: Repaying favors; used in marketing and persuasion (e.g., free samples).
Door-in-the-Face Technique: Large request followed by a smaller one increases compliance.
Foot-in-the-Door Technique: Small request followed by a larger one leverages need for consistency.
Commitments: Written and public commitments are especially effective.

The Attitude–Behaviour Feedback Loop

Attitudes and behaviors influence each other in a self-reinforcing cycle, with small changes leading to larger impacts over time.

Cognitive Dissonance

Cognitive dissonance theory explains how holding conflicting beliefs creates discomfort, motivating individuals to change attitudes or behaviors to reduce tension.

Festinger and Carlsmith Experiment: Participants paid $1 to lie experienced more dissonance and changed their attitudes, compared to those paid $20.
Doomsday Cult Example: Members changed beliefs to reduce dissonance when predictions failed.
Cultural Differences: Collectivistic cultures experience dissonance in interpersonal contexts rather than self-consistency.

Equation: Cognitive dissonance is reduced by changing attitudes, beliefs, or behaviors to restore consistency.

Module 13.3 Summary

Cognitive dissonance motivates attitude change to align with behavior.
Behaviors and attitudes reinforce each other.
Persuasive communication faces challenges due to psychological distance and complexity.
Peripheral route is often used when central route is ineffective.
