Social Psychology
Social Psychology looks at both intrapersonal (attitudes, persuasion, social cognition, cognitive dissonance) and interpersonal (relations with others, group dynamics, social influence, interpersonal attraction) phenomena
Discovering Psychology - The Power of the Situation
Attribution Process and Theory

How we attach meaning to other’s behavior, or our own, is called attribution
Attribution theory (Fritz Heider) People naturally see cause and effect relationships and seek to explain behavior
Dispositional versus situational attribution
Fundamental attribution error (others)
Self-serving bias (also defensive attribution) self only
Actor-observer effect
Why were you late for class? Why was Jimmy late for class?
Why did you fail the Psych test? Jimmy?
Just-world hypothesis
Cognitive Dissonance

Cognitive dissonance The tension caused by holding two contradictory ideas simultaneously. Includes attitudes and beliefs, and actions
Theory of cognitive dissonance proposes that people seek to reduce dissonance by changing their attitudes, beliefs, or behaviors, or by justifying or rationalizing their attitudes, beliefs, and behaviors in order to seek cognitive consistency (Festinger)
Cognitive Dissonance: Attitudes and Actions
According to Leon Festinger we seek cognitive consistency by bringing our attitudes closer to our actions called theory of cognitive dissonance or balance theory
Tedious task experiment $$ (Festinger)
Festinger CD
A(ttitude)-B(ehavior) Problem – To what extent do behaviors affect attitudes? Can one predict the other?
Cognitive Dissonance and Behavior
Role playing Subjects in a role often begin to “become” the role. Behavior affects attitudes and reduces dissonance (e.g. role playing – “I’m a teacher, dad, scholar…”)
Zimbardo prison pathology experiments
Foot-in-the-door theory The tendency for people who agree to a small request to comply later with a larger one (cheating, lying, drug use, torture…it’s a slippery slope!). Reduces initial dissonance. Also used in persuasion/sales
Effort justification the tendency to find something more attractive if you have to work hard to achieve it, Examples?
Role Playing and Zimbardo

Role playing and deindividuation and situational influences
Zimbardo prison experiments
- ZimbardoPE
- Zimbardo DN
- The Stanford Prison Experiment
Deindividuation

Deindividuation into a group results in a loss of individual identity and a gaining of the social identity of the group. Examples?
-Anonymity
-Diffused responsibility
-Group size

Social Influence and Conformity & Obedience

Conformity influences the maintenance of social norms and allows society to function smoothly
Other behaviors may be an expression of compliance (obedience) toward authority
Social Conformity (Asch)

Asch’s conformity experiments
Asch study
What are the factors which affect degree of conformity?
Normative social influence v. Informational social influence
Reasons for Conformity
Normative Social Influence Results from a person’s desire to gain approval or avoid rejection. Public compliance, but doubt. Number, strength and immediacy. Asch Conformity Studies
Two polar bears are sitting in a bathtub. The first one says, "Pass the soap". The second one says, "No soap, radio!" (anti-humor – false and negative understanding)
ConformityCC
Reasons for Conformity - Informational

Informational Social Influence Look to group to make accurate judgments
Also called social proof. It occurs most often when
The situation is ambiguous.
There is a crisis. We have no time to think and experiment. A decision is required now!
Other Types of Conformity & Phenomena

-Chameleon effect
-Mood linkage (emotional or social contagion)
-Suggestibility
Obedience to Authority

The Milgram Experiments
-Milgram Video
-The Power of the Situation
Social Obedience (Milgram)
Results and Explanations for Milgram’s Obedience to Authority experiments
-Socialization (normative influence)
-Foot in the door phenomenon
-Perception of legitimate authority
-Diffusion of responsibility
-Inaccessibility of values
-Lack of social comparison
-Physical and psychological buffers (proximity,
depersonalization)
Ethicality of the experiment?
Social Identity Theory and Prejudice
Social Identity Theory Identity is formed through the groups to which we belong. We are motivated to improve the image and status of our own group in comparison with others (Tajfel)
Categorizing people (including oneself) into ingroups or outgroups affects perceptions, attitudes, and behavior (key source of prejudice and discrimination) Tajfel and Social Identity Theory

Social Identity Theory and Prejudice

Group Dynamics and Prejudice
Sherif’s Robbers Cave experiment (1961)
Realistic Conflict Theory Limited resources lead to conflict between groups and result in prejudice, discrimination and stereotypes within a society
-In Group homogeneity and Out Group bias (basis of stereotype and prejudice). Stages: 1) In Group formation 2) friction and competition and 3) integration
-Superordinate goals
-Contact hypothesis
-GRIT
-PsyBlog: War, Peace and the Role of Power in Sherif's Robbers Cave Experiment
Prejudice and Discrimination
Prejudice is an unjustifiable (usually negative) attitude toward a group and its members. Prejudice underlies the behavior of discrimination
Components of Prejudice
-Beliefs (stereotypes)
-Emotions (hostility, envy, fear)
-Predisposition to act (to discriminate)
Social, Emotional and Cognitive Roots of Prejudice

Social inequality, social division and emotional outgroup and ingroup bias
An outlet for blame, anger and resentment Scapegoat Theory
Just world phenomenon
Unconscious Prejudice
Prejudice works at the conscious and [even more at] the unconscious level. Prejudice is more a knee-jerk response than a conscious decision which then results in behavior (discrimination)
-Implicit Association Test
-Discrimination – A Class Divided
Group Dynamics

How does the presence of others influence individual behavior?
- Social loafing
- Social facilitation
- Group polarization (incestuous amplification and risky shift) not groupthink
- Deindividuation
- Groupthink (rationalized conformity) and mindguard
Groupthink and Mindguard

Groupthink When norms for conforming in a homogeneous group become so strong, and members are so highly concerned about maintaining unanimity, that they fail to critically evaluate their options and consequently make a poor decision
Examples...Iraq invasion, Bay of Pigs, Challenger disaster…
Role of mindguard
Bystander Effect

Bystander intervention v. bystander apathy/effect (Kitty Genovese)
First demonstrated by Darley and Latane (1968) Participants are assigned to alone or group condition (comprised of confederates). A crisis situation is staged; a person getting injured, a person having a seizure...How do participants react?
Consistent Results: The presence of others inhibits helping…
- Diffusion of responsibility/social loafing
- Pluralistic ignorance
- Bystander intervention
The Psychology of Helping
Altruistic and Prosocial behavior
Social norms theory States that much of people’s behavior is influenced by their perception of how other members of their social group behave
Social exchange theory An economic-social theory that assumes human relationships are based on choice and cost-benefit analyses = Social benefits
If one partner's costs begin to outweigh his or her benefits, that person may leave the relationship, especially if there are good alternatives available
Theory of Social Comparison

Theory of Social Comparison (Festinger) Humans gain information about themselves, and source self-esteem, by comparison to others
- Upward social comparison Individuals compare themselves to others who are “socially better” to view self more positively
- Downward social comparison A defensive tendency to evaluate oneself in comparison with others whose troubles are more serious than one's own
Persuasion and the Elaboration Likelihood Model

Persuasion can be divided into two separate processes based on the "likelihood of cognitive elaborations," that is, whether people think critically about the content of a message, or respond to superficial aspects of the message and other immediate cues
Central and peripheral routes to persuasion
The Psychology of Aggression
Bio-psychosocial model
Biological Sources/Causes (brain, hormones, genetics, evolutionary - instinct theory)
Psychological sources
- Social scripts
- Observational learning and reinforcements
- Frustration-aggression hypothesis
Psychology of Attraction
Factors affecting attraction
- Proximity/propinquity – mere exposure effect
- Primacy (first impressions)
- Physical attractiveness (facial matching)
- Similarity
- Complementarity (not dissimilarity)
- Reward theory of attraction/social exchange
- Intimacy
Theories of interpersonal attraction – reinforcement, equity and cognitive consistency (balance)
