Social Thinking and Social Influence
Social Thinking
12-1: WHAT DO SOCIAL PSYCHOLOGISTS STUDY?
HOW DO WE TEND TO EXPLAIN OTHERS’ BEHAVIOR
AND OUR OWN?
• Social psychologists
– Use scientific methods to study how people think
about, influence, and relate to one another
– Study the social influences that explain why the same
person will act differently in different situations
Social Thinking and Social Influence
Social Thinking
The Fundamental Attribution Error
• Attribution theory, Fritz Heider (1958): The theory that we
explain someone else’s behavior by crediting either the
situation (a situational attribution) or the person’s disposition
(a dispositional attribution).
– The fundamental attribution error is the tendency,
when analyzing others’ behavior, to overestimate the
influence of personal traits and underestimate the effects
of the situation.
• Fundamental attribution error demonstrated in a study
(Napolitan & Goethals,1979):
– Students attributed behavior of others to personal traits,
even when they were told that behavior was part of an
experimental situation.
Social Thinking and Social Influence
Social Thinking
The Fundamental Attribution Error
What Factors Affect Our Attributions?
• Cultural factors:
– Individuals from individualist cultures (Westerners) more
often attribute behavior to personal traits.
– Individuals from collectivist cultures (East Asian, for
example) more often attribute behavior to situational
factors.
• When we explain our own behavior, we are sensitive to how
behavior changes the situation.
• We are also sensitive to the power of the situation when we
explain the behavior of people we have seen in different
situations.
• Is most likely to occur when judging others’ behaviors, not
our own, and especially when a stranger acts badly.
Social Thinking and Social Influence
Social Thinking
The Fundamental Attribution Error
What Are the Consequences of Our Attributions?
• Explaining and attributing actions can have important
real-life social and economic effects.
– A person’s friendliness may be attributed to romantic
interest or politeness.
– Unemployment and poverty may be attributed to
personal dispositions.
• The point to remember: Our attributions—to a person’s
disposition or to the situation—have real consequences.
Social Thinking and Social Influence
Social Thinking
Attitudes and Actions
12-2: HOW DO ATTITUDES AND ACTIONS INTERACT?
• Attitudes are feelings influenced by beliefs, that
predispose reactions to objects, people, and events.
Attitudes Affect Actions
– Peripheral route persuasion occurs when people
are influenced by incidental cues; produce fast but
relatively thoughtless changes in attitudes.
– Central route persuasion occurs when people are
offered evidence and arguments to trigger thoughtful
responses.
• Attitudes are especially likely to affect behavior when
external influences are minimal, and when the attitude is
stable, specific to the behavior, and easily recalled.
Social Thinking and Social Influence
Social Thinking
Attitudes and Actions
Actions Affect Attitudes
• Not only will people stand up for what they believe, they also
will more strongly believe in what they have stood up for.
• Foot-in-the-door phenomenon
– People agreeing to a small request will find it easier to
agree later to a larger one
– Principle works for negative and positive behavior
• Many streams of evidence confirm that attitudes follow
behavior. Cooperative actions, such as those performed by
people on sports teams, feed mutual liking. Such attitudes, in
turn, promote positive behavior.
Social Thinking and Social Influence
Social Thinking
Attitudes and Actions
Role Playing Affects Attitudes
– A role is a set of expectations (norms) about a social
position, defining how those in the position ought to
behave.
– At first, your behaviors in a new role may feel phony,
as though you are acting, but eventually these new
ways of acting become a part of you.
– Philip Zimbardo’s 1972 Stanford Prison simulation
study: controversial, but showed the power of the
situation and of role playing.
– Other studies have shown that role playing can even
train torturers (Staub, 1989).
Social Thinking and Social Influence
Social Thinking
Attitudes and Actions
Cognitive Dissonance: Relief From Tension
• Cognitive dissonance theory: We act to reduce the
discomfort (dissonance) we feel when two of our thoughts
(cognitions) are inconsistent.
– When we become aware that our attitudes and our
actions clash, we can reduce the resulting dissonance by
changing our attitudes.
– Brain regions the become active when we experience
conflict and negative arousal also become active when
people experience cognitive dissonance.
– Through cognitive dissonance we often bring attitudes
into line with our actions (Festinger, 1957). This can be
used positively: Act as though you like someone and you
soon may.
Social Thinking and Social Influence
Social Influence
Cultural Influences
12-3: HOW DOES CULTURE AFFECT OUR BEHAVIOR?
Culture: The enduring behaviors, ideas, attitudes, values,
and traditions shared by a group of people
• Transmitted from one generation to the next
• Transmits customs and beliefs that enable us to
communicate with each other
• Transmits agreed-upon rules to avoid confrontation
Variation Across Cultures
• Norm: Understood rules for accepted and expected
behavior
• Each cultural group evolves its own norms; when cultures
collide, their differing norms can confuse or even anger
Social Thinking and Social Influence
Social Influence
Cultural Influences
Variation Over Time
Like biological creatures,
• Cultures vary and compete for resources
• Cultures evolve over time, and may change rapidly;
cultural evolution is far faster than biological evolution
• Cultural changes can be negative or positive
• Cultures shape our lives

Conformity: Complying With Social Pressures
12-4: WHAT IS AUTOMATIC MIMICRY, AND HOW DO
CONFORMITY EXPERIMENTS REVEAL THE POWER OF
SOCIAL INFLUENCE?
Automatic Mimicry
– Behavior is contagious; what we see we often do.
– Chartrand and colleagues (1999) demonstrated the
chameleon effect with college students.
– Automatic mimicry helps people to empathize and feel
what others feel (mood linkage).
– The more we mimic, the greater our empathy, and the
more people tend to like us.
– Suggestibility and mimicry are subtle forms of conformity.
Automatic Mimicry
CONFORMING TO
NONCONFORMITY
Are these students
asserting their individuality
or identifying themselves
with others of the same
microculture?
Social Thinking and Social Influence
Social Influence
Conformity: Complying With Social Pressures
Conformity and Social Norms
• Conformity: Adjusting our behavior or thinking to
coincide with a group standard
• Solomon Asch’s (1955) experiments on conformity
showed that people fear being “oddballs,” and will often
conform with other group members, even though they do
not agree with the group’s decision
• Later investigations have not always found as much
conformity as Asch found, but it is nevertheless a
significant phenomenon
ASCH’S CONFORMITY EXPERIMENTS
Which of the three comparison lines on the left is equal
to the standard line? The photo on the right (from one of
the experiments) was taken after five people, who were
actually working for Asch, had answered, “Line 3.” The
student in the center shows the severe discomfort that
comes from disagreeing with the responses of other group
members.
Social Thinking and Social Influence
Social Influence
Conformity: Complying With Social Pressures
Solomon Asch and others have found that people are
most likely to adjust their behavior or thinking to coincide
with a group standard when:
•
•
•
•
•
•
•
They are made to feel incompetent or insecure
Their group has at least three people
Everyone else agrees
They admire the group’s status and attractiveness
They have not already committed to another response
They know they are being observed
Their culture encourages respect for social standards
Social Thinking and Social Influence
Social Influence
Conformity: Complying With Social Pressures
• Normative social influence: Influence resulting from a
person’s desire to gain approval or avoid disapproval
– Conforming to avoid rejection or to gain social
approval
• Informational social influence: Influence resulting from
one’s willingness to accept others’ opinions as new
information
– Conforming because we want to be accurate
• Conformity rates are generally lower in individualist
cultures than in collectivist cultures, which put a higher
value on honoring group standards

Obedience: Following Orders
12-5: WHAT DID MILGRAM’S OBEDIENCE
EXPERIMENTS TEACH US ABOUT THE POWER OF
SOCIAL INFLUENCE?
• Stanley Milgram’s experiments (1963, 1974) were
intended to see how people would respond to outright
commands.
– Research participants became “teachers” to
supposedly random “learners” and believed they were
subjecting them to escalating levels of electric
shocks.
– More than 60 percent complied fully; other studies
have shown even higher obedience rates.
• People in these studies obeyed orders even when they
thought they were harming another person.
MILGRAM’S FOLLOW-UP OBEDIENCE EXPERIMENT
In a repeat of the earlier experiment, 65 percent of the adult
male “teachers” fully obeyed the experimenter’s commands to
continue. They did so despite the “learner’s” earlier mention of a
heart condition and despite hearing cries of protest after they
administered what they thought were 150 volts and agonized
protests after 330 volts. (Data from Milgram, 1974.)
Social Thinking and Social Influence
Social Influence
Obedience: Following Orders
Obedience in the Milgram experiments was highest
when:
• Person giving orders was nearby and was
perceived to be a legitimate authority figure
• Research was supported by a prestigious
institution
• Victim was depersonalized or at a distance
• There were no role models for defiance
Social Thinking and Social Influence
Social Influence
Obedience: Following Orders
Lessons From the Obedience Studies
– Strong social influences can make people conform to
falsehoods or capitulate to cruelty
– Ordinary people are corrupted by evil situations
– People get to real-life violence in tiny increments (the
foot-in-the-door phenomenon): In any society, great evils
often grow out of people’s compliance with lesser evils
– Milgram (1974): “Ordinary people, simply doing their jobs,
and without any particular hostility on their part, can
become agents in a terrible destructive process”

Social Influence
Group Behavior
12-6: HOW IS OUR BEHAVIOR AFFECTED BY THE
PRESENCE OF OTHERS?
Social Facilitation
• In social facilitation (Triplett, 1898), the presence of
others arouses people, improving performance on easy
or well-learned tasks but decreasing it on difficult ones.
– Our arousal heightens our reactions, strengthening
our most likely response—the correct one on an easy
task but an incorrect one on a difficult task.
• Home advantage for team sports; doing something
we do well in front of a friendly audience
• Crowding effect; performers know that a “good
house” is a full one
Social Thinking and Social Influence
Social Influence
Group Behavior
Social Loafing
– Tendency for people in a group to exert less effort
when pooling their efforts toward attaining a common
goal than when individually accountable
• Three causes of social loafing:
– Acting as part of group and feeling less accountable
– Feeling individual contribution doesn’t matter and is
dispensable
– Slacking off, or free riding on others’ efforts, which is
especially common when there is lack of identification
with the group
Social Thinking and Social Influence
Social Influence
Group Behavior
Deindividuation
– The loss of self-awareness and self-restraint
occurring in group situations that foster arousal and
anonymity.
– Thrives in many different settings.
– When we shed self-awareness and self-restraint—
whether in a mob, at a rock concert, at a ballgame, or
at worship—we become more responsive to the
group experience, whether bad or good.
DEINDIVIDUATION
Deindividuation: During England’s 2011 riots and looting,
rioters were disinhibited by social arousal and by the
anonymity provided by darkness and their hoods and
masks. Later, some of those arrested expressed
bewilderment over their own behavior.
Social Thinking and Social Influence
Social Influence
Group Polarization
12-7: WHAT ARE GROUP POLARIZATION AND
GROUPTHINK, AND HOW MUCH POWER DO WE HAVE
AS INDIVIDUALS?
– Group polarization: The enhancement of a group’s
prevailing inclinations through discussion within the
group.
– Online communication magnifies this effect, for better
(motivating positive social change in protest groups)
and for worse (cementing prejudiced opinions in hate
groups).
GROUP POLARIZATION
• If a group is like-minded,
discussion strengthens
its prevailing opinions.
• Talking over racial issues
increased prejudice in a
high-prejudice group of
high school students and
decreased it in a lowprejudice group (Data
from Myers & Bishop,
1970).
LIKE MINDS NETWORK IN THE BLOGOSPHERE
• Blue liberal blogs link mostly
to one another, as do red
conservative blogs. (The
intervening colors display
links across the liberal
conservative boundary.)
• Each dot represents a blog,
and each dot’s size reflects
the number of other blogs

Internet can be very, very bad,

Social Thinking and Social Influence
Social Influence
Group Polarization
• Groupthink (Janis, 1982): The mode of thinking that
occurs when the desire for harmony within a decisionmaking group overrides a realistic appraisal of
alternatives
• Groupthink is prevented when leaders
– Welcome various opinions, usually in diverse groups
– Invite experts’ critiques of developing plans
– Assign people to identify possible problems
Social Thinking and Social Influence
Social Influence
Group Polarization
The Power of Individuals
• Power of the individual (personal control) and the power
of the situation (social control) interact.
• A committed individual or a small minority with
consistently expressed views may sway the majority.
• The power of one or two individuals to sway majorities is
referred to as minority influence.
Antisocial Relations
Prejudice
12-8: WHAT IS PREJUDICE? WHAT ARE ITS SOCIAL
AND EMOTIONAL ROOTS?
Prejudice
Components
• Means “prejudgment”
• Is an unjustified negative
attitude toward a group
and its members
• Often targets a different
cultural, ethnic, or gender
group
• Beliefs (stereotypes)
• Emotions (for example,
hostility or fear)
• Predispositions to action
(to discriminate)
Antisocial Relations
Prejudice
Prejudice is a negative
attitude.
To believe that obese people are gluttonous, and to feel dislike
for an obese person, is to be prejudiced; prejudice is a negative
attitude. To pass over all the obese people on a dating site, or to
reject an obese person as a potential job candidate, is to
discriminate; discrimination is a negative behavior.
Discrimination is a
negative behavior.
Antisocial Relations
Prejudice
How Prejudiced Are People?
• Prejudice comes as both explicit (overt) and implicit
(automatic) attitudes toward people of a particular ethnic
group, gender, sexual orientation, or viewpoint.
Explicit Ethnic Prejudice
• Explicit ethnic prejudice in North America has decreased
over time.
– Expressed support today for all forms of racial contact,
including the once unpopular idea of interracial dating.
– Overt prejudice has waned; subtle prejudice lingers.
– Prejudice can be automatic and unconscious.
Antisocial Relations
Prejudice
How Prejudiced Are People?
Implicit Ethnic Prejudice
– Implicit racial associations
• Implicit Association Tests results: Even people who
deny racial prejudice may carry negative associations
– Unconscious patronization
• Lower expectations, inflated praise and insufficient
criticism for minority student achievement
– Race-influenced perceptions
• Fatigue can increase automatic reactions that amplify
racial bias
• Unconscious prejudices can cause discrimination even
without conscious discriminatory intent, but monitoring
feelings and actions can help significantly diminish both

Gender Prejudice
• Overt gender prejudice has also declined sharply, but
gender prejudice and discrimination persist
– For example, people tend to perceive their fathers as
more intelligent than their mothers, despite equality
between the sexes in intelligence test scores.
• Gender inequality in wages
– For example, we pay more to those (usually men) who
care for our streets than to those (usually women) who
care for our children.
• Worldwide, more women than men live in poverty, there are
more illiterate women than men, 30 percent of women have
experienced intimate partner violence, and sons are often
valued more than daughters.

How Prejudiced Are People?
Sexual Orientation Prejudice
• Dozens of countries have laws criminalizing same-sex
relationships
• Anti-gay prejudice, though rapidly subsiding in Western
countries, still persists. In national surveys, 39 percent of
LGBT Americans reported having “been rejected by a
friend or family member” because of their sexual
orientation or gender identity. And 58 percent reported
being “subject to slurs or jokes” (Pew, 2013).
• LGBT experience:
– Higher rates of depressive, anxiety, and alcohol use
disorders
– Higher rates of cardiovascular deaths
Antisocial Relations
Prejudice
Social Roots of Prejudice
• Why does prejudice arise? Social inequalities and divisions
are partly responsible.
Social Inequalities
• Social inequalities: The privileged often developed attitudes
that justify the status quo.
• Just-world phenomenon: Good is rewarded and evil is
punished.
• Stereotypes rationalize inequalities.
• Victims of discrimination may react in ways that feed
prejudice, in a classic blame-the-victim dynamic:
– Circumstances of poverty breed a higher crime rate, for
example, which then can be used as a justification for
discrimination.

Prejudice
Social Roots of Prejudice
Us and Them: Ingroup and Outgroup
• Through social identities people associate themselves
with certain groups and contrast ourselves with others.
• Evolution prepares people to identify with a group:
– Ingroup: “us” – people with whom we share a
common identity
– Social definition of who we are includes who we are
not
– Outgroup: “them” – those perceived as different or
apart from our group
– Ingroup bias: Favoring of our own group
Antisocial Relations
Prejudice
Emotional Roots of Prejudice
• Scapegoat theory proposes that when things go wrong,
finding someone to blame can provide an outlet for anger
• Philip Zimbardo (2001) on terrorism: “Fear and anger create
aggression, and aggression against citizens of different
ethnicity or race creates racism and, in turn, new forms of
terrorism.”
• Prejudice levels tend to be high among economically
frustrated people
• In experiments, a temporary frustration increases prejudice
• Negative emotions feed prejudice
Antisocial Relations
Prejudice
Cognitive Roots of Prejudice
12-9: WHAT ARE THE COGNITIVE ROOTS OF
PREJUDICE?
• Stereotyped beliefs are a by-product of how we
cognitively simplify the world.
Forming Categories
– Humans categorize people by race: mixed-race
people often identified by minority identity.
– Similarities of others overestimated during
categorization, creating “We” and “They.”
– Other-race effect (also called the cross-race effect
and the own-race bias): The tendency to recall faces
of one’s own race more accurately than faces of other
races.
CATEGORIZING MIXED-RACE PEOPLE
When New Zealanders quickly classified 104 photos by
race, those of European descent more often than those
of Chinese descent classified the ambiguous middle two
as Chinese (Halberstadt et al., 2011).

Antisocial Relations
Prejudice
Cognitive Roots of Prejudice
Remembering Vivid Cases
• We often judge the frequency of events by instances that
come readily to mind.
• Vivid—violent, for example—cases are more readily
available to our memory and feed our stereotypes.
Believing the World Is Just
• If the world is just, people must get what they deserve.
• Hindsight bias often comes into play, promoting a blamethe-victim mentality (which also reassures people that
terrible crimes couldn’t happen to them).
• People also have a basic tendency to justify their
culture’s social systems.
Antisocial Relations
Aggression
12-10: HOW DOES PSYCHOLOGY’S DEFINITION OF
AGGRESSION DIFFER FROM EVERYDAY USAGE?
WHAT BIOLOGICAL FACTORS MAKE US MORE
PRONE TO HURT ONE ANOTHER?
– Aggression: Any physical or verbal behavior
intended to harm someone physically or emotionally
– Examples of aggressive behavior: passing along
vicious rumors, bullying in person or online, physical
attack
– Aggressive behavior results from interaction of
biology and experience
Antisocial Relations: Aggression
The Biology of Aggression
• Biology influences aggression at three levels.
Genetic Influences
• Evidence from animal studies and twin studies; the
male Y chromosome is a genetic marker, as is the
MAOA gene
– People who have low MAOA gene expression tend
to behave aggressively when provoked
Neural Influences
• Neural systems facilitate or inhibit aggression when
provoked
• Aggression more likely to occur with frontal lobe
damage
Biochemical Influences
• Testosterone influences the neural systems that control
aggression
• Alcohol effect—unleashes aggressive responses (even
just thinking you’ve consumed it has an effect)
Antisocial Relations: Aggression
Psychological and Social-Cultural Factors in
Aggression
12-11: WHAT PSYCHOLOGICAL AND SOCIAL-CULTURAL
FACTORS MAY TRIGGER AGGRESSIVE BEHAVIOR?
Aversive Events
– Frustration-aggression principle: Frustration creates
anger, which can spark aggression
Reinforcement, Modeling, and Self-Control
– Previous reinforcement for aggressive behavior,
observing an aggressive role model, and poor selfcontrol may all trigger aggression
– Hot temperatures, physical pain, personal insults, foul
odors, cigarette smoke, crowding, and a host of other
aversive stimuli may also evoke hostility
– “Manly honor” and “culture-of-honor” traditions may
encourage aggressive behavior
Antisocial Relations: Aggression
Psychological and Social-Cultural Factors in
Aggression
Media Models for Violence
• Media portrayals of violence provide social scripts that
children learn to follow.
• Viewing sexual violence contributes to greater
aggression toward women.
• Playing violent video games increases aggressive
thoughts, emotions, and behaviors.

Do Violent Video

Scripts for Violence?
• Nearly 400 studies of
130,000 people
suggest video games
can prime aggressive
thoughts, decrease
empathy, and increase
aggression.
• Some researchers
dispute this finding and
note other factors they
say may be more
important: Depression,
family violence, and
peer influence.
COINCIDENCE OR CAUSE? In 2011,
Norwegian Anders Behring Breivik
bombed government buildings in Oslo,
and then went to a youth camp where
he shot and killed 69 people, mostly
teens.

The Psychology of Attraction
12-12: WHY DO WE BEFRIEND OR FALL IN LOVE WITH
SOME PEOPLE BUT NOT OTHERS?
Proximity
• Proximity—geographic nearness—is friendship’s most
powerful predictor
• Provides opportunity for aggression or friendship, but
much more often breeds the latter
• Mere exposure effect: The phenomenon that repeated
exposure to novel stimuli increases liking of them
Prosocial Relations

The Psychology of Attraction
Modern Matchmaking
• Internet-formed friendships and romantic relationships are on
average slightly more likely to last and be satisfying.
• A national U.S. survey showed that nearly a quarter of
heterosexual and two-thirds of same-sex couples met online.
• Speed-dating
• For many people, 4 minutes sufficient to form a feeling
about a conversational partner and to register whether the
partner likes them.
• People who fear rejection often elicit it.
• Choices may be more superficial, especially given many
options.
• Women tend to be more choosy than men.
Prosocial Relations
Attraction
The Psychology of Attraction
Physical Attractiveness
• Affects first impression
• Predicts frequency of dating and popularity
• Is influenced by cultural ideals and personal feelings.
Similarity
• Includes shared attitudes, beliefs, interests, age, religion,
race, education, intelligence, smoking behavior, and
economic status
The reward theory of attraction holds that we will like those
whose behavior is rewarding to us, including those who are
both able and willing to help us achieve our goals.
WHAT DO WE MEAN BY “ATTRACTIVE”?
The answer varies by culture and over time.
• Some adult physical features, such as a youthful form
and symmetrical face, seem attractive everywhere.
• Appealing traits enhance feelings of physical
attractiveness.
Prosocial Relations
Attraction
Romantic Love
12-13: HOW DOES ROMANTIC LOVE TYPICALLY CHANGE
AS TIME PASSES?
Passionate Love
• The two-factor theory of emotion can help us
understand passionate love:
– Emotions have two ingredients: physical arousal
and cognitive appraisal.
– Arousal from any source can enhance an
emotion, depending on how we interpret and
label the arousal.
• Sexual desire + a growing attachment = the
passion of romantic love.
Prosocial Relations
Attraction
Romantic Love
Companionate Love
– Although the desire and attachment of passionate love
often endure, the intensity generally fades into a steadier
companionate love—a deep, affectionate attachment
– Passion-facilitating hormones (testosterone, dopamine,
adrenaline) give way to another, oxytocin, that supports
feelings of trust, calmness, and bonding
– Equity is an important key to satisfying and enduring
relationship
– Self-disclosure deepens intimacy
– A third key to enduring love is positive support
Prosocial Relations
Altruism
12-14: WHEN ARE PEOPLE MOST—AND LEAST—
LIKELY TO HELP?
• Altruism is an unselfish concern for the welfare of others.
• Altruism became a major concern of social psychologists
after an especially vile act. On March 13, 1964, a stalker
repeatedly stabbed Kitty Genovese, then raped her as she
lay dying outside her Queens, New York, apartment at
3:30 a.m. Genovese’s screams for help attracted attention,
but no one called the police until 3:50 a.m., after the
attacker had already fled.
Prosocial Relations
Altruism
Bystander Intervention
Bystander Effect
– People are most likely to help when they notice an
incident, interpret it as an emergency, and assume
responsibility for helping (Darley and colleagues).
– When more people share responsibility for helping, there
is a diffusion of responsibility.
– The bystander effect is the tendency for any given
bystander to be less likely to give aid if other bystanders
are present.
Prosocial Relations
Altruism
Bystander Intervention
• Odds for deciding to help are increased when
– The person appears to deserve help
– The person is in some way similar to us
– The person is a woman
– We have just observed someone else being helpful
– We are unhurried or in a good mood
– We are feeling guilty
– We are focused on others and not preoccupied

The Norms for Helping
12-15: HOW DO SOCIAL EXCHANGE THEORY AND SOCIAL
NORMS EXPLAIN HELPING BEHAVIOR?
Why do we help?
• Social exchange theory
– Maximizing rewards and minimizing costs (accountants
call it cost-benefit analysis; philosophers call it
utilitarianism; psychologists call it social exchange theory)
• Reciprocity norm
– Expectation that people will respond favorably to each
other by returning benefits for benefit
• Social-responsibility norm
– Expectation that people should help those who depend on
them
Prosocial Relations
Peacemaking
Elements of Conflict
12-16: HOW DO SOCIAL TRAPS AND MIRROR-IMAGE
PERCEPTIONS FUEL SOCIAL CONFLICT?
Conflict
– Perceived incompatibility of actions, goals, or ideas in
which people become enmeshed in potentially
destructive processes that often produce unwanted
results
– Among these processes are social traps and distorted
perceptions
Prosocial Relations
Peacemaking
Elements of Conflict
Social Traps
• Situation in which conflicting parties, by each pursuing their
self-interest rather than the good of the group, become
caught in mutually destructive behavior
• Social traps harm our collective well-being
• Social traps challenge us to reconcile our right to pursue our
personal well-being with our responsibility for the well-being
of all. Psychologists have explored ways to convince people
to cooperate—agreed-upon regulations, better
communication, and awareness of our responsibilities
toward community, nation, and the whole of humanity
Prosocial Relations
Peacemaking
Elements of Conflict
Enemy Perceptions
• Psychologists have noted that those in conflict have a
curious tendency to form diabolical images of one
another.
• Mirror-image perceptions: Mutual views often held by
conflicting people, as when each side sees itself as
ethical and peaceful and views the other side as evil and
aggressive.
• Self-fulfilling prophecy: A belief that leads to its own
fulfilment.
• As enemies change, so do perceptions (for example, a
negative American view of Japan during WWII later
became positive).
Prosocial Relations
Peacemaking
Promoting Peace
12-17: HOW CAN WE TRANSFORM FEELINGS OF
PREJUDICE, AGGRESSION, AND CONFLICT INTO
ATTITUDES THAT PROMOTE PEACE?
Research indicates that in some cases contact and
cooperation can be transformational.
Contact
– Most effective when contact is free of competition and
equal status exists.
– Across a quarter-million people studied in 38 nations,
friendly contact with ethnic minorities, older people,
and people with disabilities has usually led to less
prejudice.
– Contact is not always enough. Also important are
cooperation, communication, and conciliation.
Prosocial Relations
Peacemaking: Promoting Peace
Cooperation
•Cooperative contact, not contact alone,
reduces conflict.
•A shared predicament or superordinate goal can
have a unifying effect.
•Experiments with teens in 11 countries
confirm that cooperative learning can maintain
or enhance student achievement.
•When real-life conflicts become intense, a
third-party mediator may facilitate muchneeded communication.
Communication •Mediators can help each party to voice its
viewpoint and to understand the other’s needs
and goals; change a competitive win-lose
orientation to a cooperative win-win one.
Conciliation
•GRIT (Graduated and Reciprocated Initiatives
in Tension-Reduction) is alternative to conflict,
to war or surrender.
