Social Psychology
Social Psychology
• Social Psychology – study of how a person’s thoughts, feelings, and behavior are
influenced by others and the environment. • Sense of Self – Your sense of who you are in
relation to others.
– Unique sense of identity, influenced by social,
Person Perception
• Person Perception – Mental processes we use to make judgments or drawn conclusions
about characteristics or motives of others.
– Done rapidly, almost instantly. Judge factors such
as attractiveness, likeability, competence, trustworthiness, etc…
Person Perception
• Principle 1: Your reactions to others are
determined by your perceptions of them, not who they really are.
• Principle 2: Your self-perception also
Person Persuasion
• Principle 3: Your goals in a particular situation determine the amount and kinds of
information you collect about others.
Attribution
• Attribution – Inferring the causes of people’s behavior, including our own.
– Helpful in coming to conclusions and guiding your
own behavior.
• Fundamental Attribution Error – Tendency to attribute the behaviors of others to internal or personal characteristics, while ignoring the
Attribution
• Hindsight Bias – Tendency to overestimate
one’s ability to have foreseen or predicted the outcome of an event.
– “I could have told you that would happen” or “I
Attribution
• Just-World Hypothesis – Assumption that the world is fair and that therefore people get
what they deserve and deserve what they get.
• Self-Serving Bias – Tendency to attribute
Attitudes
• Attitude – Learned tendency to evaluate an object, person,
or issue, in a particular way.
– Can be positive, negative, or ambivalent – Contains three components:
• Cognitive – Beliefs, thoughts, ideas about the attitude object • Behavioral – Predisposition to act in a particular way
• Emotional – Feelings and emotions about the attitude object
• Intuitively, people assume that we act in accordance
without attitudes. However, this is not always the case.
– I.e. you may generally have a negative attitude towards cheating
Attitudes
• When are people more likely to behave in
accordance with our attitudes:
– When there is a favorable outcome for doing so. – When your attitudes are extreme or frequently
expressed.
– When your attitudes have been formed through direct
experience.
– When you are very knowledgeable about the subject. – When you have a vested interest in the subject and
Cognitive Dissonance
• Developed by Philip Zimbardo (1965).
• Cognitive Dissonance – An unpleasant state of psychological tension or anxiety (dissonance) that occurs when two thoughts or perceptions (cognitions) are inconsistent.
– Generally this tension is so unpleasant that we are
Cognitive Dissonance
• Cognitive Dissonance commonly occurs in situations where your behavior and your attitudes are in conflict.
– In this situation you have two opposing cognitions: • Your original attitude versus the realization that your
behavior contradicts that attitude.
– Since we can’t go back in time and change our behaviors, what can we change to reduce the dissonance?
Cognitive Dissonance
• Example:
– Researcher has participants perform menial tasks (sorting
papers by alphabetical order) for 3 hours.
– After the experiment the participants are paid various amounts
of money to lie to the next participant in the study.
• ½ participants get $50
• ½ participants get 50 cents.
– The researcher asks them to lie about their attitudes about the
experiment to the next participant waiting in the lobby and tell them they enjoyed the experiment.
– After lying, how do you think the two groups ($50 vs 50 cents)
Cognitive Dissonance
• Result:
– After lying participants who were paid $50
maintain a negative attitude toward the study but say they lied because of the money
– Participants who were paid 50 cents often report a
similar attitude as the one they lied to the next participant with – a generally positive attitude towards the experiment
Implicit and Explicit Attitudes
• Explicit Attitudes – Conscious preferences and biases towards
attitude objects that is often expressed outwards.
– Saying “I don’t like to drink milk because it is weird to drink milk from
another animal” is an explicit attitude. You are aware of the attitude, can express it, and understand why the attitude exists.
• Implicit Attitudes – Preferences and biases toward attitude
objects that are automatic, spontaneous, unintentional, and generally unconscious.
• Both Implicit and Explicit attitudes play a significant role in
prejudice.
– A negative attitude toward people belonging to a specific social group.
Overcoming Prejudice
• The Robbers Cave Experiment: – Headed by Mazuafer Sherif (1961)
– Randomly assigned boys at a summer camp into two
groups.
– The two groups arrived in separate busses and lived in
separate parts of the camp.
• Separated into the “Eagles” and the “Rattlers”.
– After a week of separation between the groups, the
researchers arranged for them to meet in a series of competitive games.
Overcoming Prejudice
• The two groups immediately became rivals as a result of competition (and competition for resources/rewards).
– Competition created an extremely intense rivalry: • Eagles burned the Rattlers’ flag, Rattlers trashed Eagles’
cabin, etc…
Overcoming Prejudice
• The researchers tried to bring them together by having them engage under peaceful
circumstances.
– Watching a movie together, eating in the same
dining hall, etc…
– DID NOT WORK – actually made it easier for the
two groups two fight with each other (i.e. massive food fights during dinner).
Overcoming Prejudice
• Finally, the researchers created a series of
situation in which the two groups needed to cooperate to achieve a common goal.
– I.e. the researchers sabotaged the water supply and
the two groups had to work together to fix it.
• Through joint efforts, rivalry diminished and the
groups became good friends.
• Working together to achieve a common goal
Conformity
• Conformity – Adjusting your opinions, judgment,
or behavior so that it matches other people, or the norms of a social group or situation.
– Conformity is extremely powerful in manipulating
attitudes, perception, etc…
• Everyone conforms to some degree, it is
inescapable.
– However, how far will we conform just to be in sync
Conformity
• Solomon Asch wanted to answer this question by
asking his own: Would people still conform to the group if the group opinion was clearly wrong?
• 76% of individuals conformed with group judgment
Conformity
• Why did people conform in such a way?
– Two likely factors:
• Normative Social Influence – Behavior that is motivated
by the desire to gain social acceptance and approval.
– Leads to directly conforming to achieve acceptance into the group.
• Informational Social Influence – Behavior that is
motivated by the desire to be correct.
Obedience
• Stanley Milgram developed one of the most
influential studies in psychology to understand the concept of obedience.
Obedience
• Milgram’s Study: https://www.youtube.com/watch?v=y6GxIuljT3w
• Asked psychiatrists, college students,
Obedience
• Without forcefully keeping the “teacher” there, and
by only delivering statements that expect obedience as well as looking like an “authority” figure, 65% of “teachers” administered the maximum shock value.
• For comparison: When the “teacher” is required to
Obedience
• When teachers were allowed to act as their own authority and freely choose the shock level, 95% of them did not go above 150v.
– Indicates they are responding to the orders from
an authority figure.
• “Teachers” were more likely to defy the
Helping Behavior
• Kitty Genovese
– Assaulted outside of her apartment building.
– Was stabbed by the assailant before he walked off
– Assailant returns and stabs Kitty a second time before driving away.
– Assailant returns again and stabs her to death at foot of her steps outside her apartment building.
– An estimated 38 people witnessed the murder, spanning 3 different attacks over 30 minutes without calling the police or attempting to help her individually.
Helping Behavior
• Why did nobody attempt to help?
– Bystander Effect – The greater the number of people
present, the less likely each individual is to help someone in distress. Often due to a diffusion of
responsibility, but can occur for other reasons as well (i.e. “If nobody else is helping then maybe it isn’t
actually an emergency).
– Diffusion of Responsibility – The presence of other
Helping Behaviors
• Factors that increase the likelihood of bystanders helping:
– “Feel good, do good” effect. – Feeling guilty
– Seeing others who are willing to help
– Perceiving the other person as deserving help – Knowing how to help
Helping Behaviors
• Factors that decrease the likelihood of bystanders helping:
– The presence of other people – Diffusion of responsibility
– Being in a big city or very small town – Vague or ambiguous situations
– When the personal costs for helping outweigh the
Influence of Groups on Individual Behavior
• Social Loafing – People occasionally expend less effort on a task when it is a group effort.
– The grater number of people involved in a
collective effort, the lower each individual’s input.
– How to decrease social loafing: • Group with people you know.
• Make the social loafer a “highly valued” member of the
group.
• Make the task that someone is loafing on “meaningful”
Influence of Groups on Individual Behavior
• Social Facilitation - Tendency for the presence of other people to enhance individual
performance.
– When other people are around, we generally
perform tasks better.
– For example: When a group watches and applauds
Influence of Groups on Individual Behavior
• Deindividuation – Reduction of self-awareness
and inhibitions that can happen when a person is part of a group whose members feel
anonymous.
– Anonymity in groups can lead individuals to reduce
inhibitions and lead to engaging in the “group’s” behaviors, rather than our own.
• For example: Deindividuation is common in riots where people think they are anonymous, thus joining the
