Social Influence

Examines how other people and the social forces they create influence an individual’s behavior

Why We Conform

Conformity is defined as a change in behavior, belief, or both to conform to a group norm as a result of real or imagined group pressure

Although “conformity” has negative connotations in Western cultures, some conformity is needed for society to function For instance, in the military, conformity is essential

because in a time of war, soldiers cannot each do his or her own thing while in battle

The Sherif Study and Informational Social Influence

Participants, who thought they were in a visual perception experiment, were placed in a completely dark room and exposed to a stationary point of light, and their task was to estimate the distance this light moved The light never moved; it was an illusion

called the autokinetic effect, whereby a stationary point of light appears to move in a dark room because there is no frame of reference and our eyes spontaneously move

The Sherif Study and Informational Social Influence

During the first session, each participant was alone in the dark room when making their judgments But during the next three sessions, they were in the room

with two other participants and could hear each others estimates of the illusory light movement

The average individual estimates varied greatly during the first session During the next three sessions, though, the individual

estimates converged on a common group norm A year later, participants were brought back and made

estimates alone; yet, these estimates remained at the group norm

The Sherif Study and Informational Social Influence

This pattern of results suggests the impact of informational social influence, which is influence that stems from our desire to be correct in situations in which the correct action of judgment is uncertain and we need information

When a task is ambiguous or difficult and we want to be correct, we look to others for information

For instance, when visiting a foreign culture, it is usually a good idea to watch how the people living in that culture behave in various situations because they provide information to outsiders on how to behave in that culture

The Asch Study and Normative Social Influence

In Asch’s study, the visual judgments were easy visual discriminations involving line-length judgments Specifically, participants had to judge which one of three

lines was the same length as a “standard line”

In this study, the correct answer/behavior was obvious Indeed, when making such judgments alone, almost no one

made any mistakes

An Example of Asch’s Line-Length Judgment Task

The Asch Study and Normative Social Influence

In Asch’s study, there were other “participants” who were in fact experimental confederates, part of the experimental setting On each trial, judgments were made orally, and Asch

structured the situation so the experimental confederates responded before the true participant

These experimental confederates arranged to make mistakes on certain trials in an effort to see how the “real” participant would respond when asked to make line length judgments

The Asch Study and Normative Social Influence

About 75% of the participants gave an obviously wrong answer at least once, and overall, conformity occurred 37% of the time

This conformity occurred despite the fact the “correct” answer, unlike in Sherif’s study, was obvious

The Asch Study and Normative Social Influence Asch’s results illustrate the power of

normative social influence, influence stemming from our desire to gain the approval and to avoid the disapproval of other people In essence, we change our behavior to

meet the expectations of others and to gain the acceptance of others

If the line-length judgments were extremely difficult, and the correct answers were not clear, then informational social influence would likely lead to even higher levels of conformity

Situational Factors that Impact Conformity

If the group is unanimous, conformity will increase Asch found that the amount of conformity

decreased considerably if just one of the experimental confederate participants gives the correct answer, or even an incorrect answer that is different from the incorrect answer all other confederates gave

As one person is “different” somehow, it allows other people to avoid conforming.

Situational Factors that Impact Conformity

The mode of responding is also critical Secret ballots lead to less conformity than public,

verbal reports The status of group members intervenes

More conformity is observed from a person that is of lesser status than the other group members or is attracted to the group and wants to be part of it

Why We Comply

Compliance is acting in accordance to a direct request from another person or group Occurs in many facets of life (e.g., salespeople,

fundraisers, politicians, and anyone else who wants to get people to say “yes” to their requests)

Compliance Techniques

Foot-in-the-doorFoot-in-the-door

Door-in-the-faceDoor-in-the-face

Low-ballLow-ball

That’s-not-allThat’s-not-all

The Foot-in-the-Door Technique

Here, compliance to a large request is gained by prefacing it with a very small, almost mindless request The tendency is for people who have complied

with the small request to comply with the next, larger request

In Freedman and Fraser’s (1966) classic study, some people were asked directly to put a large ugly sign urging careful driving in their front yards Almost all such people refused the large ugly sign However, some other people were first asked to

sign a petition urging careful driving Two weeks after signing this petition (that is,

agreeing to a rather small request), the majority of these latter people agreed to allow the large ugly sign in the front yards

The Foot-in-the-Door Technique

This technique seems to work because our behavior (complying with the initial request) affects our attitudes, leading us to be more positive about helping and to view ourselves as generally charitable people In addition, once we have

made a commitment (such as signing a safe driving petition), we feel pressure to remain consistent (by putting up the large ugly sign) with the earlier action

The Foot-in-the-Door Technique

The technique was used by the Communist Chinese in the Korean War on prisoners of war Many prisoners returning home after the war praised

the Chinese Communists because while in captivity, the prisoners did small things such as writing out questions and then providing the pro-Communist answers, which often they just copied from a notebook

Such minor actions induced more sympathy for the Communist cause

The Door-in-the-Face Technique

The opposite of the foot-in-the-door technique

Compliance is gained by starting with a large unreasonable request that is turned down, and then following it with a more reasonable smaller request

It is the smaller request that the person making the two requests wants someone to comply with

The Door-in-the-Face Technique

For instance, a teenager may ask his parents if he can have a new sports car for his 16th birthday His parents are likely to refuse Then, the teenager asks his parents to help him

pay for a used 20-year-old car, which is what he wanted his parents to help him with all along

The Door-in-the-Face Technique

The success of the door-in-the-face technique is due to our tendency toward reciprocity, that is, making mutual concessions The person making the requests appears to have

made a concession by moving to the much smaller request so shouldn’t we reciprocate and comply with this smaller request?

The Low-Ball Technique

Compliance to a costly request is achieved by first getting compliance to an attractive, less costly request, but then reneging on it This is similar to the foot-in-the-door technique in that a

second larger request is the one desired all along Low-balling works because many

of us feel obligated to go through with the deal after we have agreed to the earlier request, even if the first request has changed for the worse We want to remain consistent in

our actions

The That’s-Not-All Technique

People are more likely to comply to a request after a build-up to make the request sound “better” Often in infomercials on TV, for example, the announcer

says “But wait, that’s not all, there’s more!” and the price is lowered or more merchandise is added to sweeten the deal, usually before you even have a chance to respond

Similarly, a car salesperson is likely to throw in additional options as bonuses before you can answer yes or no to a price offered

The That’s-Not-All Technique

As in the door-in-the-face technique, reciprocity is at work The seller has done you a favor (thrown in bonus

options, lowered the price), so you “should” reciprocate by accepting the offer (i.e., comply)

Four Compliance Techniques

Why We Obey

Obedience is following the commands of a person in authority Obedience is good in some instances, such as

obeying societal laws Obedience is bad in other instances, such as in

the My Lai massacre during the Vietnam War, when American soldiers were ordered to shoot innocent villagers (and they did so)

Why We Obey

Milgram’sExperiment

Milgram’sExperiment

The “Astroten” Study

The “Astroten” Study

SituationalFactors

SituationalFactors

Milgram’s Basic Experimental Paradigm

Stanley Milgram’s obedience studies were done primarily at Yale University in the early 1960s

Imagine that you have volunteered to be in an experiment on learning and memory You show up at the assigned time and

place, and there is the experimenter and another participant there

Milgram’s Basic Experimental Paradigm

The experimenter tells you both that the study is examining the effects of punishment by electric shock on learning, and specifically learning a list of word pairs One of the participants will be the teacher

and the other participants will be the learner You draw slips for these roles, and you

draw the slip of the teacher, so the other participant will be the learner

Milgram’s Basic Experimental Paradigm

You accompany the learner to an adjoining room where he is strapped into a chair with one arm hooked up to the shock generator in the other room The shock levels in the

study range from 15 volts to 450 volts

The experimenter gives you, the teacher, a “test shock” of 45 volts so that you know how intense various shock levels will be

Milgram’s Basic Experimental Paradigm

You return to your room with the shock generator You notice that on the shock generator, each switch has

a label for each level of shock, starting at 15 volts and going to 450 volts in 15-volt increments

There are also some verbal labels below the switches, “Slight Shock,” “Very Strong Shock,” “Danger: Severe Shock,” and under the last two switches “XXX” in red.

Each time the learner makes a mistake, he is to receive a shock, which should increase one 15-volt level for each additional mistake

Milgram’s Basic Experimental Paradigm

As the experiment begins, the learner makes some mistakes, and you as the teacher throw the shock lever as instructed by the experimenter At 120 volts, the learner cries out that the shocks really hurt

As the learner continues to make mistakes, he protests and says that he has a heart condition and that he refuses to continue with the experiment, demanding to be let out of his chair

After a 330-volt shock, he fails to respond with any protest

You turn to the experimenter to see what to do, and the experimenter says to treat no response as an incorrect response and continue with the experiment

Milgram’s Initial Obedience Finding

Before this experiment was run, Milgram asked various types of people what they and other people would do Most people thought people would stop at

relatively low shock levels Psychiatrists said that

maybe one person in a thousand would go to the end of the shock generator

Milgram’s Initial Obedience Findings

In reality, almost two out of every three participants (65%) continued to obey the experimenter and administered the maximum possible shock of 450 volts This is particularly disturbing because the learner had

mentioned a heart condition before the experiment started and during his protests

It is important to realize that the learner was a confederate who was programmed to make mistakes and was never really shocked But the teacher thought that he was administering real

shocks because of real mistakes

InterpretingMilgram’s Findings

The difference between what we say we will do and what we actually do illustrates the power of situational social forces on our behavior

The foot-in-the-door technique was used because participants started off giving very mild shocks (15 volts) and increased the voltage relatively slowly The learner did not protest these early

shocks, and the teacher had obeyed several times before the learner started his protests

InterpretingMilgram’s Findings

It should be noted that later studies with female participants found similar obedience rates, and other researchers have replicated Milgram’s basic finding in many different cultures (e.g., Jordan, Spain, Italy, and Australia)

Situational Factors that Impact Obedience

The physical presence of the experimenter (the person with authority) If the experimenter left the room and gave commands

over the telephone, maximum obedience (administering the highest shock level) dropped to 21%

The physical closeness of teacher and learner Milgram made the teacher and learner closer by

having them both in the same room instead of different rooms, and maximum obedience declined to 40%

It dropped to 30% when the teacher had to directly administer the shock by forcing the learner’s hand onto a plate

Situational Factors that Impact Obedience

Setting of the study Instead of conducting the research at prestigious Yale

University, Milgram did the study in a run-down office building in Bridgeport, Connecticut

Here, he found a 48% obedience rate; thus, the setting did not influence obedience as much as presence of the experimenter or closeness of the teacher and learner

Experimenter unanimity Milgram set up a situation with two experimenters who at

some point during the experiment disagreed One said to stop the experimenter, while the other said to

continue In this case, when one of the people in authority said to

stop, all of the teachers stopped delivering the shocks

Situational Factors that Impact Obedience

Teacher responsibility In another variation, Milgram had the teacher only

push the switch on the shock generator to indicate to another teacher (an experimental confederate) in the room with the learner how much shock to administer

Here, 93% of the participants obeyed the experimenter to the maximum shock levels

Results for Some of Milgram’s Experimental Conditions

The “Astroten” Study

Participants were real nurses on duty alone in a real hospital ward

Each nurse received a call from a person using the name of a staff doctor not personally known by the nurse The doctor ordered the nurse to give a dose

exceeding the maximum daily dosage of an unauthorized medication, called “Astroten” to a real patient in the ward

The “Astroten” Study

This situation violated many hospital rules: Medication orders need to be given in person

and not over the phone It was a clear overdose The medication was unauthorized

Of the 22 nurses phoned, 21 did not question the order and went to give the medication, but were intercepted before actually giving it to the patient

The “Astroten” Study

A separate sample of 33 nurses were asked about this situation and what they would do if they were placed it in All but 2 said they would NOT obey the doctor’s

order, again demonstrating the difference between what we think we will do and what we actually do in a given situation

The Jonestown Massacre

In 1978, more than 900 people who were members of Reverend Jim Jones’s religious cult in Jonestown, Guyana committed mass suicide by drinking cyanide-laced Kool Aid

These were Americans who moved to South America from San Francisco in 1977

Using various compliance techniques, Jones developed unquestioned faith as the cult leader and discouraged individualism

The Jonestown Massacre

Using the foot-in-the-door technique, he was able to increase financial support required of each member until they had turned over essentially everything they owned

He had recruiters ask people walking by to help the poor When they refused, the recruiters then asked them just to donate

five minutes of time to put letters in envelopes (door-in-the-face) When given information about other charitable work, having agreed

to this small task, people returned later as a function of the consistency aspect of the foot-in-the-door technique

Informational social influence was also at work, as being moved from San Francisco to Guyana created an uncertain environment in which followers would look to others to guide their own actions

BystanderEffect

Social Facilitation

The emergence of a dominant response on a task (for which a person is individually responsible) due to social arousal, leading to improvement on simple or well-learned tasks and worse performance on complex or unlearned tasks when other people are present

This effect occurs because that the presence of others increases physiological arousal, and under conditions of increased arousal, people tend to give whatever response is most dominant

Social Facilitation

For example, for a professional basketball player, shooting free throws is a simple, easy task Thus, such a person would shoot free

throws better when other people are around and watching than when shooting alone

However, for someone not good at shooting a basketball, s/he will shoot even more poorly when other people are around and watching than when shooting alone

Social Loafing and the Diffusion of Responsibility

Social loafing occurs when people are pooling their efforts to achieve a common goal It is the tendency for people to exert less effort

when working toward a common goal in a group than when individually accountable

Social Loafing and the Diffusion of Responsibility

A major reason why social loafing occurs is the diffusion of responsibility, which means that the responsibility for a task is spread across all members of the group so individual accountability is lessened The larger the group, the less likely it is that a social

loafer will be detected and the more responsibility for the task gets diffused across group members

However, for groups in which individual contributions are identifiable and evaluated, social loafing decreases

Social Loafing and the Diffusion of Responsibility

For instance, in a group project for a shared grade, social loafing would decrease if each group member is assigned and responsible for a specific part of the project

The Bystander Effect

In 1964, Kitty Genovese was returning home from work late one night when she was attacked in front of her apartment building

She screamed for help, and many apartment residents, at least 38 of them, heard her cries for help and looked out their windows

The attacker fled, but no one intervened

The attacker returned and continued his assault for another 35 minutes before finally murdering her

The first person in the apartment complex did not call the police until after Kitty had been killed

The Bystander Effect

Many media people said this incident illustrated “big city apathy” However, experiments by social psychologists

suggested that it was more diffusion of responsibility The bystander effect holds

that the probability of an individual helping in an emergency is greater when there is only one bystander than when there are many bystanders

The Bystander Effect

Darley and Latané (1968) did an experiment in which college students were ostensibly going to participate in a round-robin discussion of college adjustment problems, and that this discussion would occur over an intercom system Thus, participants could only hear each other, not see

each other The experimenter says he will not listen to the

conversation so participants won’t feel at all inhibited

The Bystander Effect

After each student gets a turn to talk, the first student gets to talk again, but he seems to be very anxious Suddenly, he starts having a seizure and cries

out for help What would a participant do in this situation?

The Bystander Effect

Whether or not a participant helped depended on how many other individuals the participant thought were available to help the student having the seizure The researchers manipulated the number of other people

present (either 0, 1 or 4 others present) In reality no one else was present, the supposed other

participants were merely tape recordings When no one else was thought to be present, 85%

of the participants tried to help the person, whereas only 31% of the participants did so when 4 other people were supposedly present

The Bystander Effect

The probability of helping decreased as the responsibility for helping was diffused across more participants

In the case of Kitty Genovese, there were 38 bystanders who could see each other staring out of their windows with some turning on their lights Responsibility was diffused across all of them, with no one

person assuming full responsibility to help Kitty might have received help and

possibly lived had there been only one person available to give help (i.e., call the police) rather than 38!

Deindividuation

The loss of self-awareness and self-restraint in a group situation that fosters arousal and anonymity

Deindividuated people feel less restrained, so may forget their moral values and act spontaneously without thinking

Diffusion of responsibility also plays a role in deindividuation because of the anonymity of the group situation

Group Polarization & Groupthink

Apply to more structured, task-oriented group situations

Group Polarization

The strengthening of a group’s prevailing opinion about a topic following group discussion of the topic

For instance, if students who don’t like a particular class all start talking about that class, they will leave the discussion disliking the class even more because each student may provide different reasons for disliking the class Each member learns new reasons for his or her

dislike of the class

Group Polarization

In addition, normative social influence is at work We want others to like us, so we express

stronger views on a topic to gain approval from others in the group

For instance, students who belong to fraternities or sororities tend to be more politically liberal, and this difference grows during college because group members reinforce and polarize each other’s views

Groupthink

A mode of group thinking that impairs decision making The desire for group harmony overrides a

realistic appraisal of the possible decisions Leads to an illusion of infallibility, the belief that

the group cannot make mistakes

Groupthink

Examples of groupthink in history include the failure to anticipate Pearl Harbor, the Bay of Pigs invasion of Cuba, and the Space Shuttle’s Challenger and Columbia disasters In the case of the Space

Shuttle Columbia, NASA apparently ignored safety warnings from engineers about possible technical problems

How We Think about Our Own and Others’ Behavior

How We Make Attributions

How Our Behavior Affects Our Attitudes

Attribution

The process by which we explain our own behavior and the behavior of others

That is, what do we think are the causes of our behavior and the behavior of others?

How We Make Attributions

An internal attribution means explaining behavior in terms of a person’s disposition/personal characteristics

An external attribution means explaining behavior in terms of a person’s circumstances/situation For example, if you are sitting in the airport and see

someone trip and fall over their own two feet, you might think “What a idiot” meaning the person’s disposition lead him to trip

However, if you think “He must be late for a flight,” you are making an external attribution

Attributions for the Behavior of Others

Fundamental Attribution Error

Fundamental Attribution Error

Self-FulfillingProphecy

Self-FulfillingProphecy

Attributions for the Behavior of Others

The fundamental attribution error is the tendency as an observer to overestimate internal dispositional influences and underestimate external situational influences upon others’ behavior More simply, we tend to ignore external factors

when explaining the behaviors of other people May have played a role in Milgram’s results: The

teachers figured that if the learner was stupid, he deserved the shocks

Attributions for the Behavior of Others

Placing such blame on victims involves the just-world hypothesis, the assumption that the world is just and that people get what they deserve Helps justify cruelty to others

The primacy effect is partially responsible for the fundamental attribution error In the primacy effect, early information is weighted more

heavily than later information in forming an impression of another person

Be careful of the initial impression you make on others!

Attributions for the Behavior of Others

In the self-fulfilling prophecy, our expectations of a person elicit behavior from the person that confirms our expectations For instance, if you think a person is

uncooperative, you may act in an uncooperative way in your interactions with the person

Given your uncooperative behavior, the person responds by being uncooperative, confirming your expectations

Attributions for Our Own Behavior

Actor-Observer Bias Actor-Observer Bias

Self-Serving Bias Self-Serving Bias

Actor-Observer Bias

The tendency to attribute our own behavior to situational influences, but to attribute the behavior of others to dispositional influences As actors, our attention is focused on the

situation But as observers, our attention is focused on the

individual, hence why we make the fundamental attribution error

Self-Serving Bias

The tendency to make attributions so that one can perceive oneself favorably

As actors, we tend to overestimate dispositional influences when the outcome of our behavior is positive and to overestimate situational influences when the outcome of our behavior is negative

In short, we take credit for our successes but not for our failures

Self-Serving Bias

We tend to see ourselves as “above average” when we compare ourselves to others on positive dimensions such as intelligence and attractiveness However, such traits tend to be normally

distributed with half of us below average and half of us above average

Self-Serving Bias

Self-serving bias can also influence our estimates of the extent to which other people think and act as we do

FalseConsensus

False Uniqueness

Effect

False Consensus Effect

The tendency to overestimate the commonality of one’s opinions and unsuccessful behaviors For instance, if you like a certain type of food, you

overestimate how many people also like that type of food

Or, if you failed an important exam, you tend to overestimate the number of your classmates who also failed the exam

False Uniqueness Effect

The tendency to underestimate the commonality of one’s abilities and successful behaviors For instance, if you are a good golfer, you think

that few people are, thus allowing you to feel good about yourself

When Our Behavior Contradicts Our Attitudes

Attitudes are evaluative reactions (positive or negative) toward things, events, and other people

Our attitudes tend to guide our behavior when the attitudes are ones that we feel strongly about, when we are consciously aware of our attitudes, and when outside influences on our behavior are not strong

When Our Behavior Contradicts Our Attitudes

Impact of Role Playing

Impact of Role Playing

Festinger and Carlsmith’s Study

In the study, participants completed an incredibly boring task, such as turning pegs on a pegboard or organizing spools in a box, dumping them out, and organizing them again

After the hour is over, the experimenter explains to you that the experiment is concerned with the effects of a person’s expectations on their task performance and that you were in the control group

The experimenter is upset because his student assistant has not shown up for the next experimental session

She was supposed to pose as a student who just participated in the experiment and tell the next participant who is waiting outside that this experiment was really enjoyable

Festinger and Carlsmith’s Study

The experiment asks the participant to play the role of the student assistant, and he will pay you either $1 or $20 for telling the next participant (actually a confederate of the experimenter) how enjoyable and interesting the experiment was

After telling the supposed participant how great the experiment was, another person who is studying students’ reaction to experiments asks you to complete a questionnaire about how much you enjoyed the earlier experimental tasks

Festinger and Carlsmith’s Study

Participants who were paid only $1 rated the boring tasks as fairly enjoyable, whereas participants who were paid $20 rated the boring tasks as boring

Possible explanations of this counterintuitive finding…

Festinger’s Cognitive Dissonance Theory

Proposes that people change their attitudes to reduce the cognitive discomfort created by inconsistencies between their attitudes and their behavior For instance, people who smoke, an unhealthy behavior

known to most everyone, may feel cognitive discomfort because of the inconsistency between their behavior and their attitude/knowledge that smoking is bad for their health

According to cognitive dissonance theory, many smokers change their attitude, so that it is no longer inconsistent with their behavior

Festinger’s Cognitive Dissonance Theory

So why did participants paid only $1 indicate on the survey they enjoyed the experiment more than participants paid $20? The people paid $1 lied and said the task was interesting to

another person

Thus, there was an inconsistency between their actions (saying the experiment was interesting without any significant external incentive) and their attitudes (the experiment was in reality quite boring)

To reduce this inconsistency, these participants changed their attitude to be that the tasks were fairly enjoyable

Now the inconsistency and resulting dissonance are gone

Festinger’s Cognitive Dissonance Theory

A key aspect of cognitive dissonance is that we don’t suffer dissonance if we have sufficient justification for our behavior (i.e., the participants paid $20 in the study had perfectly good reason to be inconsistent but not experience dissonance) or our behavior was coerced

Cognitive dissonance theory also says that once you make a tough choice, you will strengthen your commitment to that choice in order to reduce cognitive dissonance

Bem’s Self-Perception Theory

Proposes that when we are unsure of our attitudes we infer them by examining our behavior and the context in which it occurs We have no dissonance to reduce, but are merely

engaging in the normal attribution process For instance, in the experiment, people would examine

their behavior (e.g., lying for $1) and infer the task must have been fairly interesting or else they would not have lied for only that $1

Self-perception theory contends that we don’t change our attitude because of our behavior, but rather we use our behavior to infer our attitude

Cognitive Dissonance vs. Self-Perception

Cognitive dissonance theory is a better explanation for behavior that contradicts well-established attitudes Such behavior creates mental discomfort, and

we change our attitudes to reduce it Self-perception theory explains situations

in which our attitudes are not well-defined We infer our attitudes from our behavior

The Impact of Role-Playing

A role is a social position that carries with it expected behaviors from the person in it

Each role is defined by the socially expected pattern of behavior for it, and these definitions impact both our behavior and our attitudes

Zimbardo’s Study

In a now-classic study, Zimbardo (1970) recruited male college students to participate in a study held in the renovated basement of the Stanford University psychology building, renovated to be a mock prison He chose the most emotionally-stable

volunteers for the study and then randomly assigned them to play the roles of prisoner and prison guard

The guards were given uniforms and billy clubs The prisoners were locked in cells and had to wear

humiliating clothing (smocks with no undergarments)

Zimbardo’s Study

The participants began to take their respective roles too seriously After only one day of “role playing,” the guards started treating the

prisoners cruelly

Some of the prisoners rebelled, and others began to break down

Role-playing quickly became reality The situation deteriorated so much

that Zimbardo had to stop the study after only 6 days

Even these emotionally stable, normal young educated men were vulnerable to the power of the situational roles
