TV and Violence

Eron & Huesmann (1986)

Results:

Violent TV watching at age 8 predicted:

Aggression at age 19

Criminal acts of violence (rape, robberies, assault) at age 30

Controlled for aggression at age 8

Page 5: Prosocial Behaviour

Moderating Factors in TV-Aggression Link

Model Similarity

Punishment versus Reward

Apparent Reality

Cartoons influence aggression less than film

Apparent consequences

Modelling more likely when pain/harm caused by violence is not depicted

Page 6: Prosocial Behaviour

How Does TV Affect Aggression?

Imparts information about how to aggress

Primes anger and aggression

Makes world seem more dangerous, increases fear of victimization (Gerbner et al., 1994)

Heavy viewers tend to overestimate frequency of violent crime, probability of being assaulted

Loosens inhibitions toward violence

Page 7: Prosocial Behaviour

Food For Thought

“An angry person can pull the trigger of his gun if he wants to commit violence, but the trigger can also pull the finger …”

- Leonard Berkowitz

Page 8: Prosocial Behaviour

Co-operative Dilemmas

Situations where the most beneficial action for an individual will be harmful for the collective group

Commonly discussed social dilemmas:

Escalation of Conflict

Tragedy of the Commons

Prisoner’s Dilemma

Page 9: Prosocial Behaviour

Escalation of Conflict

Interpersonal conflict feeds itself and escalates if one side does not begin concession

Page 10: Prosocial Behaviour

Escalation of Conflict in Close Relationships

Stimulus: Partner APartner A comes home and snaps at Partner BPartner B

Partner BPartner B’s Response:

An equally hurtful remark

Partner BPartner B is vindicated, but Partner APartner A feels compelled to respond with an equally vehement remark

Conflict escalatesescalates

A defusing remark

Partner BPartner B takes a hit in pride, but Partner APartner A has no reason to say another hurtful remark

Conflict defusesdefuses

Page 11: Prosocial Behaviour

Escalation of Conflict in International Relations

Stimulus: Country ACountry A accidentally bombs a civilian area of

Country B Country B during a training exercise

Country BCountry B’s Response:

Bomb them back

Country BCountry B is vindicated, but they are now at war with

Country ACountry A

Accept apology

Country BCountry B takes a hit in many ways, but they maintain peaceful relations with Country ACountry A

Page 12: Prosocial Behaviour

Tragedy of the Commons

A co-operative dilemma in which everyone takes from a common pool of goods that will replenish itself if used in moderation but disappear if overused

Page 13: Prosocial Behaviour

Tragedy of the Commons

Why do we take more than our share?

Anchoring and Adjustment Heuristic

Desired share is used as an anchor

Do not sufficiently adjust down

Size of commons is not readily estimable

Page 14: Prosocial Behaviour

Tragedy of the Commons

When do we take our fair share?

Both the size of the commons and the group that is sharing it are easily determined

The size of an equal share is explicitly stated

Page 15: Prosocial Behaviour

The Prisoner’s Dilemma

A situation where two people must make a collectively-dependent decision without knowing the other person’s decision

A special case of John Nash’s Game Theory

The Prisoner’s Dilemma

Strategies that maximize outcomes:

Winner: Simple Tit-for-Tat strategy

Co-operate on first round

Then mirror opponent’s response

Defect as soon as opponent defects

When game is about to end (last trial):

Defect

Page 18: Prosocial Behaviour

Prosocial Behaviour

Action performed with the goal of benefiting another person

Page 19: Prosocial Behaviour

Altruism

Helping done purely out of a desire to help another person

Does not benefit the self

May even involve a cost to the self

Page 20: Prosocial Behaviour

Altruism : Examples

In 1982, Anne Herbert coined the phrase, “Random Acts of Kindness”

Idea is to do random kind acts for others with no intention of being repaid

Paying tolls for others

Shovelling snow for neighbours, anonymously

Page 21: Prosocial Behaviour

Altruistic Personality

Dispositional tendency to help others across a wide variety of situations

Page 22: Prosocial Behaviour

Are Some More Altruistic Than Others?

Hartshorne & May (1929)

Method:

1. Observed prosocial behaviours of 10,850 school children

2. Focus on behaviours across a number of situations

Page 23: Prosocial Behaviour

Are Some More Altruistic Than Others?

Hartshorne & May (1929)

Results:

Most children helped occasionally

Average correlation between helping in two different situations was .23

Page 24: Prosocial Behaviour

Are Some More Altruistic Than Others?

Summary of Hartshorne & May (1929):

Most children help, but it depends on the situation

Also, self-report measures of altruism typically do not predict actual altruistic behaviour

Page 25: Prosocial Behaviour

How Do People Help?

McGuire (1994)

Method:

1. Surveyed 2 sample of college students for types of helping both given and received

First sample received only open-ended questions

Second sample rated the first sample’s responses on frequency, importance, causes, and consequences

2. Factor analysed data

Page 26: Prosocial Behaviour

How Do People Help?

McGuire (1994)

Results: Factor Analysis revealed 4 dimensions of helping

Casual helping

Substantial helping

Emotional helping

Emergency helping

Page 27: Prosocial Behaviour

How Do People Help?

McGuire (1994)

Results: Casual Helping

Helping with a homework assignment or schoolwork

Lending a book, notes, record album, household item

Giving a ride within the city

Giving directions

Opening or holding a door

Giving someone a snack

Page 28: Prosocial Behaviour

How Do People Help?

McGuire (1994)

Results: Substantial Personal Helping

Bringing or sending flowers, a card, or a small gift

Giving a ride a long distance (greater than 20 miles)

Helping someone pack or move

Visiting someone from out of town

Page 29: Prosocial Behaviour

How Do People Help?

McGuire (1994)

Results: Emotional helping

Listening to someone talk through a problem

Giving advice about a situation someone is in

"Being there" for someone; providing loyalty

Page 30: Prosocial Behaviour

How Do People Help?

McGuire (1994)

Results: Emergency helping

Starting a car or changing a tire for someone

Taking care of someone who is sick

Walking someone home at night

Page 31: Prosocial Behaviour

When Do We Help?

The situation can influence whether we will help another person (Altruism) or not (Bystander Apathy)

Page 32: Prosocial Behaviour

When Do We Help?

Situational Factors in Helping:

Mood

Spare time

Environment

Number of Bystanders

Relationship with Person In Need

Page 33: Prosocial Behaviour

Mood

Mood affects helping behaviour

Good news:

Both good and bad moods increase helping relative to neutral mood

Page 34: Prosocial Behaviour

Positive Mood & Helping

Isen & Levin (1972)

Method:

1. Participants were random shoppers at a shopping mall

2. Positive mood induced or not:

Positive mood induction: Left a dime in a pay phone

Control: No dime

3. Observe other person drop papers after leaving phone booth

Page 35: Prosocial Behaviour

Positive Mood & Helping

Isen & Levin (1972)

Results: How many people helped pick up the person’s papers?

Page 36: Prosocial Behaviour

Why Positive Mood?

More likely to make positive attributions for others’ behaviour and give them the benefit of the doubt

Helping helps us maintain good mood

Good moods increase self-attention, so we act more consistently with our values

Page 37: Prosocial Behaviour

Negative Mood & Helping

Negative State Relief

When we feel bad, we are more likely to help

Page 38: Prosocial Behaviour

Spare Time

We help less when we feel rushed for time

Page 39: Prosocial Behaviour

Good Samaritan Study

Darley & Batson (1973)

Method:

1. Ps were Princeton theology students, told it was a study about persuasion

2. Ps first spent 10 minutes preparing a sermon on the Good Samaritan, which they will give to an audience at another building on campus

3. Hurry manipulation: Experimenter says ...

Not in hurry: “You will have enough time to get there”

Moderate hurry: “You will have just enough time to get there”

High hurry/Late: “You will be late”

On the way to talk, pass hurting confederate

Page 40: Prosocial Behaviour

Good Samaritan Study

Darley & Batson (1973)

Results: % of Theology Students Who Stopped to Help

Page 41: Prosocial Behaviour

Environment

Urban versus Rural Environments

Do you think you are more likely to be helped if:

A.You fall down and break a leg in the middle of the Annex

B.You fall down and break a leg in the middle of Grimsby

C.Equally likely to get help in either place

Page 42: Prosocial Behaviour

Urban vs. Rural

Why Would You Get More Help in Rural Environments?

A.Rural values: Rural people are more likely to help

B.Immediate Context: Rural environment facilitates helping

C.A little of both

Page 43: Prosocial Behaviour

Urban Overload Hypothesis

Urban environments constantly bombard you with stimulation, so you keep to yourself to avoid being overwhelmed by it

Evidence:

Where an incident occurs is more important than where the witnesses grew up

City density more important than city size

Page 44: Prosocial Behaviour

Bystander Apathy

March 13, 1964

Kitty Genovese stabbed to death crossing a parking lot while returning from work late at night

Murder took place over 30 minutes

At least 38 independent witnesses

No one called the police for help

Page 45: Prosocial Behaviour

Bystander Apathy Effect

The greater the number of bystanders who witness an emergency, the less likely that any one of them is to help

Page 46: Prosocial Behaviour

Bystander Apathy

Latané & Darley (1970)

Method:

1. Participants discussed “college life” over headphones

2. Group size manipulation:

Lone witness: 1 Participant + 1 Confederate

Two witnesses: 2 Participants + 1 Confederate

Four witnesses: 4 Participants + 1 Confederate

During the discussion, the actor fakes a seizure

Page 47: Prosocial Behaviour

Bystander Apathy

Latané & Darley (1970)

Results: How many people helped?

Page 48: Prosocial Behaviour

Why Does This Happen?

Pluralistic Ignorance

Diffusion of Responsibility

Page 49: Prosocial Behaviour

Pluralistic Ignorance

Bystanders assume that nothing is wrong in an emergency because no one else looks concerned

Page 50: Prosocial Behaviour

QuickTime™ and ampeg4 decompressor

are needed to see this picture.

Smoking Room Study

Page 51: Prosocial Behaviour

Diffusion of Responsibility

Feeling less responsible when others are present, because others are equally able to act

Page 52: Prosocial Behaviour

Bystander Apathy or Sympathy

Sequential Model of Bystander Helping Versus Apathy:

1. Notice the event

2. Interpret the event as an emergency

3. Assume responsibility

4. Know appropriate form of assistance

5. Implement decision

Page 53: Prosocial Behaviour

Breaking the Bystander Apathy Effect

It just takes one person to break pluralistic ignorance and diffusion of responsibility!

It Just Takes One

Page 55: Prosocial Behaviour

Relationship With Person In Need

Kin Selection

Communal Relationships

Ingroups and Outgroups

Page 56: Prosocial Behaviour

Communal Relationships

In communal relationships, we give in response to each other’s needs

Less likely to receive help from relationship partners if in equity relationships

Page 57: Prosocial Behaviour

Ingroups and Outgroups

We are much more likely to help an ingroup member than an outgroup member

Magnification by culture:

Interdependent cultures help ingroup members more than Independent cultures

Interdependent cultures help outgroup members less than Independent cultures

Bystander Apathy & Ingroup Members

Page 59: Prosocial Behaviour

Why Do We Help?

Theories of Helping

Empathy-Altruism Hypothesis

Page 60: Prosocial Behaviour

Why Do People Behave Altruistically?

2 competing hypotheses:

Genuine Altruism

Innate motive to help others in need, without conscious regard for one’s own self-interest

Social exchange theory

All human behaviour, including helping, is geared toward maximizing benefits and minimizing costs to the self

Page 61: Prosocial Behaviour

Why Do People Behave Altruistically?

You Decide: Is there such a thing as genuine altruism?

A.Yes

B.No

C.Undecided

Page 62: Prosocial Behaviour

Reciprocal Altruism

Reciprocal altruism

We are selectively prosocial to those who are prosocial towards us

Page 63: Prosocial Behaviour

Evolutionary Theories

Kin Selection

Behaviours that help a genetic relative are favoured by natural selection

Inclusive Fitness

We select mates not only for who has the most chance to survive, but also for who will maximize our chance of survival

Page 64: Prosocial Behaviour

Helping Others Helps You

Negative State Relief

Seeing others suffer makes us suffer physiologically, so we act pro-social to reduce our own distress

Social rewards

A lot of positive social rewards (e.g., badges, awards, thanks, reputation) for acting in an unselfish manner

Helping increases when followed by social approval, public recognition (Staub, 1978)

Page 65: Prosocial Behaviour

Social Norms

It is socially normative in most cultures to help others

Reciprocity Norm

You should help others that have helped you

Helping Norm

Helpfulness is a socially valuable trait

Page 66: Prosocial Behaviour

Learning Perspective

Prosocial behaviour can be learned like any other behaviour (e.g., via norms, values)

Page 67: Prosocial Behaviour

Reinforcement & Prosocial Behaviour

Prosocial behaviour can be increased by rewarding it

Dispositional praise more effective than behavioural praise

Page 68: Prosocial Behaviour

Social Modelling & Prosocial Behaviour

Seeing others help increases helping

Page 69: Prosocial Behaviour

Social Modelling & Prosocial Behaviour

Sprafkin et al. (1975)

Method:

1. Children watch 1 of 3 TV clips:

Lassie clip where a boy helps a dog

Neutral Lassie clip

Brady Bunch clip

2. Kids were then asked if they would play a game or help puppies in distress

Page 70: Prosocial Behaviour

Social Modelling & Prosocial Behaviour

Sprafkin et al. (1975)

Results:

Helping increased after watching Timmy help Lassie

Page 71: Prosocial Behaviour

Altruism & Empathy

People feel purely altruistic when they are motivated to help by empathy for another

Empathy

The ability to put oneself in the psychological frame of reference of another person

Empathy Altruism Theory

Batson et al. (1991)

Method:

1. Participants observe “Elaine” complete a task and get shocks

2. Empathy manipulation:

High Empathy: Elaine has similar attitudes and background

Low Empathy: Elaine has dissimilar attitudes and background

3. Elaine becomes upset by experimental treatment after 2 shocks, but says she will continue

Participants are asked to take Elaine’s place

Ease of Escape manipulation:

1. Difficult Escape: Participants must stay for remaining 8 trials, regardless of whether they take Elaine’s place, or

Easy Escape: Participants can leave if they don’t want to help Elaine

Page 74: Prosocial Behaviour

Empathy Altruism Theory

Batson et al. (1991)

Results: Participants who took Elaine’s place (helped)
