Types of Prosocial Behavior
• Prosocial behavior (broadest term)
– Action intended to benefit another
– Can be done to gain either external or internal reward
• Benevolence (slightly narrower term)
– Action intended to benefit another, but not to gain external
reward)
• Pure altruism
– Action intended to solely benefit another
– No external reward to the helper
– No internal reward to the helper
• Some argue there is no such thing as pure altruism

Helping requires investment of time, energy,
attention, funds…so why do we do it?
• Goals of Prosocial Behavior
– Gaining Genetic and Material Benefits
• Inclusive Fitness
• Reciprocal Aid
– Gaining Social Status and Approval
– Managing Self-Image
– Managing Our Moods and Emotions
Evolutionary Factors in Helping:
The “Selfish Gene”
• What is important is survival of the individual’s
genes, not survival of the fittest individual
• Kinship selection is the tendency to help genetic
relatives
– Strongest when biological stakes are particularly high
Insights into the Evolution of Help
• Inclusive Fitness – The ability of one’s genes to survive in one’s
own offspring AND in any relatives one
helps
– Helping a close relative promotes the
survival of those genes

Burnstein, Crandall, & Kitayama (1994)
• There are three people who need you to run a small
errand to the store:
– A cousin
– A sister
– An acquaintance
• You have time to help only one…
– Whose errand do you run?
I made this one up…
• If your house is burning down and there are several
people asleep
• You only have time to save one person – who of the
following would you save?
– Your Uncle Charlie who owes you $200
– Your step-mother who has raised you since you were two
and you love very much
– Your adopted son who you have raised since he was 6
months old and you love very much
– Your biological son who you haven’t spoken to since you
kicked out of the house for smoking pot
Who do you help?
• Burnstein, Crandall, & Kitayama (1994)
– Participants in this study were asked to imagine
scenarios like the following:
• There are three people asleep in different rooms
of a burning house:
– Your 7 year-old female cousin
– Your 75 year-old grandfather
– A 21 year-old acquaintance
• You have time to rescue only one…
– Who do you save?

Burnstein, Crandall, & Kitayama (1994):
Findings
• Kin are helped more than non-kin, especially in life-ordeath situations
• Females are helped more than males, except elderly
females (post- menopausal)
• Young are helped more than old
• Healthy relatives helped more than non-healthy in lifeor-death situations
• In life-or-death helping, relatedness matters (this
assures that our genes will continue)
• In everyday helping, we may be guided more by social
norms and moral rules (e.g., "help the sick")
•
Scratch my back and I’ll scratch yours…
• Reciprocal Aid
– Trivers (1971)
• The theory of reciprocal altruism predicts that
altruistic behaviors will also be a function of
beliefs about the recipient's likelihood of
reciprocating…
• Help that occurs in return for prior help
• Animals will help non-relatives if they live in
close proximity and can better survive by
sharing
Evolutionary Factors in Helping:
The Cooperative Group
• Humans can sometimes increase their
reproductive success in two ways:
– By protecting their own self-interest in relation to
other individuals
– By protecting their group’s interests in relation to
other groups
• Helping based on social connections rather than
genetic relationships
Rewards of Helping:
Helping Others to Help Oneself
• More likely to help when the potential rewards
of helping seem high relative to the potential
costs.
• Arousal: Cost-Reward Model
– What are the costs and rewards associated with
helping?
Rewards of Helping: Helping
to Feel Good
• More likely to help:
– If self-esteem has been threatened by failure
– Feeling guilty about something
• Relationship between helping and feeling better.
• Helping others to feel good is often not a
conscious decision, but it can be
Rewards of Helping: Helping to
Be or Appear Good
• Social Responsibility Norm
– Societal rule that people should help those who
need their assistance
– May help because motivated to behave in ways that
are consistent with moral principles.
– Sometimes help for the appearance of morality but
really have selfish motives.
• Moral hypocrisy
• Overhelping
Costs of Helping or of Not
Helping
• Helping has its costs as well as its rewards.
• Helping can also be more sustained and deliberate.
– Courageous resistance
• Helping can have negative health effects if involves
constant and exhausting demands.
Altruism or Egoism:
The Great Debate
• Is helping motivated by altruistic or egoistic
concerns?
– Altruistic: Motivated by the desire to increase
another’s welfare
– Egoistic: Motivated by the desire to increase one’s
own welfare
• Batson: The motivation behind some helpful
actions is truly altruistic

Telling the Difference Between
Egoistic and Altruistic Motives
• How easy it to escape from a helping situation?
– If egoistic motive, helping should decline when
escape from the situation is easy
– If altruistic motive, help is given regardless of ease
of escape
Batson et al. (1981)
• Students in one experiment were given
the opportunity to help a suffering student
(Elaine) by taking her place in an electric
shock experiment
– Half could easily escape the whole situation
by leaving immediately
– The other half would have to stay and watch
as she received the remaining shocks
Batson et al. (1981)
• Students given the easy
opportunity to escape
usually took it…
• But if they felt high
empathy for Elaine they
were more likely to help her
out
• Dan Batson and colleagues
argue that empathy engages
pure altruism, and overrides
selfish motivations
Egoistic Alternatives
• Empathy encourages helping because of
concern about the costs to the self of not
helping
• Empathy highlights the potential rewards for
helping others
– Negative state relief model
• Helper experiences empathic joy by helping
another person
Altruism vs. Egoism:
Limits and Convergence
• Strong evidence for the empathy-altruism
hypothesis
• Limitations to empathy-altruism hypothesis:
– Not all helping is altruistically motivated
– Motives do not guarantee behavior
– Is the assumption that there is a clear divide between
the self and the other a valid one?
An egoistic alternative?
• Cialdini and his colleagues argue that there is
an egoistic explanation of these findings:
– Empathy causes an observer to feel kinship with
the victim, thus tapping into a basic selfish
motivation – to serve myself by serving those who
share my genes
“I didn’t want to get involved…”
• Kitty Genovese Tragedy
(March 13, 1964)
– We watched video clips on
this last week…
– Kew Gardens apartment in
Queens, NYC where Kitty
lived 
Winston Moseley , mugshot
She might still be alive today…
Bystander Effect
• The tragic story of Kitty Genovese.
– Why did no one help?
– Latané & Darley:
• Were social psychological processes at work?
Diffusion of Responsibility
• “Bystander Effect”
– Tendency for each group member to dilute
personal responsibility for acting by spreading it
among all other group members
Taking Responsibility
• Moriarty (1975)
– Jones Beach study - confederate steals a radio
• DV: % who intervene to stop theft
• IV1: question asked
– “Would you watch my things?” or “ Do you have a light?”
• IV2: sex
– Results:
• A percentage of subjects who intervened to stop a thief at Jones
Beach, New York, varied according to whether the subjects felt they
had a responsibility to stop the thief
• Asking subjects to ''watch my things" proved very effective, although
certainly not by reducing fear of the thief
Latané & Darley (1970)
• Helping is the last step of a process involving multiple
decisions:
– Helping Decision Tree
• 1. Notice the incident
• 2. Interpret incident as emergency
• 3. Assume responsibility
• 4. Know the appropriate response
• 5. Implement decision to help

From P.M. Markey, Computers in Human Behavior, 16 (2002) 183-188.
Time Costs…
• Darley and Batson (1973)
– 40 students from Princeton Theological Seminary
• Researchers asked half of the subjects to prepare
themselves for a brief talk on the parable of the
Good Samaritan and half were told that they
would be asked questions concerning
employment prospects for seminary students
IV’s
• Some subjects were put in the “early” condition…
– “It will be a few minutes before they are ready for
you but why don’t you head over there anyway…”
• Some subjects were put in the “on time”
condition…
– “They’re just about ready for you…if you leave now
you’ll be right on time”
• Some subjects were put in the “late” condition…
– “They were expecting you a few minutes ago, better
hurry…”
Personality Measure was also included…
• Before all this was done, subjects were given a
questionnaire intended to measure their basis for
interest in religion…
• They were asked: Did their religious interest
primarily have to do with:
– assuring their personal salvation
or
– their concern for helping others
Is there time enough to be a Good Samaritan?
• On their way to the next building they passed a
poorly dressed man slumped in a doorway, head
down, eyes closed, not moving…
• As the subject moved past him, the man
coughed twice and began groaning
Pitting Dispositions Against Situations
• Darley and Batson (1973) compared the strength
of a seemingly important dispositional factor
(primarily altruistic or not) with a relatively small
situational variable (early or late)…

Pluralistic Ignorance
• Phenomenon that occurs when bystanders to
an emergency, trying to look poised, give
misleading cues to others that no help is
needed
Bystanders as sources of
information about helping
• Results suggest that people look to others to
provide information…
– If no one else seems upset, that suggests this isn’t
an emergency
Latane & Darley (1968):
Smoke study
• In this study, researchers pumped smoke into a
lab while students filled out a questionnaire…
– Some students were left alone
– Some with 2 other real participants
– Some with 2 other confederates who
pretended nothing was wrong

• Being around others made people less likely to

Location and Culture
• Do individuals have a worse chance of being
helped in an emergency in a big city than in a
small town?
• Greater population density is associated with
less helping.
Evans & Lepore, 1993
Milgram, 1970
• Helping is less likely in densely packed
cities…
• Part of the problem is that people living in
dense urban environments pay less attention to
those around them

Managing Our Moods and Emotions
Dovidio, Piliavin, Gaertner, Schroeder, & Clark (1991)
• Arousal/Cost-reward model
– View that observers of suffering help to relieve
their own personal distress
– We will help in emergency if:
• We feel negative arousal, and other conditions
suggest that helping will alleviate the unpleasant
feeling
Cialdini et al. (1982)
Schaller & Cialdini (1990)
• Mood management hypothesis
– Idea that people use helping tactically to
manage their moods
– Throughout life, we learn that helping others
can lead to rewards
– This reward makes us feel good, and we
learn to use helping to manage our mood

Good Moods Lead to Helping:
Reasons
• Why feeling good leads to doing good:
–
–
–
–
Desire to maintain one’s good mood
Positive expectations about helping
Positive thoughts
Positive thoughts and expectations about social
activities
Good Moods Lead to Helping:
Limitations
• Why feeling good might not lead to doing good:
– Costs of helping are high
– Positive thoughts about other social activities that
conflict with helping
Bad Moods and Helping
• When negative moods make us more likely to
help others:
– If we take responsibility for what caused our bad
mood (i.e., feel guilty)
– If we focus on other people
– If we are made to think about our personal values
that promote helping

Best to wait until after confession…
• Harris, Benson, & Hall (1975)
– Higher percentage of Catholic subjects donated
money to a charity after confession
– Guilt seems to lead to altruism
Bad Moods and Helping
• When negative moods make us less likely to help
others:
– If we blame others for our bad mood
– If we become very self-focused
– If we are made to think about our personal values
that do not promote helping
Effects of Those Around Us
• Observing another giving help can teach young
children about the helping norm
• For adults, a model can remind them of the
helping norm
Awareness of the Helping Norm
• Froming, Allen, & Jensen (1985)
– Very young children are not aware of the norm
requiring people to help those in need
– Between 6 and 9 years of age, they become aware
of the norm
– At this age, they will help if an adult is present
Essential Qualities for an
Altruistic Personality
• Empathy
• Internalized and advanced moral reasoning
• Attractiveness
– Physical Appearance
• I think we’ve talked enough about that effect
already
– Charisma
• Penner and Fritzsche (1993)
– Example: Earvin Johnson
Magic’s Influence on Helping Others
Penner & Fritzsche, 1993.
Attributions of Responsibility
• Beliefs about the needy person’s responsibility
influences helping
• Effect particularly strong among those who
believe in a just world
Does it matter if he’s drunk?
• Piliavin (1981): The New York Subway
Experiment
– Teams of 4 traveling on NY subways (Victim/model/2
observers)
– Recorded number of people in car, gender, race, etc.
– Victim: always male, either white or AfricanAmerican/sometimes with a cane, sometimes drunk
– Victim collapses/model instructed to help after exactly
70 seconds
• Results???
Similarity and Familiarity
• Dovidio (1984)
– In 34 studies, 29 found significantly higher
helping for similar over dissimilar others
• Gaertner & Dovidio (1986)
– However, people will often help people of
other races but only if not helping might
make them appear prejudiced
Similarity and Familiarity
• Familiarity may also be a cue to genetic relatedness
– Our ancestors encountered their relatives on a
daily basis
– In animal and human societies, familiarity
increases helping
• Schroeder, Penner, Dovidio, & Piliavin, 1995
– If familiarity is associated with shared genes,
helping familiar others would have generally
helped relatives
Gender and Helping
• Classic male-helper scenario:
“Knight in shining armor”
• Classic female-helper scenario:
“Social support”
• Gender differences in willingness to seek help
Gender and Help
• Williams & Best (1990)
– Women are universally perceived as kinder, more
soft-hearted, and more helpful
– But over 90% of Carnegie Hero awards go to men
(for saving, or attempting to save, the life of
another)
• Why?
Threat-to-Self-Esteem Model
• Help is experienced as self-supportive when
recipient feels appreciated and cared for
• Help is experienced as self-threatening when
recipient feels inferior and overly dependent
When Is Receiving Help
Perceived as Threatening?
• Those with high self-esteem tend to react more
negatively than those with low self-esteem
• Being helped by a similar other may imply that
recipient is inferior
• Help from a significant other on an ego-relevant
task can threaten one’s self-esteem
Shotland & Straw (1976)
• Sometimes people assume help would be seen
as an unwelcome intrusion…
– When a woman fighting with a man shouted: “I
don’t even know you!” - help was more likely than
if she shouted: “I don’t know why I married you!”
