Basic Motives Underlying Prosocial
Behavior
A basic question that people have
asked is whether people are willing to
help when there is nothing to gain, or if
they only help when there is somebenefit for them.

Basic Motives Underlying Prosocial
Behavior
Evolutionary Psychology: Instincts andGenes
Evolutionary Psychologyis the attempt to
explain social behavior in terms of genetic
factors that evolved over time, according tothe principles of natural selection.

Basic Motives Underlying Prosocial
Behavior
Evolutionary Psychology: Instincts andGenes
Darwin recognized that altruistic behavior
posed a problem for his theory: if an
organism acts altruistically, it maydecrease its own reproductive fitness.

Basic Motives Underlying Prosocial
Behavior
Evolutionary Psychology: Instincts andGenes
The idea of kin select ionis the idea that
behaviors that help a genetic relative are
favored by natural selection.[Suggests can pass on genes by helping
genetic relatives have children or by
helping their children survive.]

Basic Motives Underlying Prosocial
Behavior

The norm of rec iproc i tyis the expectation
that helping others will increase the
likelihood that they will help us in thefuture.
[Suggests reciprocity may increase likelihood of
survival.]

Evaluation of Evolutionaryapproach
Although theorists can tell a story aboutevolutionary reasons for helping, wecannot know for sure whether helping has
an evolutionary basis.
Retrospective explanations, no hardevidence.

Basic Motives Underlying Prosocial
Behavior
Social Exchange: The Costs andRewards of Helping
Social exchange theory argues that much of
what we do stems from the desire to
maximize our outcomes and minimize our
costs. Like evolutionary psychology, it is a
theory based on self-interest; unlike it, it
does not assume that self-interest has a
genetic basis.

Basic Motives Underlying Prosocial
Behavior
Social Exchange: The Costs andRewards of Helping
Helping can be rewarding because
increases the probability that someone
will help us in return
relieves the personal distress of the
bystander
gains us social approval and increased
self-worth.

Social Exchange: The Costs andRewards of Helping
Helping can also be costly (danger, time,
money); thus it decreases when costs are
high.

Basic Motives Underlying Prosocial
Behavior
Empathy and Altruism: The Pure Motivefor Helping
Batson (1991) is the strongest proponent of
the idea that people often help purely out of
the goodness of their hearts.

Empathy and Altruism: The Pure Motivefor Helping
He argues that pure altruism is most likely
to come into play when we experience
empathyfor the person in need; that is, we
are able to experience events and emotionsthe way that person experiences them.

Altruistic or egoistic motives?
It is often difficult to disentangle whetherpeople are helping for altruistic or egoisticmotives.
If someone feels joy after helping, is that anegoistic motive?

Personal Determinants of ProsocialBehavior
Individual Differences: The AltruisticPersonality
Research has found that the extent to
which people are helpful in one situation isNOT highly related to how prosocial they
are in another situation.
*High altruism scores not a good predictor
of helping
Personality is not the only determinant of
whether people will help, at least across
many situations.

Gender and Helping
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 ofanother). Why?
--Women are more likely to help those theyalready know.
--Men are more likely to help strangers inemergency situations.

Gender Differences in Prosocial Behavior
Ex: Men > likely to help w/flat tire or in
dangerous situation. (short-term, strangers)
Women > likely to help take care of a
neighbor or elderly relative. (longer-term, closerelationships)

Gender differences in receiving help
Are people more likely to help women or
men? It depends.
Male helpers are more likely to help women thanmen.
Female helpers are equally likely to help men and
women.
Women not only receive more help frommen, but they also SEEK more help.

Personal Determinants of ProsocialBehavior
Cultural Differences in ProsocialBehavior
People across cultures are more likely to
help members of their in -group, the group
with which an individual identifies as a
member, than members of the out-group, agroup with which an individual does not
identity.

Cultural Differences in ProsocialBehavior
People from collectivist cultures are more
prone to help in-group members and less
likely to help out-group members than are
people from individualist cultures.

The Effects of Mood on ProsocialBehavior
People who are in a good mood are more
likely to help.
8/13/2019 Outline f05 N.helping (1)
35/65
Personal Determinants of ProsocialBehavior
The Effects of Mood on Prosocial Behavior
Good moods can increase helping for
three reasons
good moods make us interpret events in asympathetic way
helping another prolongs the good moodgood moods increase self-attention and this in
turn leads us to be more likely to behave
according to our values and beliefs (and most
of us value altruism).

36/65
Positive Mood: Feel good, do good
When researchers have induced a goodmood (e.g., leaving dimes in the coinreturn slot of a pay phone, giving people
cookies, etc.), they find that people in agood mood are more likely to help thanthose in a neutral mood.

people help in order to alleviate their own
sadness and distress; it exemplifies asocial exchange approach.

Negative mood and helping
Variety of studies show that, when peoplefeel sad, they are more likely to help (e.g.,donate money to a charity).
8/13/2019 Outline f05 N.helping (1)
39/65
Helping can be increased by events that
trigger temporary sadness:
Reminiscing about unhappy experiences
Reading depressing statements
Failing at a task
Witnessing harm to another
Presence of Sadness

How can a sad mood and a happy mood both leadto more helping?
Different reasons
Sadness: Helping may improve temporarysadness. (But, if we blame others for ourbad mood, sadness is not associated withmore helping.) Complex association.
Happiness: May trigger positive thoughts
about others. May prolong good mood.Straightforward, consistent association.

Situational Determinants ofProsocial Behavior
Environments: Rural versus Urban
People in rural areas are more helpful. This
effect holds over a wide variety of helping
situations and in many countries.
8/13/2019 Outline f05 N.helping (1)

Situational Determinants ofProsocial Behavior
Environments: Rural versus Urban
One explanation is that people from rural
settings are brought up to be more
neighborly and more likely to trust
strangers.

Situational determinants ofprosocial behavior
Or, it might be that people living in cities
are overwhelmed with too much
stimulation; if you put them in a calmer
environment, they might be just aslikely to help.

Situational Determinants of Prosocial
Behavior
Field studies conducted in 36 cities in theU.S.
The more densely populated the area, theless likely people were to help.
Location (rural or urban) more importantthan whether person grew up in small
town or large city.

The Number of Bystanders: TheBystander Effect
The bystander effectis the finding that the
greater the number of bystanders who
witness an emergency, the less likely any
one of them is to help.

Situational Determinants ofProsocial Behavior
The Number of Bystanders: TheBystander Effect
Latan and Darley (1970) developed a decision treeto show how people decide whether to help in an
emergency:
1. Noticing an Event: Yes No
2. Interpreting the Event as an Emergency Yes No3. Assuming Responsibility Yes No
4. Knowing How to Help Yes No
5. Deciding to Implement the Help Yes No

The Number of Bystanders: TheBystander Effect
Plural is t ic ignoranceis the phenomenon
whereby bystanders assume that nothing iswrong in an emergency because no one else
looks concerned. This greatly interferes with
the interpretation of the event as an
emergency and therefore reduces helping.

phenomenon whereby each bystanderssense of responsibility to help decreases as

The Nature of the Relationship:Communal Versus Exchange
Relationships
Communal relationships are those in which
peoples primary concern is with the welfare
of the other, whereas exchangerelationships are governed by equity
concerns.

The Nature of the Relationship:Communal Versus Exchange
Relationships
Communal/exchange distinction means that
generally we are more helpful towards
friends (> likely to be communal) thanstrangers; the exception occurs when the
other is beating us in a domain that is
personally important and thus threatens our
self-esteem. (Recall Tesser video)
