Helping Theories
 Helping behavior: act intended to benefit
another
 Altruism: unselfish concern for another’s
welfare
Helping Theories
 Arousal Theory: sight of victim produces anxiety
so you act
 Cost-Reward Theory:


Cost of helping low & cost of not helping high - help
Cost of helping high & cost of not helping low - no
 Empathy-Altruism Theory: feeling empathy for
other increases chances of helping
 Evolutionary Theory: contributed to our survival in
the past
Kitty Genovese
 Bystander effect: as number of
bystanders increases, the
likelihood of any one by-stander
helping decreases
 Diffusion of responsibility: Dilution
or weakening of each group
member’s obligation to act when
responsibility is perceived to be
shared with all group members
Bystander Intervention Problem: Latane and Darley;
Best predictor of bystander intervention was group size

judgments
 Asch identifies three factors that influence whether a
person will yield to pressure:



The size of the majority
The presence of a partner who dissented from the majority
The size of the discrepancy between the correct answer and
the majority position
Cognitive Dissonance
 A highly motivating state in which people
have conflicting cognitions, especially when
their voluntary actions conflict with their
attitudes – Leon Festinger
 Must change either behavior or thoughts
Inducing Compliance
 Foot-in-the-door technique: get one to agree
to small request and then gradually present
larger ones

Drive Carefully sign & charities
 Door-in-the-face technique: ask for large
favor likely to be denied and then ask for
something less

others can improve performance

group task than when performing the same task alone
 Deindividuation: When group members lose individuality
and tend to do things not normally done when alone
 lose sense of personal responsibility
 group “assumes” responsibility
 Group polarization: tendency of people to make decisions
that are more extreme when they are in a group as opposed
to a decision made alone or independently.

potential value of the relationship against their
expectations of success in establishing the
