4PROSOCIAL BEHAVIOR
- Introduction
- Overview
- Developmental trends
- Factors affecting the development maintenance
of prosocial behavior - The altruistic personality (Shigetomi et al.)
- Hypocritical models (Midlarsky Bryan)
- Gender differences in altruism (Abbott et al.)
- Next Moral Development (22)
5Introduction
- Case of Kitty Genovese
- Problem of definition of altruism Motivational
(intent) versus Behavioral (what did they do?) - Theories See text. Ethological Theory (we are
pre-wired to act altruistically) generated some
attention
6Developmental Trends
- Early examples of sharing and of empathic
responding - Age differences Age positively correlates with
frequency of altruism. Why? Older kids - understand when others are in need
- know how to help
- understanding the norm of
social responsibilityhelp
- those in need
7Factors affecting development
- Factors affecting the development and maintenance
of prosocial behavior - modeling and reinforcement
- practice
- nurturing caregiversthink about this
- role-taking and empathy
- moral reasoning
- use of induction procedure

10Are People Consistent in Their Altruism
- Does the altruistic personality exist?
- Replication of the famous Hartshorne, May,
Mahler study of the 30s by Shigetomi, Hartmann,
Gelfand - Basic question Are individuals consistent across
domains of prosocial behavior? - Studied 279 fifth and sixth grade children in SLC
School District. Altruistic behavior measured
with six classroom tasks which provided
participants with opportunities to help other
children

12Practicing Preaching The Effects of
Hypocritical Models
- Introduction
- During game children observed model
- act generously or selfishly with their winnings
on 5 successful trials and - exhort either generosity ("I know that I don't
have to give, but it would make some children
very happy") or selfishness ("I could really use
some spending money this week it makes some
children feel bad to get charity") - Children then played game and won on 5 trials,
and were given opportunity to share
13So Why Talk Further About It?
- What can we infer from this study?
- Greatest (most extreme) effects occur when
conditions match (gg, rr)? - Action more important than admonition? Careful
now!
- Action Preach Condit.

14Gender Differences in Altruism
- History Tremendous inconsistencies.
- With reputational measures, ? gt ?
- With behavioral measures, sometimes ? gt ?, ? lt ?,
? ? - So what is the trend? Depends on what review you
read!
15The Narrative Review
- Traditional narrative reviewperhaps the fault.
Problems include the following - selection of studies What is included
what is excluded? What search
engines do we use to find relevant
studies? - compare studies that have different methods and
results How do you compare apples oranges?
16Meta Analytic Reviews
- Favored alternative Meta analytic review.
Analogue of primary study that includes the
following - systematic method of study identification
(analogous to systematic method of selecting
subjects in primary study) - method of combining studies
- assessing stability of results (file drawer
issue) - determining moderating variables that are
associated with outcomes (e.g., type of helping
task, such as rescue versus donating) -
17Abbotts Procedures
- Finessed the study selection procedure
by using the same sample of study used
in the most frequently cited
narrative review - Identified each test of gender difference in the
73 studies included in that reviewsome 195
separate tests of gender differences - For each hypothesis, identified an effect size
(ES)which tells the magnitude of the difference
between the sexes - (M? - M?)/SDITS A STANDARD SCORE!
18Abbotts Procedures
- Determined the statistical significance of the
average ES - Determined the number of null
studies in file drawers that would be
required to wipe out significance - Coded for each study a range of study variables,
including the type of prosocial behavior, age of
kids, gender of investigator, SES and residency,
method of measurement, type of study (modeling,
reinforcement).
19Are there Gender Differen-ces in Altruistic
Behavior
?
- Abbotts Results
- Highly significant difference
favoring girls - (90 outcomes favoring girls, 45 favoring boys
the remainder no differences - Average affect size .047 of a standard deviation
(very, very small) - About 2,000 studies no-effect studies would have
to be present in investigators file drawers to
wash out significance (the file drawer number).
20Sometimes even a little gender difference makes a
difference!
