The Bobo Doll Experiment was performed in 1961 by Albert
Bandura, to try and add credence to his belief that all human
behavior was learned, through social imitation and copying, rather
than inherited through genetic factors.famous and influential
experiment known as the Bobo doll experiment, Albert Bandura and
his colleagues demonstrated one way that children learn aggression.
According to Bandura's social learning theory, learning occurs
through observations and interactions with other people.
Essentially, people learn by watching others and then imitating
these actions.
Bandura made several predictions about what would occur:
- He predicted that children who observed an adult acting
aggressively would be likely to act aggressively even when the
adult model was not present.
- The children who observed the non-aggressive adult model would
be less aggressive than the children who observed the aggressive
model; the non-aggressive exposure group would also be less
aggressive than the control group.
- Children would be more likely to imitate models of the same-sex
rather than models of the opposite-sex.
- Boys would behave more aggressively than girls.
Method Used in the Bobo Doll Experiment
The participants for the experiment were 36 boys and 36 girls
enrolled at the Stanford University Nursery School. The children
ranged in age between 3 and almost 6 years, and the average
participant age was 4 years 4 months.
There were a total of eight experimental groups. Out of these
participants, 24 were assigned to a control group that received no
treatment. The rest of the children were then divided into two
groups of 24 participants each. One of the experimental groups was
then exposed to aggressive models, while the other 24 children were
exposed to non-aggressive models.
Finally, these groups were divided again into groups of boys and
girls. Each of these groups was then divided so that half of the
participants were exposed to a same-sex adult model and the other
half were exposed to an opposite-sex adult model.
Results of the Bobo Doll Experiment
The results of the experiment supported three of the four
original predictions.
- Children exposed to the violet model tended to imitate the
exact behavior they had observed when the adult was no longer
present.
- Bandura and his colleagues had also predicted that children in
the non-aggressive group would behave less aggressively than those
in the control group. The results indicated that while children of
both genders in the non-aggressive group did exhibit less
aggression than the control group, boys who had observed an
opposite-sex model behave non-aggressively were more likely than
those in the control group to engage in violence.
- 3There were important gender differences when it came to
whether a same-sex or opposite-sex model was observed. Boys who
observed adult males behaving violently were more influenced than
those who had observed female models behaving aggressively.
Interestingly, the experimenters found in the same-sex aggressive
groups, boys were more likely to imitate physical acts of violence
while girls were more likely to imitate verbal aggression.
- 4.The researchers were also correct in their prediction that
boys would behave more aggressively than girls. Boys engaged in
more than twice as many acts of aggression than the girls.
Criticisms of the Bobo Doll Experiment
As with any experiment, the Bobo doll study is not without
criticisms:
- Because the experiment took place in a lab setting, some
critics suggest that results observed in this type of location may
not be indicative of what takes place in the real world.
- The study might suffer from selection bias. All participants
were drawn from a narrow pool of students who share the same racial
and socioeconomic background. This makes it difficult to generalize
the results to a larger, more diverse population.
- Since data was collected immediately, it is also difficult to
know what the long-term impact might have been.
- Acting violently toward a doll is a lot different than
displaying aggression or violence against another human being in a
real world setting.
- It has also been suggested that children were not actually
motivated to display aggression when they hit the Bobo doll;
instead, they may have simply been trying to please the
adults.
- Some critics argue that the study itself is unethical. By
manipulating the children into behaving aggressively, they argue,
the experimenters were essentially teaching the children to be
aggressive.
