The results for the Bobo Doll Experiment showed, as expected by prediction one, that children who were exposed to the aggressive model were more likely to show imitative aggressive behavior themselves.
Children were chosen as subjects for the study, because they have less social conditioning; they have also had less instruction and teaching of the rules of society than adult subjects.
For the Bobo Doll Experiment, Bandura selected a number of children from the local Stanford Nursery School, varying in age from 3 to 6 years, with the average age being 4 years and 4 months.
The child was not permitted to play with these toys, being told that they were reserved for other children to play with.
This was intended to build up the levels of frustration within the subject.
Television, computer games, food additives, music and the lack of role models are all cited as reasons for a supposed breakdown in society, and an increased tendency towards violence.
These concerns have existed for many years, even before the media turned these factors into sensationalist stories, to try and sell more newspapers.
The child was then taken into yet another room filled with interesting toys, some of an aggressive type, some non-aggressive; the room also contained the Bobo doll and the mallet.
The subject was watched through a one-way mirror, and a number of types of behavior were assessed.
The third group was structured in exactly the same way as the second, the only difference being that they would be exposed to a passive adult.
For the Bobo Doll Experiment, it was necessary to pre-select and sort the children, to try and ensure that there was an even spread of personality types across the test groups; some subjects already known to be more aggressive in personality than others.
