What were the results of Bandura et al's study? Provide 2 evaluation points for the study.
The children who observed the aggressive model produced a great deal of aggressive acts towards the Bobo doll (resembling those of the model). Those in the non-aggressive condition did not produce any aggressive acts towards the Bobo doll.
Possible evaluation points:
There was manipulation of an IV to see the impact on a DV. There was random allocation of participants to groups. All other variables were controlled. They tested a hypothesis and used standardized instructions. Thus, it was a true experiment allowing for a cause and effect relationship to be established.
Standardized instructions allow for replication and similar studies have resulted in similar findings, thus it is highly reliable.
Use of children as participants limits the impact of demand characteristics.
Many ethical issues… The is a concern that children were very young and furthermore, that the study may have taught them how to be violent (psychological harm).
Low ecological validity: They didn’t know the model, they didn’t interact with the model, questions about appropriateness of the bobo doll. It was a very limited social setting.
The novel nature of the Bobo doll encourages people to hit it, without having anything to do with aggression. It may have been more like a game. (Lowers internal validity)
A further criticism of the study is that the demonstrations are measured almost immediately. With such snap shot studies, we cannot discover if such a single exposure can have long-term effects.
