*Motivation: people must be motivated to imitate behavior (e.g. importance of model).
**Procedure: 36 boys and 36 girls (mean age, 4.4) were divided into three groups matched on levels of aggressiveness. One group saw a model behave aggressively towards a bobo doll, one group saw the model assemble toys and the last acted as a control. the groups were further divided into groups so that some saw same-sex models and some saw opposite-sex models.the models either behaved aggressively or nicely. the children were then brought into the lab with toys and were NOT told what to do.
they were observed for 20 min.**Results:children with aggressive models, behaved more aggressively (physically and verbally) towards the bobo doll. children also liked to imitate same-sex models. boys were more aggressive**Evaluation: the lab exp is low in ecological validity. the aggression here is artificial and there may be demand characteristics. the children were very young and it has been criticized for ethical reasons.
Children (3-8 years) were observed before and after introduction to TV through cameras set up on playgrounds of two primary schools on the island. interviews were also conducted with teachers, parents, older children.**Results: No increase in aggressive or antisocial behavior (the same results after 5 years)**Discussion of results:- children did not change behavior after TV was introduced (even though level of violence was the same as UK's)- parents/ teachers said that antisocial behavior was not accepted on the island + high degree of social control in the community. showing that people may learn BUT NOT exhibit aggressive beahvior.-Social/cultural factors also play a role in what behaviors are acceptable, so even though children had learned aggression, they did not show it.
**Evaluation: the study investigated real-life event and is high in ecol validity. It does NOT question SLT, but rather the results of Bandura and Ross (1961), it also confirms the theory that you have to be motivated to imitate behavior.
