Bandura, Ross & Ross Flashcards
Hypotheses (4)
Subjects exposed to aggressive models would reproduce aggressive acts
Observation of non-aggressive model would inhibit aggressive behaviour
Subjects will imitate models of the same sex than those of opposite sex
Boys would display more aggression than girls
Aim
To demonstrate that if children were passive witnesses to an aggressive model they would imitate this aggressive behaviour when given the opportunity
Sample
72 children
Split into: aggressive, non aggressive, control (24)
Split into: male model, female model (12)
Split into: boys and girls (6)
Location?
Stamford university (nursery)
Design
Matched groups - observed in nursery beforehand and rated on physical and verbal aggression

All hypotheses correct
Conclusions
Same as hypothesis
Boys and girls imitated male role model more than female on the whole
Reliability (4)
Model stayed the same
Rehearsed actors
Same experimenter took children round
Toys arranged in same way
Validity
Matched groups used
Children have similar characteristics spread across all groups
Observation
Specific examples of behaviour
2 observers (89% similar) inter eater reliability
Both quantitative and qualitative data recorded
Ethnocentric biased high or low?
Low - only Americans and children of university staff
