Sample

A

Children from a university nursery school in Stanford, California.

Opportunity sample.

36 boys and 36 girls. Aged between 37 and 69 months (3 -5 years).

Mean age was 52 months (4 1/2 years).

Aggressiveness (potential extraneous variable) was controlled by ensuring each group contained equally aggressive children.

Aggressiveness ratings were determined beforehand by an experimenter who knew the children well and one of the children’s teachers.

There were 2 adult models, a male and a female plus a female experimenter.

Each child only participated in one condition: aggressive model or non-aggressive model or control condition).

In 3 groups: (IV)
Aggressive model
Non aggressive model
Control - no model

Children taken to third room where observed playing with toys and bobo doll

Q

Conclusion(s)

A

1) Shows that people will produce new behaviours that they have observed (i.e., aggression towards a Bobo doll or not showing aggression towards a Bobo doll) and generalise these behaviours to others situations.

2) Also shows that males are more likely to be modelled, possibly because of their higher status.
