Aims & Hypotheses
- Investigate observational learning of aggression.
- To investigate whetehr children would reproduce aggressive behaviour when the model was no longer present, and to look for gender differences in learning of aggression.
- Participants exposed to an aggressive model would be more likely to reproduce similar aggressive behaviour than those exposed to a non-aggressive model, or no model at all.
- Participants expsed to a non-aggressive model would be less aggressive than than those exposed to no model at all.
- Participants would more likely imitate agressive behaviour shown by a same sex model.
- Boys would be more inclinded t imitate aggression than boys.

Participants & Design
- A total of 72 participants.
- All from Stanford university nursery school.
- Ages ranged from 37 months to 69 months.
- This was a lab experiment, using independent measures design.
- Three IV's were tested: The behaviour of the model. The sex of the model. The sex of the children
- There were 8 conditions and children were all matched based on pre-decided levels of aggression.
- 12 boys and girls saw aggression from a same sex model, 12 boys and girls saw aggression from an opposite sex model.
- 12 boys and girls saw an opposite sex non-aggressive model, 12 boys and girls saw a same sex non-aggressive model.
- A control group of 24 boys and girls did not see a model at all.
2 of 4
- Each child was individually bought into a room for 10 minutes, in the aggressive condition an adult demonstrated aggression towards a bobo doll. in the non-aggressive condition an adult did not interact with the doll and in the control there was no adult in the room.
- In order to annoy the children, they were taken to another room to play with attractive toys, where after 2 mins were told they could no longer play with them.
- Children were then observed playing for 20 minutes in a room that contained a bobo doll and a range of other toys.
- Three types of aggression were recorded: Imitative aggression - agression identical to the model in stage 1. Partial imitative - similar behaveiour to that carried out by the model. Non-Imitative - new aggressive acts not demonstrated by the model.

Results & Conclusions
- Quantitative data was recorded.
- Children who had witnessed an aggressive model were significantly more aggressive themselves.
- Overall, there was very little difference between aggression in the control group and the non-aggressive group.
- Boys were significantly more likely to imitate aggressive models, the difference for girls was much smaller.
- Boys were significantly more physically aggressive than girls. Girls were more verbally aggressive than boys after observing a female model.
- Witnessing aggression in a model can be enough to produce aggression by the observer.
- Children selectively imitate gender-specific behaviour.
