Experiment Break down1. Male and female children aged 3-52. Independent measures experiment - Half exposed

to aggressive model half to non aggressive model. 3. Model shows physical and verbal aggression -

beats the doll and shouts POW!4. Children then exposed to the doll and copy what

they have seen. Clear difference between the 2 condition groups.

5. Some verbal copying in aggressive condition. No verbal aggression from children in other condition.

Social learning

• Child must create mental representations of events in their social environment; We make a mental note of how someone behaves that guides our future behaviour.

• Child also needs to decide if the reward will be greater than any punishment for that aggressive behaviour.

A01

Production of behaviour

• If a child is rewarded they will repeat the same aggressive behaviour again. This will maintain their aggressive actions.

• E.g. bullies get what they want if they are aggressive so will continue to do this.

• Children also need to gain confidence in their aggressive behaviour. If they weren’t good at aggression then they may turn to other behaviours instead due to their low sense of self-efficacy.

A01

Demonstrate

• Create a story board of the steps of the Bobo doll studies with notes. Use page 66.

Homework

• Take notes on the Bobo doll experiment using link below and the book.

• Create AO1 question plan.• http://www.simplypsychology.org/bobo-doll.h
