Aim
do children who witness aggression later imitate that aggression?

New cards
hypothesis
* subjects exposed to an aggressive model will re produce aggressive acts
* subjects exposed to non aggressive acts will not be aggressive
* subjects will imitate same sex models to a greater degree
* boys will be more aggressive than girls
* subjects exposed to non aggressive acts will not be aggressive
* subjects will imitate same sex models to a greater degree
* boys will be more aggressive than girls

variables
* IV- type of role model like aggressive or non aggressive, male or female role model and children
* DV- children behaviour
* DV- children behaviour

* physical aggression 0-5
* verbal aggression 0-5
* aggression to objects 0-5

Procedure (stage 1)
Exposure to role models
non aggressive group
* child sat at table with arts and crafts
* experimenter comes in with RM
* RM sits quietly
aggressive group
* everything the same but the RM performs a series of violent actions eg, throw bobo doll around, punches and hits the doll, makes aggressive comments
non aggressive group
* child sat at table with arts and crafts
* experimenter comes in with RM
* RM sits quietly
aggressive group
* everything the same but the RM performs a series of violent actions eg, throw bobo doll around, punches and hits the doll, makes aggressive comments

Procedure (stage 2)
Aggression arousal
* experimenter takes child into a toy filled room
* child stays in room until they are focused on one toy experimenter says “NO THESE TOYS R FOR GOOD CHILDREN NOT FOR U”
* experimenter takes child into a toy filled room
* child stays in room until they are focused on one toy experimenter says “NO THESE TOYS R FOR GOOD CHILDREN NOT FOR U”

Procedure (stage 3)
Test of Imitation
* children in room with one way mirror so experimenter can observe from the other side
* there is a peg board and mallet a tetherball arts and crafts, toys, a gun and the bobo doll
* children stay in room for 20 minutes while the researcher records what they do from the other side of the glass using a behavioural checklist

results
* subjects with aggressive role models more likely to imitate aggressive behaviour eg, mallet aggression in FC shown the MRM was 18.8 whereas FC shown non aggressive MRM was 0.5.
* showing SLT

Determinism/ freewill
DETERMINISM
* RM is determining the behaviour of the child
* RM is determining the behaviour of the child
22
New cards
Reductionism/ holism
Reductionist
* as stimulus causes a response, the behaviour of role model caused the child to be aggressive.
