Bandura sample
36 boys and 36 girls from Stanford University Nursey.
opportunity sample- who was available at the time
Mean age of 52 months
Inter-rater observation of aggression using a 4 five point scale.
Bandura research method
Lab experiment
Bandura design
Matched pairs design
Bandura apparatus
various toys including a bobo doll
Bandura procedure
Phase 1- Modelling, 1 group with aggressive model hitting and throwing bobo doll, another with non aggressive model playing with tinker toys and another with no model
Phase 2- Aggression arousal, play was stopped with cars but them toys were for special children only
Phase 3-Tested for delayed imitation children were observed every 5 seconds through a one way mirror, there was violent toys and non violent toys
Bandura results
Children in aggressive group imitated many models physical and verbal behaviours aggressive and non aggressive
Children in other conditions showed few aggressive behaviours
Agressive group displayed more non imitative agression than non agressive group
Same sex imitation effect present for boys
Male models had greater influence than female models
Boys imitated more physical agression then girls
