Bandura, Ross and Ross 1965 Flashcards
what was the hypothesis :
- was predicted that the highest rate of imitation would be given by children if they witnesses a model being rewarded for their behaviour.
- those having no reward or punishment would be the second highest rate of imitation
- punishment would be the lowest rate of imitation
- boys would be significantly higher than girls
number of participants and where from?
Participants were 33 boys and 33 girls from Stanford University Nursery School.
age range of ptps?
aged from 42-71 months old.
how were ptps divided?
randomly assigned to one of three conditions of
11 boys and 11 girls each. Two adult males served as role models and one female experimenter
conducted the study for all participants.
what happened when initially participants were brought into a semi-darkened room ?
- the experimenter said they had some business to attend to to before they could go into the ‘surprise
playroom’, but that during the wait, the child could watch a TV program.
what happened as the experimenter left the room
the experimenter turned on the TV and then left the room. The film lasted 5 minutes, within which the model walked up to an adultsized plastic Bobo doll and ordered him to move out of the way.
in the control no reward condition what did the model do to the bobo doll?
sat on it and punched it in the nose while remarking “Pow, right in the nose, boom, boom”; the model then raised the Bobo doll and pommeled it on the head with a mallet saying things like “Suckeroo….stay down”. This sequence was repeated twice.
- In the control group there was no reinforcement ending.
what happened in the reward condition
For participants in the model-reward condition, a second adult then appeared with a large supply of
sweets and drinks. He informed the model that he was a “strong champion” and that his superb
aggressive performance clearly deserved a treat.
what happened in the model punishment condition?
For participants in the model-punished condition, a second adult appeared and started wagging their
finger whilst saying “Hey there, you big bully. You quit picking on that clown. I won’t tolerate it.” As
the model drew back, he tripped and fell; the second adult sat on the model and then spanked him
with a rolled-up magazine while reminding him of his aggressive behaviour.
