11 boys and 11 girls each. Two adult males served as role models and one female experimenter
conducted the study for all participants.

Question 5

what happened when initially participants were brought into a semi-darkened room ?

Answer 5

• 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.

Question 6

Answer 6

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.

Question 7

in the control no reward condition what did the model do to the bobo doll?

Answer 7

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.

Question 8

what happened in the reward condition

Answer 8

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.

Question 9

what happened in the model punishment condition?

Answer 9

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.
