The procedure of Bandura begun when the children were__________ in their nursery school **prior** to the experiment. They were rated on **four ___-point scales** measuring **physical aggression, _________aggression, aggression to inanimate objects and aggression ___________ (anxiety)**. They were then assigned to __________ groups to **match their aggression levels**. Of the **51 children** rated by **both observers** *(the rest were rated by only one observer)*, there was ‘inter-rater reliability’, which showed a high correlation between the observers, of r =_______
________ boys and_________ girls were allocated to **control** **groups** who saw no model. The remaining children were divided _________ by **sex** between **aggressive and non-aggressive model groups** and within those, between **same and opposite-_________ models**.
The experimental procedure started with all participants being **deliberately mildly annoyed**:
Each individual child was shown to a room with toys but after about **two minutes of play**, they were told that these were the best toys that are kept for other children. The experimenter and child then moved to the _____________ room, where the experimenter showed the child to a table and chair in their ‘play area’, where they were shown how to make potato prints and sticker pictures. The opposite corner of the room also contained a table and chair, a Tinkertoy set, a mallet and a **five foot Bobo doll**. This is where the _________sat in applicable conditions. The experimenter **remained in the room** and appeared to be working quietly at their desk.
The three groups were then treated **differently.**
* In the ___________ condition, the **model assembled the Tinkertoys for _______** minutes.
* In the **aggressive condition** this lasted only _______ minute after which the model ________ the Bobo doll. This sequence was performed **three times over nine minutes** accompanied by aggressive comments such as ‘Kick him’ and two non-aggressive comments such as ‘He sure is a tough fella’. Of children in the model groups, _______ saw a same-sex model, the others saw a model of the opposite sex.
* A ________ group did not see any model, and therefore saw no aggression.
A test of the child’s aggression then followed in which the child was observed for ________ minutes using a **one-way mirror**. This **experimental room** contained a **three foot Bobo doll**, a mallet and peg board, etc. It also contained ___________ toys, including a tea set, crayons and coloring paper, a ball, two dolls, three bears, cars and trucks, and plastic farm animals. These toys were always presented in the same order.
The children’s behaviors were observed in **five second intervals** (_____ response units per child). There were **three ‘response measures’** of the children’s imitation, with a range of possible activities in each:
**• Imitation of** ___________ **aggression: striking the Bobo doll with the mallet , sitting on the doll and___________ it, kicking the doll, and tossing it in the air.**
**• Imitative __________ aggression: repetition of the phrases,** ***‘Sock him’, ‘Hit him down’, ‘Kick him’, ‘Throw him in the air’ or ‘Pow’***
**• Imitative ____________ verbal responses: repetition of** ***‘He keeps coming back for more’ or ‘He sure is a tough fella’***
\
Partially imitative aggression included:
**• mallet aggression: striking objects other than the ______ aggressively with the mallet**
**• sits on Bobo doll: laying the Bobo doll on its side and sitting on it, ________ attacking it.**
Two further categories were:
**• ________ gun play: shooting darts or aiming a gun and firing imaginary shots at objects in the room.**
**• ___________ physical and verbal aggression: physically aggressive acts directed toward________ objects and any hostile remarks not in the verbal imitation category** ***‘Shoot the Bobo’, ‘Cut him’, ‘Stupid ball’, ‘Horses fighting, biting’ ‘Knock over people***’
Finally, behavior units were also counted for **nonaggressive play** and sitting quietly **not playing at all**, and records were kept of the children’s ____________ about the situation.
**One male scored** all the children’s behaviors and, except for those conditions in which he was the model, he was _______ of which condition the child had been in **(although this was typically obvious in the case of the aggressive model children as they performed the very specific behaviors exhibited by the model).**
To test his __________, a **second scorer independently rated** the behavior of half of the children and the reliability was **high**, around r =________ for different categories of behavior.
