Bandura, Ross and Ross 1961

AIM - To see if children will immitate aggressive behaivour acts when given the oppurtunity even if they saw these in a different environment and the model is no longer present.

THE 4 HYPOTHESES 

1. p's exposed to agressive model would produce more immatative agressive acts than p's exposed to a non-agressive model and those not exposed to a model at all ( control grp)
2. Exposing p's to a non-agressive model would have an inhibiting effect on their agressive behaivours and they would show signiicantly less agression than the control grp.
3. assumed children had beeen reinforced into aproprate sex-role e,g, girls cooking being meternal. Children would be more likely ot copy the same sex model girls would copy women more and vice versa.
4. Bandura et al expected boys to immitate more agressive acts than girls, especially with same sex models.

THERE WERE THREE GROUPS 

72 children alltogetehr half boys half girls aged between 37 - 69 monts mean 52 months 

The roll models were one female and male adult.

all children sub divided into  subgroups of 6 each exposed to every possible condition e.g. boys exposed to a non-agressive female roll model. and 12 boys and girls 24 in total were the control group exposed to no roll model at all 24 p's in every condition 

INDEPENDANT VARIABLES - 

1. the condition the children were exposed to e.g. aggressive/ non-aggressive 
2. the genedr of the roll model 
3. the gender of the child 

EXTRANEOUS VARIABLES - ( before the study) 

Number of children 6 quite small results could be distorted if one grp contained say three normally aggressive children. e,g, if resaerchers found that boy grp exposed to male aggressive model were most aggressive this could of been the case as they were aggressive anyway!!!!

HOW DID THEY TRY TO RESOLVE THIS PROBLEM???

Pre- tested the p's for how agressive they were, by observing children in a nursery and judged their aggressivness byba 5 point rating scale and then similar p's were put in the same grps therefore regarded a matched pairs design.

INTER RATER RELIABILITY 

51 of the children were rated by two observers seperatley and then compared their observations they showed a very high reliability correlation r = 89 which suggested that the observers had good agreement about the behaivour of the children.

PROCEDURE - 

THREE ROOMS 

ROOM ONE 

• a table and chair in one corner with patatoe prints and a pic and stickers ( as children lik playing with them)
• The other cirner had a table with a…
