-In the study by Bandura, Ross and Ross on aggression, 48 students are used as the participants. They are separated into aggressive and non-aggressive groups which were then separated into four groups of boys/girls with same sex/different sex models. The children were observed to see if they would imitate the models and what was found was that physical aggression was imitated, girls were more likely to show verbal aggression than boys if the model was female, boys were more likely to show physical aggression than girls, the boys in the aggressive conditions were more likely to be aggressive if their models were boys also, the girls were more likely to show more physical aggression if the model was male, and children also conducted non imitative physical aggression.
