Abstract: Reports a study, previously synopsized in the journal, testing the idea that some persons have a characteristic of being extra susceptible to the influence of filmed models. 38 boys, 61-75 mo. old at the start of the experiment, were shown films of aggressive acts. Imitative behavior was observed during subsequent play periods and found to be highly correlated from the 1st film to the 2nd. It is concluded that children will consistently imitate aggression seen in films even though the characters and settings are varied. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
