1. [1 mark per correct feature] 72 participants. 36 male and 36 female. All were selected from the Nursery School of Stanford University. Ages ranged from 37 months (just over three years) to 69 months (five-and-three-quarter years). The mean age was 52 months (four years and four months).
2. [1 mark for valid point made about real world application (2nd mark from elaboration/detail) Or 1 mark for a result or part of procedure that would be useful in the real world 1 mark for how it can be used by/applied to adults] As the study showed that aggression can be observed and imitated (1 mark), TV networks might want to either censor the content of TV programmes (1 mark). Ensure that there are warnings on TV shows about the level of aggressive content (alternative 1 mark) or allows parents to choose what their children should/should not watch (on the TV) (alternative 1 mark).
