In the study of the transmission of aggression by Bandura et al. (1961), a matched participants design was implemented to control for individual differences. To achieve this matching, the children were rated beforehand by an experimenter and a nursery teacher on which specific set of pre-existing behavioural characteristics?
Chronological age, verbal intelligence (IQ), and pre-existing levels of physical and verbal aggression.
Pre-existing physical aggression, verbal aggression, aggression toward inanimate objects, and aggressive inhibition.
Frequency of cooperative play, sibling status (only child vs. having siblings), and history of nursery attendance.
Baseline levels of physical activity, reactivity to frustration, and obedience to adult instructions.
152 exam-style questions on OCR A Level Psychology External influences on children's behaviour, covering Bandura et al. (1961): Transmission of aggression and Chaney et al. (2004): Funhaller study. Each one has a worked solution and a mark scheme showing where the marks go.
