Psychology 3720F/G Chapter Notes - Chapter 3: Relational Aggression, Protective Factor, Longitudinal Study
Chapter 3: development of aggression and individual differences. Development of aggressive behaviour in childhood and adolescence. Emergence and manifestations of aggression in childhood and adolescence. The first precursors of individual differences in aggression emerge very early at about 3 months of age. Cardiff infant contentiousness scale was developed to address six aspects of the use of physical force in social interactions and the expression of anger in babies. Reports elicited from parents and other informants when the children were 5 to 8 months of age predicted the use of physical force against peers when 11 to 15 months old. Boys in early school years show higher levels of physical aggression than do girls who are more likely to engage in relation forms of aggression. Card, stucky, sawalani and little: found that only direct aggression was uniquely related to externalising problems, such as emotional deficits and delinquency, whereas indirect aggression was uniquely associated with internalising problems.
