Abstract:  Reviews and presents data from several recent longitudinal studies, including one study that spanned 22 yrs, conducted by the present authors and colleagues (in press), that suggest that aggression is stable over time and situation. Results of the 22-yr study of 600 Ss who were 8 yrs old at the beginning of the study indicate early measures of intellectual competence predicted concurrent and later aggression, but early aggression was independently a good predictor of reduced intellectual achievement as an adult. Results of a 3-yr study conducted by the present authors and colleagues (in press), of over 800 primary school children found that cognitive rehearsal of aggressive behaviors predicted overt aggression, was predicted by overt aggression, and correlated with the child’s TV viewing. In combination, these data suggest a circular process in which scripts for aggressive behavior are learned at an early age and become more firmly entrenched as the child develops, so that aggression becomes self-perpetuating in children with certain cognitive characteristics.
