The influence of locus of control and aggressiveness of rock music videos on aggression: A reanalysis and methodological critique of Wann and Wilson (1996)

The present study reexamines the ANOVA results of a previous study (Wann & Wilson, 1996), and arrives at a different set of conclusions concerning the role of music video violence and locus of control on aggressiveness. Contr ary to the previous report, there is evidence of a significant main effect of locus of control on aggressiveness. Although the analyses of the main ef fect of music video and the interaction were nonsignificant, effect size da ta suggest that such effects would have been significant had the original s tudy been larger (N = 28). Given the paucity of research examining the effe cts of music video violence on aggression, the reanalysis of the Wann and W ilson (1996) data suggests that carefully controlled experimental research in this area would be fruitful.
