Abstract:  Examined the prediction that subjects with scores indicating an external locus of control (LOC) would have heightened scores on aggression after exposure to excerpts of aggressive music videos. First, Ss scoring in either the top 30% (internal LOC) or the bottom 30% (external LOC) on a pretest with Rotter’s LOC scale were selected for the study. These Ss completed the Buss-Durkee Hostility Inventory, and were then randomly assigned to view excerpts from either 3 aggressive music videos or 3 nonaggressive music videos. After viewing the videotapes, Ss again completed the hostility scale. Results did not confirm the hypothesis: no statistically significant differences were found between aggressive video/external LOC, nonaggressive video/external LOC, aggressive video/internal LOC, and nonaggressive video/internal LOC groups.
