The Immediate Effects of Media Violence on Behavior.

The purpose of this paper is to review experimental studies and short-term field investigations designed to assess the influence of violence in the mass media on aggressive behavior in the viewer. Major trends in research over three decades are examined. We also indicate some possible connections between research on effects of media violence and recent developments in cognitive psychology. The evidence is organized according to the theoretical explanations that have been given for the commonly reported correlation between the viewing of violence and aggressive behavior. The paper is divided into three major sections. In the first, evidence from laboratory experiments is reviewed. In the second section, studies carried out in field-experimental settings are summarized. In the third section, evidence from non experimental studies is analyzed. In our conclusion we suggest that the cognitive-neoassociationist hypothesis serves as the best explanatory model for the overall findings and we indicate how some of the other hypotheses concerning media effects on aggression may be subsumed by it.
