The Effects of Television Violence on Antisocial Behavior: A Meta-Analysis1

Abstract

A meta-analysis is performed on studies pertaining to the effect of television violence on aggressive behavior. Partitioning by research design, viewer attributes, treatment and exposure variables, and type of antisocial behavior, allows one to interpret computed effect sizes for each of the variables in the partitions. We find a positive and significant correlation between television violence and aggressive behavior, albeit to varying degrees depending on the particular research question. According to research design, we find ZFisher values ranging from .19 for survey to .40 for laboratory experiments. Erotica emerges as a strong factor even when it is not accompanied by portrayal of violence. Additionally, the effect of television violence on the antisocial behavior of boys and girls is found to be marginally equal in surveys. A host of tests are performed to solidify these, and further results. Substantive interpretation is provided as well.
