In this project, content analysis of violence and prosocial behavior appearing in Japanese TV fiction, news programs, and commercials (Japanese Television Violence Study : JTVS) were conducted. A panel study also examined the causal relationship between aggression and the tendency to view them, which referred to the framework of JTVS.We translated the National Television Violence Study coding book of the United States, and newly added verbal and indirect aggressions to physical aggression.

The analysis of commercials indicated that there were few portrayals of violence with harm and pain cues from violence, and more realistic violence. Prosocial behavior in both news and commercials showed more success of actions and More attractive characters in performers.Our panel study was conducted at thirteen elementary schools and at fifteen junior high schools in 2004 and 2005. The result indicated that viewing certain types of violent scenes showing violence with their body parts, or by attractive characters increased elementary school students' indirect aggressions. Also, viewing indirect aggressions on TV was suggested to have increased aggression of junior high school students.Based on the above-mentioned content analysis and panel study, we proposed an evaluation system which combined frequency of violent depictions with intense of causal effects between viewing them and aggression.
