WHAT'S KNOWN ON THIS SUBJECT: Previous research has shown the following: the mere presence of weapons can increase aggression, dubbed the "weapons effect"; violence in films has increased over time; and violent films can increase aggression.
WHAT THIS STUDY ADDS:This study examines a potential source of the "weapons effect": the presence of guns in films. In just 20 years, gun violence in PG-13 films (age 131) has increased from the level in films rated G/PG to the point where it exceeds the level in R films. abstract BACKGROUND: Many scientific studies have shown that the mere presence of guns can increase aggression, an effect dubbed the "weapons effect." The current research examines a potential source of the weapons effect: guns depicted in top-selling films.
METHODS:Trained coders identified the presence of violence in each 5-minute film segment for one-half of the top 30 films since 1950 and the presence of guns in violent segments since 1985, the first full year the PG-13 rating (age 131) was used. PG-13-rated films are among the top-selling films and are especially attractive to youth.
RESULTS:Results found that violence in films has more than doubled since 1950, and gun violence in PG-13-rated films has more than tripled since 1985. When the PG-13 rating was introduced, these films contained about as much gun violence as G (general audiences) and PG (parental guidance suggested for young children) films. Since 2009, PG-13-rated films have contained as much or more violence as R-rated films (age 171) films.
CONCLUSIONS:Even if youth do not use guns, these findings suggest that they are exposed to increasing gun violence in top-selling films. By including guns in violent scenes, film producers may be strengthening the weapons effect and providing youth with scripts for using guns. These findings are concerning because many scientific studies have shown that violent films can increase aggression. Violent films are also now easily accessible to youth (eg, on the Internet and cable). This research suggests that the presence of weapons in films might amplify the effects of violent films on aggression. 3 In theater, scripts tell actors what to do and say. In memory, scripts define situations and guide behavior; the person first selects a script for the situation, assumes a role in that script, and then behaves according to it. A script may be learned through direct experience or by observing others, such as violent characters in the mass media. 4 The media provide scripts for gun use. Gun violence in films might also encourage an association between guns and violence.In the wake of recent shooting sprees, legislators and the lay public are discussing possible ways to reduce youth violence. What is conspicuously absent from these discussions, however, is the fact that just seeing a weapon can increase aggression, an effect dubbed the "weapons effect."Guns not only permit violence, they can stimulate it as well. The finger pulls the trigger, but the trigger may also be pulling the finger.Leonard Berkowitz, Psyc...
