This document discusses research on the relationship between media violence and real-world aggression. Some key points made include that extensive research has found a link between viewing violent media and increased aggressive attitudes and behavior, especially in children and adolescents. However, the results are inconsistent and some factors like amount of time spent viewing and content can influence the effects. Studies have also found that exposure to media violence can increase desensitization to real violence but does not necessarily increase tendencies towards real-world violence.
