Do you believe that violence in the media causes aggression? (What does the word cause mean?) Media violence is everywhere-not only in R-rated films but also in Grated films and in video games. There are connections between media violence and aggression, but not everyone who witnesses media violence behaves aggressively. How, then, do we explain the connections between violence in the media and aggression? Please write a 2 paragraph response. Your first paragraph should focus on the relationship between viewing violence and aggressive behavior (talk about the role of causation here). The second paragraph should focus on how we can try to mitigate the likelihood of aggressive behavior even when children view media violence. Learning Objectives: - Understand the meaning of causation in variable relationships - Describe the impact of media violence viewing on aggressive behavior - Discuss ways to reduce the risk of aggressive behaviors
