The issue of violent images is a hot-button issue across the media spectrum. Travis Dixon, an assistant professor in speech communication, has studied the impact of hip-hop music on audiences. He says that various studies indicate that after viewing a violent rap music video, young adults tended to be desensitized to a violent action and demonstrate a greater acceptance of it. But like the earlier video game research, most of these studies tend to measure short-term reactions.
"Maybe if we did a long-term, longitudinal study of rap music we'd find that there aren't any negative long-term effects of listening to rap, either," Dixon says. "That's very possible."
