... a new study, co-authored by an Iowa State University psychology professor, ... found that onscreen relational aggression -- including social exclusion, gossip and emotional bullying -- may prime the brain for aggression.
"What this study shows is that relational aggression actually can cause a change in the way you think," said Gentile, who runs the Media Research Lab at Iowa State. "And that matters because of course, how you think can change your behavior."
"This matters because relational aggression tends to be considered more socially acceptable -- it's often portrayed on television as funny and how friends treat each other," he said. "Yet, several studies are starting to show that relational aggression can cause long-term harm."
One of the reason I so enjoy Atheist Nexus is that our norms suppress relational aggression, creating a safer cyber community.
