"There is literature that shows the prosocial effects of media on children, the authors ignore these reports," he told Fox News [http://www.foxnews.com/scitech/2011/10/17/swearing-on-tv-linked-to-teen-aggression/]. "The authors make no case for profanity being beneficial, as in humor elicitation, or social bonding, or as a coping mechanism, or as a relief from pain."
As usual, the problem is that both the good
and the bad effects share the same root cause -- and neither side is acknowledging that.
Why does swearing lead to increased aggression?
Because it indicates the initiation of an excited emotional state, in which aggression is more likely to appear.
Why does swearing lead to increased "humor elicitation" or pain tolerance?
Because it indicates the initiation of an excited emotional state, in which emotional influence (like humor) carries a bit more weight (it's easier to shove a car off-course when it's already moving, after all) or an increase in certain pain-management hormones (not the least of which is adrenaline).
So, the "big news" here is that anything that we associate with an excited emotional state will
put us in that state. And when we're in an excited emotional state, we are more heavily influenced by a lot of other things. There's no real "disagreement," but there's also not much of value here.
