A new study finds that spankings may lower a child's IQ.
The study from the University of New Hampshire found that spankings lowered
children's performance on intelligence tests by several points.
"The more spanking, the slower the development of the child's mental ability," lead study author Professor Murray Straus said in a news release. "But even small amounts of spanking made a difference."
Straus and his fellow researchers tested roughly 1,500 children at the beginning and end of their four year study.
