To spank or not to spank? That's been a question facing parents for generations. But a new study points out negative results from corporal punishment on children.
The Columbia University study showed that spanking could affect a child's behavior and learning ability for years to come, and actually caused aggressiveness in children, rather than diminishing it.
Researchers found that children spanked as five-year-olds were slightly more likely to break rules and be aggressive toward others later in their school years.
The study also showed that spanking apparently impeded learning among children punished in that manner.
Children who had been regularly spanked at the age of five scored lower on vocabulary tests.
These results are not a big surprise, as previous research has shown similar results.
Researchers say that spanking merely models aggressive behaviors, and makes kids think that violence is an effective problem-solving measure.
The lead author of the study said that despite much research showing spanking to be detrimental, the practice is still very common among U.S. parents
The study used data from a long-term study of children born U.S. cities between 1998 and 2000. It is published in the journal "Pediatrics."
