Children who receive corporal punishment show a lower IQ in the world, according to research from the University of New Hampshire filed today in California.
"All parents want smart children," said Murray Straus, author of the study and participated in the 14 International Conference on Violence, Abuse and Trauma in San Diego.
"This research shows that if you avoid physical punishment and corrected in other ways, bad behavior can make children smarter," he added. "The results of this study have important implications for welfare of children around the world. "
Straus and Mallie Paschall, Pacific Institute for Research and Evaluation studied nationally representative samples of 806 children from 2 to 4 years old and 705 aged 5 to 9 years. Both groups were assessed again four years later.
The IQs of children ages 2 to 4 years who did not receive corporal punishment was five points higher four years after the IQ of those who received corporal punishment.
The IQs among children 5 to 9 years free of corporal punishment were 2.8 points higher four years after the children of the same age group who had experienced corporal punishment.
"How often punish parents makes a difference," said Straus. "The more frequent or severe the punishment, the slower the development of the child's mental ability."
Straus was also established that IQ is lower in countries where it is most common physical punishment of children.
For this part of the study Straus and his colleagues used data from 32 countries on corporal punishment experienced by 17,404 college students as children.
Straus said that corporal punishment is extremely stressful and could become a cause of chronic stress for children who typically suffer three or more times per week. For many of these children, the punishment continues for years.
