Children Who Get Spanked Have Lower IQs

Children Who Get Spanked Have Lower IQs

Spanking can get kids to behave in a hurry, but new research suggests it can do more harm than good to their noggins. The study, involving hundreds of U.S. children, showed the more a child was spanked the lower his or her IQ compared with others.

"All parents want smart children," said study researcher Murray Straus of the University of New Hampshire. "This research shows that avoiding spanking and correcting misbehavior in other ways can help that happen."

One might ask, however, whether children who are spanked tend to come from backgrounds in which education opportunities are less or inherited intelligence lower.

But while the results only show an association between spanking and intelligence, Straus says his methodology and the fact that he took into account other factors that could be at play (such as parents' socioeconomic status) make a good case for a causal link.

"You can't say it proves it, but I think it rules out so many other alternatives; I am convinced that spanking does cause a slowdown in a child's development of mental abilities," Straus told LiveScience.

Intelligence quotients

Straus and his colleague Mallie Paschall of the Pacific Institute for Research and Evaluation in Maryland studied nationally representative samples of two age groups: 806 children ages 2 to 4, and 704 ages 5 to 9. The researchers tested the kids' IQ initially and then four years later.

Both groups of kids got smarter after four years. But the 2- to 4-year-olds who were spanked scored 5 points lower on the IQ test than those not spanked. For children ages 5 to 9, the spanked ones scored on average 2.8 points lower than their unspanked counterparts.

The results, he said, were statistically significant. And they held even after accounting for parental education, income, cognitive stimulation by parents and other factors that could affect children's mental abilities.

Straus will present the study results, along with research on the relationship between average national IQ and prevalence of spanking around the world, Friday at the 14th International Conference on Violence, Abuse and Trauma, in San Diego, Calif.

Spanking science

Whether or not spanking equates with dumber kids is not known, and may never be known. That's because the only way to truly show cause and effect would be to follow over time two groups of kids, one randomly assigned to get spanked and another who would not get spanked. Barring that method, which is unfeasible, Straus considers his study the next best thing, as he looked back at a nationally representative set of kids who were followed over time.

Jennifer Lansford of Duke University's Center for Child and Family Policy and Social Science Research Institute called the study "interesting," and agrees the method is a strong one. Lansford, who was not involved with the study, said following kids over time as this study did rules out the possibility that children with lower IQs somehow elicit more physical discipline.

However, unlike research showing the link between spanking and a kid's aggressive behavior, in which kids model parents' actions, this link is less clear to her. She added that a question still left unanswered is "what are some of the other mechanisms that could be responsible for this link between physical discipline and lower IQ?"

How spanking harms

If spanking does send IQ scores down, Straus and others offer some explanations for what might be going on.

"Contrary to what everyone believes, being hit by parents is a traumatic experience," Straus said. "We know from lots of research that traumatic stresses affect the brain adversely." Also, the trauma could cause kids to have more stressful responses in difficult situations, and so may not perform as well cognitively.

By using hitting rather than words or other means of discipline, parents could be depriving kids of learning opportunities. "With spanking, a parent is delivering a punishment to get the child's attention and to get them to behave in a certain way," said Elizabeth Gershoff who studies childhood development at the University of Texas, Austin. "It's not fostering children's independent thinking."

So when a child gets in a bind, he or she might do the right thing to keep from a spanking rather than figuring out the best decision independently, added Gershoff, who was not involved in Straus's current study.

And then there are genes, as some kids are just born smarter than others.

Even though spanking has been shown to cause negative consequences, Gershoff said many parents still fall back on the behavior-shaping tool. As for why, she says it's a quick fix, though its seeming success is short-lived and the negative consequences often outweigh the positives. Parents also might have been spanked themselves and so continue the tradition.


Comments:
This is pure B.S.! If spanking lowered IQ's, then over 3/4 of the US would be mentally retarded in some form. In fact, why would a person use babies for an IQ test? Elementary children make gains over the total time of their schooling grades 1-12. In fact, I believe the opposite is true. If you don't spank them, they will have low IQ's. Why? They have no initiative to accomplish anything. If fact, I think that within the next 10 years, folks will get a real eye-opener about what their "lax" or "non-existent" parenting has done for the education system in this country. In fact pair this with "No Child Left Behind" and you can get a picture. Schools can't make the students do their work so the teachers do it for them so they can "pass". This in turn keeps the schools off of the dreaded NCLB "Hit List". When the child graduates and goes to college, the college gives them a tutor to help write sentences (simple ones) and to help them with their math (high school level because they were too busy doing other things). If this student manages to graduate from college, he or she may be your Docor, Lawyer, Mayor, President.
so,einstein was never spanked!
Bull.
Children who were never spanked are more likely to become "know it alls" and also land in jail!! Statistic pulled straight from me own arse!!!
Uh-huh. This is why you have a generation of parents afraid of their children, instead of the other way around.
If you don't raise your children, the sheriff will - and the taxpayers will get the bill.
Well, I'm a perfect example that this study is totally unfounded. My parents beat the &%$# out of me and I'm brilliant. LOL :-)

However, I do not believe in hitting children.
Can't believe they didnt have nothing to do, they went in lenghts over this experiments, yet they could experiment how children "LISTEN" because the literature that's out there about is crappy...
There is almost no literature research about how children and little kids "LISTEN" AND LEARN...
