Does Spanking Lower Kids' IQ?

Could spanking make a child less intelligent than kids who aren't?

A new study conducted by the University of New Hampshire seems to indicate this is the case.

CBS News medical correspondent Dr. Jennifer Ashton explained researchers found that spanking is associated with a lower IQ.

The study will be presented Friday at the Institute on Violence, Abuse and Trauma (IVAT), an international resource and training center at Alliant International University, in San Diego.

About 1500 children, Ashton explained, were studied in two different age groups. The researchers, she said, followed the children over four years, and then rechecked their IQs.

"Now, they all got a little bit smarter with age as we would expect with children," Ashton said. "However, those who were spanked had a slightly lower IQ than those who were not -- across both age groups."

Among children ages 2 to 4, there was a five point difference between children who were spanked and those that weren't. And among children from 5 to 9 years old, there was a 2.8 point difference between the two groups.

Also, the study controlled socioeconomic factors, Ashton said, such as the educational level of parents and income.

However, Ashton pointed out, the study found this was just an association -- not a cause-and-effect finding.

"I don't think it's going to keep anyone out of college," Ashton said. "But, again, the more we learn about the impact of things like spanking, the more things like this will be researched."

Ashton added there are also societal, cultural and generational factors, at play here, as well.

"Early Show" co-anchor Harry Smith joked if he wouldn't have been spanked on the behind all the time he could have been a genius.

Ashton said in her case, it's generational.

"My mother got out the wooden spoon. My father took his belt off," she said. "My husband and I choose not to spank our children."

Instead, Ashton said she grabs her kid's ear, and pinches it as an alternative.

She said, "That usually gets their attention."

All of these studies over the past 40 years have all been linked back to the same man: Murray Straus. In the 1960s, Straus wrote a pamphlet instructing parents to spank their toddlers with a stick. He often used the term \"beat\" when describing this process. Parents were outraged by this and they disregarded his advice after that, since it was pretty clear he was a child abuser. Ever since then Murray has conducted a billion different studies all with the same goal in mind: to prove spanking children is abuse. His purpose in conducting these studies is to save his reputation so he won't go down in history as a child abuser. These studies are ALL linked back to him. The only purpose in these is for him to earn credibility with the APA, and it really has nothing to do with your family or how you decide to discipline your kids. Murray's results are PURPOSELY skewed so he can shed his past reputation as a child abuser.

Yes, we were spanked a plenty, but we were dearly loved, and may that have been considered in this study? Yes, that made all the difference in our case where we were seven total. May I suggest, that today's spanking with life on the fast and faster lane, loving has actually no time in the American family falling apart faster and faster. Yes, over a million children are left in limbo yearly in America due to divorce. Yes, mothers are now forced to work etc., leaving true loving to strangers. Let me also suggest very strongly, that the fact that fewer and fewer children per family also says that children are really not truly welcomed; material things gattering is becoming overly important in this USA!

I was spanked when I was very young and the only thing that was altered was my behavior - for the better. My IQ did not suffer at all (I had an IQ of 164 when I was 20). There is nothing wrong with spanking if the situation calls for it. I've seen too many children and teenagers who were never spanked and their behavior is terrible as is their respect for their parents and other adults. We wonder why our society is so out of control and one of the answers is the lack of consistent discipline we give our children. Love your children, but discipline them and teach them right from wrong - and be consistent with what you teach them. Your children may not be happy now, but they will thank you when they are older.

Why in the world would the government stop spanking. I am sorry spanking you kids does not lowered their IQ. I was spanked growing up and I am not any dumber or have a lower IQ. I think this is the dumbest thing ever. If the government spent one day in my house they would understand why some kids need spanked. I have a very mouthy 12 yr old who think he can do whatever he wants and 2 very sassy smart mouthed 9 yr olds. So there is a time or 2 that my kids get spanked. And everyone wounders whats wrong with the world today. I am not saying abuse your kids but kids do need more guidence than others. And if spanking lowered their IQ's then my husband would be the stupid as ever. He was spanked all the time and my husband is not stupid by any means. I will be a firm beleiver in spanking and time out and grounding.

Most compelling of all reasons to abandon this worst of all bad habits is the fact that buttock-battering can be unintentional sexual abuse for some children. There is an abundance of educational resources, testimony, documentation, etc available on the subject that can easily be found by doing a little research with the recommended reads- visit www.nospank.net.

Just a handful of those helping to raise awareness of why child bottom-slapping isn't a good idea:

American Academy of Pediatrics,
American Academy of Child and Adolescent Psychiatry,
Center For Effective Discipline,
PsycHealth Ltd Behavioral Health Professionals,
Churches' Network For Non-Violence,
Nobel Peace Prize recipient Archbishop Desmond Tutu,
Parenting In Jesus' Footsteps,
Global Initiative To End All Corporal Punishment of Children,
United Nations Convention on the Rights of the Child.

In 26 countries, child corporal punishment is prohibited by law (with more in process). In fact, the US was the only UN member that did not ratify the Convention on the Rights of the Child.

Child buttock-battering vs. DISCIPLINE:

Child buttock-battering for the purpose of gaining compliance is nothing more than an inherited bad habit.

Its a good idea for people to take a look at what they are doing, and learn how to DISCIPLINE instead of hit.

I think the reason why television shows like "Supernanny" and "Dr. Phil" are so popular is because that is precisely what many (not all) people are trying to do.

There are several reasons why child bottom-slapping isn't a good idea. Here are some good, quick reads recommended by professionals:

mswolfestock,
Th scientist stated that there are exceptions. Consider the high percentage of children in Special Ed that are hit, verbally abused and neglected?These type of tests will help to prevent others like you as a child to stop the abuse.

Spanking will mold a child" Are we talking about jello or a person? Th at type of talk and physical assault of children is akin to slavery. I also was very upset that the reporter of the story mentioned pinching a childs ear. I believe she was teasing; however as some may convert from that because a medical professional condones it . we as viewers to to write to her CBS Morning How so that she can correct her statements!
