　　There is a popular saying in the English language: "Sticks and stones may break my bones, but names will never hurt me."

　　Well, that is not true.

　　Unkind words, name-calling or even the so-called "the silent treatment" can hurt children as much as being physically hit, sometimes even more so.

　　A recent study of middle school children showed that verbal abuse by other children can harm development in the brain. The study was a project of researchers at Harvard Medical School in Massachusetts.

　　Researcher Martin Teicher and his team studied young adults, ages 18 to 25. These young men and women had no experience with domestic violence, sexual abuse or physical abuse by their parents.

　　The researchers asked the young people to rate their childhood exposure to verbal abuse from both parents and other children. Then the researchers performed imaging tests on the brains of the subjects.

　　The images showed that the individuals who reported suffering verbal abuse from their peers in middle school had underdeveloped connections between the left and right side of the brain.

　　The two sides of the brain are connected by a large bundle of connecting fibers called the corpus callosum. This was the area that was underdeveloped.

　　The middle school years are a time when these brain connections are developing. So, unkind, hurtful comments from children or adults during this period had the greatest effect.

　　The researchers tested the mental and emotional condition of all the young people in the study. The tests showed that this same group of individuals had higher levels of fear, depression, anger and drug abuse than others in the study.

　　The researchers published their findings online on the American Journal of Psychiatry's website.

　　We cannot control what other people say to our children. But we can prepare them. A website called CreativeWithKids.com suggests 64 things that all children need to hear.
