Genetic Roots of Anger

Thanks to HenryZ who sent me this article from Scientific American, ” Taming Baby Rage: Why are Some Kids More Angry?”

The article looks at the nuerobiological roots of anger. According to the article a child’s anger peaks at 18 months (biting, hitting, scratching, tantrums) and tapers as the child learns to play with others during the ages of 2-5.

The article suggests that the angry behavior is caused by some genes “not being expressed”– the genes are damaged during pregancy. For example a child whose language genes are damaged might become frustrated that he or she can’t express needs and lash out.

Researchers say their next step is to identify genetic profiles that would help identify chronically aggressive children earlier.
