Wayne State researcher finds possible clue to children's early antisocial behavior
Date:12/10/2012

DETROIT - Both nature and nurture appear to be significant factors in early antisocial behaviors of adopted children, a Wayne State University researcher believes.

The EGDS is aimed at investigating how families can help their children develop to their fullest potential.

In "Examining the Interplay of Birth Mothers' and Adoptive Parents' Antisocial Behavior in Predicting Growth in Externalizing Problems During Early Childhood," adoptive parents' antisocial behavior played an important role in the development of children's externalizing problems. His study was presented at the 2012 meeting of the Behavior Genetics Association in Edinburgh, Scotland.

That finding may not come as a surprise to researchers who have studied environmental precursors to such behavior. However, Trentacosta said a great deal of other research that examined sets of twins holds that genetic factors play a role as well.

Part of the problem with environmental studies, he said, is that the people providing the parenting are the same ones providing the genes. Using an adoption design, Trentacosta said, allows researchers to disentang
