A study recently conducted in the University's psychology department shows that disruptive behavior in children may have genetic origins rather than simply stemming from exposure to factors such as familial interactions.
The study analyzed the connection between conflict within a marriage and children's conduct disorder, said Paige Harden, a psychology graduate student leading the research.
Specifically, the purpose of the study was "to find out... whether it was the marital conflict itself that caused the problem" or whether it was the result of "parents with genetic liabilities" who then pass these genes on to their children," Harden said.
What the researchers found was that behavioral problems do have a genetic component, she said.
The study describes this specific relationship in genetic terms, and examines the effects of marital friction on children's development.
According to the study, "there are not genes 'for' arguing with a spouse, but the process of selecting, shaping, and perceiving social environments involves genetically-influenced behaviors and personality attributes."
The research was conducted by observing samples of identical twins "who differed in their marital conflict," Harden said.
