LAS VEGAS — Recent economic woes in the United States may have triggered a temporary upturn in the use of harsh parenting methods by mothers carrying a particular gene variant.
Mothers who inherited either one or two copies of a particular form of the dopamine D2 receptor gene, dubbed DRD2, cited sharp rises in spanking, yelling and other aggressive parenting methods for six to seven months after the onset of the economic recession in December 2007, sociologist Dohoon Lee of New York University reported August 22 at the American Sociological Association’s annual meeting.
