TUESDAY, Sept. 15 (HealthDay News) -- Children who are spanked as 1-year-olds are more likely to behave aggressively and perform worse on cognitive tests as toddlers than children who are spared the punishment, new research shows.
Though the negative effects of spanking were "modest," the study adds to a growing body of literature that's finding spanking isn't good for children.
"Age 1 is a key time for establishing the quality of the parenting and the relationship between parent and the child," said study author Lisa J. Berlin, a research scientist at the Center for Child and Family Policy at Duke University. "Spanking at age 1 reflects a negative dynamic, and increases children's aggression at age 2."
The study is published in the September/October issue of Child Development.
