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 our of Duke University shows. Elizabeth Gershoff, associate professor in human development and family sciences, said the study adds to a growing body of research showing negative effects of spanking. "Almost all the studies point to negative effects of spanking," Gershoff said. "It makes kids more aggressive, more likely to be delinquent and to have mental health problems."
