The study
by two Michigan State University psychologists refutes the popular theory that
how adults parent their children is strictly a function of the way they were
themselves parented when they were children. While environmental factors do
play a role in parenting, so do a person's genes, says S. Alexandra Burt,
associate professor of psychology and co-author of a study led by doctoral
student Ashlea M. Klahr.
"The
way we parent is not solely a function of the way we were parented as
children," Burt said. "There also appears to be genetic influences on
parenting." Klahr and Burt conducted a statistical analysis of 56
scientific studies from around the world on the origins of parenting behavior,
including some of their own. The comprehensive analysis, involving more than
20,000 families from Australia to Japan to the United States, found that
genetic influences in the parents account for 23 percent to 40 percent of
parental warmth, control and negativity towards their children.
"One
of the most consistent and striking findings to emerge from this study was the
important role that children's characteristics play in shaping all aspects of
parenting," the authors writes.
