One-third of Parents Lack Facts about Child Development
One-third of parents of babies have a surprisingly low knowledge of child development,in-cluding basic concepts about what their children should know or how they should act,a new study finds.
For instance,the study found that many parents don't know that 1 -year-olds can't tell the difference between right and wrong,and often don't cooperate or share when playing with other children.
The results are surprising because the parents who took part in the survey had young chil- dren,said lead author Dr. Heather Paradis,a pediatric fellow at the University of Rochester Med-ical Center in New York.“They were watching or had just watched their kids go through this de-velopment,and they were probably the most knowledgeable of anybody.”
Paradis and her colleagues examined the results of a survey of parents—98 .6 percent of whom were mothers—of more than 10,000 9-month-old babies. As part of the survey,the parents were asked 1 1 questions designed to test their knowledge of a baby's development.
The researchers also examined what the parents said about their interactions with their chil- dren,and watched videotapes of how the parents taught new things to their kids.One-third of those surveyed incorrectly answered four or more of the questions.Even when the researchers ad-justed the statistics to account for such factors as education levels and income,those parents were still less likely to enjoy“healthy interactions”with their children.
A lack of proper understanding of a child's development can cause assorted problems,Para-dis said. For example,she said,a mother might expect an 18-month-old child to sit still for a doctor's appointment,even though children that age are normally curious and like to wander around.
“A mom could misinterpret a child's normal curiosity as intentionally being defiant,and could respond with harsh discipline,withdrawal of affection and repetition of that pattern over time,”Paradis said.“That could hinder the child's potential for full growth and development.”
The findings were to be presented Sunday at the Pediatric Academic Societies' meeting in Honolulu.
One solution,Paradis said,is for pediatricians to take a more active role in educating new parents.“By improving knowledge of child development among all parents,not just those who are at highest risk,there's an opportunity to enhance parent-child interaction,”she said.“It can ul-timately lead to better parenting.”
Children of one and a half years old like to sit still.

If the Federation of
American Scientists made a list of educational video games, you might expect to
find Oregon Trail, the story of Conestoga wagons trekking into the American
West, or the geography favorite Where in the World Is Carmen Sandiego And don’t
forget Half Life 2. That’s the one where you burn alien zombies to death with
exploding barrels of fuel.
OK, that’s exaggerating--but only a
little. Where parents see hours wasted in front of a screen, these scientists
see potential. An FAS study released this week, titled "Harnessing the Power of
Video Games for Learning," reports that best-selling games are built in
