Baby DVDs, Videos May Hinder, Not Help, Infants’ Language Development

Science Daily  Despite marketing claims, parents who want to give their infants a boost in learning language probably should limit the amount of time they expose their children to DVDs and videos such as “Baby Einstein” and “Brainy Baby.”

Rather than helping babies, the over-use of such productions actually may slow down infants eight to 16 months of age when it comes to acquiring vocabulary, according to a new study by researchers at the University of Washington and Seattle Children’s Hospital Research Institute.

The scientists found that for every hour per day spent watching baby DVDs and videos, infants understood an average of six to eight fewer words than infants who did not watch them. Baby DVDs and videos had no positive or negative effect on the vocabularies on toddlers 17 to 24 months of age. The study was just published in the Journal of Pediatrics.

“The most important fact to come from this study is there is no clear evidence of a benefit coming from baby DVDs and videos and there is some suggestion of harm,” said Frederick Zimmerman, lead author of the study and a UW associate professor of health services. “The bottom line is the more a child watches baby DVDs and videos the bigger the effect. The amount of viewing does matter.”
