A study published in Child Development, conducted at Emory University and sponsored by The Eunice Kennedy Shriver National Institute of Child Health and Human Development (a division of the National Institute of Health), revealed that infants under 2 can learn signs from television time.
While the American Pediatric Association (APA) issued earlier statements advising parents against it, putting your baby down for a few minutes’ worth of an educational video is not so bad after all.
During the course of the three-week long investigation which took place through the Video Learning Lab at Emory University, parents introduced their 15-month-olds to ASL signs at home, either through videos or a picture book.
The best piece of information gleaned from this study is that when it came to video viewing, babies who watched with parents for approximately 15 to 20 minutes recalled a significant number of the 18 signs presented.
They performed just as well as those who learned from books. In addition, those that watched videos alone (without a parent next to them), also retained a significant portion of the information.
The findings suggest that television time for tots is not as harmful as we’ve been led to believe for years.
Once a week, the Emory team quantified their subjects’ learning outcomes by having them pair pictures with their matching signs. Parents also reported each week whether they observed their babies using these signs.
When the three-week period ended, researchers retested the children one week later to determine what they were able to remember. Recall was assessed specifically by having the infants produce signs when they saw pictures of the objects, and by asking them to point to the picture that matched the signs.
A leading author of the study, developmental psychologist Shoshana Dayanim, Ph.D., explained that the study was unique for a variety of reasons: It was a controlled one wherein the only way for subjects to learn signs was through this study during its allotted time periods. While previous research has been conducted with infants and language, — a murky area where it is difficult to control what is learned — the Emory exploration consisted of approximately 15- to 20-minute intervals of exposure.
The study uniquely presented the babies with expressions to actually employ and simultaneously understand.
Dayanim further explained that infants use signs interchangeably with verbal words and can sign words earlier than they can vocalize them. This not only helps communication in the present tense, but research supports that signing positively impacts vocabulary in early childhood.
Knowing that the American Pediatric Association once advocated for keeping infants away from television altogether, it is interesting to see there are benefits to TV learning — in a controlled environment.
Dr. Dayanim made it clear that Emory was not declaring“Watch TV!”, but that under the right circumstances, instructional learning can actually take place through instructional videos with children under 2.
The one drawback of the study was that researchers were not able to determine exactly when to draw the line on video watching.
Parents may want to play it safe by keeping educational viewing to a minimum as the researchers did.
If a parent needs 15 to 20 minutes to unwind, explained Dayanim, their baby can actually learn something in the process.
Just don’t bother with sight words at such an early stage. The research only attests to success with signs.
