A Study of Signing and Memory

Ask a parent what signs they are most anxious for their children to learn and the answer is likely to be EAT, DRINK, MORE, and ALL DONE—the “Mealtime Signs.” There’s no doubt that these signs are important to both parent and child, but other signs are important as well. Babies use signs for all sorts of reasons besides wanting to eat or drink. One of my favorite uses of signs is to enable babies to talk about their memories.

It comes as a surprise to many parents (and many researchers) that babies and toddlers are, indeed, capable of laying down memories for salient experiences and retrieving those memories after a considerable time. We tested this capacity ourselves in our lab at the University of California at Davis a decade or so ago. Here’s what we did.

Fourteen-month-olds were invited to our lab for a study about signing. While the parent and child were waiting for the experiment to begin, they were in a room with a live mouse named “Mickey” contained in a colorful “house” cage. Not surprisingly, the children were inevitably drawn to the mouse.

When the experiment itself began, the mouse was removed and parents were asked to try teaching a set of signs to their child over the next 2 months. The signs represented different categories (e.g., requests, nouns, adjectives) and included the sign for MOUSE. The parents were told we were interested in which signs were more easily learned.

In reality, the experiment was a test of whether the babies would use a sign to indicate a memory. Specifically, when the families returned to the lab 2 months later there was no mouse in the room and our video cameras filmed the children to see if they would use the MOUSE sign to ask about it, thereby indicating that they remembered the presence of Mickey during their earlier visit.

What did we find? Yes, indeed, we saw enough of the toddlers sign MOUSE with quizzical expressions (or even combined with a WHERE? sign) that we knew we had succeeded! Toddlers can indeed remember an event that occurred 2 months earlier and can use a sign to “say” so!

So, resist the temptation to stop with the Mealtime Signs. Teach signs for lots of other things your baby might want to talk about—and remember!

The American Academy of Pediatrics on Media and Babies

Just last week I gave a webinar for our Baby Signs® Instructors that focused on the American Academy of Pediatrics’ position in regard to TV/Videos/DVDs for children under 2. As many responsible parents know, the AAP went on record about 2004 with a recommendation against any TV-type viewing for this young age group.

The issue is important to us here at Baby Signs because we have 6 DVDs designed to teach signs to babies. We produced these DVDs specifically for babies—that is, with very simple vocabulary and images, slow action, animated characters and real babies, and lots of repetition of the signs. What’s more, they work! Babies love them and both they and their parents learn signs from them.

Back to the AAP. What has been the result of the 2004 prohibition? Quite simply, irresponsible parents continue to expose their children to hours and hours of TV, while responsible parents feel guilty about even the smallest amount of such viewing they allow their babies. It’s become a “dirty little secret” that Mom puts on a DVD to gain 30 minutes of respite from supervising her toddler.

What many parents don’t know, however, is that the AAP relaxed its position in a 2011 up-date. In their own words, “The AAP realizes that media exposure is a reality for many families in today’s society. If parents choose to engage their young children with electronic media, they should have concrete strategies to manage it…. It is important to set limits and create balance at an early age” (2011, p. 4).

We certainly can’t argue with that! We also can’t argue with another of their observations—that many DVDs purporting to be “educational” really aren’t. That’s where the Baby Signs® DVDs shine! We know they teach signs to the babies, and we know from our federally-funded research that signing promotes language and intellectual development. In other words, we know they are truly “educational!”

In fact, the AAP itself has endorsed signing. Here’s a statement from their 2011 book, Heading Home with Your Newborn: “Infant sign language really does deliver on its promise of improved communication….It’s easy to see why so many parents swear by it, why child care centers include it in their infant and toddler classrooms, and why it has become so commonplace as an activity of daily learning” (p. 173-174).

Conclusion: While parents should, indeed, set limits on TV/DVD viewing by their babies and toddlers, at least in the case of the Baby Signs® DVDs, they need never feel guilty about gaining 30 minutes of peace and quiet by turning one on!

Playing Pretend: Talk about Fun!

baby sign language

Just last week in this blog I took a detour from talking about to discuss how important pretend play is to children’s cognitive development. The point I made then is that playing pretend encourages a form of mental “gymnastics;” the child is learning to keep in mind not only what he or she is doing in the present (e.g., feeding a bottle to the doll) but also that the doll represents a real baby and the pretend milk represents real milk. That’s not something a 12 month old can do, but by 18 months, the development of this kind of mental flexibility is underway.

Well, here’s another benefit of pretend play for your child’s development. Research shows that helping children engage in pretend play is an easy way for parents to support language development. In this case, what we’re talking about here is participating with your toddler or preschooler in pretend scenarios—like talking to Grandma on a toy phone, pretending to make and eat imaginary foods, playing with dolls or trucks in ways that involve imagination.

Why does not only encouraging but actually participating in this kind of play with your toddler or preschooler benefit language learning? The answer is because pretend play is language rich when parents are involved—both in terms of language you say to your child while playing and language your child says to you in response. For example, a tea party with your child might introduce new vocabulary words like cups and saucers, tea and teapot, the names of friends or new foods, etc. Or play with a toy plane might involve words like take-off, landing, pilot, the names of destinations. In addition, your questions to your child (for example, “Who are you inviting to our party?” or “Where is the plane going?”) require your child challenges your child to draw from his or her existing vocabulary to provide appropriate answers. In other words, these kinds of pretend interactions help children learn to both understand more language and to talk themselves.

So, whether your child is into tea parties or trucks, baby dolls or train tracks, make it a point to get down to his/her level (both figuratively and literally) and join the fun. Who knows? You might actually have fun exercising your own imagination!
