Signing in Action: A Hair-Raising Experience

One of our research findings, in fact, the finding that surprised us the most, was a significant effect of signing on intellectual development. When we tested the children from our federally-funded study when they were 8 years old, we found significantly higher IQs among those who had signed as babies compared to those who had not.

Why might that be? Well, the fact that we know signing provides a jumpstart to verbal language development is certainly an important factor. Another contributor, we believe, is that the signing provides babies a way to ask questions and gain information about the world around them well without having to wait for words. The following story—which was emailed to us years ago from a mom in the Netherlands—provides a great example. See what you think.

As 14-month-old Sam sat next to his mother on the bus, a young man with his hair in dreadlocks sat down across the aisle. Obviously fascinated, Sam turned to his mother and patted his head, his sign for HAT. “Oh, honey I know it looks like a hat, but it’s really hair,” whispered his mom, simultaneously rubbing some of her hair between her fingers, the sign for HAIR. Sam turned back to the man, stared intently, and again caught his mother’s eye, this time patting his head with more vehemence. By now the young man had become curious enough to ask what was going on. “My son thinks you’re wearing a hat and doesn’t believe me when I tell him it’s really your hair,” Sam’s mom explained. In response, the young man invited Sam to feel his dreadlocks for himself. So Sam did, and no sooner had his fingers touched the young man’s hair than Sam raised his hand to his head and with eyes wide with surprise rubbed some strands of his own hair between his fingers. The message was as clear as if he had spoken the words: “It is hair!”

Imagine such mini lessons multiplied throughout the day and you’ll have a sense of what I’m talking about. Signs enable babies to gather information about things they are specifically interested in, thereby helping them start amassing knowledge without having to wait for words. The cumulative effect is more advanced intellectual performance down the line.

This Little Piggy Went to Market

I recently posted in this blog a description of an experimental study I did at UC Davis to see if toddlers would use a sign to indicate that they remembered something that had happened 2 months earlier. (They did.) I certainly wasn’t surprised by our findings because I had long been hearing stories from parents indicating real life examples of babies using signs to indicate memories. Here’s one of my favorites:

A roly-poly potbellied pig was 15-month-old Brandon’s favorite exhibition at a street fair in a neighboring town he had never visited before. In fact, Brandon was so enchanted with the pig that he sued his sign for PIG (fingertip to nose) countless times during the day to let his parents know he wanted to see it again…and again…and again. His parents happily obliged, enjoying the fact that he could actually tell them what he wanted. But something even more amazing happened six weeks later. Brandon and his parents visited the town for a second time, and even though there as no street fair and not pig, Brandon suddenly began to sign PG with great glee. At first his parents were confused, but then they realized they were standing in the exact spot where the pig had been six weeks earlier! The fair may have been a distant memory to his parents, but it was clearly still vivid to him. Wow! Where his parents impressed! Not only had he remembered a pig seen long ago, but he had also remembered the exact greasy spot by the sidewalk where it had been, showing his parents just how smart their baby was!

Brandon’s is only one of many stories showing signs being used to talk about memories. Do you have examples of your own? I’d love to hear them! Send them along to me via email at info@babysigns.com (putting Baby Signs in the subject line to make sure I get it.) and maybe they’ll make it into a future posting right here!

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!

Pretending is More Than Just Child’s Play

There’s a common theme to a great majority of popular kids’ toys: Pretending. Whether it’s a baby doll, a tea party, a toy fire engine, or a make-believe cell phone, the goal is pretending. In fact, what researchers call “fantasy play” is so common among the 1- to 6-year-old crowd that most adults just take it for granted without appreciating what an impressive developmental milestone it represents.

What’s the big deal? If you think about it, feeding pretend milk to a pretend baby requires a child to insert an extra mental step in comparison to an equivalent real situation where she is drinking milk herself or tipping her bottle up for Mom to have a sip. In the case of the baby doll she is also keeping in mind that the baby doll represents or symbolizes a real baby and the pretend milk represents or symbolizes real milk. How do we know she’s pretending? She’s clearly not surprised or upset when no milk comes out and the “baby” simply continues to lie there!

This same kind of mental gymnastics—which researchers refer to as the ability to use and manipulate mental symbols—is involved when children pretend to cook, have a tea party, crash toy cars, or fly toy planes. And development of this skill doesn’t stop here. As toddlers turn into preschoolers, their pretend play not only gets more elaborate but also gets more “abstract.” No longer is it necessary to play with something that closely resembles the real object (as a doll does a baby or a toy car does a real car); the preschooler now has the mental flexibility to pretend that a soft pillow is a baby that can be rocked or a block is a car that can go “vroom vroom.” In fact, development of the ability to pretend (or imagine) continues to get even more abstract until no physical object is needed at all—the arms can rock a totally imaginary doll!

So, the next time your child begins some kind of pretend scenario, appreciate it for what it is: a sign that the brain in that adorable little head is evolving in a wonderful direction, that is, toward increasingly sophisticated imagination—which, after all, is an important foundation of the valuable talent we call creativity.

Our Study Still Stands Tall!

One of our Baby Signs® Instructors called my attention last week to an article by a Speech Pathologist who was questioning our research findings that signing helps children learn to talk. She was basing her criticism on a study by researchers in England who claimed to be replicating our study but finding no positive effects when the verbal development of their signing group of babies was compared to that of their control group of babies.

Whenever such criticisms arise, the first thing I do is get my hands on the supposedly contradictory study and read it carefully. So that’s what I did, and just as I suspected, the authors didn’t have a leg to stand on! Let me outline a few of the more blatant differences between their study and ours, differences that explain why they didn’t find the language advantages we did. This post will be longer and a bit more “academic” than usual, but please bear with me. We want every parent who’s signing with a child or even contemplating doing so, to share the unwavering confidence we have in our own research.

Issue: Sample Size. The smaller the sample size (number of subjects within two groups), the harder it is to demonstrate a statistically significant difference between them, especially when the behavior in question varies dramatically from subject to subject as early language development does.
• Our study--Goodwyn, Acredolo, & Brown (2000): 32 in the Signing Group, 39 in the Control Group.
• English study: 10 in each Signing Group, 10 in the Control Group.
Conclusion: Goodwyn et al. was more likely to detect a facilitative effect, the English study more likely to miss a facilitative effect genuinely there.

Issue. Length of the study. Language development in its early stages is notoriously variable across children. The longer data collection continues, the more likely that trends will be visible.
• English study: Ceased data collection at 20 months.
• Goodwyn, Acredolo, & Brown (2000): Continued data collection well past 20 months (i.e., 24, 30, and 36 months).
Conclusion: Goodwyn et al. (2000) was more likely to discover a meaningful trend in the direction of a facilitative effect of signing.

Issue: Number of Signs Learned. To determine whether signing by infants facilitates learning to talk, the “signing group” has to have actually learned a meaningful number of signs. The larger the number of signs learned, the better equipped the study is to determine if signing makes a difference. If a baby learns only a handful of signs, one wouldn’t expect much of an effect on learning to talk.
• Goodwyn, Acredolo, & Brown (2000): Average number of signs learned = 20.3 (Range 9-61 signs)
• English study: Highest average number of signs learned across ages was 8.67 (Range 2-17 signs)
Conclusion: Goodwyn et al. was in a better position to test the effect of signing because the subjects in their study actually learned many more signs.

Why does the number of signs a baby uses matter to verbal development?

• Signs pull language from adults. Babies learn words from listening to adults. When a baby uses a sign (e.g., BIRD) upon seeing a bird, the adult responds with lots of words (“Yes! That’s a birdie! We call that a robin. See, there’s another bird. Oh, the bird flew away.”) The more signs a baby knows, the more likely this is to happen.

• Signs enable babies to pick the topic. Again, babies learn words from listening to adults. When a baby uses a sign, it starts a conversation about something the baby is interested in, thereby making it more likely the baby will listen to and learn from what the adult says. The more sign a baby knows, the more likely this is to happen.

• Signing excites babies about communicating and motivates them to move on to an even better system--words. The more signs a baby is able to use successfully to communicate, the more motivated he/she is to get better at communicating—that is, to move on to words.

• Signs increase a baby’s interest in books. Babies learn new vocabulary from reading books with parents. Because signs enable babies to be active participants in book-reading (naming pictures with signs), babies are drawn more strongly to books, thereby exposing them to more new vocabulary items. The more signs a baby knows, the more likely this is to happen.

Issue: Why did children in Goodwyn et al. (2000) learn more signs?

• Instructions to Parents. The instructions to parents clearly can affect the number of signs learned.
o Goodwyn, Acredolo, & Brown (2000): Parents were encouraged to choose whatever signs they thought their child might be interested in learning and to add new signs at any time. This freedom addresses the fact that not all babies are interested in the same things.
o Kirk et al. (2013): Parents were told to stick to a specific set of first 10, and then 20 signs no matter what their child’s interests.

• Amount of modeling. The more a sign is modeled by the parent, the more likely it is to be learned by the child.
o Kirk et al. (2013): Data indicate that parents on average modeled a sign “a few times a week to once a day.” This isn’t nearly enough!
o Goodwyn et al. (2000): Modelling rate was not reported. However, the likelihood that parents would, in fact, model signs was increased by the fact that they were given specific toys and books depicting objects represented by signs.

Given all the points I’ve outlined, I hope you can see why we disagree so strongly that this new study somehow negates our findings of a facilitative effect of signing on verbal development. And even if you hadn’t read this posting, all you would have had to do is talk to parents of preschoolers who used signs as babies to feel confident that signing is not just “okay,” but actually really good for language development.
