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.

How Long Does a Sign Last?

One of the questions that our Baby Signs® Instructors hear frequently from parents is how long a sign stays in a baby’s repertoire before the word appears. Of course, the answer is that it varies enormously. If the sign is substituting for a relatively easy word like “ball” or “more,” the word may appear relatively quickly. But even then it depends on the sound that the word starts with—“b” and “m” and “d” sounds being considerably earlier to appear than “j” and “l” and “sh” sounds. Of course, if the word is long and complicated, like “hippopotamus” or “alligator,” the sign is likely to stick around longer.

The answer to how long a sign is used also depends on what strategy a child tends to favor. Our government funded research revealed that some children use signs to free them to work on learning words for other things. For example, a baby who has signs for “dog” and “more” may be content to rely on them and make learning the words for “cat” and “all gone” a higher priority. In other words, these babies tend to hold on to their signs for quite a while, using them to increase the number of things they can talk about.

Other babies seem to use signs to speed up learning the word a sign stands for. In these cases, the word appears relatively quickly. The logic lies in the fact that the more frequently a baby uses a sign, the more often adults respond by saying the word, thereby providing more opportunities for the child to learn it.

So, there are lots of answers to the question of how long signs last—especially given that all these strategies can play a role in a single child’s journey from sign to words!

When to Start Signing

One of the most frequent questions our network of Baby Signs® Instructors hear when they give their Parent Workshops and Sign, Say & Play® classes is “When should we start signing with our baby?” Truth is, there’s no “perfect” time to start signing. Over the years we’ve noticed three different approaches parents take to the issue of when to get started. Each has its own advantages. I will describe all three approaches so you can decide which approach will work best for your family.

Birth – 8 months
Some parents start early – at birth or sometime during the first 8 months. These parents want their babies to get lots of exposure to both signs and words from the very beginning. And they like getting into the habit of signing early on. If you know that you have the patience and the persistence to use signs yourself even though your baby is unlikely to sign back until she’s a bit older, then starting early may be a good choice for you.

8-12 months
Many parents choose to wait until their babies are 8-12 months old to start signing. The advantage of starting during this time period is that babies are closer to the age that they can start using signs themselves (usually around 10-11 months). If you like to see more immediate results, starting during this age range may be best for you.

12+ months
Some parents wait until their babies are 12-18 months old before they start using signs. Even at these later ages most babies still don’t have the words to express all the thoughts they want to share. The advantage of starting during this time is that babies are likely to learn signs more quickly, sometimes within a matter of days. With this approach, however, babies will use their signs for a shorter length of time because signs drop off quickly once babies start using more spoken words.

Finally, is it ever too late to start signing? No, not if a child is still frustrated because he or she can’t say the words needed to communicate important things. In other words, any baby or toddler who shows readiness to communicate, but cannot do so effectively with words, is a candidate for signing, and as a parent, you should not feel that it’s too early or too late to start.

Signs: Here, There, and Everywhere!

Do you remember how, once you were expecting a baby, you began to see pregnant women everywhere? Or, having finally decided to buy a particular car, you started to notice how many like it were already on the road? Where did they all come from? The answer, of course, lies in the heightened awareness that your own situation creates. It’s as though you have special radar unconsciously scanning the environment for the things that are momentarily of special importance to you.

The same thing happens to your baby when she learns a new sign or new word. With a new label at her command, she suddenly sees examples everywhere—even in places that you don’t expect. For example, for 14-monthy-old Eli, the “apple” sign made even a trip to the grocery store a special adventure, what with apples, labels on apple pies and apple juice and even pictures of apples on greeting cards. His mother, like many of us, nad never realized how pervasive apples were in the environment until Eli set about to find them all.

In a similar way, 15-month-old Trina had a love affair with her “bird” sign. Everyone expects to find birds out the window or at the park—but at church? Sure enough, embedded in the stained-glass windows over the altar were not one but two ornamental doves, peace symbols to the congregation but just plain birds to Trina. At least using signs was a quiet way to talk about them!

Like these parents, you’ll find yourself amazed at how vigilant your baby can be. She may be only a baby, but lots of mental activity is happening for her behind the scenes. And each time your baby tells you about something with a sign, she is providing you with a glimpse into all that activity, enabling you to respond appropriately and enthusiastically.

The Infant Toolbox Includes A Moral Compass

Some new research in the area of emotional development has come to my attention and has motivated me to take a detour this week away from my usual topic of signing with babies.

There’s no doubt that by the time they are preschoolers, children understand the difference between virtue and evil deeds—as is evident in their appreciation of Cinderella over the Wicked Stepmother and of Little Red Riding Hood over the Big Bad Wolf. But when does this critical distinction hold sway in the minds of little children? Believe it or not, fascinating new research indicates the seeds of distinguishing “good guys” from “bad guys” are there practically from Day 1! Here is just one example from Professor J. Kiley Hamlin’s lab at the University of British Columbia that demonstrates how we know.

Imagine you’re a 4 month old baby watching the following two events:

(1) A puppet is struggling to open the lid of a hinged box and a second puppet joins the effort, helping get the box open.
(2) The first puppet is once again struggling to open the box, but this time a third puppet jumps on top of the lid, pinning it down, thereby hindering the first puppet’s efforts.

Having seen these little events, you are given a choice of which of two puppets you want to look at and hold—the “helper” or the “hinderer.” Even babies as young as 4.5 months strongly (75%-100% of them) prefer the “Helper,” thereby indicating they took into account the goal of the lst puppet and evaluated the intentions of the 2nd and 3rd: they liked the “Helper” and spurned the “Hinderer.” (And don’t worry, the order of events was varied across children and other scenarios were tested as well.)

This is indeed good news! Why? Because it indicates that humans hit the ground running in terms of preferring helping and cooperation over negative behaviors—and that takes some of the burden off of parents. Rather than having to start from scratch getting their child to understand and prefer helping others, they need only to nurture the seeds that are already there. That’s burden enough!
