I'm Crawling on Sunshine...

Thursday, February 4, 2010 at Thursday, February 04, 2010
Er, what? Now before you think I have lost my marbles and forgot that the song is actually "I'm walking on sunshine", rest assured I have not. And you are welcome for now having that song stuck in your head :)

My in-laws just came for a visit and we were discussing the fact that Conner is crawling and cruising his little tushie off. However, he is not walking yet. Now I know he just turned 1, but I am sure every parent is excited around the 1st birthday because that is when you start expecting the little wabbly legs to walk. Or so I am told. In our discussion, my in-laws (Pam and Rich) mentioned that there is a link between intelligence and prolonged crawling. The longer a baby crawls is apparently linked to their intelligence. WHAT? So I had to do some investigating.

I tried to find a lot of information about this topic, but surprisingly found little. It seems that the main person behind this theory is Glenn Doman, a childhood educator that specializes in right-brain training (whatever that means). He is also the author of How To Teach Your Baby To Be Physically Superb. Here is a great quote from the article summarizing what Doman contends:

"...crawling forwards is an essential skill to master. Doman claims that crawling stimulates the brain to develop convergence of vision - and that as a result, people who skip this phase as babies may find it extremely difficult to learn to read and write as children. In addition, children who missed out on crawling may suffer from speech problems, he says - because the same part of the brain controls both functions"

Now I will admit that I have not read his book. I have noticed that he gets a lot of good reviews and has written a number of books. So I can't really critique his book and I am sure it has plenty of scientific research to back up his assertions. But I do take some issue with the claim that learning to read/write and speech are controlled by the same part of the brain. I think that is way way oversimplified. Any of my fellow neuroscientists feel free to chime in if I am wrong.

I have seen babies that crawl "normal", crawl on their butts, or skip crawling all together. And lets not forget that there are some babies that walk by 9 months, and some by 18 months. So to any parent or grandparent out there...did you notice any differences in reading and writing abilities and the length of crawling/onset of walking? I will address this issue more once I have read the book, but for now I thought it would be cool to get some anecdotal input.

Any Baby Can Read?

Tuesday, December 8, 2009 at Tuesday, December 08, 2009
Recently, a friend from high school generously gave me the intro DVD for "Any Baby Can Read". I must confess that I am really excited to see what it is about. And she feels that it was beneficial. But the neuroscientist in me wonders if, well, any baby can, in fact, read? If I haven't already mentioned it, I highly, highly recommend "What's Going on in There? How the Brain and Mind Develop in the First Five Years of Life", by Lise Eliot. Even if you aren't well versed in science jargon, this book is really easy, informative and well researched. The book gives a great overview of the stages of brain development of the visual, auditory, motor and language systems, just to name a few. And after reading this book, I realize that there are stages that babies learn, and there is really no way past those stages. For example, although there is an age range for babies to begin crawling, it is really based on how fast that portion of their motor system develops. Nothing you do can really make them crawl faster. So it is interesting that there is a program which claims it can teach a baby to read, well before most kidlets become "readers".

First let me start by explaining what "Any Baby Can Read" contends their product can do:
"A baby’s brain thrives on stimulation and develops at a phenomenal pace…nearly 90% during the first five years of life! The best and easiest time to learn a language is during the infant and toddler years, when the brain is creating thousands of synapses every second – allowing a child to learn both the written word and spoken word simultaneously, and with much more ease.

Dr. Titzer says the current practice of starting to teach reading skills in school is too late and children benefit greatly from getting a much earlier start since a child basically has only one natural window for learning language -- from about birth to about age four. During this period it is easier for a child to learn any type of language including spoken, receptive, foreign and written language. The earlier the child is taught to read the better they will read and the more likely they will enjoy it.

Studies prove that the earlier a child learns to read, the better they perform in school and later in life. Early readers have more self-esteem and are more likely to stay in school. Meanwhile, a national panel of reading specialists and educators determined that most of the nation’s reading problems could be eliminated if children began reading earlier."

Sounds good, eh? But let us take a look at these claims.

They are correct that when a baby is born, he/she has all of the neurons (cells in the central nervous system) in place, however, synapses (parts of the neuron that communicate to other neurons) are overproduced, called synaptogenesis. The reason for synaptogenesis is that experiences drive changes in the brain. An infants/toddlers brain is like a blank canvas (if you will) and is completely open to new experiences (words, colors, sounds, etc). As the infant/toddler experience their world, their language, their environment, the synapses that are not needed prune back. However, there is absolutely no scientific evidence that kids can learn language and reading simultaneoulsy just because synaptogenesis is occurring.

The next claim that "starting to teach reading skills in school is too late and children benefit greatly from getting a much earlier start since a child basically has only one natural window for learning language" really has no basis. It is true that there is a sensitive developmental window for language (not reading) development. If a child is deprived of language during this period, no matter what you do later, that child will never acquire language. But, reading is not like that. There is no "sensitive" window for reading. If there was, illiterate adults would not be able to learn to read, and they clearly can. I understand that they are saying that these kiddos learn best when they pair language and reading, but this argument really doesn't show that.

This claim really gets me going! They claim that "Studies prove that the earlier a child learns to read, the better they perform in school and later in life". Really? And where exactly are your citations for these studies? Most studies don't show findings so clear, cut and dry. There are a lot of variables to consider when it comes to reading and the effects on later school performance. Do these early readers come from smarter, better educated parents? Do they have a more stable, nurturing environment? Have they been read to from very early in infancy? Do their parents read frequently? Genetics? Environment? You get the picture.

In all honesty, I think what gets me a bit worked up about these products is they play into that natural, and ever-present voice we all have as parents. You know, the one that contanstanly makes you wonder if you are doing all that you can for your kidlet. We all want to have the brightest, smartest, etc. kids because that means they will go on to have productive lives and be contributors to society. And if "Any Baby Can Read" doesn't do what it claims, but at the end of the day encourages quality time spent between parent and child, then to me, that is what it is all about. But I think you can do that for free ;)

So all in all I will give it a try. And if Conner does well, that is great. But I also think that the claims they make are lacking scientific proof (at best) and conflates language acquisition with reading.



Conner's 9 month old check-up

Monday, October 26, 2009 at Monday, October 26, 2009
Today Conner had his 9-month wellness check-up. First, I can't believe he is already 9 months old! Time has flown (well at times it doesn't feel that way). So there we were, Conner, Mommy and Dr. Aggie (see previous post to know why we refer to him as Dr. Aggie :D). Now Dr. Aggie is incredibly nice. He answers my weird off-the-wall questions (and I can definitely bring the weird). But when he starts to question me about Conner's developmental milestones I feel...well for those of you that know me well, I am quite a competitive person. In fact, I have been referred to as "Monica" from Friends (despite the fact that I am nothing like her!). Ahem. Moving along, so he starts to ask if Conner is doing this, that and the other. And I find that for most of the questions my answer is "um, no, not yet". So now I feel like a loser. It must be my fault that Conner isn't pulling himself up to stand using the furniture. No, no, no, Mommy or Daddy have to stand him up, then he can hold himself up using the coffee table. Or that he isn't crawling, cruising, walking, riding a bike, composing music to make Mozart jealous (deep breath!). But I left there thinking that not all babies develop at the same pace and I am not a big ass loser (well at least not in this realm). But I met a good friend for a baby date at Austin's Children's Museum. They have "baby bloomer" day and OMG it was a blast! So there we are, cute babies and all, and over crawls this really beautiful little girl. So the mom and I start talking and when she informs me that her daughter is Conner's age that same feeling of loserhood comes back. Now I know not to compare babies...but damnit I can't help myself! Of course as soon as they started the sing-along and Conner looked at me with this "Mommy I love you and thank you for bringing me here" look (yes people...that was what he was thinking!)...all those feelings of loser-hood went away. Instead I just felt so blessed that I have a healthy little boy who will develop all of these milestones when he is good and ready!

So Moms...did you feel the competitive streak? Did you overcome it?

Learn! Baby! Learn!

My brilliant father-in-law, Rich, sent me a fabulous e-mail asking if there were any books about what babies need to be taught on a month by month, then year by year basis. I have read "What's Going On In There? How the Brain and Mind Develop in the First Five Years of Life" by Lise Eliot (and I highly highly recommend this book, even if you are not of a science persuasion). But this aforementioned book does not really go into great depths about what to teach an infant/toddler, based on what they can developmentally grasp. Instead Dr. Eliot simply, but accurately explains how the brain develops. However, I would love to know what are the best age appropriate toys/activities. I know that anyone can walk into Target and buy a toy based on age. However, I am not convinced that this is necessary. Some of the toys Conner has found to be entertaining (and I am sure educational) have been items from around the house (i.e. that our wooden cooking spoon, when banged against a tupperware container, makes a noise).

I have found a bunch of websites that basically just say talking and reading to your baby is the best thing to do. Does anyone know of a book that has great suggestions for how to stimulate and encourage age appropriate development? Any input would be very much appreciated.

Also, Conner has become a bit bored with his current selection of toys and we need to invest in more. Any suggestions for toys/activities we can buy that an almost 9 month old would love?

And if there are no books...hmm...I have always wanted to write a book...but must must must finish grad school first!

Conner Update

Saturday, October 3, 2009 at Saturday, October 03, 2009
Hi everyone!
Well I thought I would give a bit of an update on Conner. Ladies and gentlemen...(drum roll please)...we have a tooth! And boy oh boy is he not having any fun. Of course I can't blame him. If I had a hard object made up of calcium and phosphorus (and other mineral salts) ramming its way out of my gums, I don't think I would be too hot to trot either. But he is handling it like a little trooper. He has also started "backward" crawling. From what I gather, this precedes crawling forward. He also seems to be very very aware of his environment. He has always been a very curious, observant baby, but now it is as if he is going through a developmental stage and he is becoming more cognitively enhanced. So what that last sentence really means is...his sleeping is interrupted and WE ARE TIRED! But this is just an awesome journey and I love watching him learn and absorb the world!

My next blog entry will be more in line with neuronal/cognitive development. I am going to do an entry on spanking. So tune in...

I like ta move it, move it, he likes ta...MOVE IT!

Wednesday, September 16, 2009 at Wednesday, September 16, 2009
Ok so I really don't have much to offer on this post about any specific research topic. But I was pondering, which I do often, about Conner's development. He is about to turn 8 months old and the little cutie IS NOT CRAWLING YET! And yes, I know, I know...not every baby crawls, and they do it at all different ages. So I guess this got me thinking about other aspects of his development and I thought I would pose some questions for other Mommies out there (or Grandmas, people with an opinion, hell cats and dogs if you please).

1) What age did your baby begin to crawl? Did you do "tummy time" and if so, did they seem to get cranky doing tummy time after a while?

2) When did your baby get teeth? Which teeth came in first? Were there any signs of teething?

3) When was the first word said?

4) Was your baby smaller/cubbier than normal? Did anyone have a smaller baby that has turned into a golly-green-giant of a kid?

Ok if I have missed anything else important that deserves ratiocination, please do tell.

And by the way...babies in blue jeans.EFFING.CUTE.

Hope everyone is doing well and has a fabulous day! Oh and if you could comment here on the blog that would be helpful. Not everyone has a Facebook account and, dear me, I would not want anyone to miss out on all the special little nuggets of input :D

And Mommy…talk BABY to me!

Monday, August 31, 2009 at Monday, August 31, 2009
Anyone that has ever seen a woman interact with a baby can attest to one fact, one certainty in life, if you will…women baby talk to babies. Period. I don’t know what it is, but something just makes us want to raise the pitch of our voice and sound like our tongue was just stuck to the icy flagpole outside. Oh and in case you didn’t catch the title, it is taken from Poison’s “Talk Dirty To Me” song…and yes, you are welcome for it now being stuck in your head! And if you are too young to know who Poison is consider yourself lucky.

But why-oh-why do we talk to babies like that? I mean, babies learn language from those that speak to them and will talking like a baby to your baby impair their language development?

Many, many studies have shown that babies prefer baby talk, aka motherese, parentese or infant-directed talk, to normal plain old adult talk. Baby talk not only has a higher pitch, it also is typically more rhythmic, slower, shorter and more exaggerated than adult talk. Baby talk has also been shown to facilitate the bond between the infant and caregiver and assist in language development and communication between the adult and the baby. So clearly it has been shown to be beneficial.

In 2007, an article published in Brain and Cognition looked at what is going on when an infant hears “baby talk”. The researchers used Electroencephalography (EEG) (which is just a fancy schmancy way of recording electrical activity of the brain when its neurons are firing) and they looked at heart rate using 39, 9-month old infants while they listened to baby talk. The baby talk differed in which emotion it conveyed, i.e. love, surprise, fear, etc. They found that the greatest brain activity was in the frontal lobe (the executive, decision maker, problem-solver) and the highest EEG activity was associated with fear, then love/comfort, and so on. Despite the affect presented (i.e. fear, comfort) all of the infants’ heart rate decelerated. Another interesting finding is that babies who are reported as more temperamental showed greater right frontal lobe activation in response to baby talk expressing fear. Previous research has shown that at rest, babies that exhibit greater fear responses to novel stimuli have greater activity in their right frontal lobe at rest compared to infants that do not exhibit these fearful responses.


http://www.neuroskills.com/tbi/bfrontal.shtml

There is quite a bit of research that shows infants have greater at rest right frontal lobe activity and this will influence the personality of the infant, and into adulthood. This article is good at showing that the content of the talk is also important. If the affect is fear, surprise, or other “negative” emotions, it will affect activity in the frontal lobe differently than affect of comfort, love, etc.

Of course now comes the chicken and the egg aspect. Are fearful, more anxious babies that way because of their brain morphology? Or do their parents create the brain to wire in a way that makes them more anxious? Based on this article, even if you are baby talking, if you are talking in an affect of fear the baby is able to discern that. Or does brain wiring of this nature occur in utero (of course it does!). If you are an overly anxious person, or have encountered a high stress, or fearful situation, your fetus is sure to respond accordingly.

Any thoughts?
