Like many people, I’ve put in a good amount of time watching internet clips of cute babies/kittens/puppies/parrots/etc on YouTube. While the videos range from ridiculous to fairly amusing, I recently found myself totally captivated by a video featuring a baby who uses sign language.
What at first glance appeared to be yet another cute baby making faces video quickly took on an added dimension. I noticed this baby doing something with her hands. Over the next few minutes I came close to rubbing a bald spot on my chin because of my amazement.
Watch the video, I highly recommend turning your sound on.
The child in the video is a one year old girl and her parents started training her using sign language at an early age. The fascinating part is that, although she was able to say a few words, a good portion of the words that she was able to sign she wasn’t able to say.
In fact, according to the norms of child development, babies usually aren’t able to ask for foods by name until they’re 18-24 months old, but she does this in the video with signs. At a year old they have a vocabulary that can be counted on both hands. This is not for lack of cognitive ability.
It turns out that as children grow, their hand-eye coordination develops much more quickly and at an earlier age than their speech abilities. While there are many muscles in the human hand and arm, there are many more in the face and throat that are required for making intelligible sounds.
So because they’re able to exhibit comprehension at 12 months old, they’re also able to mimic giving commands or requests at 12 months old. While their vocal ability takes longer to develop, babies, it seems,have the cognitive and physical ability to communicate by making signs or approximated signs.
