The study looked at children as they developed from age 1 to 3. As previous research has shown, this study replicated the finding that language skills, particularly vocabulary, helps kids regulate their emotions and behavior. Research has often found that girls are typically more advanced in their language skills, and thus self-regulation skills, at this young age. What was different about this study, however, is that it showed that toddler boys with strong language skills can be as skilled in self-regulation as girls at this age.
What's so important about self-regulation? Well, besides the obvious encounters in daily life (e.g., not running out in the street), self-regulation has been highlighted as one of the key aspects to success in school, career, and life. Ellen Galinsky in her book Mind in the Making, lists focus and self-control as one of the 7 essential skills kids need to learn in order to be successful. She states the following about these crucial skills,
"Focus and self control involve many executive functions of the brain, such as paying attention, remembering the rules, and inhibiting one’s initial response to achieve a larger goal. Scientists call these executive functions because these are the brain functions we use to manage our attention, our emotions, and our behavior in pursuit of our goals. Many scientists now believe that executive functions predict children’s success as well as—if not better than—IQ tests."
So it seems the early development of self-regulation skills can only help our children as they move through life.
Being mom to a 16-month-old boy, made reading this article particularly relevant to me. Even at this young age, I am already beginning to see how language is helping him with self-regulation. He is starting to learn that certain items are off-limits (e.g., trash can, toilet bowl) and when he gets close to them he says "no, no." This "self-talk" is the early stages of this development of self-regulation. He has heard his dad and I say "no" to these items enough that he has begun to internalize it.
Of course, at this age, he is not always successful in staying away from these items, but at least he's learning :) Hopefully, as he learns more and more vocabulary he will be able to say what he needs or wants, as well as continue this internal dialog to help control his actions. I think it is helpful to know that boys really are able to learn language skills to help self-regulation at the same level as girls. Although girls usually have a natural tendency to pick up language earlier, it is important to encourage language skills as much as possible with boys too.
