Are you a righty or a lefty? And no, I don’t want to know if you side with the Elephants or Donkeys. I’m talking hands here. As in, which is your dominant one?
I read a short article today in a local paper discussing the findings of a study that indicated that “mixed-handed” or “cross-dominant” kids are more likely to have ADHD, language and learning problems and behavioral issues. This piqued my interest due to the fact that my 13-year-old step-daughter could be classified as mixed-handed and she exhibits none of those symptoms. In fact, she’s about as 180 degrees from that as you could get: almost a straight-A student, prolific writer and all-around great kid. She just writes and eats with her left hand, but uses her right hand for sports, Wii, guitar, etc.
Naturally, I went straight to the source, the online Pediatrics Journal, to read the study for myself and find out why this is, and what the point was. Since I’m not a subscriber, I could only access a small snippet, but what I found was interesting.
Apparently, the point of the study was to find an early way to diagnose kids with potential behavioral issues. According to the study “our objective was to determine whether mixed-handedness, which is associated with atypical cerebral laterality, is associated with language, scholastic, and ADHD symptoms in childhood and adolescence.”
In layman’s terms, I took this to mean that kids who can’t pick a dominant hand must be scatterbrained, and therefore predisposed to acting out and not being able to learn properly. Again, being witness to the exact opposite of this at home, I was skeptical, but realize that this may be the “norm” and that our kid is an exception.
However, I found this line of the study interesting: “Mixed-handed children, relative to right-handed, had approximately a twofold increase in odds of having difficulties with language and scholastic performance at the age of 8 years.” Did they really only compare this to ‘right-handed’ and not ‘left-handed’ kids? We all know right-handed is dominant, but doesn’t this skew the results? Or maybe I’m missing something since I don’t have access to the whole study.
The conclusion (again in layman’s terms) is that if your kid shows signs of mixed-handedness, it might be an early indicator of future problems. Then again, as the original newspaper article I read pointed out, it could be just another detail to make new parents worry about.
So, again I ask, are you a righty, lefty, or do you, too, tend to lean toward the middle? Based on personal experience, do you agree with this study?

I apologize in advance if today’s post is more of a rant than a well-thought-out entry, even despite the fact that I’ve waited approximately 6 hours to cool down.
