I like to think about things that people don't normally think about to quell my boredom. This particular thought has been bothering me for about a year now...
Which thumb do you use to hit the spacebace? Why? (If you use another finger to hit the spacebar, then choose the thumb that corresponds to the same hand.)
It's a strange question. I was mindlessly looking at my keyboard one day, waiting for my computer to boot, when I noticed that the left edge of my spacebar appeared remarkably more "oily" or "faded" (I don't know how to describe it...kind of like a permanent fingerprint) than the right side. I began to wonder why. I started to pay more attention to how I typed and realized that I use my left thumb to hit the spacebar. I purposefully tried to use my right thumb to make sure I wasn't biased and noticed that it was very hard to do so. In fact, it felt weird and foreign, almost like writing with your nondominant hand. I began to wonder if this phenomenon was attributed to right/left handedness. Funny thing is: I'm not left handed! I began to watch other people as they typed. I noticed that my mother and sister, both right handed, hit the spacebar with their right thumbs. I remembered that I am cross-eye dominant and concluded that I'm probably cross-thumb-typing dominant as well...after all, that wouldn't be much of a surprise.
Obviously, there's no empirical evidence to support my theory. That is why I'd like to take a poll and continue my study from there. Thank you for your participation!
