Day Seventeen

(But really day 18 because I'm waiting on my interview)

This is an interesting book with an article (or chapter) that talks about non-dominant hands compared to using your dominant hand.

What I find interesting is that it explains that when using your dominant hand to do a certain task, and then you go on to use your non-dominant hand for that same task, your ability to complete the task is much better than if you were to use the non-dominant hand (or foot) first, and then the dominant hand. I find that really interesting.

They do lots of experiments on it, like writing, eating, sports, etc. They call this sequential effects after practice.

I think it very intriguing; it has to do with the brain and accessing both part of the brain.

These people did an experiment on four groups of people; 1) children using their left hand only 2) children using their right hand only 3) children using their dominant hand first and then non dominant hand and 4) children using their non dominant hand first and then their dominant hand.

They had them slide a coin across a table to hit a bullseye, and over all the children from group 3 aimed their coin closer to the bullseye over all the other groups.

Kind of interesting, huh. I've read about this a couple of times; athletes will sometimes switch whichever hand they use when swinging a bat or golf club, and it usually only takes them a few months to get used to the left hand because they've already learned it with their right hand. I guess it's much easier to learn if you've already used your right hand for something like that. Who knew.
