Day Twenty-Four

(Really day 27)

Here's another article about a test done to see the difference in the non-dominant hand and dominant hands.

They asked medical students to fill out a questionnaire to figure out if the students were right handed or left handed. Then they did a couple of tests to test the ability of their dominant hand vs. their non dominant hand.

The first test was having each student tap their index fingers (at separate times) on a key to see how many times they could tap it in 10 seconds.

The second test, they used a hand-held dynamometer to determine the strength of each hand by having the students squeeze the meter.

The results showed that people's whose dominant hands are their left hands show that they have a higher speed when using their right hand, and have a stronger right hand, than right handed people using their left hand. But what's interesting is that right handed people generally have a stronger/faster dominant hand than those who are left handed.

I think maybe this is because left handed people are so used to using both their hands for tasks that we only have to use our right hand for, so they have strength in both hands, just not as much as right handed people have in just one hand. Very interesting study.
