Left Handed Research Paper

Once you are finished with the Z, the other person stops the time and writes it down.Then do the same thing again, but with your left hand.Matthew Warren In a world made for right-handed people, life can sometimes be frustrating if you are among the 10% or so who are “adextral” — that is, left-handed or ambidextrous. Brain imaging researchers are systematically excluding adextrals from participating in their studies, according to an analysis of recent research papers published in top neuroimaging journals.

Put the pen on the paper and ask a friend or family member to handle the stopwatch app.

Once they give you the signal to start, write down the alphabet from A to Z as one word as quickly as possible.

All you need is a pen, a few sheets of paper, and the stopwatch app on your smartphone.

Now, place a sheet of paper in front of you and take the pen in your right hand.

While most people identify themselves as left- or right-handers depending on which hand they use when holding a pen during writing, this information might be misleading.

Therefore, psychologists interested in handedness typically use questionnaires that assess multiple types of activities that are performed with the hands.

Thus, drawing two lines simultaneously with both hands results in a longer and straighter line to be drawn by the left hand.

The reason is that moving the nondominant right hand in a left handed person requires the command signals to travers the corpus callosum (the bridge between the two hemispheres) before reaching the left hemisphere for moving the right hand.

After this, do it two more times with the right and the left hand, so that you have completed three runs with each hand.

Now calculate the average times you needed to write the alphabet with your left hand and with your right hand. As you probably expect, left-handers write faster with their left hand, and right-handers faster with their right hand.
