How Hand Steadiness Can Be Distracted

Published Study on Hand Steadiness
The main idea of the experiment was to see which hand is preferred during certain tasks. In most cases there were more left handed people than right handed (Simon, 1964, p. 204). The participants were required to draw a straight line with both hands and see what one was straighter. When using their dominant hand they all could make almost perfect straight lines (Simon, 1964, p. 204). When the other hand was being trialed the line was not straight as it was with the dominant hand (Simon, 1964, p. 205). The results were that it was very easy to make a steady straight line with the hand they use all the time rather than using the hand they never use to write with at all (Simon, 1964, p. 205). The observer also took note of who was right handed and who was left handed. The observation ended with more people being right handed but as the experiment continued they recognized left handed people could do other tasks that they were asked with their right hand (Simon, 1964, p. 206). This article mainly concerned steadiness and different interactions with both hands and how they differ. Purpose of Study

The main purpose of this study was to see if the intervention of occupying one hand with a task and watching how it will affect the other hands steadiness. The hand that was being used as an experiment was trying to keep a metal stick from touching the sides of a metal circle for thirty seconds. An intervention was put into play and the participant had to keep the stick inside the hole while tapping multiple fingers with their thumb. This was required to see if this effected how many times the circle got touched after adding an intervention.

Method
In this experiment, we used an impulse response monitor to show if hand movement was different when involving the other hand to complete a different task besides a steady hand. The participant’s dominant hand was taped to the metal...
