Is Sensitivity Heightened On Your Dominant Side?
Transcript of Is Sensitivity Heightened On Your Dominant Side?
The purpose of this experiment was to evaluate whether a person’s dominant hand is more sensitive than their non-dominant hand. I became interested in this project when I heard that people were debating on which of their hands were more sensitive. The information gained from this project will help others determine if their dominant hand or non-dominant hand is more sensitive.
My hypothesis was that the non-dominant hand would be more sensitive to the temperature of the ice water than the dominant hand. My results do support my hypothesis. I think the tests i did went well and i had no problems, except for the fact that my test subject would sometimes forget what hand he took out of the water first, so we would have to redo the test. Therefore, I had to write a "L" on one hand and a "R" on the other. If i ever do this project again in the future, next time i might use three or four test subjects, so i can have a more clear result.
Is Sensitivity Heightened on Your Dominant Side?
By Abby Sophia
I think the non-dominant hand will be more sensitive because it isn't used as often as the dominant hand, therefore the non-dominant hand will be weaker and won't be able to endure as much cold temperature as the dominant hand.
Independent Variable: Ice water
Dependent Variable: Left-handed and right-handed adult test subjects
Control: Temperature of the ice water
Left-handed and right-handed ADULT test subject
A bowl that is big enough to completely submerge both hands.
Notebook for recording results
Dominant Hand Non-Dominant Hand
1 00:16.46 00:12.34

1. Get a bowl.
2. Fill the bowl with ice water.
3. Ask a test subject to place both hands in the bowl.
4. Instruct the test subject to keep both of their hands in the bowl as long as possible.
5. Tell the test subject to remove one or both hands from the ice water when it becomes to uncomfortable. (Both hands do not have to be removed at the same time.)
6. Start your stopwatch.
7. Record how long the subject is able to keep each hand in the bowl of ice water.
8. Record whether the test subject is right-handed or left-handed.
9. Repeat steps 2-5 for many different right-handed and left-handed test subjects.
10. Analyze your results.
11. Repeat these steps for the next two trials.
