Think Fast! Do Lefties Have an Advantage?

4.3 based on 11 ratings

Research Questions:

Do left-handed people react faster than their right-handed counterparts?

Studies indicate that lefties may respond to stimuli faster than righties. This experiment tests this premise with an online “reaction test” to measure reaction time in right-handed and left-handed participants.

Materials:

  • Online reaction test
  • Notebook to record results

Experimental Procedure

  1. Search the internet for an online reaction test.
  2. Have test subject take the reaction test.
  3. Record reaction time.
  4. Repeat test 10 times and take the average of the results.
  5. Repeat the experiment for many left-handed and right-handed people. Make sure each test group contains comparably-aged people and a variety of male and female participants.
  6. Evaluate your results.
