The subject will be asked to compare two vibrations. The stimuli will be delivered sequentially to the index (LEFT) and then middle (RIGHT) finger. Determine which stimulus was larger / stronger / more intense and click on the corresponding box on the computer screen*.

Testing Notes

Response time is not important for this test. If you cannot detect a difference between the two stimuli, make the best guess possible. 

*When hardware response is enabled, you may respond to each question by depressing the corresponding stimulus tip.
