Duration Challenge

Directions

The subject will receive two sequential vibrations - one to each finger - of unequal duration. Determine which of the vibrations lasted longer, and click on the corresponding box on the computer screen*. 

Testing Notes

Response time is not important for this test. It may feel as though the two vibrations are of equal duration. If you cannot detect a difference in duration, make the best guess possible. 

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