Sequential Amplitude Challenge

Directions

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.
