Amplitude Challenge

Directions

The subject will be asked to compare the intensity of two vibrations. The stimuli will be delivered simultaneously to their index (RIGHT) and middle (LEFT) fingers. Click on the corresponding box of the larger / stronger / more intense vibration 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.
