Participants will rate how much pain they experience during several brief thermal stimulations at painful but tolerable temperatures participants pre-approve. During some of the stimuli participants will be in virtual reality, and during some stimuli participants will not be in VR. Sometimes participants will receive two brief stimuli at the same time.
During VR, participants will put their cyberhand into a bowl of animated water and will place virtual objects in the bowl and stir the virtual water. Participants will also receive several brief thermal heat stimulations at a temperature of their choice (sometimes one stimulus, sometimes two simultaneous stimuli). During some of the stimuli participants will be in virtual reality, and some stimuli will not be in VR.

| Virtual Reality distraction | Behavioral | Participants goes into an immersive virtual reality during a brief painful stimulus |
|
| Measure | Description | Time Frame |
|---|---|---|
| worst pain during one stimulus vs during two simultaneous stimuli | graphic rating scale of worst pain intensity measured after one brief thermal pain stimuli, minimum = 0, maximum = 10, and measured again after two simultaenous thermal pain stimuli. In both cases, higher scores mean worse outcome | measured immediately after each pain stimulus |
