This study measures how many words people can recall. Some words are studied/heard/learned while in immersive Virtual Reality, and some are studied/heard/learned while in a plausible control distraction.
In this Study (n=20), participants recalled word lists during a plausible semi-immersive control condition (passive Apple Vision Pro see-through mode) versus during interactive immersive VR. Participants also later received brief heat pain stimuli during No VR versus immersive VR and provided pain and anxiety and distraction ratings on 0-10 graphic rating scales.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| High Tech virtual reality | Experimental | Participants used their cyberhands to interact with virtual objects while in immersive virtual reality, while they listen to and memorize a list of 15 study words rea to them from the real world. |
|
| Low Tech VR | Sham Comparator | Participants wore an Apple Vision Pro VR goggles that allowed them to see the real world in their VR goggles, via video streaming from cameras mounted on the VR helmet, while memorizing a list of words they heard from the real world. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Immersive Virtual Reality | Behavioral | While wearing an immersive VR helmet, participants grabbed virtual objects andd put them into a bowl of virtual water, while memorizing a list of words from the real world. |
| Measure | Description | Time Frame |
|---|---|---|
| Word Recall accuracy | Number of study words recalled during an immediate recall task | begin 15 seconds after the last word |
| Subjective ratings of Distraction | Participants rated how distracted they were in each treatment condition | Measured immediately after the free recall of each word list. |
| Measure | Description | Time Frame |
|---|---|---|
| During Phase 2, VR pain reduction was measured | graphic ratings of worst pain intensity and other GRS pain ratings during brief thermal stimulation | subjective pain ratings measured immediately after each brief thermal stimulus |

The use of a plausible control condition helped mask the participants.
| Plausible control condition | Behavioral | Participant passively viewed the laboratory room they saw while wearing Apple Vision Pro goggles, while memorizing a list of words read to them from the real world. |
