Phase 3: assessment of attention during VR conditions: does VR drain attentional resources?

APPENDIX
Phase 3 (attention during VR) measured performance on a brief cognitive test designed to quantify how much attention was paid to the odd number taskThe VR treatment order used for the Phase 3 divided attention task was the opposite of the VR treatment order used in Phase 2 (thermal pain stimuli). Since the treatment order of Phase 2 was randomized, VR treatment order was also randomized in Phase 3. It is important to note that there were no thermal pain stimuli during the three odd number tasks.During Phase 3, in addition to measuring participants accuracy on the odd number task, two new original GRS questions were introduced for the first time in the current study, to measure the participants subjective experience about how much VR interfered with their ability to do the odd number task. After completing all three of the two minute odd number sessions, participants were asked to rate/compare how distracting they found “No VR” versus how distracting they found “VR + No real water” versus how distracting they found “VR + Yes real water”. And they were then asked to rate how hard it was to concentrate on the odd numbers during “No VR” versus during “VR + No real water” versus during “VR + Yes real water” (see "Appendix
