We predicted participants would be less accurate on the odd number task during VR than during “No VR”, and would be least accurate during VR + Yes real water. A Friedman Test showed a significant main effect of “No VR” versus “VR + No real water” versus “VR + Yes real water” for accuracy (mean number of hits out of 10 possible hits) on the odd number task, χ2 (2) = 17.47, As shown in Table Accuracy on the Odd number “divided attention” task.We predicted participants would be less accurate during VR than during No VR, and would be least accurate during VR + Yes real water. Means (SD).Similarly, participants were 93% accurate during No VR (mean = 9.34 correct, SD = 1.01), and participants made significantly more errors during VR + yes real water, 82% accurate (mean = 8.19, SD = 1.77), Z = 3.91, There was no significant difference in the accuracy on the odd number task during VR + No Real Water (M = 84% correct, mean = 8.35 SD = 1.54) versus VR + Yes real water 82% correct, mean = 8.19, (SD = 1.77), Z = 0.89, Participants’ ratings of how distracting they found VR, and how difficult VR made it to concentrate, are as follows. Participants rated how distracting VR was during the Odd number divided attention task on a zero to 10 scale where 0 = “not distracting at all” and 10 = “extremely distracting” (higher numbers indicate more distraction).We predicted participants would find VR subjectively more distracting than “No VR”, and especially during VR + Yes real water. The results were as follows: On a subjective rating scale from zero to ten (where higher numbers = more distracting), participants rated “VR + No real water” as Mean = 4.94 (SD = 2.02) moderately distracting, and significantly more distracting compared to “no distraction” during “No VR”, Mean = 0.75 (SD = 1.09), Z = 5.89, On a scale from zero to ten, participants rated their difficulty concentrating during “VR + No real water” as “moderately difficult”, Mean = 4.94 (SD = 1.79), which was significantly more difficult compared to “a little difficult” during “No VR”, (Mean = 1.14 (SD = 1.19), Z = 5.80,
