| *DHI | 26.7 +/− 6.5 | 0.2 +/− 0.2 | 0.8 +/− 0.9 | M-W: p < 0.001 for VM-M, p = 0.002 for VM-N |
| *MSSQ | 32.2 +/− 4.5 | 10.4 +/− 3.4 | 13.9 +/− 4.9 | t-test: p < 0.001 for VM-M, p = 0.02 for VM-N |
| HIT | 56.7 +/− 2.3 | 53.9 +/− 4.2 | 41.7 +/− 1.2 | t-test: p = 0.6 for VM-M |
| BA | 13.0 +/− 3.2 | 8.0 +/− 1.8 | 5.6 +/− 2.3 | t-test: >0.1 for VM-M and VM-N |
| Age | 36.5 +/− 2.7 | 34.0 +/− 1.1 | 38.1 +/− 3.1 | ANOVA p = 0.39 |

Standard questionnaires were used to quantify the severity of dizziness (DHI22), motion sickness susceptibility (MSSQ23), headache (HIT24), and anxiety (BA25), which are shown as means +/− one SEM for the 12 subjects in each category (as is age). Gender distribution is shown as female:male. Statistical tests are Mann-Whitney (M-W), t-tests, and one-way analysis of variance (ANOVA).
