|---|---|---|---|---|
| Session | F(1, 10) = 0.46, p = 0.5 | N/A | F(1, 10) = 0.49, p = 0.5 | N/A |
| Limb | F(1, 10) = 4.68, p = 0.06 | N/A | F(1, 10) = 0.35, p = 0.6 | N/A |
| Condition | F(2, 20) = 3.76, p < 0.05* | Larger amplitudes in normal vision vs. augmented | F(2, 20) = 1.13, p = 0.3 | N/A |
