Distances needed for participants to perceive they had moved to the position of each of three previously seen target distances (Move-to-Target task, left panel) and the distance set as matching their previously experienced travel to those target distances (Adjust-Target task, right panel) for in-lab (purple and yellow bars) and in-pool (green and blue bars) for supine (purple and green bars) and upright (yellow and blue bars) postures. Targets were simulated at 8, 12 and 16 m from the participant (see Fig. 8a). Boxes represent ±1 interquartile range, whiskers ±1.5 interquartile range, lines are medians and “x” are means. A repeated measures ANOVA yielded significant effects for the factors task, task × distance and distance × posture.
