Fig. 4: Performance on VR search task.
a Response time as a function of impairment type (box-and-whisker plots, showing median, interquartile range, and range). Black dots indicate individual participants. P values relate to Wilcoxon signed-rank tests (i.e., non-parametric repeated measures t-tests; see body text for statistics). b Scatter plot showing the cumulative distance traveled by each participant’s head and eyes in a single trial, averaged across all trials. Note the separation between each of the three conditions. c Self-reported difficulty ratings. Lines indicate individual participants, with those who rated the Inferior condition as more difficult highlighted by purple solid line. Black bars indicate group-means and 95% confidence intervals (CI95%). d Group-median response times, ±CI95%. These data are the same as those in panel A, but are here broken down into individual six-trial blocks to assess the consistency of the effect, and possible learning or fatigue.
