Boxplots for PSEs (a) and JNDs (b) obtained from all subjects in the two C directions of VI, VE and VV sessions. In panel a, PSE values are referred to an absolute time scale on the left y-axis, and to a relative time scale on the right y-axis. In light blue, red and dark grey data from VI, VE and VV sessions, respectively. Block icons in the same format as Fig. 2. VV blocks are depicted according to their vestibular stimulation. Notches indicate 95%CI for the median. Data marked with red crosses indicate outliers ( > ± 2.7 SD). In the a) panel, the continuous horizontal line represents the 1.400 s duration (i.e. the duration of R stimuli).
