Fig. 5
Bar plot for mean PSE values (error vertical line representing 95%CI) rearranged to match VV blocks with VI and VE blocks that correspond to equivalent visual and vestibular stimulations, respectively (panel a: VI-Up, VV-Down and VE-Down blocks; panel b: VI-Down, VV-Up and VE-Up blocks). Planned t-tests highlighted how PSEs from VV blocks fall in between values from unisensory conditions with correspondent visual and vestibular stimulations (**, p < 0.010. ***, p < 0.001). Continuous arrows represent the C direction in the same format as Fig. 2. Dashed arrows represent the visual C direction resulting from chair motion. Panels c and d represent the psychometric functions defined from estimated PSE and JND (error horizontal line representing 95%CI on the PSEs) with the same rearrangement of panels a and b, respectively. Same color code as Fig. 3.
