Control analysis
The spatial location control analysis allowed us to ensure that
participants kept their gaze centered on the center of the screen while
receiving tactile stimulations, and that pupillary measures were not
biased by eye movements. Heatmaps in Figure 2a represent the
spatial distribution of fixations during tactile stimulations. Axes
represent pixels coordinates calculated according to standard
Eyelink®‐1000 1024x768 screen resolution.
