Spatial location control analysis
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.
