Experiment set-up. Seated in front of a desktop monitor, participants rested their bare left arm on a cushion on the experimenter’s side of a soft curtain, hung from the ceiling to ensure that the participant’s field of view was limited to the screen and did not include the sight of the stimulated limb or the experimenter. On a separate screen, experimenters were guided by a visual meter indicating the brushing speed and remaining trial duration in the touch wanting task.
