The report of vestibular sensation, muscle twitch, and tactile stimulation in our experiment to validate the GVS was subliminal. An experimenter applied GVS at 1 Hz, of amplitudes increasing from 0.2 to 3 mA (in both the rightward and leftward directions). Participants scored any sensation they experienced, between 0 and 6 (0 representing no report). The box plots show the across-participant median, the 75% percentile, and range (whiskers) of the participant reports. Participant reports were zero for all the sensations at the amplitude of GVS (0.8 mA) used in our experiment.
