Appendix 3—figure 1. Blinding efficacy (Exp. II).

(A) An auditory masking stimulus significantly decreased participants’ ability to determine whether they had received ultrasonic stimulation. (B) However, when masked stimulation was applied over different sites, participants still rated these stimuli as sounding less similar than stimulation applied over the same site. Bars represent means across participants, error bars represent the standard error, and points represent individual participants. ***p<0.001.
