Results and Discussion ,

When the sound was the same frequency as the touch, tactile discrimination
performance increased by 12.8%, and when the sound was the opposite frequency as
the touch, tactile discrimination performance decreased by 18.8% in comparison to the
no sound condition (see Figure 3 and Table 1). A two-way ANOVA with auditory
stimulus (none, same frequency, different frequency) and Vibrotactile frequency (100
Hz, 200 Hz) as the two within subject factors revealed a highly significant main effect of
sound (F_bl8 = 21.008, p < 0.001). This main effect was driven both by an increase in
discrimination performance with congruent sounds as compared to the no sound
conditions (t₁₈ = 3.010, p < 0.001) and a decrease in performance with incongruent
sounds as compared to the no sound conditions (he = 4.442, p < 0.001) . Themain
effect of Vibrotactile frequency (F_bl8 = ∙440, p = 0.516) and the sound x tactile
frequency interaction (F_bl8 = 1.434, p = 0.252) were not significant. These results
demonstrate a frequency-specific effect of sound Ontouchperception.
