Tactile intensity discrimination in the presence of auditory pure tone (aPT) distractors (6 and 5 subjects for the 100-Hz and 200-Hz tPTs, respectively) (conventions as in Fig. 1). (A) Experimental design. (B,C) Proportions of trials the comparison was judged higher in intensity, averaged across all participants, as a function of the comparison amplitude Ac, tested with 100- (B) and 200-Hz (C) tPT. (D) Sensitivity to differences in intensity was not significantly affected by auditory distractors (repeated-measures ANOVA, F6,24 = 1.7, P = 0.16 and F6,24 = 2.0, P = 0.1, respectively). (E) Similarly, the perceived intensity of the 100- and 200-Hz tPT was not significantly biased by aPT distractors (F6,24 = 0.48, P = 0.82 and F6,24 = 0.97, P = 0.46, respectively).
