(A & B) Four graphs showing the results of individual participants in McFadden et al.’s [[19]] magnitude estimation study on suprathreshold salty and sweet solutions made in the absence ( white circles ) versus presence ( black circles ) of background noise. Visual inspection of these graphs clearly reveals that the presence of the background noise had no obvious impact on this participant’s sensory-discriminative ratings of the perceived intensity of the tastant.
