Figure 1: Schematic reproduction of a single trial. In total of 80 trials (50% of each stimulus) were presented to the participants in a pseudo-random order. Each trial consisted of the presentation of the word “Ready” for 1000 ms, which was immediately followed by a fixation cross for 1000 ms. After a random period, during which a blank screen was presented, the stimulus was delivered for 400 ms. Next, the phrase “Please Swallow the fluid” was shown on the screen for 5 s. After that, participants were instructed to select a perceived intensity of saltiness between 0 (not detectable) and 4 (very strong) using their figures on the keyboard within 5 s. This procedure was used to confirm that gustatory adaptation did not occur under repetitive presentation of stimuli. Then, a blank screen was presented again for 20 s
