Brief Taste Stimuli: Cued and Uncued Magnitude Estimates and Their Reaction Times a

The authors used a closed-flow taste stimulus apparatus, and measured vocal taste magnitude estimation reaction times, using an electret throat microphone, or taste intensity tracking, using a single-axis joystick. For cued judgments, subjects judged and stated the taste intensity as soon as they heard a judgment signal; for uncued, as soon as they thought it appropriate. The uncued experiments confirmed increased taste intensity as stimulus duration increases. However, in the cued magnitude estimation investigations, there were no significant changes in the intensity ratings across the five judgment cue times. The latter was unexpected.
