      abstract     = {Taste perception, although vital for nutrient sensing, has
                      long been overlooked in sensory assessments. This can, at
                      least in part, be attributed to challenges associated with
                      the handling of liquid, perishable stimuli, but also with
                      scarce efforts to optimize testing procedures to be more
                      time-efficient. We have previously introduced an adaptive,
                      QUEST-based procedure to measure taste sensitivity
                      thresholds that was quicker than other existing approaches,
                      yet similarly reliable. Despite its advantages, the QUEST
                      procedure lacks experimental control of false alarms (i.e.,
                      response bias) and psychometric function slope. Variations
                      of these parameters, however, may also influence the
                      threshold estimate. This raises the question as to whether a
                      procedure that simultaneously assesses threshold,
                      false-alarm rate, and slope might be able to produce
                      threshold estimates with higher repeatability, i.e., smaller
                      variation between repeated measurements. Here, we compared
                      the performance of QUEST with a method that allows
                      measurement of false-alarm rates and slopes, quick Yes–No
                      (qYN), in a test–retest design for citric acid, sodium
                      chloride, quinine hydrochloride, and sucrose recognition
                      thresholds. We used complementary measures of repeatability,
                      namely test–retest correlations and coefficients of
                      repeatability. Both threshold procedures yielded largely
                      overlapping thresholds with good repeatability between
                      measurements. Together the data suggest that participants
                      used a conservative response criterion. Furthermore, we
                      explored the link between taste sensitivity and taste liking
                      or which we found, however, no clear association.},
