Abstract

Individual experience is subjective: We can describe experiences, but we cannot share them directly. Thus, many investigators favour threshold measures of experience , while suprathreshold methods are met with scepticism. We believe that suprathreshold measures are useful, as they reveal group differences in sensation that cannot be observed with thresholds. These differences, however, are distorted when scales are used incorrectly. Of particular interest, oral sensory intensity predicts long-term health outcomes ; these findings are validated by robust differences in oral anatomy, suggesting that valid suprathreshold comparisons convey accurate and meaningful differences in experience
