Psychophysical measures attempt to capture and compare subjective experiences objectively. In the chemical senses, these techniques have been instrumental in describing relationships between oral sensation and health risk, but they are often used incorrectly to make group comparisons. This chapter reviews contemporary methods of oral sensory assessment, with particular emphasis on suprathreshold scaling. We believe that these scales presently offer the most realistic picture of oral sensory function, but only when they are used correctly. Using converging methods from psychophysics, anatomy, and genetics, we demonstrate valid uses of modern chemosensory testing in clinical diagnosis and intervention.
心理物理学测量试图客观地捕捉和比较主观体验。在化学感官方面，这些技术有助于描述口腔感觉与健康风险之间的关系，但它们经常被错误地用于进行组间比较。本章回顾了当代口腔感觉评估方法，特别强调阈上标度。我们认为，目前这些标度能最真实地反映口腔感觉功能，但前提是要正确使用。通过结合心理物理学、解剖学和遗传学的方法，我们展示了现代化学感觉测试在临床诊断和干预中的有效应用。
