本文介绍了一种两种选择，被迫选择，楼梯，跟踪程序，称为味觉检测阈值（TDT）测试，提供了一个可靠的措施甜，咸，和鲜味味觉检测阈值从童年到成年。该方法的优点包括对儿童和成人相同的程序，从而允许确定与年龄相关的和个体的味觉差异，如果有的话，以及可以在相对短的时间内完成的任务，不依赖于持续的注意力或需要记忆，控制主观反应偏差，并最大限度地减少语言发展的影响。禁食1小时后，向参与者提供成对的溶液;在每一对中，一种溶液是水，另一种溶液含有不同浓度的促味剂。使用全口品尝方法，参与者品尝每种溶液（不吞咽，在品尝之间冲洗），然后指向具有味道或味道不同于水的溶液。在随后的一对刺激的浓度增加后，一个不正确的反应和减少后，两个连续的正确反应。当浓度序列改变方向时，发生反转。在发生四次反转后，任务被认为完成，前提是在两次连续反转之间最多有两个稀释步骤，并且一系列反转不形成上升模式。这些额外的标准确保了结果的更大可靠性。然后将味道检测阈值计算为四次反转时浓度的几何平均值。这种方法具有现实世界的相关性，因为它提供了关于味觉感知维度的信息，该维度独立于享乐主义，并且可以随着年龄增长和某些疾病状态而变化，使其成为有价值的心理物理测试。心理物理学工具测量味觉系统的功能，用于研究和健康评估目的。本文描述了一种方法来测量味觉检测阈值，可以确定最低浓度的蔗糖，氯化钠，或谷氨酸盐，可以品尝的个人年轻的6岁。
This paper describes a two-alternative, forced-choice, staircase, tracking procedure, called the Taste Detection Threshold (TDT) test, that provides a reliable measure of sweet, salty, and umami taste detection thresholds from childhood to adulthood. Advantages of the method include procedures that are identical for children and adults, thus allowing the determination of age-related and individual differences in taste perception, if any, and tasks that can be completed in a relatively short time frame, do not rely on continuous attention or require memorization, control for subjective response biases, and minimize the impact of language development. After a 1 h fast, participants are presented with pairs of solutions; in each pair, one solution is water, and the other solution contains varying concentrations of the tastant. Using a whole-mouth tasting method, participants taste each solution (without swallowing and with rinsing between tastings) and then point to the solution with a taste or that tastes different from water. The concentration of the stimulus in the subsequent pair increases after a single incorrect response and decreases after two consecutive correct responses. A reversal occurs when the concentration sequence changes direction. The task is deemed completed after the occurrence of four reversals, provided there are a maximum of two dilution steps between two successive reversals, and the series of reversals do not form an ascending pattern. These additional criteria ensure greater reliability in outcomes. The taste detection threshold is then calculated as the geometric mean of the concentrations at the four reversals. This method has real-world relevance as it provides information on a dimension of taste perception that is independent of hedonics, and that can change with aging and certain disease states, making it a valuable psychophysical test. Psychophysical tools measure the functionality of the taste system for both research and health assessment purposes. This paper describes a method to measure taste detection thresholds that can determine the lowest concentration of sucrose, sodium chloride, or monosodium glutamate that can be tasted by individuals as young as 6 years.
