味觉敏感性是用各种技术评估的,包括绝对检测和质量识别。对于任何刺激,人们可能会期望敏感性的个体差异反映在所有措施中,但它们往往是令人惊讶的独立。在这里,我们专注于对酸味和咸味的敏感性,部分原因是这些品质的加工相对于其他味道知之甚少。在研究1中,我们测量了柠檬酸(CA)和氯化钠(NaCl)的检测(改良的迫选阶梯法)和识别(改良的Harris-Kalmus程序)的重测信度。尽管良好的重测信度,检测和识别的个体差异弱相关,这表明检测和识别的酸和咸的刺激可能反映了不同的生理过程。在研究2中,受试者的一个子集返回贡献CA和NaCl的完整检测(心理测量)功能。估计从完整的检测功能相关的阶梯和识别阈值,这表明这两个任务可能在一定程度上反映了绝对的敏感性。然而,相对于来自完整检测功能的个体差异范围,阶梯阈值的个体差异范围被系统地压缩。因此,敏感性的个体差异似乎以合法的方式与不同的测试方法相互作用。需要做更多的工作来了解不同的味觉表型如何相互关联。
Taste sensitivity is assessed with various techniques, including absolute detection and quality recognition. For any stimulus, one might expect individual differences in sensitivity to be reflected in all measures, but they are often surprisingly independent. Here, we focus on sensitivity to sour and salty taste, in part because processing of these qualities is poorly understood relative to other tastes. In Study 1, we measured retest reliability for detection (modified, forced-choice staircase method) and recognition (modified Harris–Kalmus procedure) for both citric acid (CA) and sodium chloride (NaCl). Despite good retest reliability, individual differences in detection and recognition were weakly correlated, suggesting that detection and recognition of sour and salty stimuli may reflect different physiological processes. In Study 2, a subset of subjects returned to contribute full detection (psychometric) functions for CA and NaCl. Thresholds estimated from full detection functions correlated with both staircase and recognition thresholds, suggesting that both tasks may reflect absolute sensitivity to some extent. However, the ranges of individual differences were systematically compressed for staircase thresholds relative to those from full detection functions. Thus, individual differences in sensitivity appear to interact with different test methodologies in lawful ways. More work will be required to understand how different taste phenotypes relate to one another.
