Abstract

Introduction

A high level of disgust propensity (the general tendency to respond with the emotion of disgust to any given situation) is associated with an increased sensitivity to bitter taste. The present study examined the relationship between disgust propensity and the sensitivity to bitter aftertaste.

Methods

A total of 200 women rinsed their mouth with concentrated wormwood tea (Artemisia absinthium). The resulting aftertaste was evaluated (intensity of bitterness and disgust) every 15 s for 10 min. A multiple linear regression analysis was calculated to capture the association between aftertaste ratings and affective variables (e.g., disgust propensity, depression symptoms).

Results

Higher disgust propensity was associated with higher initial disgust ratings and faster reduction of disgust over time. Higher depression scores were associated with a slower disgust reduction.

Conclusion

We demonstrated that affective variables predict the temporal course of the wormwood aftertaste response. Having a higher disgust propensity was associated with a shortened disgust recovery.

Implications

A shortened disgust recovery may be adaptive because it enables faster processing of new disgust stimuli.

厌恶倾向与苦味回味反应

高水平的厌恶倾向(对任何特定情况都有厌恶情绪的一般倾向)与对苦味的敏感度增加有关。本研究考察了厌恶倾向与苦味敏感性之间的关系。方法对200名妇女进行浓缩苦艾茶漱口试验。在10分钟内，每隔15秒评估一次最终的余味(苦味和厌恶的强度)。计算多元线性回归分析，以捕获余味评分与情感变量(例如，厌恶倾向，抑郁症状)之间的关联。结果较高的厌恶倾向与较高的初始厌恶评分和随着时间的推移更快地减少厌恶有关。抑郁得分越高，厌恶减轻的速度越慢。结论我们证明了情感变量可以预测艾草回味反应的时间过程。较高的厌恶倾向与较短的厌恶恢复有关。缩短厌恶恢复时间可能是适应性的，因为它可以更快地处理新的厌恶刺激。
