Abstract

Humans are very sensitive to several bitter compounds, although there is great inter-individual variability in the elicited emotional (e.g., disgust) and somatic (e.g., nausea) responses. The variability might be associated with the personality trait “disgust proneness” (DP; general tendency to respond with the emotion of disgust).

This study examined the relationship between the sensitivity to quinine hydrochloride and DP in children (63 boys and 67 girls; mean age?=?8.5?years) and adults (107 men, 95 women; mean age?=?29.4?years). Each participant rated the perceived taste intensity of four gustatory stimuli (sucrose, 0.4?g/ml; sodium chloride, 0.25?g/ml; quinine hydrochloride, 0.006?g/ml; citric acid, 0.3?g/ml) and completed questionnaires that assessed the proneness to experience disgust, anxiety, and depressed mood.

The computed multiple linear regression analyses for the adults showed that DP but no other trait measure was associated with bitter sensitivity. In children, depression proneness and age were predictors of bitter sensitivity.

This study revealed age-dependent correlations between DP and bitter sensitivity.

This finding points to the dynamic features of taste sensitivity (and possibly DP) across the lifespan. Therefore, longitudinal studies are warranted.

儿童和成人盐酸奎宁敏感性与厌恶倾向的关系

人类对几种苦味化合物非常敏感，尽管在引发的情绪(如厌恶)和身体(如恶心)反应中存在很大的个体差异。这种变异可能与人格特质“厌恶倾向”有关(DP;一般倾向于以厌恶的情绪回应)。本研究探讨了儿童盐酸奎宁敏感性与DP的关系(男孩63例，女孩67例;平均年龄8.5岁)和成人(男性107人，女性95人;平均年龄? = 29.4 ?年)。每个参与者对四种味觉刺激(蔗糖，0.4 g/ml;氯化钠，0.25?g/ml;盐酸奎宁，0.006?g/ml;柠檬酸(0.3 g/ml)，并完成评估厌恶、焦虑和抑郁情绪倾向的问卷。计算得到的成虫多重线性回归分析表明，DP与苦味敏感性相关，而其他性状测量与苦味敏感性无关。在儿童中，抑郁倾向和年龄是苦味敏感性的预测因子。这项研究揭示了DP和苦味敏感性之间的年龄相关性。这一发现指出了味觉敏感度(可能还有DP)在整个生命周期中的动态特征。因此，纵向研究是必要的。
