Two studies tested the hypothesis that self-reported sense of smell (i.e., metacognitive insight into one’s olfactory ability) predicts disgust sensitivity and disgust reactivity. Consistent with our predictions two studies demonstrated that disgust correlates with self-reported sense of smell. Studies 1 and 2 demonstrated, from an individual difference perspective, that trait-like differences in disgust relate to self-reported sense of smell. Physical forms of disgust (i.e., sexual and pathogen disgust) drove this association. However, the association between self-reported sense of smell and disgust sensitivity is small, suggesting that it is likely not a good proxy for disgust sensitivity. The results of Study 2 extended this finding by demonstrating that individual differences in self-reported sense of smell influence how individuals react to a disgusting olfactory stimulus. Those who reported having a better sense of smell (or better insight into their olfactory ability) found a disgusting smell significantly more noxious as compared to participants reporting having a poor sense of smell (or poor insight into their olfactory ability). The current findings suggest that a one-item measure of self-reported sense of smell may be an effective tool in disgust research.

自我报告的嗅觉可预测厌恶敏感性和厌恶反应性

两项研究检验了以下假设：自我报告的嗅觉（即对一个人的嗅觉能力的元认知洞察力）预示了厌恶敏感性和厌恶反应性。与我们的预测一致，两项研究表明，厌恶感与自我报告的嗅觉有关。研究1和2从个体差异的角度证明，厌恶的特质样差异与自我报告的嗅觉有关。身体上的反感（即性和病原体反感）推动了这种联系。然而，自我报告的嗅觉与厌恶感之间的关联很小，这表明它可能不是厌恶感的良好替代。研究2的结果通过证明个体在自我报告的嗅觉上的差异影响个体对恶心的嗅觉刺激的反应而扩展了这一发现。与嗅觉较差（或嗅觉能力较差）的参与者相比，那些报告称嗅觉更好（或对嗅觉能力更深入的了解）的人发现，恶心的气味明显更具毒性。目前的发现表明，单项测量自我报告的嗅觉可能是厌恶研究的有效工具。与嗅觉较差（或嗅觉能力较差）的参与者相比，那些报告称嗅觉更好（或对嗅觉能力更深入的了解）的人发现，恶心的气味明显更具毒性。目前的发现表明，单项测量自我报告的嗅觉可能是厌恶研究的有效工具。与嗅觉较差（或嗅觉能力较差）的参与者相比，那些报告称嗅觉更好（或对嗅觉能力更深入的了解）的人发现，恶心的气味明显更具毒性。目前的发现表明，单项测量自我报告的嗅觉可能是厌恶研究的有效工具。
