We recently reported data showing that, while human olfactory pleasantness is modulated by semantic knowledge of smells, the physicochemical aspects of odorant molecules are prominent determinants of odor hedonic valence, especially in children and seniors, two age groups characterized by either low level of (children) or weak access to (seniors) odor semantic knowledge.1 Here, we present additional data from a human and an animal study, confirming that odorant structure predicts odor pleasantness and suggesting that this influence may be already engraved at receptor level.
我们最近报告的数据表明，虽然人类嗅觉的愉悦感会受到气味语义知识的调节，但气味分子的物理化学方面是气味享乐价的主要决定因素，尤其是在儿童和老年人这两个年龄组中，前者（儿童）气味语义知识水平低，后者（老年人）获取气味语义知识的能力弱。在此，我们展示了来自一项人体研究和一项动物研究的更多数据，证实了气味结构可预测气味的愉悦感，并表明这种影响可能在受体水平就已形成。
