Introduction
Research has provided evidence for the transfer of single emotions including anger, anxiety and happiness through olfactory chemosignals, yet no work has examined the role of odour function in the aggregation of more complex emotional states or in the emotional contagion process. The aim of the present study was to ascertain whether an individual’s tendency to experience emotional aggregation was affected by objective measures of their olfactory function and subjective self-assessments of the importance of their own olfactory system.
Methods
In this study (N = 70), participant pairs were first assessed individually for olfactory threshold and odour identification, then completed the Importance of Olfaction Questionnaire. Each pair subsequently took part in two collaborative tasks. Individual emotion measures were taken before, during and after the completion of the two tasks.
Results
Multilevel structural equation modelling revealed that individuals’ within-dyad positive emotional agreement scores were associated with both their ‘importance of olfaction’ scores and their olfactory function. A significant association was also found between olfactory performance and the Importance of Olfaction scores.
Conclusions
These results provide evidence that the subjective importance an individual assigns to their sense of smell can predict their susceptibility to experience emotional aggregation during active, collaborative tasks.
Implications
The findings suggest that individuals’ tendency and capability to detect and respond to emotional chemosignals, a process required for olfactory-facilitated emotional contagion, may be affected by individual differences in olfactory function and subjective attitudes toward olfaction.

嗅觉功能与情绪感染的关系
介绍
研究已经为通过嗅觉化学信号传递包括愤怒、焦虑和快乐在内的单一情绪提供了证据，但还没有研究气味功能在更复杂的情绪状态聚合或情绪传染过程中的作用。本研究的目的是确定个体体验情绪聚合的倾向是否受到对其嗅觉功能的客观测量和对自身嗅觉系统重要性的主观自我评估的影响。
方法
在这项研究中（N = 70），首先对参与者进行单独评估嗅觉阈值和气味识别，然后完成嗅觉重要性问卷。每组随后参与两项协作任务。在完成这两项任务之前、期间和之后进行个人情绪测量。
结果
多级结构方程模型显示，个体的二元内积极情绪一致性分数与其“嗅觉重要性”分数和嗅觉功能相关。嗅觉表现和嗅觉重要性评分之间也发现了显着的关联。
结论
这些结果提供的证据表明，个体对其嗅觉的主观重要性可以预测他们在主动的协作任务中经历情绪聚合的敏感性。
影响
研究结果表明，个体检测和响应情绪化学信号的倾向和能力（嗅觉促进情绪传染所需的过程）可能会受到嗅觉功能和对嗅觉的主观态度的个体差异的影响。
