Influences of Fragrance on the Subjective Emotion and Social Cognition

1.香气感知：1）对103名女大学生的4种不同香气的形容词对进行了语义区分法的因子分析。结果表明，香气在3个维度上得到了评价，即愉悦-不愉悦、放松-兴奋和平静-安静。2）香气没有引起任何特定的颜色意象。言语压力和芳香剂：1）吸入主观偏好的芳香剂会使参与者在休息时的焦虑程度比其他没有芳香剂的人更大。2）在言语压力之前，期间和之后连续测量血压和心跳间隔。血压和心率在言语压力下升高。快速傅立叶变换分析表明，心脏交感神经活动增强，心脏副交感神经活动减弱。搏动间期的序贯分析表明，压力反射敏感性在言语过程中没有改变 ...更多信息 应力这消除了血压调节的负反馈使血压升高最小化的可能性。因此，血压的升高是不可避免的，在讲话的压力。吸入偏好的香味不能抑制说话压力下血压的升高。相反，吸入芳香剂抑制了心率的增加，这表明对社会压力的心理和生理反应有缓解作用。对人际距离和香味的认知：在两个陌生女性面对面30 cm和260 cm的实验环境中，香味偏好的存在会增加被试的人际距离感，并使被试感觉到与没有香味的情境相比，所提议的情境更令人愉快，更容易管理。偏好的香味改善了伴随社会交往的情绪和生理压力。少

1. Perception of Fragrances :1) Factorial analysis of the adjective pairs scored by a semantic differentiation method was performed on 4 different fragrances in 103 female college students. The result showed that fragrances were evaluated by 3 dimensions, i.e. pleasant-unpleasant, relaxing-excitatory, and loud-quiet.2) Fragrances did not provoke any specific color images.2. Speech Stress and Fragrances :1) Inhaling fragrances of subjective preference caused a greater decrease in anxiety in participants at rest than the rest without fragrances.2) Blood pressure and interbeat intervals were continuously measured before, during and after the speech stress. Blood pressure and heart rate increased during speech stress. A fast Fourier's transform analysis showed that the activity of cardiac sympathetic nerves was increased and that of the cardiac parasympathetic nerves was decreased. A sequential analysis of interbeat intervals showed that baroreflex sensitivity was not changed during speech … More stress. This eliminates a possibility that the negative feedback of blood pressure regulation minimizes the increase in blood pressure. Therefore, the increase in blood pressure is not avoidable during speech stress. Inhaling fragrances of preference failed to inhibit the increase in blood pressure during speech stress. Inhaling fragrances, in contrast, inhibited the increase in heart rate, suggesting a mitigative effect on the mental and physiological responses to the social stress.3. Cognition of Interpersonal Distance and Fragrances : In the experimental settings where 2 unknown females facing at 30 cm and 260 cm distance make discussion each other, the existence of fragrance of preference tended to increase the perceived interpersonal distance and to cause a feeling that the proposed situation was more pleasant and easy to manage in comparison with situations without fragrances.The results of this study show that fragrances of preference ameliorate the emotional and physiological stress accompanied by the social communication.
