Abstract

Some research groups have studied how to evaluate human olfaction objectively, but there has been no attempt to objectively evaluate the subjectivity evoked by an odor stimulation. We have tried to evaluate the feelings of a subject, namely the subjectivity evoked by odor stimulation. In this study, we have measured the EEG activity of a subject who was stimulated by an odor and we have objectively evaluated the influence of the odor stimulation by chaotic analysis and by frequency analysis. We could obtain the effect of odor stimulation even if the subject did not consciously smell the odor. The results showed that, in the favorite odor stimulation, the chaotic value of the EEG data decreased slowly, but that of the unfavorite odor stimulation dispersed quickly. We could measure the change in the feelings of the subject by odor stimulation, and we could predict the feelings of the subject by using several, more suitable explanatory variables selected from the physiological information.

利用生理信息预测受试者在气味刺激下的感觉

一些研究小组已经研究了如何客观地评价人类的嗅觉，但还没有尝试客观地评价由气味刺激引起的主观性。我们试图评估一个主体的感受，即气味刺激所唤起的主观性。在本研究中，我们测量了受气味刺激的受试者的脑电图活动，并通过混沌分析和频率分析客观地评价了气味刺激的影响。即使受试者没有有意识地闻到气味，我们也能获得气味刺激的效果。结果表明，在偏好气味刺激下，脑电数据的混沌值下降缓慢，而不偏好气味刺激下的混沌值分散迅速。我们可以通过气味刺激来测量受试者感觉的变化，我们可以通过从生理信息中选择几个更合适的解释变量来预测受试者的感觉。
