Abstract
There have been used various scales for the sensory evaluation of odor. Psychological distance between each word of the scale has not been investigated in detail, in spite of fundamental matter of measurement. In this paper, firstly, psychological distance evaluated by elder subjects is compared with that by younger subjects. Secondly, psychological distance derived from odor sensory evaluation experiment is made clear by new proposed method which is based on Weber-Fechner's law, and compared with the distance without sniffing odor. Three methods of presentating scale to subjects are also compared; a scale arranged in random, a scale arranged in fixed odor and a scale accompanied with number.
