The purpose of this exp. is to find basic criteria for odor classification.
Method1: Multidimensional scaling was applied to 24 stimuli based on Kainoshow's scheme.
Results:(a) The most important criterion of classification by the experts was resinous; burnt vs. sweetness.(b) The results based on direct estimation roughly correspond to those of indirect calculation from semantic differential or Crocker's 4 place digits.
Method2: Two batteries of semantic differential scales which are relevant to odor description were proposed, type one is 25 bipolar and the other is 20 monopolar.
Results:(a) Both of them yielded factors of sensory pleasure, harshness, and vividness.(b) Experts have relatively few reference to pleasantness dimension, which is the most predominant factor for the naïve
Ss.
