From this effort she discovered that old standards were in error. People do not perceive or experience stimuli the same. The effort centered on comparing supertaster for PROP (6-n-propylthiouracil) with others. The results suggest that supertasters experience different taste stimuli at higher intensities than normals. This suggest that others should use different yard sticks when comparing subjectively reported experiences. The yard stick should be unrelated to the sensory system being investigated and have measurable physical standards. It is hoped with such efforts that new comparison standards will generate insight into the subjective world of others. Ron Blue http://turn.to/ai --- .
