Abstract
A study of the taste reactions of 414 individuals belonging to the White, Negro and American Indian races shows that races differ in their expressiveness toward the taste of phenyl-thio-carbamide. This difference is so pronounced as to render the actual results of little scientific value. The matter of motivation and rapport is stressed and an appeal is made to psychologists and physicists to secure a more objective method of measuring the reaction of the human subject to PTC.
