Simultaneous Measurement of Discrimination and Preference
Abstract:
Several taste testing procedures reviewed, all of which provide information about both discrimination and preference. Through use of a "discriminator-nondiscriminator" model, it is possible to assess the efficiency of each procedure in providing estimates of the proportions of the population who truly prefer one product to another, and the proportion unable to tell the difference between products. The procedures examined are found to differ considerably in efficiency. Two procedures, the "repeat pair" and "double pair", are found to have particularly desirable properties.
