Journal Article: The relative power of difference testing methods in sensory evaluation (1990)

Abstract:
In an experiment in which people are instructed to make difference or similarity judgments, they will make decisions on the basis of information obtained from the objects being tested, such as foods or beverages, and a decision rule based on the instructions given to them by the experimenter. In addition to these factors, the outcome of such an experiment may be affected by response bias (a tendency to respond in a particular way irrespective of the sensory information), adoption of strategies to “get the right answer,” adaptation (a physiological effect), and attention (selecting particular attributes on which to base a decision and neglecting or ignoring others).
