Models of Discrimination
Jean‐Claude Falmagne · 2002
Abstract In Chapter 4, we considered a forced-choice paradigm, in which a subject is presented with pairs (a,b) of stimuli (a,b are real numbers, representing the stimulus values on some physical scale). The subject’s task is to select one of the two stimuli as exceeding the other, in terms of some subjective attribute such as loudness or perceived weight, depending on the nature of the stimuli. The basic theoretical notion was a probability Pa,b that the subject chooses a over b.
