ABSTRACT
From a mathematical modeling viewpoint, there are very close parallels between triad discrimination, preferential choice, and two-alternative identification under certain assumptions concerning the decision rules employed. The purpose of this chapter is to introduce a very general probabilistic model in a computationally simple form that can be used to model results obtained from several different types of psychological tasks. Chapter 11 contains a discussion of a number of probabilistic models of identification. One of these models, based on ordinal decision rules, will be covered in this chapter.
