Journal Article: Kinetic models of sweet taste (1992)

Abstract: New and old models in analytical pharmacology may be useful in the study of chemosensory phenomena. The mechanism by which sweet-tasting molecules exert their effect on taste neurons is similar to the mechanism by which beta-adrenergic agonists affect cardiac stimulation. A brief account of historical contributions to the development of pharmacokinetic models is...

Journal Article: Modeling similarity and identification when there are momentary fluctuations in psychological magnitudes (1992)

Abstract: To discover the hidden structure in what we observe is a source of great enjoyment and a worthy goal for scientists to achieve. This structure is often revealed by successively employing models of increasing elegance and generality. The physical attributes of any set of objects will never occur at exactly the same value....

Journal Article: A general probabilistic model for triad discrimination, preferential choice, and two-alternative identification (1992)

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...

Journal Article: Molecular models based on competitive and non-competitive agonism (1991)

Abstract: Agonists in mixtures may bind to a common receptor or to independent receptors. Signal generation may also depend on a transducer, such as a G protein. Interactions among agonists, receptors and transducers lead to changes in the activity of effectors, such as adenylyl cyclase, resulting in signals which affect behavior. In this paper,...

Journal Article: Modeling the sweet taste of mixtures (1991)

Abstract: Perceptions resulting from the simulation of the chemical senses presumably begin with molecular interactions between chemicals and some form of transduction mechanism. This mechanism may involve receptors and specific transducer proteins, such as G proteins. Many mechanisms can be proposed to describe the initial and later events in the chain from chemosensory stimulation...

Journal Article: A simple multivariate probabilistic model for preferential and triadic choices (1991)

Abstract: Multidimensional probabilistic models of behavior following similarity and choice judgments have proven to be useful in representing multidimensional percepts in Euclidean and non-Euclidean spaces. With few exceptions, these models are generally computationally intense because they often require numerical work with multiple integrals. This paper focuses attention on a particularly general triad and preferential...

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,...
