Multidimensional Fechnerian Scaling: Probability-Distance Hypothesis

چکیده
This research has been supported by NSF Grant SES-0001925. I am indebted to Hans Colonius for many helpful discussions and for critically reading the earlier version of this paper. I am grateful to Robin Thomas, Jean-Claude Falmagne, and three anonymous reviewers for helpful suggestions. In particular, Falmagne and one reviewer pointed out flaws in my initial treatment of the relationship between the probability-distance hypothesis and the Fechner problem.

Multidimensional Fechnerian Scaling: Pairwise Comparisons, Regular Minimality, and Nonconstant Self-Similarity
Stimuli presented pairwise for same–different judgments belong to two distinct observation areas (different time intervals and/or locations). To reflect this fact the underlying assumptions of multidimensional Fechnerian scaling (MDFS) have to be modified, the most important modification being the inclusion of the requirement that the discrimination probability functions possess regular minima....
متن کاملFechnerian metrics in unidimensional and multidimensional stimulus spaces.
A new theory is proposed for subjective (Fechnerian) distances among stimuli in a continuous stimulus space of arbitrary dimensionality. Each stimulus in such a space is associated with a psychometric function that determines probabilities with which it is discriminated from other stimuli, and a certain measure of its discriminability from its infinitesimally close neighboring stimuli is comput...
متن کاملExpressive faces are remembered with less pictorial fidelity than neutral faces
A repeated finding in the literature of face recognition is that expressive faces are remembered better than neutral faces. However, a better facial-identity recognition may come at a cost of a reduced precision with which the pictorial facial features, irrelevant for identity recognition, are represented in memory. By means of a continuous-report task, we tested this hypothesis by measuring th...
متن کاملPreattentive processing of emotional musical tones: a multidimensional scaling and ERP study
Musical emotion can be conveyed by subtle variations in timbre. Here, we investigated whether the brain is capable to discriminate tones differing in emotional expression by recording event-related potentials (ERPs) in an oddball paradigm under preattentive listening conditions. First, using multidimensional Fechnerian scaling, pairs of violin tones played with a happy or sad intonation were ra...
متن کاملMultidimensional Scaling by Optimizing Goodness of Fit to a Nonmetric Hypothesis
Multidimensional scaling is the problem of representing n objects: geometrically by n points, so that the interpoint distances correspond in some sense to experimental dissimilarities between objects. In just what sense distances and dissimilarities should correspond has been left rather vague in most approaches, thus leaving these approaches logically incomplete. Our fundamental hypothesis is ...
