The Psychophysics of Price: A Critique of the Weber

psychophysical judgment and measurement carterette edward

Personality psychologists often ask people to rate their own feelings and behaviors. The report ends with a discussion of motivational effects of a more intrinsic form that are being studied as part of work on perceptual motor skills, including response integration, looking behavior, and vehicle guidance. Thus, if the former structure is replaced by the latter, then Eq. In our notation Weber's law is equivalent to the assertion Pcx,cy ~ Px, y for any positive real number c and all x, y. The report examines the historical background of the role of motivational concepts as determinants of perceptual events.

Physiological studies conducted in the 1960s and 1970s summarized in Luce, 1986, 1993 of the temporal coding of simple tones by individual fibers of the eighth nerve revealed that histograms of interpulse times were roughly exponential in their gross shape. Topics are covered in comprehensive surveys in which fundamental facts and concepts are presented, and important leads to. Conjoint Structures with Additive Representations Let us return to the simpler case of a weak order. The assigned ratings are viewed as constituting a psychophysical law relating measures of the stimulus to subjective contributions. Transformations that render curves parallel.

Luce summarize the literature of behavioral decision making that attempts to address these issues. By the Narens-Alper theorem, we may assume that gt has been chosen so that the translations are multiplication by positive constants. This observable distinction generalizes to more than two factors. This illustrates an important point--namely, that invariance under automorphisms is a necessary condition for a concept to be formulated in terms of the primitives of a system, but it is by no means a sufficient condition.

At this juncture, he proposes a method of analysis that focuses on the significance of status and lifestyle in social relations that can help explain how the consumer marketplace is shaped. Green, 1977, Journal of the Acoustical Society of America, 6I, p. Mass, charge, and several other basic physical quantities can be measured in this fashion. The attribute in question, ~, is an ordering ofA x U, and we suppose it is a weak order. Journal of Experimental Psychology, 72, 94-104. C, substantial empirical evidence exists for believing that many psychological attributes are approximately power functions of the corresponding physical measures of intensity.

Reprinted with minor modifications in W. This article reports the adaptation of an experimental technique for establishing response scales for product classes. Ordinal Representations One major feature of measurement in the physical sciences and, to a lesser degree, in the behavioral and social sciences is the convenience of representing the order information numerically. Heaviside Mathematics is a tool for thought. American Economic Review, 73, 596-605. These models and experiments focus on what seem the simplest possible questions, and yet complexity arises because of two subject-controlled tradeoffs: that between errors of commission and errors of omission and that between overall error rate and response times. Choice, similarity, and the context theory of classification.

The bow and sequential effects in absolute identification. To do so, we idealize response behavior, treating it as if responses exhibit no variability. An observer's ability to decide that x is longer, or louder, or of higher pitch, and so on than y is then difficult, and over repeated presentations of x and y, judgments show inconsistency. For the detection task, the fundamental trade-off involves two kinds of error: one, an error of omission, arises when an observer fails to recognize the presence of a signal as such; the other, an error of commission, arises when an observer incorrectly reports the presence of the signal. Note that Weber's law itself is special because it is dimensionally invariant, that is, in Eq. Practical implementation of the elimination-by-aspects model is made difficult by the large number of unknown parameters it involves.

Symmetry and Scale Type B. Although applications occur in many disciplines of psychology, the term judgment applies when the investigation involves basic principles assumed to apply across content domains. The axioms of quantity and the theory of measurement. A connected and transitive order is called a weak order. On the other hand, there is no reason why the criterion variance cr2 13 should vary with N.

A second attempt, due to Luce 1990a, and presented as an improved formulation of Luce, 1959b , stated that ratios are captured by translations. We encounter that theory next in the context of identification. Unpublished doctoral dissertation, Ohio State University. Let us treat the simplest case of two independent variables; call their domains A and U. The measurement theory of dense threshold structures. The nonuniqueness is characterized in what are called uniqueness theorems. For a discrimination task to be nontrivial, the members of an offered pair x, y of stimuli must be close in magnitude.
