Asymptotic Learning in Psychophysical
The major types of models that have been proposed to account for the psychophysical data that are obtained when the stimulus differences are small are described briefly. Because it is clear that contingency variables, such as presentation schedules and payoffs, as wet1 as the physical stimuli affect the response probabilities, recent models have included a trial dependent decision mechanism in ...
متن کاملEstimation of Separable Representations in Psychophysical Experiments
Studying how individuals compare two given quantitative stimuli, say d1 and d2, is a fundamental problem. One very common way to address it is through ratio magnitude estimation, that is to ask individuals not to give values to d1 and d2 but rather to give their estimates of the ratio p = d1/d2. Several psychophysical theories (the most known being Stevens’ power-law) claim that this ratio cann...
متن کاملComparing models of contrast gain using psychophysical experiments.
In a wide variety of neural systems, neurons tuned to a primary dimension of interest often have responses that are modulated in a multiplicative manner by other features such as stimulus intensity or contrast. In this methodological study, we present a demonstration that it is possible to use psychophysical experiments to compare competing hypotheses of multiplicative gain modulation in a neur...
متن کاملPsychophysical Detection Testing with Bayesian Active Learning
Psychophysical detection tests are ubiquitous in the study of human sensation and the diagnosis and treatment of virtually all sensory impairments. In many of these settings, the goal is to recover, from a series of binary observations from a human subject, the latent function that describes the discriminability of a sensory stimulus over some relevant domain. The auditory detection test, for e...

Reinforcement learning, belief learning, experiments, probability matching, market price-choice games, computer simulations. This paper explains how simple psychological models of reinforcement and belief learning can be used to explain dynamic patterns of adjustment in economics experiments.
