QUEST: a Bayesian adaptive psychometric method.
A psychometric function describes the relation between some physical measure of a stimulus and the probability of a particular psychophysical response. The physical measure is usually stimulus strength, and the response is "yes" (in a yes/no experiment) or "correct" (in a forced-choice experiment). More generally, there are several possible responses, each with its own psychometric function (e....
متن کاملBayesian adaptive estimation of psychometric slope and threshold
We introduce a new Bayesian adaptive method for acquisition of both threshold and slope of the psychometric function. The method updates posterior probabilities in the two-dimensional parameter space of psychometric functions and makes predictions based on the expected mean threshold and slope values. On each trial it sets the stimulus intensity that maximizes the expected information to be gai...
متن کاملA exible Bayesian method for adaptive measurement in psychophysics
In psychophysical experiments time and the limited goodwill of participants is usually a major constraint. This has been the main motivation behind the early development of adaptive methods for the measurements of psychometric thresholds. More recently methods have been developed to measure whole psychometric functions in an adaptive way. Here we describe a Bayesian method to measure adaptively...
متن کاملBayesian inference for psychometric functions.
In psychophysical studies, the psychometric function is used to model the relation between physical stimulus intensity and the observer's ability to detect or discriminate between stimuli of different intensities. In this study, we propose the use of Bayesian inference to extract the information contained in experimental data to estimate the parameters of psychometric functions. Because Bayesia...
متن کاملBayesian Adaptive Estimation of Psychometric Slope and Threshold with Differential Evolution
The adaptive experimentation methodology has been adopted in visual psychophysical modeling in the pursuit of efficiency in experimental time and cost. The standard scheme only optimizes one design in each experimental stage, although simultaneous optimization of multiple designs per stage can be beneficial, but difficult to implement because of a surge in computation. In this study, we incorpo...
