Recently in vision science there has been great interest in understanding the perceptual
representations of complex multidimensional stimuli. Therefore, it is becoming very …

Psychometric functions (PFs) quantify how external stimuli affect behavior, and they play an
important role in building models of sensory and cognitive processes. Adaptive stimulus …

Vision researchers are interested in mapping complex physical stimuli to perceptual
dimensions. Such a mapping can be constructed using multidimensional psychophysical …

We propose a new psychometric model for two-dimensional stimuli, such as color
differences, based on parameterizing the threshold of a one-dimensional psychometric …

A subject's response to the strength of a stimulus is described by the psychometric function,
from which summary measures, such as a threshold or a slope, may be derived …

QUEST+ is a Bayesian adaptive psychometric testing method that allows an arbitrary
number of stimulus dimensions, psychometric function parameters, and trial outcomes. It is a …

Psychometric functions typically characterize binary sensory decisions along a single
stimulus dimension. However, real-life sensory tasks vary along a greater variety of …

In this article, we address the problem of measuring and analyzing sensation, the subjective
magnitude of one's experience. We do this in the context of the method of triads: The …

The psychometric function, relating the subject's response to the physical stimulus, is
fundamental to psychophysics. This paper examines various psychometric function topics …

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 …
