External noise methods and observer models have been widely used to characterize the
intrinsic perceptual limitations of human observers and changes of the perceptual limitations …

A central theoretical assumption in classical psychophysics is that people judge the
intensities of stimulus elements; for example, observers directly report the loudness of a tone …

The authors report 9 new experiments and reanalyze 3 published experiments that
investigate factors affecting the time course of perceptual processing and its effects on …

Discusses the conceptual distinction between conscious and unconscious processes and
considers problems with measuring conscious perceptual experience. Because of …

Several authors have measured the detection ability of human observers for objects in
correlated (nonwhite) noise. These studies have shown that the human observer has …

There are hundreds of indications leading us to conclude that at every moment there is in us
an infinity of perceptions, unaccompanied by awareness or reflection; that is, of alterations in …

In signal detection theory (SDT), responses are governed by perceptual noise and a flexible
decision criterion. Recent criticisms of SDT (see, eg, Balakrishnan, 1999) have identified …

Provides an introduction to the study of perception interrelating classical phenomenological
with newer empirical approaches. Research is discussed in terms of a very general model of …

Abstract PRESENTS A DISCUSSION OF SOME METHODOLOGICAL AND SUBSTANTIVE
ISSUES ASSOCIATED WITH THE USE OF REPORTS IN PERCEPTUAL EXPERIMENTS …

A widely used method for characterizing and comparing inefficiencies in perceptual
processes is the method of equivalent internal noise—the amount of random internal noise …
