Discusses the relation between discrimination and identification performance, particularly with regard to experiments with speech and other signals used to draw a distinction between continuous and categorical perception. Offers three main arguments. (Author/RK)

A theory of perception and attention that emphasizes the relational nature of perceptual invariants is developed within the context of auditory pattern research. (Editor)

The objective of this article was to describe and discuss one possible approach to the problem of specifying properties of memory traces. (Author/RK)

Attempts to account for many of the differences between vowels and consonants and between speech and nonspeech, in terms of the range of the contexts in which they are set. Explanations of the different overall levels of discriminability in vowels and consonants in various tasks in terms of their "encodedness" are replaced by a general model…

A previously proposed model for memory based on neurophysiological considerations is reviewed. It is extended by introducing positive feedback of a set of neurons onto itself and allowing the neurons to saturate. The resulting model is analyzed by distinctive features, categorical perception, and as it applies to probability learning. (Editor/RK)

Attempts to apply a chronometric analysis to the tendency of the visual modality to dominate conscious judgments about the presence and location of objects. (Author/RK)

This research assesses whether the presence of noise elements in a visual display affects the detection of target letters at the perceptual or feature extraction level of information processing and whether (a) input or processing channels operate in an independent or interactive fashion and (b) how the spatial relation between signal and noise…

This paper reviewed briefly the major types of masking effects obtained with various methods and the major theories or models that have been proposed to account for these effects, and outlined a three-mechanism model of visual pattern masking based on psychophysical and neurophysiological properties of the visual system.
