A fundamental issue in the design and the interpretation of experimental studies of perception relates to the question of whether the participants in these experiments could perform the perceptual task assigned to them using another feature, or cue, than that intended by the experimenter. An approach frequently used by auditory- and…

P. J. Kellman and T. F. Shipley (1992) and P. J. Kellman, P. Garrigan, and T. F. Shipley (2005) suggested that completion of partly occluded objects and illusory objects involve the same or similar mechanisms at critical stages of contour interpolation. B. L. Anderson, M. Singh, and R. W. Fleming and B. L. Anderson (2007) presented a number of…

People are capable of thinking about the future, the past, remote locations, another person's perspective, and counterfactual alternatives. Without denying the uniqueness of each process, it is proposed that they constitute different forms of traversing psychological distance. Psychological distance is egocentric: Its reference point is the self…

F. Attneave (1954) famously suggested that information along visual contours is concentrated in regions of high magnitude of curvature, rather than being distributed uniformly along the contour. Here the authors give a formal derivation of this claim, yielding an exact expression for information, in C. Shannon's (1948) sense, as a function of…

Metacontrast has been the subject of two neural network simulations by Weisstein and Bridgeman. This article compared and elaborated on the two models, corrected flaws not inherent in the models' conceptualizations, and discussed the remaining shortcomings. (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)

The major facts of motion perception are summarized, and three major problems regarding motion perception for moving objects, stable environments, and locomotion in a stable environment are elaborated. A hierarchy of motion types is presented. Evidence that the stimulus for motion is relational is considered. (SLD)

Placing psychology in a biological and physical context, James J. Gibson performed prophetic work on visual motion, inspiring more recent studies on higher order aspects of motion encoding. Although not always fully acknowledged, Gibson's work is very important to the development of perceptual psychology. (SLD)

Reports a series of experiments that give evidence for retention of information about color in very short-term visual memory, commonly termed "iconic memory". (Author)

The theory proposed (recognition-by-components) hypothesizes the perceptual recognition of objects to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components. Experiments on the perception of briefly presented pictures support the theory. (Author/LMO)

The concepts of iconic memory and schematic memory are used to examine two fundamental and related features of the contemporary theory of visual information processing. (Editor)

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. (Author/RK)

An alternative way of attempting to understand visual hemispheric specialization is presented. A theory of certain high-level processing subsystems is formulated in light of an analysis of problems that must be solved by the visual system and the constraints on the solutions to these problems.
