Nonlinearity in the perception of form [PDF]
Perception & Psychophysics, 1985 ofcontrast, rather than to contrast itself. This finding mayleadto a new understanding ofthe way in whichthe visualsystem segregates objects from their backgrounds.Visual patterns were created on the face ofa cathoderay tube monitor (Tektronix608) with an electronic visualdisplay instrument (Milkmanet al., 1980) underthe control of a microcomputer ...

Form and Function in Information for Visual Perception [PDF]
i-Perception, 2021 Visual perception involves spatially and temporally coordinated variations in diverse physical systems: environmental surfaces and symbols, optical images, electro-chemical activity in neural networks, muscles, and bodily movements—each with a distinctly different material structure and energy. The fundamental problem in the theory of perception is to

The effect of inattention on form perception. [PDF]
Journal of Experimental Psychology: Human Perception and Performance, 1981 A state of inattention was achieved by having subjects selectively attend to one of two overlapping novel figures in a series of such overlapping figures. Recognition of form directly afterward was good for figures that had been attended to but was essentially nil for the unattended figures.

Aging and the perception of texture-defined form
Vision Research, 2021 In this study 28 younger and older observers discriminated the global shapes of objects that were defined by differences in texture. The judged stimulus patterns were 3-point micropattern textures. On any given trial, a texture-defined shape (either a vertically- or horizontally-oriented rectangle) was presented; the observers' task was to discriminate

Aging and the Perception of Motion-Defined Form [PDF]
Perception, 2019 A single experiment required 26 younger and older adults to discriminate global shape as defined only by differences in the speed of stimulus element rotation. Detection of the target shape required successful perceptual grouping by common fate. A considerable adverse effect of age was found: In order to perceive the target and discriminate its shape ...

Dynamic form perception in the bending [PDF]
Perception & Psychophysics, 1989 As a white hourglass moves across a black background, the middle appears to lag behind its true position, resulting in the apparent bending of the axis of the hourglass. No such distortion occurs with a black hourglass moving across a white background.

Form perception and attention in pigeons [PDF]
Animal Learning & Behavior, 1997 This report selectively reviews the authors’ research on stimulus control by visual forms. Most studies employed visual search of computer-generated displays, and the main behavioral measure was search reaction time. Pigeons classify simple line forms much as do humans, and there was some evidence for feature extraction, though a search asymmetry probe
