Perceptual Organization and the Development of Insight

Archives of General Psychiatry, 1963
Clinical evaluation of mental patients is largely based on their verbalizations. Although some patients, while very sick, may develop a pseudoinsight or speak pseudorationally, we do not ordinarily see the converse of this: patients who are clinically well but cannot express themselves reasonably.

Perceptual organization in Alzhiemer's disease.

Psychology and Aging, 1994
The ability of 16 AD patients and 16 age-matched control Ss to discriminate degraded forms was compared. Also examined were the effects of aging on perceptual organization by comparison of performance of normal Ss ranging in age from 20 to 86 years. Ss discriminated 2 forms, a circle and a square, each composed of randomly distributed dots concurrently

Achievement as a Criterion in Perceptual Organization

The American Journal of Psychology, 1968
Brunswick has defined the criterion that S uses in perceptual judgments as 'achievement': S judges, classifies, estimates, etc., in such a way to maximize his achievement.' Unfortunately, this definition has a certain amount of ambiguity. Achievement can be accuracy in those cases where S is given a judgmental task.

Perceptual organization of occluding contours

[1990] Proceedings Third International Conference on Computer Vision, 2002
The mechanics of occlusion of one surface by another are described by a set of integer linear constraints. These constraints insure that the output of a contour grouping process is physically valid and consistent with the image evidence. Among the many feasible solutions, the most compelling is the solution which best explains the presence and form of ...

Learning Perceptual Organization in Infancy

Psychological Science, 2005
It has been demonstrated that older infants (6- to 7-month-olds), but not younger infants (3- to 4-month-olds), use form similarity to organize stimuli consisting of X and O elements. We investigated whether utilization of form similarity is governed by maturation or experience by contrasting how infants perform when familiarized with a single ...

Perceptual organization as nested control

Biological Cybernetics, 1984
It is argued here that perceptual organization is the structuring of environmental stimuli into nested structures of control. This view is derived from our proposal that the perceptual system forces any stimulus set to have the algebraic structure G of a machine, and that G is given a specific factorization sequence, G = G1 X G2 X ...

Perceptual Organization

Abstract Perceptual organization concerns the organization of people’s perception into meaningful, structured entities—often wholes containing parts, with specific interrelationships among the parts as well as specific relationships between the parts and the wholes.

Perceptual organization based on temporal dynamics

IJCNN'99. International Joint Conference on Neural Networks. Proceedings (Cat. No.99CH36339), 2003
This paper presents a computational model for perceptual organization. A figure-ground segregation network is proposed based on a novel boundary pair representation. The system solves the figure-ground segregation problem through temporal evolution. Gestalt-like grouping rules are incorporated by modulating connections, which determines the temporal ...

Perceptual Organization and White's Illusion

Perception, 2003
The apparent lightness of a surface can be strongly modulated by the spatial context in which it is embedded. Early theories of such context dependence emphasized the role of low-level mechanisms that sense border contrast, whereas a number of recent authors have emphasized the role of perceptual organization in determining perceived lightness.

Perceptual Organization and the Judgment of Brightness

Science, 1993
The perceived brightness of a gray patch depends on the surrounding context. For example, a medium-gray patch appears darker when placed on a bright background and brighter when placed on a dark background. Models to explain these effects are usually based on simple low-level mechanisms.
