One of the fundamental and puzzling questions in vision research is how objects are segmented from their backgrounds and how object formation evolves in time. The recently discovered shine-through effect allows one to study object segmentation and object formation of a masked target depending on the spatiotemporal Gestalt of the masking stimulus (Herzog & Koch, 2001). In the shine-through effec...

In the late 19th century, the Gestalt Psychology rebelled against the popular new science of Psychophysics. The Gestalt revolution used many fascinating visual examples to illustrate that the whole is greater than the sum of all the parts. The physical interpretation of sensations and their quantification by JND’s and Weber fractions were met with innumerable examples in which two identical phy...

Japanese gardens are widely appreciated all over the world for sophisticated, minimal compositions and for the calm yet profound atmosphere which they engender. How are the visual elements of a garden, its rocks, moss, and shrubs, interpreted by the brain, and how do gardens achieve particular expressive and artistic effects? In this paper we suggest how principles of visual psychology can be u...

Introduction: Bender Gestalt test is one of the most famous neuropsychological tests that is simple and it can be used to examine brain injuries. The objective of this research was to investigate the validity, diagnostic strength and the replicability of the Bender VisualMotor Gestalt Test in patients with traumatic brain injury (TBI). Methods: 240 participants were tested in a case-control stu...

‎    The Narumi-Katayama index is the first topological index defined by the product of some graph theoretical quantities. Let G be a simple graph. Narumi-Katayama index of G is defined as the product of the degrees of the vertices of G. In this paper, we define the Narumi-Katayama polynomial of G. Next, we investigate some properties of this polynomial for graphs and then, we obtain ...

In this work we explored phenomenologically the visual complexity of the material attributes on the basis of the contours that define the boundaries of a visual object. The starting point is the rich and pioneering work done by Gestalt psychologists and, more in detail, by Rubin, who first demonstrated that contours contain most of the information related to object perception, like the shape, t...

The practice of professional coaching has grown dramatically over the past 10 to 15 years, with a proliferation of professionals and articles. During this time, there have been only a few coaching articles that draw upon Gestalt principles for their theoretical base. This article focuses on two foundational Gestalt principles, contact and awareness, to demonstrate that Gestalt theory can offer ...

STUDY OBJECTIVE The assessment of clinical probability (as low, moderate, or high) with clinical decision rules has become a cornerstone of diagnostic strategy for patients with suspected pulmonary embolism, but little is known about the use of physician gestalt assessment of clinical probability. We evaluate the performance of gestalt assessment for diagnosing pulmonary embolism. METHODS We ...
