Special Issue Quantitative Approaches in Gestalt Perception

Michael Herzog

Elsevier2016

Electrophysiological correlates of backward masking in students scoring high in cognitive disorganization

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Guillaume Sierro, Christine Mohr

Association for Research in Vision and Ophthalmology2016

The effects of spatial attention on temporal integration

Michael Herzog, Marc Michael Lauffs

Feature fusion reflects temporal integration. Previous studies mostly employed foveal presentations with no attention manipulation. In this study we examined the effects of sustained spatial attention on temporal integration using feature-fusion with perip ...

A New Conceptualization of Human Visual Sensory-Memory

Michael Herzog

Memory is an essential component of cognition and disorders of memory have significant individual and societal costs. The Atkinson-Shiffrin "modal model" forms the foundation of our understanding of human memory. It consists of three stores: Sensory Memory ...

Local versus global and retinotopic versus non-retinotopic motion processing in schizophrenia

Michael Herzog, Maya Roinishvili, Marc Michael Lauffs, Albulena Jashari-Shaqiri

Schizophrenia impairs cognitive function as much as perception. For example, patients perceive global motion in random dot kinematograms less strongly, because the integration of the dots into a single Gestalt is complex (e.g., Chen, Nakayama, Levy, Matthy ...

Mandatory feature integration across retinotopic locations

Michael Herzog, Leila Drissi Daoudi - Kleinbauer

Although visual integration is often thought to be retinotopic, visual features can be integrated across retinotopic locations. For example, when a Vernier is followed by a sequence of flanking lines on either side, a percept of two diverging motion stream ...

How best to unify crowding?

Michael Herzog, Adrien Christophe Doerig, Mattew Pachai

Elsevier2016

What crowds in crowding?

Michael Herzog, Bilge Sayim, Mauro Manassi, Vitaly Chicherov

Association for Research in Vision and Ophthalmology (ARVO)2016

Why our best theories of perception lead to Anti-reductionism

Michael Herzog, Adrien Christophe Doerig

Basic percepts and observation sentences, such as "the voltmeter is at 7A", provide the ground truth for realistic theories. Reduction is the second backbone of these theories linking, for example, neuroscience to physics. First, we will show, by mathemati ...

Tell me about your Ponzo and I will tell you who you are

Michael Herzog, Fred Mast, Aaron Michael Clarke, Lukasz Grzeczkowski

Unlike in cognition, audition and somatosensation, performance between various visual tasks does not correlate. Surprisingly, even tasks that appear similar, like visual acuity and line bisection task do not share much common variance. Similar results were ...

The Honeycomb illusion: Uniform textures not perceived as such

Michael Herzog

We present a series of patterns, in which texture is perceived differently at fixation in comparison to the periphery, such that a physically uniform stimulus yields a nonuniform percept. We call this the Honeycomb illusion, and we discuss it in relation t ...

Backward masking performance in patients with functional psychoses

Michael Herzog, Maya Roinishvili

In visual backward masking, a target is followed by a blank screen (ISI - Inter-stimulus-interval) and, then, a mask which deteriorates target processing. Schizophrenic patients show strong but complex processing deficits in visual masking compared to heal ...

An overview of quantitative approaches in Gestalt perception

Michael Herzog

Gestalt psychology is often criticized as lacking quantitative measurements and precise mathematical models. While this is true of the early Gestalt school, today there are many quantitative approaches in Gestalt perception and the special issue of Vision ...

Visual impairments in schizophrenia

Michael Herzog, Maya Roinishvili, Albulena Jashari-Shaqiri

The obvious symptoms of schizophrenia are hallucinations, delusions, and cognitive dysfunctions. However, schizophrenia patients have many other abnormalities, including visual impairments. Visual paradigms are versatile tools of schizophrenia research bec ...

Neural correlates of visual backward masking: Compensation mechanism in relatives of schizophrenia patients

Michael Herzog, Maya Roinishvili, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Visual backward masking (VBM) is a very sensitive endophenotype of schizophrenia. Masking deficits are highly correlated with reduced EEG amplitudes. In VBM, a target stimulus is followed by a mask, which decreases performance on the target. Here, we inves ...

Endophenotypes of schizophrenia: electrophysiological correlates of first episode patients

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Albulena Jashari-Shaqiri

Schizophrenia is a heterogeneous disorder and among other symptoms, patients have important visual impairments. Visual paradigms are therefore important tools to investigate the mechanisms of schizophrenia. During the last period of the NCCR, we have chara ...

The effects of aging on perception and cognition

Michael Herzog, Aaron Michael Clarke, Daniela Herzig, Albulena Jashari-Shaqiri

The developed world is aging faster than ever before. Even in the absence of neurodegenerative disease, aging affects all kinds of human functions including perception and cognition. In most perceptual studies, one paradigm is tested and it is usually foun ...

Crowding, grouping, and gain control in schizophrenia

Michael Herzog, Maya Roinishvili, Albulena Jashari-Shaqiri

isual paradigms are versatile tools to investigate the pathophysiology of schizophrenia. Contextual modulation refers to a class of paradigms where a target is flanked by neighbouring elements, which either deteriorate or facilitate target perception. It i ...

Targets but not flankers are suppressed in crowding as revealed by EEG frequency tagging

Michael Herzog, Vitaly Chicherov

Perception of a visual target can strongly deteriorate in the presence of flanking elements (crowding). For example, adding lines next to a vernier makes vernier offset discrimination difficult. Crowding is often considered a bottleneck of low-level vision ...
