Intact and deficient contextual processing in schizophrenia patients

Michael Herzog, Oh-Hyeon Choung, Dario Alejandro Gordillo Lopez

Schizophrenia patients are known to have deficits in contextual vision. However, results are often very mixed. In some paradigms, patients do not take the context into account and, hence, perform more veridically than healthy controls. In other paradigms, ...

Serial dependence does not originate from low-level visual processing

Michael Herzog, Gizay Ceylan, David Pascucci

Perception depends not only on the current sensory input but also on the preceding history of stimuli. In serial dependence (SD), for example, the orientation of a Gabor patch is mistakenly reported as more similar to previous trials than it actually is. T ...

Serial dependence under memory load

Michael Herzog, Ayberk Ozkirli, Gizay Ceylan, David Pascucci, Yury Markov, Natalia Tiurina

Perceptual decisions are biased towards previous stimuli, a phenomenon known as serial dependence. However, the mechanisms of this bias are unknown. For example, it is debated whether serial dependence reflects a perceptual bias or interference of prior st ...

The shine-through paradigm and the schizophrenia spectrum: a summary

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Simona Adele Garobbio, Janir Nuno Ramos Antunes Da Cruz

In the past 10 years, our laboratory has proved the shine-through paradigm to be a very sensitive endophenotype for schizophrenia. The shine-through paradigm is a visual backward masking task, where the target is a vertical vernier followed by a 25-element ...

Dissecting (un)crowding

Michael Herzog, Alban Bornet, Adrien Christophe Doerig, Oh-Hyeon Choung

In crowding, perception of a target deteriorates in the presence of nearby flankers. Surprisingly, perception can be rescued from crowding if additional flankers are added (uncrowding). Uncrowding is a major challenge for all classic models of crowding and ...

EEG rhythms in long-lasting spatio-temporal feature integration

Michael Herzog, David Pascucci, Maëlan Quentin Menétrey

Pre-stimulus brain activity is thought to modulate visual perception. However, the nature of this modulation remains debated. In particular, the use of paradigms with very brief and weak stimuli complicates a univocal understanding. Here we focus on phenom ...

Novelty is not surprise: Human exploratory and adaptive behavior in sequential decision-making

Wulfram Gerstner, Marco Philipp Lehmann, Michael Herzog, He Xu, Alireza Modirshanechi

Classic reinforcement learning (RL) theories cannot explain human behavior in the absence of external reward or when the environment changes. Here, we employ a deep sequential decision-making paradigm with sparse reward and abrupt environmental changes. To ...

Electrophysiological correlates of visual backward masking in patients with bipolar disorder

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Simona Adele Garobbio, Janir Nuno Ramos Antunes Da Cruz

In visual backward masking (VBM), a target is followed by a mask that decreases target discriminability. Schizophrenia patients (SZ) show strong and reproducible masking impairments, which are associated with reduced EEG amplitudes. Patients with bipolar d ...

Population receptive field size in (un)crowding: to isolate or to combine?

Michael Herzog, Maya Anna Jastrzebowska, Bogdan Draganski, Ayberk Ozkirli

Traditional models posit that visual processing is local and feedforward. In this vein, crowding is explained to be the result of pooling of target and flanker features in early visual areas. Specifically, it has been suggested that when the target and fla ...

About common factors in vision

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Aline Françoise Cretenoud, Lukasz Grzeczkowski, Simona Adele Garobbio, Janir Nuno Ramos Antunes Da Cruz, Dario Alejandro Gordillo Lopez

Often, we intuitively assume that there are common factors in life. For example, we test people with a visual acuity test to determine whether they are allowed to drive a car or not- with the implicit assumption that the acuity test is representative of vi ...

Unraveling brain interactions in vision: the example of crowding

Michael Herzog, Vitaly Chicherov, Maya Anna Jastrzebowska, Bogdan Draganski

Crowding, the impairment of target discrimination in clutter, is the standard situation in vision. Traditionally, crowding is explained with (feedforward) models, in which only neighboring elements interact, leading to a “bottleneck” at the earliest stages ...

A comparative biology approach to DNN modeling of vision: A focus on differences, not similarities

Michael Herzog, Alban Bornet, Adrien Christophe Doerig

Deep neural networks (DNNs) have revolutionized computer science and are now widely used for neuroscientific research. A hot debate has ensued about the usefulness of DNNs as neuroscientific models of the human visual system; the debate centers on to what ...

A guideline for linking brain wave findings to the various aspects of discrete perception

Michael Herzog, Lukas Vogelsang, Maëlan Quentin Menétrey

Brain waves, determined by electrical and magnetic brain recordings (e.g., EEG and MEG), and fluctuating behavioral responses, determined by response time or accuracy measures, are frequently taken to support discrete perception. For example, it has been p ...

Global and high-level effects in crowding cannot be predicted by either high-dimensional pooling or target cueing

Michael Herzog, Alban Bornet, Adrien Christophe Doerig, Mauro Manassi, Oh-Hyeon Choung

In visual crowding, the perception of a target deteriorates in the presence of nearby flankers. Traditionally, target-flanker interactions have been considered as local, mostly deleterious, low-level, and feature specific, occurring when information is poo ...

Information integration and information storage in retinotopic and non-retinotopic sensory memory

Michael Herzog

The first stage of the Atkinson–Shiffrin model of human memory is a sensory memory (SM). The visual component of the SM was shown to operate within a retinotopic reference frame. However, a retinotopic SM (rSM) is unable to account for vision under natural ...

Features integrate along a motion trajectory when object integrity is preserved

Michael Herzog, Leila Drissi Daoudi - Kleinbauer

Information about a moving object is usually poor at each retinotopic location because photoreceptor activation is short, noisy, and affected by shadows, reflections of other objects, and so on. Integration across the motion trajectory may yield a much bet ...

The time course of serial dependence: an interplay between perceptual decisions and task relevant representations

Michael Herzog, Gizay Ceylan, David Pascucci

In serial dependence (SD), features of a present stimulus are judged as similar to previously presented ones. This bias is often explained by a continuity field (CF) in perception, combining similar stimuli in an extended region of space (∼ 15°) and time ( ...

The role of population receptive field size and recurrent processing in learning to “de-crowd”

Michael Herzog, Maya Anna Jastrzebowska, Bogdan Draganski, Ayberk Ozkirli

In crowding, the perception of a target is impeded by surrounding clutter. While traditional models are feedforward and local, there is increasing behavioral and neural evidence for a critical role of recurrent processing across the visual hierarchy in cro ...

Individual differences in the perception of visual illusions are stable across eyes, time, and measurement methods

Michael Herzog, Aline Françoise Cretenoud, Lukasz Grzeczkowski

Vision scientists have tried to classify illusions for more than a century. For example, some studies suggested that there is a unique common factor for all visual illusions. Other studies proposed that there are several subclasses of illusions, such as il ...

Shrinking Bouma's window: How to model crowding in dense displays

Michael Herzog, Gregory Francis, Alban Bornet, Adrien Christophe Doerig

In crowding, perception of a target deteriorates in the presence of nearby flankers. Traditionally, it is thought that visual crowding obeys Bouma's law, i.e., all elements within a certain distance interfere with the target, and that adding more elements ...
