Sex moderates the relationship between cognitive disorganisation and visual backward masking: potential implications for an endophenotype of schizophrenia

Michael Herzog, Guillaume Sierro, Christine Mohr

Schizophrenia is a severe mental disorder that impairs individuals’ life, often chronically and from early adulthood on. There is a search for endophenotypes, i.e. stable markers of the genetic underpinnings of the disease. Visual backward masking (VBM) is ...

How the global layout of the mask influences masking strength

Michael Herzog

In visual backward masking, the perception of a target is influenced by a trailing mask. Masking is usually explained by local interactions between the target and the mask representations. However, recently it has been shown that the global spatial layout ...

Grouping, pooling, and when bigger is better in visual crowding

Michael Herzog, Bilge Sayim, Mauro Manassi

In crowding, perception of a target is strongly deteriorated by nearby elements. Crowding is often explained by pooling models predicting that adding flankers increases crowding. In contrast, the centroid hypothesis proposes that adding flankers decreases ...

Visual spatiotemporal processing in the elderly

Michael Herzog

We used backward masking paradigm to investigate the effects of aging on visual spatiotemporal processing. First, thirty-three older (M=65.3 years) and ten younger adults (M=24.3 years) had to indicate the offset direction of a vernier that was masked by a ...

Different types of feedback change decision criterion and sensitivity differently in perceptual learning

Michael Herzog, Carl Kristoffer Aberg

In (perceptual) learning, performance improves with practice either by changes in sensitivity or decision criterion. Often, changes in sensitivity are regarded as the appropriate measure of learning while changes in criterion are considered unavoidable nui ...

The N1 wave amplitude reflects perceptual grouping and correlates with crowding

Michael Herzog, Gijs Plomp, Vitaly Chicherov

In crowding, flanking elements strongly deteriorate performance. For example, vernier offset discrimination is strongly affected by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...

Non-retinotopic feature processing in the absence of retinotopic spatial layout and the construction of perceptual space from motion

Michael Herzog

The spatial representation of a visual scene in the early visual system is well known. The optics of the eye map the three-dimensional environment onto two-dimensional images on the retina. These retinotopic representations are preserved in the early visua ...

Cognitive disorganisation in schizotypy is associated with deterioration in visual backward masking

Michael Herzog, Christine Mohr, Daniela Herzig

To understand the causes of schizophrenia, a search for stable markers (endophenotypes) is ongoing. In previous years, we have shown that the shine-through visual backward masking paradigm meets the most important characteristics of an endophenotype. Here, ...

The visual saliency map is non-retinotopic

Michael Herzog, Marco Boi, Marcus Leonardus Vergeer

Most visual search models rely on a retinotopic saliency map. Here, we provide evidence that visual saliency is computed non-retinotopically. Recently, it was shown that attention can operate in a non-retinotopic reference frame by inserting a search displ ...

Testing dynamical models of vision

Michael Herzog, Gregory Francis, Johannes Rüter

Most models of vision focus either on the spatial or temporal aspects of visual processing and neglect the other component. A variety of studies have shown, however, that spatial and temporal processing cannot easily be separated. The shine-through effect ...

Barrier effects in non-retinotopic feature attribution

Michael Herzog

When objects move in the environment, their retinal images can undergo drastic changes and features of different objects can be inter-mixed in the retinal image. Notwithstanding these changes and ambiguities, the visual system is capable of establishing co ...

Quantifying target conspicuity in contextual modulation by visual search

Michael Herzog, Bilge Sayim

Contextual elements can strongly modulate visual performance. For example, performance deteriorates when a vernier is flanked by neighboring lines. On a neural level, such contextual modulation is often explained by local spatial interactions such as later ...

Motion and tilt aftereffects occur largely in retinal, not in object coordinates

Michael Herzog, Marco Boi

A variety of aftereffects was found to be processed non-retinotopically. Other studies failed to ﬁnd non-retinotopic aftereffects. These experiments relied on paradigms involving eye movements. We have developed a paradigm, based on the Ternus–Pikler displ ...

The time course of perceptual grouping: a high density ERP study

Michael Herzog, Gijs Plomp, Vitaly Chicherov

Performance on a target can be strongly modified by context. For example, vernier offset discrimination is strongly deteriorated by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...

Non-retinotopic perceptual learning

Michael Herzog, Thomas Otto

Perceptual learning is usually specific for the encoded stimuli. For example, improvements in performance for a certain stimulus do not transfer if the stimulus is rotated by 90 degree or is presented at a different location. These findings are usually tak ...

Attention modulates spatio-temporal grouping

Michael Herzog

Dynamic stimuli are ubiquitous in natural viewing conditions implying that grouping operations need to operate, not only in space, but also jointly in space and time. Moreover, in natural viewing, attention plays an important role in controlling how resour ...

The neural correlates of the shine-through effect as revealed by high-density EEG

Michael Herzog, Yvonne Evelina Thunell, Gijs Plomp

When a briefly presented vernier stimulus is followed by a grating consisting of 25 lines, the vernier appears brighter, longer, wider, and superimposed on the grating (shine-through). However, the vernier is largely invisible if two of the lines in the gr ...
