Age-related differences in temporal processing

Visual backward masking paradigm, as determined with the shine-through effect, is a very sensitive tool to detect age related differences in visual temporal processing. We presented a vernier offset to the left or right followed by a grating mask which imp ...

Non-retinotopic feature integration is pre-attentive

Attention operates on non-retinotopic feature maps in visual search

Michael Herzog, Marco Boi

At the heart of feature integration theory is a master map which operates on dimension-based feature maps. It is assumed that these feature maps are organized retinotopically. If in conjunction search, for example, a horizontal green line has to be searche ...

Temporal patterning of 'unlearnable' stimuli types does not always enable learning

Michael Herzog, Carl Kristoffer Aberg

Presenting two or more stimulus types randomly interleaved, so-called roving stimuli, disrupts perceptual learning in many paradigms. It was recently reported that learning with disrupting stimuli types is possible when stimuli are presented in an alternat ...

The roles of mask luminance and perceptual grouping in visual backward masking

Michael Herzog, Gregory Francis

Visual backward masking is a commonly used technique in vision research and psychology. There are two distinct types of masking. Either masking is strongest for a simultaneous presentation of the target and the mask (A-type masking) or masking is strongest ...

Non-retinotopic feature integration decreases response-locked brain activity as revealed by electrical neuroimaging

Michael Herzog, Olaf Blanke, Thomas Otto, Manuel Mercier, Gijs Plomp

When presented with dynamic scenes, the brain integrates visual elements across space and time. Such non-retinotopic processing has been intensively studied from a psychophysical point of view, but little is known about the underlying neural processes. Her ...

Modulation of Attentional Capture by Display Probabilities in Visual Search

Michael Herzog, Bilge Sayim

Attentional capture is often thought to be automatic and not modulable. For example, visual search experiments showed that salient distractor singletons strongly capture attention even when they had to be ignored by the observers. Recently, however, it was ...

Anesthesia prevents auditory perceptual learning

Alain Farron, Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

BACKGROUND: An auditory perceptual learning paradigm was used to investigate whether implicit memories are formed during general anesthesia. METHODS: Eighty-seven patients who had an American Society of Anesthesiologists physical status of I-III and were s ...

Long-lasting modulation of feature integration by transcranial magnetic stimulation

Michael Herzog, Frank Scharnowski, Johannes Rüter

The human brain analyzes a visual object first by basic feature detectors. On the objects way to a conscious percept, these features are integrated in subsequent stages of the visual hierarchy. The time course of this feature integration is largely unknown ...

Pitting temporal against spatial integration in schizophrenic patients

Michael Herzog

Schizophrenic patients show strong impairments in visual backward masking possibly caused by deficits on the early stages of visual processing. The underlying aberrant mechanisms are not clearly understood. Spatial as well as temporal processing deficits h ...

Global stimulus configuration modulates crowding

Michael Herzog, Toni Saarela, Bilge Sayim

In crowding, neighboring elements impair the perception of a peripherally presented target. Crowding is often regarded to be a consequence of spatial pooling of information that leads to the perception of textural wholes. We studied the effects of stimulus ...

Perceptual learning by mental imagery

Michael Herzog, Fred Mast, Elisa Tartaglia, Laura Bamert

In a bisection discrimination task, two vertical outer lines delineate an interval which is bisected by a centre line. Observers indicate whether this centre line is closer to the left or right outer line. Performance in this task improves strongly with tr ...

Deteriorated visual backward masking in the shine-through effect in adolescents with psychosis

Michael Herzog

Visual backward masking is a reliable and widely used tool in schizophrenia research. Whereas many studies have shown masking deficits in adult patients, there are only very few studies with adolescents with psychosis-and with controversial results. Maskin ...

How the mind constitutes itself through perceptual learning

Michael Herzog

Most theories of perception assume a rigid relationship between objects of the physical world and the corresponding mental representations. We show by a priori reasoning that this assumption is not fulfilled. We claim instead that all object-representation ...

Spatial grouping determines temporal integration

Michael Herzog, Frank Scharnowski

To make sense out of a continuously changing visual world, people need to integrate features across space and time. Despite more than a century of research, the mechanisms of features integration are still a matter of debate. To examine how temporal and sp ...

Feature integration across space, time, and orientation

Michael Herzog, Thomas Otto

The perception of a visual target can be strongly influenced by flanking stimuli. In static displays, performance on the target improves when the distance to the flanking elements increases-presumably because feature pooling and integration vanishes with d ...
