Does perceptual learning suffer from retrograde interference?

Michael Herzog, Carl Kristoffer Aberg

In motor learning, training a task B can disrupt improvements of performance of a previously learned task A, indicating that learning needs consolidation. An influential study suggested that this is the case also for visual perceptual learning [1]. Using t ...

Non-retinotopic capture of exogenous attention

Orientation specificity of learning vernier discriminations

Michael Herzog

Orientation selective neurons in the primary visual cortex typically respond to a range of orientations that covers 20, or more, while in psychophysical experiments, orientation bandwidth is often clearly narrower. Here, we measure the orientation specific ...

The shine-through masking paradigm is a potential endophenotype of schizophrenia

Michael Herzog, Maya Roinishvili

Background: To understand the genetics of schizophrenia, a hunt for so-called intermediate phenotypes or endophenotypes is ongoing. Visual masking has been proposed to be such an endophenotype. However, no systematic study has been conducted yet to prove t ...

Electrophysiological correlates of visual masking deficits in schizophrenia

Attention and non-retinotopic feature integration

Michael Herzog, Thomas Otto

Features of moving objects are non-retinotopically integrated along their motion trajectories as demonstrated by a variety of recent studies. The mechanisms of non-retinotopic feature integration are largely unknown. Here, we investigated the role of atten ...

Gestalt Factors Modulate Basic Spatial Vision

Michael Herzog, Bilge Sayim

Human perception of a stimulus varies depending on the context in which the stimulus is presented. Such contextual modulation has often been explained by two basic neural mechanisms: lateral inhibition and spatial pooling. In the present study, we presente ...

First-order relatives of schizophrenic patients are not impaired in the Continuous Performance Test

Michael Herzog, Maya Roinishvili

Sustained attention deficits measured by the Continuous Performance Test (CPT) have been reportedly proposed as an endophenotype of schizophrenia. One requirement for an endophenotype is that unaffected first-order relatives must show deteriorated performa ...

Perceptual learning in a nonretinotopic frame of reference

Michael Herzog, Thomas Otto

Perceptual learning is the ability to improve perception through practice. Perceptual learning is usually specific for the task and features learned. For example, improvements in performance for a certain stimulus do not transfer if the stimulus is rotated ...

In contextual modulation, bigger is not better for low luminance stimuli

Michael Herzog, Bilge Sayim, Mauro Manassi

Performance on a target can be modified by contextual elements. For example, thresholds strongly increase when a vernier is flanked by two lines. Increasing the number of flankers reduces contextual interference when the flankers are shorter or longer than ...

Combining TMS and EEG: A touchstone for artifact removal

Time course of visual information processing in adolescents

Michael Herzog

Visual backward masking is a well suited technique to investigate intact and deficient visual information processing. Whereas visual backward masking has been studied extensively in adult populations, there is only a limited number of investigations in ado ...

Effects of alcohol on the time course of visual information processing in woman

Michael Herzog

Alcohol is one of the most commonly consumed drugs in the world. While the effects of alcohol on cognitive and psychomotor skills have been well studied, little research has examined alcohol's effects on visual processing. In the present study, we evaluate ...

Contextual Modulation and Gestalt

Michael Herzog, Bilge Sayim

The perception of a stimulus can strongly be modified by its spatial context. For example, when a vernier stimulus is flanked by two lines, performance deteriorates compared to a vernier without flanks. This is usually explained by local interactions, such ...

Perceptual learning with Chevrons requires a minimal number of trials, transfers to untrained directions, but does not require sleep

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

In most models of perceptual learning, the amount of improvement of performance does not depend on the regime of stimulus presentations, but only on the sheer number of trials. Here, we kept the number of stimulus presentations constant while varying the n ...

A (fascinating) litmus test for human retino- vs. non-retinotopic processing

Michael Herzog, Thomas Otto, Marco Boi

In human vision, the optics of the eye map neighboring points of the environment onto neighboring photoreceptors in the retina. This retinotopic encoding principle is preserved in the early visual areas. Under normal viewing conditions, due to the motion o ...

Non-retinotopic feature integration has a neural pace of its own, as revealed by electrical brain imaging

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

When elements appear in quick succession they can integrate across space and time. Using high-density EEG techniques we show that such non-retinotopic feature integration is not time-locked to stimulus onset, but has a timing of its own. We presented a cen ...

Perceptual learning and roving: Stimulus types and overlapping neural populations

Michael Herzog, Elisa Tartaglia, Carl Kristoffer Aberg

In perceptual learning, performance usually improves when observers train with one type of stimulus, for example, a bisection stimulus. Roving denotes the situation when, instead of one, two or more types of stimuli are presented randomly interleaved, for ...
