Visual backward masking is a very sensitive tool for studying early visual processing deficits and a reliable endophenotype of schizophrenia. Mental diseases strongly overlap in many aspects, for example, in psychopathology, cognition, and genetics. Here, ...

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 ...

What to Choose Next? A Paradigm for Testing Human Sequential Decision Making

Michael Herzog, Aaron Michael Clarke

Many of the decisions we make in our everyday lives are sequential and entail sparse rewards. While sequential decision-making has been extensively investigated in theory (e.g., by reinforcement learning models) there is no systematic experimental paradigm ...

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 ...

A two-stage model of decision making

Michael Herzog, Adrien Christophe Doerig, Leila Drissi Daoudi - Kleinbauer

The drift diffusion model (Ratcliff, 1978) is widely used to model binary decision-making. In this model, evidence for the two alternatives is integrated over time until it hits a decision boundary leading to a reaction. The drift diffusion model fits many ...

Retinotopy of visual masking and non-retinotopic perception during masking

Michael Herzog

Due to the movements of the observer and those of objects in the environment, retinotopic representations are highly unstable during ecological viewing conditions. The phenomenal stability of our perception suggests that retinotopic representations are tra ...

No correlations between the strength of visual illusions

Michael Herzog, Aaron Michael Clarke, Lukasz Grzeczkowski

In cognition, audition, and somatosensation, performance correlates strongly between different paradigms suggesting the existence of common factors. Surprisingly, this does not hold true for vision. For example, performance in line bisection and visual acu ...

One-shot learning and behavioral eligibility traces in sequential decision making

Michael Herzog, Wulfram Gerstner, Kerstin Preuschoff, He Xu, Marco Philipp Lehmann, Vasiliki Liakoni

In many daily tasks, we make multiple decisions before reaching a goal. In order to learn such sequences of decisions, a mechanism to link earlier actions to later reward is necessary. Reinforcement learning (RL) theory suggests two classes of algorithms s ...

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 ...

Neural Correlates of Sequential Decision Making

Michael Herzog, He Xu

In chess, a series of moves is made until a delayed sparse feedback (win, loss) is issued, which makes it impossible to evaluate the value of a single move. There are powerful reinforcement learning (RL) algorithms, which can cope with these sequential dec ...

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 ...

Individual differences in the Müller-Lyer and Ponzo illusions are stable across different contexts

Michael Herzog, Lukasz Grzeczkowski, Aline Françoise Cretenoud

Vision scientists have attempted to classify visual illusions according to certain aspects, such as brightness or spatial features. For example, Piaget proposed that visual illusion magnitudes either decrease or increase with age. Subsequently, it was sugg ...

The individual structure of visual space

Michael Herzog, Gregory Francis, Lukasz Grzeczkowski, Albulena Jashari-Shaqiri, Aline Françoise Cretenoud

Common factors are ubiquitous. First, we show that, however in vision, correlations of performance in similar paradigms are low even though test-retest reliability is high. Second, one might expect that correlations increase with increasing age because of ...

Capsule networks, but not convolutional networks explain global configurational visual effects

Michael Herzog, Adrien Christophe Doerig, Alban Bornet

In human vision, perception of local features depends on all elements in the visual field and their exact configuration. For example, observers performed a vernier discrimination task. When a surrounding square was added to the vernier, the task became muc ...
