No correlations between the magnitude of visual illusions

Michael Herzog, Fred Mast, Aaron Michael Clarke, Lukasz Grzeczkowski

In cognition, audition and somatosensation, performance correlates strongly between different tasks suggesting the existence of common factors. Surprisingly, this does not hold true for vision. For example, Vernier acuity and Gabor detection correlate very ...

Intact crowding and temporal masking in dyslexia

Michael Herzog, Mauro Manassi

Phonological deficits in dyslexia are well documented. However, there is an ongoing discussion about whether visual deficits limit the reading skills of people with dyslexia. Here, we investigated visual crowding and backward masking. We presented a Vernie ...

Field-like interactions between motion-based reference frames

Michael Herzog

A reference frame is required to specify how motion is perceived. For example, the motion of part of an object is usually perceived relative to the motion of the object itself. Johansson (Psychological Research, 38, 379-393, 1976) proposed that the percept ...

Visual masking & schizophrenia

Michael Herzog

Visual masking is a frequently used tool in schizophrenia research. Visual masking has a very high sensitivity and specificity and masking paradigms have been proven to be endophenotypes. Whereas masking is a powerful technique to study schizophrenia, the ...

Release of crowding by pattern completion

Michael Herzog, Gregory Francis, Mauro Manassi

In crowding, target perception deteriorates in the presence of flanking elements. Crowding is classically explained by low-level mechanisms such as pooling or feature substitution. However, we have previously shown that perceptual grouping between the targ ...

Ageing and visual spatiotemporal processing

Michael Herzog

Ageing affects many visual functions. Here, we investigated the effects of ageing on vernier acuity and backward masking using the shine-through paradigm. We divided healthy older adults (> 60 years) into two groups depending on whether vernier duration wa ...

Linking perceptual learning with identical stimuli to imagery perceptual learning

Michael Herzog, Fred Mast, Elisa Tartaglia, Lukasz Grzeczkowski

Perceptual learning is usually thought to be exclusively driven by the stimuli presented during training (and the underlying synaptic learning rules). In some way, we are slaves of our visual experiences. However, learning can occur even when no stimuli ar ...

Schizophrenia patients and 22q11.2 deletion syndrome adolescents at risk express the same deviant patterns of resting state EEG microstates: A candidate endophenotype of schizophrenia

Dimitri Nestor Alice Van De Ville, Michael Herzog, Fikret Isik Karahanoglu, Maya Roinishvili, Maude Schneider

Schizophrenia is a complex psychiatric disorder and many of the factors contributing to its pathogenesis are poorly understood. In addition, identifying reliable neurophysiological markers would improve diagnosis and early identification of this disease. T ...

Evaluating endophenotypes across and within the schizophrenia-spectrum

Michael Herzog, Christine Mohr

Uncorking the bottleneck of crowding: a fresh look at object recognition

Michael Herzog, Mauro Manassi

In crowding, the perception of a target deteriorates in the presence of clutter. Crowding is usually explained within the framework of object recognition, where processing proceeds in a hierarchical and feedforward fashion from the analysis of low level fe ...

Reference-Frame Selection in Motion Perception

Michael Herzog

Association for Research in Vision and Ophthalmology2015

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 ...

Spatial properties of non-retinotopic reference frames in human vision

Michael Herzog

Many visual attributes of a target stimulus are computed according to dynamic, non-retinotopic reference frames. For example, the motion trajectory of a reflector on a bicycle wheel is perceived as orbital, even though it is in fact cycloidal in retinal, a ...

No correlations between visual illusion strength

The effective reference frame in perceptual judgments of motion direction

Michael Herzog

The retinotopic projection of stimulus motion depends both on the motion of the stimulus and the movements of the observer. In this study, we aimed to quantify the contributions of endogenous (retinotopic) and exogenous (spatiotopic and motion-based) refer ...

No correlations between the strength of visual illusions

Michael Herzog, Fred Mast, 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 ...

Crowding and shape representations

Michael Herzog, Mauro Manassi, Aaron Michael Clarke

In crowding, target perception deteriorates when flanking elements are added. Crowding is traditionally characterized by target-flanker interactions which are (1) deleterious, (2) spatially confined within Bouma’s window, and (3) feature specific. Here, we ...

Crowding, grouping, and object recognition: A matter of appearance

Michael Herzog, Bilge Sayim, Mauro Manassi, Vitaly Chicherov

In crowding, the perception of a target strongly deteriorates when neighboring elements are presented. Crowding is usually assumed to have the following characteristics. (a) Crowding is determined only by nearby elements within a restricted region around t ...
