A New Approach to Non-Retinotopic Processing

Marco Boi

At every moment, the image the world projects on our eyes undergoes rapid and dramatic changes due to the eye movements and to the motion of the objects. Surprisingly, we are not aware of these changes, experiencing the world as stable and constant. This a ...

Automatic grouping of regular structures

Michael Herzog, Frank Scharnowski

To cope with the continuously incoming stream of input, the visual system has to group information across space and time. Usually, spatial and temporal grouping are investigated separately. However, recent findings revealed that these two grouping mechanis ...

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 ...

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 ...

Age-related differences in temporal processing

Michael Herzog, Maya Roinishvili

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 ...

Schizophrenic and bipolar patients reveal identical backward masking deficits

Michael Herzog, Maya Roinishvili

In visual backward masking, a target is followed by a blank screen (ISI) and, then, a mask which deteriorates target processing. Schizophrenic patients show strong but complex processing deficits in visual masking compared to healthy controls. There is evi ...

Figural grouping affects contextual modulation in low level vision

Michael Herzog, Bilge Sayim

Embedding a target within contextual elements can influence performance in visual tasks. For example, when a vernier is flanked by two lines, discrimination performance deteriorates strongly compared to unflanked presentation. This contextual modulation is ...

Modeling spatial and temporal aspects of visual backward masking

Michael Herzog, Wulfram Gerstner, Gediminas Luksys

Visual backward masking is a versatile tool for understanding principles and limitations of visual information processing in the human brain. However, the mechanisms underlying masking are still poorly understood. In the current contribution, the authors s ...

Visual masking and the dynamics of human perception, cognition, and consciousness: A century of progress, a contemporary synthesis, and future directions

Michael Herzog, Gregory Francis

The 1990s, the "decade of the brain", witnessed major advances in the study of visual perception, cognition, and consciousness. Impressive techniques in neurophysiology, neuroanatomy, neuropsychology, electrophysiology, psychophysics and brain-imaging were ...

Spatial processing and visual backward masking

Michael Herzog

Most theories of visual masking focus primarily on the temporal aspects of visual information processing, strongly neglecting spatial factors. In recent years, however, we have shown that this position is not tenable. Spatial aspects cannot be neglected in ...
