Binocular suppression occurs in object-centered coordinates

Michael Herzog, Marco Boi, Marcus Leonardus Vergeer

In binocular rivalry, only one image is perceived consciously when different, incompatible images are presented to the left and right eye, respectively. The other image is suppressed. Binocular suppression is generally assumed to occur within retinotopic c ...

Nonretinotopic Exogenous Attention

Michael Herzog, Marco Boi, Marcus Leonardus Vergeer

Attention is crucial for visual perception because it allows the visual system to effectively use its limited resources by selecting behaviorally and cognitively relevant stimuli from the large amount of information impinging on the eyes. Reflexive, stimul ...

Motion and tilt aftereffects occur largely in retinal, not in object, coordinates in the Ternus-Pikler display

Michael Herzog, Marco Boi

Recent studies have shown that a variety of aftereffects occurs in a non-retinotopic frame of reference. These findings have been taken as strong evidence that remapping of visual information occurs in a hierarchic manner in the human cortex with an increa ...

The visual saliency map is non-retinotopic

Michael Herzog, Marco Boi, Marcus Leonardus Vergeer

Most visual search models rely on a retinotopic saliency map. Here, we provide evidence that visual saliency is computed non-retinotopically. Recently, it was shown that attention can operate in a non-retinotopic reference frame by inserting a search displ ...

Motion and tilt aftereffects occur largely in retinal, not in object coordinates

Michael Herzog, Marco Boi

A variety of aftereffects was found to be processed non-retinotopically. Other studies failed to ﬁnd non-retinotopic aftereffects. These experiments relied on paradigms involving eye movements. We have developed a paradigm, based on the Ternus–Pikler displ ...

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 ...

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 ...

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 motion induced by a Ternus-Pikler display

Michael Herzog, Thomas Otto, Marco Boi

Motion processing is usually deemed to rely on retinotopic coordinates. Using a Ternus-Pikler display, we present an instance in which coherent motion of a dot can only be perceived when its position is integrated non-retinotopically. The stimulus consists ...
