Local versus global and retinotopic versus non-retinotopic motion processing in schizophrenia patients

Michael Herzog, Maya Roinishvili, Marc Michael Lauffs

Schizophrenia impairs cognitive functions as much as perception. For example, patients perceive global motion in random dot kinematograms less strongly, because, as it is argued, the integration of the dots into a single Gestalt is complex and therefore de ...

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 ...

Inferring the direction of implied motion depends on visual awareness

Nathan Quentin Faivre

Visual awareness of an event, object, or scene is, by essence, an integrated experience, whereby different visual features composing an object (e.g., orientation, color, shape) appear as an unified percept and are processed as a whole. Here, we tested in h ...

Tonotopic mapping of human auditory cortex

Melissa Saenz

Since the early days of functional magnetic resonance imaging (fMRI), retinotopic mapping emerged as a powerful and widely-accepted tool, allowing the identification of individual visual cortical fields and furthering the study of visual processing. In con ...

A direct comparison of unconscious face processing under masking and interocular suppression

Nathan Quentin Faivre, Julien Dubois

Different combinations of forward and backward masking as well as interocular suppression have been used extensively to render stimuli invisible and to study those aspects of visual stimuli that are processed in the absence of conscious experience. Althoug ...

Schizophrenia and visual backward masking: a general deficit of target enhancement

Michael Herzog, Maya Roinishvili

The obvious symptoms of schizophrenia are of cognitive and psychopathological nature. However, schizophrenia affects also visual processing which becomes particularly evident when stimuli are presented for short durations and are followed by a masking stim ...

The temporal dynamics of feature integration for color and form

Michael Herzog

When two visual stimuli are presented in rapid succession only one fused image is perceived. For example, a red disk followed by a green disk is perceived as a single yellow disk (e.g., Efron, Perc Psychophys, 1973). For two verniers that last 30ms each, i ...

Act Quickly, Decide Later: Long-latency Visual Processing Underlies Perceptual Decisions but Not Reflexive Behavior

Humans largely guide their behavior by their visual representation of the world. Recent studies have shown that visual information can trigger behavior within 150 msec, suggesting that visually guided responses to external events, in fact, precede consciou ...

2011

Agency plays an important role in self-recognition from motion. Here, we investigated whether our own movements benefit from preferential processing even when the task is unrelated to self-recognition, and does not involve agency judgments. Participants se ...

Dynamics of Visual Feature Integration and Decision Making

Johannes Rüter

The human brain analyzes a visual object first by basic feature detectors. These features are integrated in subsequent stages of the visual hierarchy. Generally it is assumed that the information about these basic features is lost once the information is s ...
