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 ...

We present the results of the EUMSSI team's participation in the Multimodal Person Discovery task at the MediaEval challenge 2015. The goal is to identify all people who simultaneously appear and speak in a video corpus, which implicitly involves both audi ...

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 ...

A neuropsychological instrument measuring age-related cerebral decline in older drivers: development reliability, and validity of MedDrive

Michael Herzog, Daniela Herzig, Isabel Cardoso, Paul Vaucher

When facing age-related cerebral decline, older adults are unequally affected by cognitive impairment without us knowing why. To explore underlying mechanisms and find possible solutions to maintain life-space mobility, there is a need for a standardized b ...

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 ...

Frontiers Research Foundation2014

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 ...

Frontiers Research Foundation2013

Visual search is a good illustration about how the brain coordinates a variety of functions such as visual clues extraction from the scene, coordination of the eye-movements, accumu- lation of visual information and visual recognition. It has an important ...

Long-lasting visual integration of form, motion, and color as revealed by visual masking

Michael Herzog

When two similar visual stimuli are presented in rapid succession at the same location, they fuse. For example, a red and a green disk are perceived as one single yellow disk. Likewise, verniers with opposite offset directions are perceived as one vernier ...
