Body Context and Posture Affect Mental Imagery of Hands

Olaf Blanke, Bogdan Draganski, Silvio Ionta

Different visual stimuli have been shown to recruit different mental imagery strategies. However the role of specific visual stimuli properties related to body context and posture in mental imagery is still under debate. Aiming to dissociate the behavioura ...

Self-motion holds a special status in visual processing

Roy Salomon

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 ...

Testing dynamical models of vision

Michael Herzog, Gregory Francis, Johannes Rüter

Most models of vision focus either on the spatial or temporal aspects of visual processing and neglect the other component. A variety of studies have shown, however, that spatial and temporal processing cannot easily be separated. The shine-through effect ...

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 ...

Spatiotemporal dynamics of visual vertical judgments: early and late brain mechanisms as revealed by high-density electrical neuroimaging

Olaf Blanke, Christophe Lopez, Manuel Mercier, Pär Halje

Constructing and updating an internal model of verticality is fundamental for maintaining an erect posture and facilitating visuo-spatial processing. The judgment of the visual vertical (VV) has been intensively studied in psychophysical investigations and ...

Combining vernier acuity and visual backward masking as a sensitive test for visual temporal deficits in aging research

Michael Herzog, Maya Roinishvili

Performance in many everyday situations slows down when age increases. The causes of slowing down may be found on any stage of information processing. Here, we show that the combination of a vernier acuity task and the shine-through backward masking paradi ...

Early visual processing deficits in the elderly: anterior increases and posterior decreases of electrical source activity

Michael Herzog, Maya Roinishvili, Gijs Plomp

We compared temporal processing in elderly and young controls using EEG and electrical neuroimaging. Subjects discriminated the offset direction of Vernier stimuli in four conditions: Vernier only, mask only, Vernier immediately followed by a mask, and Ver ...

Time course of visual information processing in adolescents

Michael Herzog

Visual backward masking is a well suited technique to investigate intact and deficient visual information processing. Whereas visual backward masking has been studied extensively in adult populations, there is only a limited number of investigations in ado ...

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 ...
