The Silent Period of Evidence Integration in Fast Decision Making

Wulfram Gerstner, Michael Herzog, Johannes Rüter

In a typical experiment on decision making, one out of two possible stimuli is displayed and observers decide which one was presented. Recently, Stanford and colleagues (2010) introduced a new variant of this classical one-stimulus presentation paradigm to ...

Paradoxical Evidence Integration in Rapid Decision Processes

Wulfram Gerstner, Nicolas Marcille, Michael Herzog, Johannes Rüter

Decisions about noisy stimuli require evidence integration over time. Traditionally, evidence integration and decision making are described as a one-stage process: a decision is made when evidence for the presence of a stimulus crosses a threshold. Here, w ...

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 ...

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 ...

Feature integration but not feature separation can be modulated by TMS

Michael Herzog, Johannes Rüter

How the brain integrates visual information across time into coherent percepts is an open question. Here, we investigated this integration using a feature fusion paradigm. In feature fusion, two stimuli are presented in immediate succession. The stimuli ar ...

Cortical processing of near-threshold tactile stimuli: an MEG study

Johannes Rüter

In the present study we tested the applicability of a paired-stimulus paradigm for the investigation of near-threshold (NT) stimulus processing in the somatosensory system using magnetoencephalography. Cortical processing of the NT stimuli was studied indi ...

When transcranial magnetic stimulation (TMS) modulates feature integration

Michael Herzog, Johannes Rüter

How the brain integrates visual information across time into coherent percepts is an open question. Here, we presented two verniers with opposite offset directions one after the other. A vernier consists of two vertical bars that are horizontally offset. W ...

Long-lasting modulation of feature integration by transcranial magnetic stimulation

Michael Herzog, Frank Scharnowski, Johannes Rüter

The human brain analyzes a visual object first by basic feature detectors. On the objects way to a conscious percept, these features are integrated in subsequent stages of the visual hierarchy. The time course of this feature integration is largely unknown ...

How TMS and stimulus off/on signals modulate feature integration

Michael Herzog, Frank Scharnowski, Johannes Rüter

When a right offset vernier is immediately followed by a left offset vernier (or vice versa), only one vernier is perceived. Feature fusion has occurred. In feature fusion, observers cannot resolve the two verniers individually. Subjects perform at chance ...
