Risk prediction error signaling: A two-component response?

Michael Herzog, Ophélie Gladys Favrod, Kerstin Preuschoff, Marc Michael Lauffs, Sophie Alberta Catherine Geoghan

Organisms use rewards to navigate and adapt to (uncertain) environments. Error-based learning about rewards issupported by the dopaminergic system, which is thought to signal reward prediction errors to make adjustmentsto past predictions. More recently, t ...

Reference-frames in vision: Contributions of attentional tracking to nonretinotopic perception in the Ternus-Pikler display

Michael Herzog, Marc Michael Lauffs, Oh-Hyeon Choung

Perception depends on reference frames. For example, the "true'' cycloidal motion trajectory of a reflector on a bike's wheel is invisible because we perceive the reflector motion relative to the bike's motion trajectory, which serves as a reference frame. ...

Investigating prospective memory via eye tracking: No evidence for a monitoring deficit in older adults

Michael Herzog, Marc Michael Lauffs

Prospective memory (PM) refers to remembering to perform intended actions in the future. Older adults in particular have been shown to be negatively affected by PM tasks that require a high amount of attentional resources (i.e., nonfocal tasks). This age-r ...

Unconscious retinotopic motion processing affects non-retinotopic motion perception

Unpredictability does not hamper nonretinotopic motion perception

Michael Herzog, Marc Michael Lauffs

The motion of parts of an object is usually perceived relative to the object, i.e., nonretinotopically, rather than in retinal coordinates. For example, we perceive a reflector to rotate on the wheel of a moving bicycle even though its trajectory is cycloi ...

Eyetracking shows the source of age-related differences in prospective memory: Older adults monitor well, but fail to take action

Michael Herzog, Marc Michael Lauffs

Older adults often perform worse than younger adults on prospective memory tasks, but the exact mechanisms remain elusive. Participants had to indicate whether a letter in the center of gaze is a vocal or a consonant (ongoing task). The prospective memory ...

From retinotopic processing to nonretinotopic representation

Marc Michael Lauffs

Encoding of visual information in the brain is retinotopic: Neighboring points in the visual field are mapped onto neighboring photoreceptors in the retina, and these neighborhood relations are maintained in the early stages of cortical processing. However ...

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

Michael Herzog, Maya Roinishvili, Marc Michael Lauffs, Albulena Jashari-Shaqiri

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 ...

Retinotopic information is rendered invisible by non-retinotopic processing

Michael Herzog, Marc Michael Lauffs

Classically, stimuli are rendered unconscious by backward masking or binocular rivalry, where it is usually assumed that the mask or the stimulus in the contralateral eye suppress the target. Based, on the Ternus-Pikler display (http://lpsy.epfl.ch/researc ...

The effects of spatial attention on temporal integration

Michael Herzog, Marc Michael Lauffs

Feature fusion reflects temporal integration. Previous studies mostly employed foveal presentations with no attention manipulation. In this study we examined the effects of sustained spatial attention on temporal integration using feature-fusion with perip ...

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

Schizophrenia impairs cognitive function as much as perception. For example, patients perceive global motion in random dot kinematograms less strongly, because the integration of the dots into a single Gestalt is complex (e.g., Chen, Nakayama, Levy, Matthy ...
