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 ...

How are non-retinotopic motion signals integrated? -A high-density EEG study

Michael Herzog, Yvonne Evelina Thunell, Gijs Plomp

Objects moving in the visual scene cause retinal displacements that are not the result of motor commands and thus cannot be accounted for by efference copies. Yet, we easily keep track of moving objects even without following them with our gaze. Here, we i ...

Electrophysiological signatures of crowding are similar in foveal and peripheral vision

Michael Herzog, Vitaly Chicherov

Flankers can strongly deteriorate performance on a visual target (crowding). For example, vernier offset discrimination strongly deteriorates when neighbouring flankers are presented. Interestingly, performance for longer and shorter flankers is better tha ...

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 ...

Binocular suppression occurs in object-centered coordinates

Michael Herzog, Marco Boi, Marcus Leonardus Vergeer

In binocular rivalry, only one image is perceived consciously when different, incompatible images are presented to the left and right eye, respectively. The other image is suppressed. Binocular suppression is generally assumed to occur within retinotopic c ...

Age-related changes in visually evoked electrical brain activity

Michael Herzog, Gijs Plomp

Whereas much is known about the degenerative effects of aging on cortical tissue, less is known about how aging affects visually evoked electrical activity, and at what latencies. We compared visual processing in elderly and young controls using a visual m ...

Decoding stimulus-related information from single-trial EEG responses based on voltage topographies

Michael Herzog, Gijs Plomp, Athina Tzovara

Neuroimaging studies typically compare experimental conditions using average brain responses, thereby overlooking the stimulus-related information conveyed by distributed spatio-temporal patterns of single-trial responses. Here, we take advantage of this r ...

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 ...

Perceptual learning, roving and the unsupervised bias

Wulfram Gerstner, Nicolas Frémaux, Michael Herzog, Carl Kristoffer Aberg

Perceptual learning improves perception through training. Perceptual learning improves with most stimulus types but fails when certain stimulus types are mixed during training (roving). This result is surprising because classical supervised and unsupervise ...

Perceptual learning of motion discrimination by mental imagery

Michael Herzog, Fred Mast, Elisa Tartaglia, Laura Bamert

Perceptual learning can occur when stimuli are only imagined, i.e., without proper stimulus presentation. For example, perceptual learning improved bisection discrimination when only the two outer lines of the bisection stimulus were presented and the cent ...

Trait anxiety and post-learning stress do not affect perceptual learning

Maria del Carmen Sandi Perez, Michael Herzog, Carl Kristoffer Aberg, Aaron Michael Clarke

While it is well established that stress can modulate declarative learning, very few studies have investigated the influence of stress on non-declarative learning. Here, we studied the influence of post-learning stress, which effectively modulates declarat ...

How alcohol intake affects visual temporal processing

Michael Herzog

Alcohol affects vision. However, the influence of alcohol on visual processing is largely unknown. Here, we investigated the effects of alcohol on visual spatiotemporal processing. We employed a visual paradigm, the shine through backward masking paradigm, ...

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 ...

Neural correlates of non-retinotopic motion integration

Michael Herzog, Yvonne Evelina Thunell, Gijs Plomp

Under normal viewing conditions, due to the motion of objects and to eye movements, the retinotopic representation of the environment constantly changes. Yet we perceive the world as stable, and we easily keep track of moving objects. Here, we investigated ...

Crowding suppresses the N1 wave

Michael Herzog, Gijs Plomp, Vitaly Chicherov

Flankers can strongly deteriorate performance on a visual target (crowding). For example, vernier offset discrimination is strongly affected by neighboring flankers. Interestingly, performance for longer and shorter flankers is better than performance for ...

Patients with functional psychoses show similar visual backward masking deficits

Michael Herzog, Maya Roinishvili

Recent genetic, behavioral, and clinical studies suggest that functional psychoses (schizophrenia, bipolar disorder, schizoaffective disorder), previously thought to be distinct from each other, may belong to one continuum. The shine-through masking paradi ...

About similar characteristics of visual perceptual learning and LTP

Michael Herzog, Carl Kristoffer Aberg

Perceptual learning is an implicit form of learning which induces long-lasting perceptual enhancements. Perceptual learning shows intriguing characteristics. For example, a minimal number of trials per session is needed for learning and the interleaved pre ...

Backward masking reveals different visual processing of schizophrenic and depressive patients

Michael Herzog, Maya Roinishvili

Visual backward masking is a very sensitive tool for studying early visual processing deficits and a reliable endophenotype of schizophrenia. Mental diseases strongly overlap in many aspects, for example, in psychopathology, cognition, and genetics. Here, ...
