Beyond Bouma's window: How to explain global aspects of crowding?

Michael Herzog, Gregory Francis, Alban Bornet, Adrien Christophe Doerig, Aaron Michael Clarke

In crowding, perception of an object deteriorates in the presence of nearby elements. Although crowding is a ubiquitous phenomenon, since elements are rarely seen in isolation, to date there exists no consensus on how to model it. Previous experiments show ...

No Evidence for a Common Factor Underlying Visual Abilities in Healthy Older People

Michael Herzog, Aaron Michael Clarke, Aline Françoise Cretenoud, Albulena Jashari-Shaqiri

The world's population is aging at an increasing rate. Even in the absence of neurodegenerative disorders, healthy aging affects perception and cognition. In the context of cognition, common factors are well established. Much less is known about common fac ...

About individual differences in vision

Michael Herzog, Fred Mast, Gregory Francis, Aaron Michael Clarke, Lukasz Grzeczkowski

In cognition, audition, and somatosensation, performance strongly correlates between different paradigms, which suggests the existence of common factors. In contrast, visual performance in seemingly very similar tasks, such as visual and bisection acuity, ...

What to Choose Next? A Paradigm for Testing Human Sequential Decision Making

Michael Herzog, Elisa Tartaglia, Aaron Michael Clarke

Many of the decisions we make in our everyday lives are sequential and entail sparse rewards. While sequential decision-making has been extensively investigated in theory (e.g., by reinforcement learning models) there is no systematic experimental paradigm ...

Towards a Unifying Model of Crowding: Model Olympics

A factorial approach in aging research

Michael Herzog, Aaron Michael Clarke, Albulena Jashari-Shaqiri

The population of developed countries is aging at an ever increasing rate. Even in the absence of neurodegenerative diseases, aging affects perceptual and cognitive functions that are crucial for everyday life. The effects of healthy aging on cognitive abi ...

Multi-factorial approach in aging research

Michael Herzog, Aaron Michael Clarke, Albulena Jashari-Shaqiri

Aging affects all kinds of human functions including perception and cognition. In most perceptual studies, one paradigm is tested and it is usually found that older participants perform worse than younger participants. Implicitly, these results are taken a ...

Multi-factorial approach in aging research

Michael Herzog, Aaron Michael Clarke, Albulena Jashari-Shaqiri

The developed world is aging faster than ever before. Even in the absence of neurodegenerative disease, aging affects all kinds of human functions including perception and cognition. In most perceptual studies, one paradigm is tested and it is usually foun ...

Motion-based nearest vector metric for reference frame selection in the perception of motion

Michael Herzog, Aaron Michael Clarke

We investigated how the visual system selects a reference frame for the perception of motion. Two concentric arcs underwent circular motion around the center of the display, where observers fixated. The outer (target) arc's angular velocity profile was mod ...

Tell me about your Ponzo and I will tell you who you are

Michael Herzog, Fred Mast, Aaron Michael Clarke, Lukasz Grzeczkowski

Unlike in cognition, audition and somatosensation, performance between various visual tasks does not correlate. Surprisingly, even tasks that appear similar, like visual acuity and line bisection task do not share much common variance. Similar results were ...

A computational model for reference-frame synthesis with applications to motion perception

Michael Herzog, Aaron Michael Clarke

As discovered by the Gestaltists, in particular by Duncker, we often perceive motion to be within a non-retinotopic reference frame. For example, the motion of a reflector on a bicycle appears to be circular, whereas, it traces out a cycloidal path with re ...

Is there a common cause for perceptual decline in the aging brain?

Michael Herzog, Aaron Michael Clarke, Albulena Jashari-Shaqiri

Even in the absence of neurodegenerative disease, aging strongly affects vision. Whereas optical deficits are well documented, much less is known perceptual deficits. In most perceptual studies, one paradigm is tested and it is usually found that older par ...

Models of crowding: a comparative study

Michael Herzog, Gregory Francis, Adrien Christophe Doerig, Aaron Michael Clarke

In crowding, the perception of an object deteriorates in the presence of nearby elements. Obviously, crowding is a ubiquitous phenomenon, since elements are rarely seen in isolation. Despite this ubiquity, there exists no consensus on how to model crowding ...

What crowding can tell us about object representations

Michael Herzog, Mauro Manassi, Aaron Michael Clarke

In crowding, perception of a target usually deteriorates when flanking elements are presented next to the target. Surprisingly, adding further flankers can lead to a release from crowding. In previous work we showed that, for example, vernier offset discri ...

The effects of aging on perception and cognition

Crowding and shape representations

Michael Herzog, Mauro Manassi, Aaron Michael Clarke

In crowding, target perception deteriorates when flanking elements are added. Crowding is traditionally characterized by target-flanker interactions which are (1) deleterious, (2) spatially confined within Bouma’s window, and (3) feature specific. Here, we ...

No correlations between the strength of visual illusions

Michael Herzog, Fred Mast, Aaron Michael Clarke, Lukasz Grzeczkowski

In cognition, audition, and somatosensation, performance correlates strongly between different paradigms suggesting the existence of common factors. Surprisingly, this does not hold true for vision. For example, performance in line bisection and visual acu ...
