Is there a common factor for vision?

Aims/Purpose: Eye diseases are implicitly assumed to affect vision generally. However, only visual acuity and contrast sensitivity are usually measured to determine perceptual deficits. What about orientation and motion perception? Methods: To address th ...

To what extend cataract surgery changes perceptual functions?

Michael Herzog, Simona Adele Garobbio

Aims/Purpose: Cataract, i.e., an opacification of the natural intraocular lens, is one of the leading causes of visual impairments worldwide. Cataract surgery, which involves the removal of the opaque lens and implantation of an artificial intraocular lens ...

To what extent do EEG measures reflect performance in perceptual tests?

Michael Herzog, Simona Adele Garobbio, Wei-Hsiang Lin

In many studies, EEG measures reflect performance in visual and cognitive tests, as determined by averages across different conditions or groups of participants. Based on these results, one might expect that there is also a significant correlation between ...

To what extent do cataracts and cataract surgery change perception?

Michael Herzog, Simona Adele Garobbio

Cataract surgery is the most commonly performed surgical procedure worldwide and is typically associated with an improvement in visual acuity (VA). This study aimed to examine how various visual functions, beyond VA and contrast sensitivity, are affected b ...

Bistable Perception Discriminates Between Depressive Patients, Controls, Schizophrenia Patients, and Their Siblings

Michael Herzog, Simona Adele Garobbio, Maya Roinishvili

Background and Hypothesis Individuals with schizophrenia have less priors than controls, meaning they rely less upon their prior experiences to interpret the current stimuli. These differences in priors are expected to show as higher alternation rates in b ...

Weak correlations between visual abilities in healthy older adults, despite long-term performance stability

Michael Herzog, Simona Adele Garobbio

Using batteries of visual tests, most studies have found that there are only weak correlations between the performance levels of the tests. Factor analysis has confirmed these results. This means that a participant excelling in one test may rank low in ano ...

Diving into the heterogeneity of the visual system

Simona Adele Garobbio

Using batteries of visual tests, most studies have found that there are only weak correlations between performance levels of tests in healthy young adults. Factor analysis has confirmed these results. This means that a participant excelling in one test may ...

Understanding visual perception in visual snow syndrome: a battery of psychophysical tests plus the 30-day clinical diary

Michael Herzog, Simona Adele Garobbio

Patients with visual snow syndrome (VSS) experience uncountable flickering tiny dots in the entire visual field. Symptoms often persist over the years. Very little is known about altered perception in VSS. VSS is diagnosed based on subjective reports becau ...

No Common Factor Underlying Decline of Visual Abilities in Mild Cognitive Impairment

Michael Herzog, Simona Adele Garobbio

Introduction Recent work has shown an association between cognitive and visual impairments and two main theories were advanced, namely the sensory deprivation and the common cause theories. Most studies considered only basic visual functions such as visual ...

Evaluating contrast sensitivity in early and intermediate age-related Macular Degeneration with the Quick Contrast Sensitivity Function

Michael Herzog, Simona Adele Garobbio

Purpose: The purpose of this study was to describe, validate, and compare the contrast sensitivity functions (CSFs) acquired with the novel quick CSF (qCSF) method from patients with early and intermediate age-related macular degeneration (eAMD and iAMD) a ...
