A Statistical Approach to Visual Masking and Spatial Attention
… vicinity of each other, a phenomenon called visual masking. Visual masking has been extensively studied to understand the dynamics of information processing in the visual system. Visual spatial attention is also known to modulate information processing and transfer within the visual system. …

Examining Visual Masking in Target Aquisition Uning Two-dimensional Fourier Analysis Techniques
… see the structure of objects within an image or visual scene. For example, spatial vision underlies people's abilities to discriminate important objects (or so-called "targets") from less important "background" objects. Spatial vision capabilities, however, are not fixed or unaffected by the …

Intermediate Level Mechanisms Supporting Face Perception
… dissertation involves behavioral adaptation and masking experiments that provide evidence regarding whether face perception and concentric form-from-structure perception engage a common processing mechanism.</p><p>Despite faces being complex visual stimuli, humans are able to perceive and …

Visual attention in primates and for machines - neuronal mechanisms
Visual attention is an important cognitive concept for the daily life of humans, but still not fully understood. Due to this, it is also rarely utilized in computer vision systems. However, understanding visual attention is challenging as it has many and seemingly-different aspects, both at …

Ocular dominance and temporal dynamics in the venetian blind effect
<p>The visual system can use small disparities between the stimuli seen by each eye as a binocular cue for depth. Geometric disparities are the most commonly used cue for stereopsis, but disparities in contrast and luminance can also lead to the perception of depth and both can cancel perceived …

Looking through the crowded mask: investigating the effect of distractor number and position in object substitution masking
Object substitution masking (OSM) is a phenomenon wherein a surrounding mask (typically four dots) that onsets with a target but lingers after its offset significantly reduces target perceptibility. OSM was originally postulated to occur only when spatial attention was spread (Di Lollo et al., …

Getting a grip on Schizotypy: Elucidating dorsal stream deficits in Schizophrenia Spectrum Disorders
… are associated with disproportionate dorsal visual stream dysfunction, relative to ventral visual stream function. However, there remains a gap in our understanding of the neuropsychology and functional implications of this deficit. Notably, the balance of evidence implicating dorsal stream …
