Metacontrast masking and the cortical representation of surface color： dynamical aspects of edge integration and contrast gain control
edge integration brightness lightness achromatic color brightness induction masking metacontrast paracontrast type B masking
2009/5/5
This paper reviews recent theoretical and experimental work supporting the idea that brightness is computed in a series of neural stages involving edge integration and contrast gain control. It is pro...
Visual masking by transcranial magnetic stimulation in the first 80 milliseconds
visual cortex masking feedforward re-entrant magnetic stimulation
2009/5/5
Stimulation of the occipital cortex with transcranial magnetic stimulation (TMS) can interfere with visual processing and may cause masking comparable to visual masking. The effect is most pronounced...
Spatio-temporal low-level neural networks account for visual masking
temporal processing visual masking spatio-temporal interactions temporal masking visual evoked potentials psychophysics
2009/5/5
Temporal masking is a paradigm that is widely used to study visual information processing. When a mask is presented, typically within less than 100 msec before or after the target, the response to the...
The role of feedback in visual masking and visual processing
visual masking feedback humans monkeys metacontrast paracontrast electrophysiology optical imaging fMRI psychophysics vision awareness attention consciousness standing wave
2009/5/5
This paper reviews the potential role of feedback in visual masking, for and against. Our analysis reveals constraints for feedback mechanisms that limit their potential role in visual masking, and in...
Grouping based feature attribution in metacontrast masking
metacontrast masking feature attribution feature integration motion grouping attention
2009/5/5
The visibility of a target can be strongly suppressed by metacontrast masking. Still, some features of the target can be perceived within the mask. Usually, these rare cases of feature mis-localizatio...
In modeling visual backward masking, the focus has been on temporal effects. More specifically, an explanation has been sought as to why strongest masking can occur when the mask is delayed with respe...
Spatial processing and visual backward masking
temporal processing verniers unmasking metacontrast
2009/5/5
Most theories of visual masking focus primarily on the temporal aspects of visual information processing, strongly neglecting spatial factors. In recent years, however, we have shown that this positio...
A theory of moving form perception: Synergy between masking, perceptual grouping, and motion computation in retinotopic and non-retinotopic representations
moving form perception dynamic form perception visual masking perceptual grouping motion
2009/5/5
Because object and self-motion are ubiquitous in natural viewing conditions, understanding how the human visual system achieves a relatively clear perception for moving objects is a fundamental proble...
An analysis of visual masking, with a defense of “Stopped Processing”
masking metacontrast stopped processing
2009/5/5
The use of a backward mask (a patterned mask which follows the target in time) to "stop the processing" of the target illustrates an important application of masking - the study of the "microgenesis" ...
Common-onset masking simulated with a distributed-code model
masking metacontrast lateral inhibition mathematical model object substitution common-onset masking backward masking attention
2009/5/5
A distributed-coding model incorporating lateral inhibition in a simulated nerve network has been successful in accounting for many properties of backward masking (Bridgeman, 1971, 1978), linking mode...
What should a quantitative model of masking look like and why would we want it?
backward masking dynamic vision modeling
2009/5/5
Quantitative models of backward masking appeared almost as soon as computing technology was available to simulate them; and continued interest in masking has lead to the development of new models. Des...
Visual masking：past accomplishments, present status, future developments
masking neural networks nonconscious/conscious processing object perception
2009/5/5
Visual masking, throughout its history, has been used as an investigative tool in exploring the temporal dynamics of visual perception, beginning with retinal processes and ending in cortical processe...
Visual masking and the dynamics of human perception, cognition, and consciousness. A century of progress, a contemporary synthesis, and future directions
vision motor control masking subliminal priming consciousness attention
2009/5/5
The 1990s, the "decade of the brain", witnessed major advances in the study of visual perception, cognition, and consciousness. Impressive techniques in neurophysiology, neuroanatomy, neuropsychology,...
Investigating neurophysiological correlates of metacontrast masking with magnetoencephalography
Metacontrast masking MEG object visibility working memory
2009/4/28
Early components of visual evoked potentials (VEP) in EEG seem to be unaffected by target visibility in visual masking studies. Bridgeman's reanalysis of Jeffreys and Musselwhite's (1986) data suggest...
