Evidence for 40-Hz oscillatory short-term visual memory revealed by human reaction-time measurements
(American Psychological Association, 2000-05)
Four experiments show that presentation of a synchronous premask frame within a 40-Hz, flickering premask matrix primes subsequent detection of a Kanizsa-type square by generation of a 40-Hz prime. Reaction time (RT) priming ...
A moment to reflect upon perceptual synchrony
(MIT Press, 2006-10)
How does neuronal activity bring about the interpretation of visual space in terms of objects or complex perceptual events? If they group, simple visual features can bring about the integration of spikes from neurons ...
Modeling as part of perception: a hypothesis on the function of neural oscillations
(Pabst Science Publishers, 2001)
We argue that the effectiveness of synchronization of oscillatory neural activities coding
simple features, as it relates to perceptual organization, may originate in the temporal
characteristics of resonance that develops ...
The visual hallucinatory response to flickering polychromatic light.
(The International Society for Psychophysics, 2004)
Our understanding of human visual perception generally rests on the assumption that conscious visual states represent, in some qualitative fashion, a complex interaction between spatially structured variations in the ambient ...
Extended visual simultaneity thresholds in patients with schizophrenia
(Oxford University Press, 2009-07)
Clinical observations suggest that the experience of time phenomenology is disturbed in schizophrenia, possibly originating disorders in dynamic cognitive functions such as language or motor planning. We examined the ...
The computation of shape orientation in search for Kanizsa figures
(Pion Ltd, 2009-01-29)
Previous studies of visual search for illusory figures have provided equivocal results, with efficient search for Kanizsa squares (eg Davis and Driver, 1994 Nature 371 291-293) contrasting with inefficient search for Kanizsa ...
Effects of stimulus synchrony on mechanisms of perceptual organization
(Taylor & Francis, 2001-06-05)
When neurons adopt a synchronized, oscillatory response to stimulus Gestalten, the phase of those oscillations almost always varies relative to stimulus activity. This has been taken to indicate that form-coding mechanisms ...
Evidence for impaired integration-segmentation processes and slowed synchrony coding in dyslexics
(Pabst Science Publishers, 2001)
Using a primed figure-detection task we were able to reveal the existence of two distinct groups of dyslexics. One group is characterized by a significant impairment of visual integration-segmentation processes, resulting ...
Fechner's colors are induced by flickering monochromatic light
(Pabst Science Publishers, 2001)
Fechner described the phenomenon of inducing illusory colors by means of rotating blackand-
white disks. The induced spectral illusions were later termed "Fechner's colors". Similar
color perceptions can be induced by ...
