The contrasting impact of global and local object attributes on Kanizsa figure detection
(Psychonomic Society, 2007-11)
Studies on the involvement of object completions in search for illusory figures have so far reported equivocal results. We have addressed this issue by investigating at which level object attributes in Kanizsa figures ...
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 ...
The loci of oscillatory visual-object priming: a combined electroencephalographic and reaction-time study
(Elsevier, 2000-12)
The detection of reaction-times (RTs) to a target Kanizsa-type square (an illusory square defined by the collinear arrangement of 90° corner junctions) within a matrix of distractor junctions are expedited when the target ...
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 ...
