Decrease in illusory contour completion with retinal eccentricity is not due to loss of phase information.

Abrupt learning and retinal size specificity in illusory-contour perception
BACKGROUND In behavioral studies of learning, a distinction is commonly made between gradual and abrupt improvements in performance. The learning of perceptual and motor skills is often characterized by gradual, incremental improvement, and is found not to generalize over stimulus manipulations such as changes in the size or location of the retinal image. In contrast, marked improvement in perf...
متن کاملLittle loss of information due to unknown phase: redux
TheHapCluster algorithmsearches for the locationof avariant affectingdisease status by trying to identify flexible clusters of case haplotypes in the vicinity of a mutant allele. Rather than explicitly modelling the genealogy of the sample, the algorithm uses a locus-dependent distance measure between haplotypesequences to identify a cluster of sequences close to the “ancestor sequence” where t...
متن کاملIllusory contour strength does not depend on the dynamics or relative phase of the inducers
We use a new objective measure of illusory contour strength, threshold reduction for aspect ratio discrimination, to examine the effect of dynamics and relative phase on the Kanizsa illusion. We found no dependence of illusory contour strength on the relative phase of flickering inducers (in phase, antiphase, or in quadrature phase) either for the standard Kanizsa square, or for modifications t...
متن کاملIndependence of the completion effect from the noncompletion effect in illusory contour perception.
Spatially separated object information can be effortlessly completed in the visual system, as demonstrated by the well-known Kanizsa-type illusory contours. The perception of illusory contours is closely associated with the spatial configuration of contour fragments, leading to the long-lasting difficulty in distinguishing the effect of the completion process that interpolates the contour fragm...
متن کاملIllusory contour perception and amodal boundary completion: evidence of a dissociation following callosotomy.
A fundamental problem in form perception is how the visual system can link together spatially separated contour fragments to form the percept of a unitary shape. Illusory contours and amodal completion are two phenomena that demonstrate this linking process. In the present study we investigate these phenomena in the divided hemispheres of two callosotomy ("split-brain") patients. The data sugge...
