Multiple mechanisms of illusory contour perception.
A variety of mechanisms have been proposed to explain illusory contour formation. However, since prior studies have focused on a single mechanism, there is no clear consensus regarding contour formation mechanisms. Here we developed a novel vivid dynamic display we call the chomping pacman that allows measurement of minute differences in contour clarity. This illusion is shown to be more vivid ...
متن کاملAbrupt 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 کاملThe Shape of Illusory Figures
We have been developing a stochastic model for figure-ground separation[9][3][12]. The model selects/constructs the foreground with preference for figures with “more convex” shapes. When these models are applied to illusory figures ([7]) they yield perceptually accurate selection of figure and background. The approach is based on an “entropy” measure of a region dijfksion Markov model from a se...
متن کاملDoes contour classification precede contour grouping in perception of partially visible figures?
When a figure is only partially visible and its contours represent a small fraction of total image contours (as when there is much background clutter), a fast contour classification mechanism may filter non-figure contours in order to restrict the size of the input to subsequent contour grouping mechanisms. The results of two psychophysical experiments suggest that the human visual system can c...
متن کاملIllusory contour figures are perceived as occluding contours by 4-month-old infants.
Although 4-month-olds perceive continuity of an object's trajectory through occlusion, little is known about the information specifying an occluding surface at this age. We investigated this in 3 experiments involving 84 participants. Testing the claim that 5-month-olds are unable to perceive the Kanizsa figure as an occluding surface (Csibra, 2001), we demonstrated that 4-month-olds perceived ...
