The 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 کاملOnset of illusory figures attenuates change blindness.
We examined whether the onset of a new object defined by illusory contours is detected with greater frequency than offset when neither is associated with a unique sensory transient. Observers performed a "one-shot" change detection task in which offsetting or onsetting elements of high luminance contrast circles generated the appearance or disappearance of a Kanizsa figure. Presenting "illusory...
متن کاملIllusory Modification of Lightness in “Anomalous” Figures
Observers see a white triangle on the top of three black disks; the white triangle appears lighter, although it has the same luminance of the white background. Also squared or irregular “anomalous” figures can be created (Kanizsa & Gerbino, 1987). Several competing explanations have been put forward for the effect (Dumais, & Bradley, 1976; Coren, 1991; Ramachandran & Rogers-Ramachandran, 2005),...
متن کاملInfants see illusory motion in static figures.
We investigated illusory motion perception in 6-to-8-month-old infants using a static figure which produces strong illusory motion. In experiment 1 we prepared a control figure, which was physically similar to the illusory motion figure but which did not produce illusory motion. We presented the illusory figure and the control figure side-by-side, and measured infants' looking time at the targe...
متن کاملIllusory depth from moving subjective figures and neon colour spreading.
If a pattern of concentric circles, interrupted so as to produce the perception of a subjective bar extending from the centre to the periphery of the pattern, was slowly rotated in a plane perpendicular to the line of sight, observers reported seeing the bar slanted in depth and moving over complete and stationary concentric circles. When the interrupted concentric circles were completed by red...
