Spatial structure of the frequency doubling illusion
We sought to determine (1) the perceived spatial frequency of flickering sinusoidal gratings as a function of temporal frequency at contrasts down to detection threshold levels, and (2) the influence of two different matching criteria on reported size matches to identify changes in the apparent spatial structure introduced by counterphase flicker. To determine if spatial structure was observabl...
متن کاملSpatial context affects the Poggendorff illusion.
The Poggendorff illusion has often been explained as purely an interaction between the parallels and the transversals. The present study demonstrates that additional spatial context exerts an influence on this illusion. In Experiment 1, we examined the effects of a surrounding tilted frame (complete and degraded versions) on collinearity adjustments in the upright and rotated Poggendorff figure...
متن کاملLow-spatial-frequency channels and the spatial frequency-doubling illusion.
PURPOSE This study examined the number and nature of spatiotemporal channels in the region where the frequency-doubling (FD) illusion would be expected to occur at eight locations spanning the central 30 degrees of the visual field. METHODS The probability of seeing the FD illusion was examined in 17 subjects. Stimuli were presented at 5 octaves of low spatial frequencies, at each of seven fl...
متن کاملThe spacing illusion: a spatial aperture problem?
A geometrical illusion in which the horizontal spacing between adjacent parallel lines in a row is underestimated when the lines are tilted away from vertical in a chevron configuration was investigated in two experiments. The perceived spacing was found to decrease as the tilt angle increased, consistent with the idea that separation judgements are influenced by the normal spacing between line...
متن کاملA Model of Representing Extension and Shrinking for Spatial Relations
Aiming at region connection calculus (RCC) can only roughly represent spatial topological relations, and have difficulty in representing the distance, direction and so on. Therefore, based on RCC theory, Region Extension and Shrinking Calculus are proposed, and then a formalized metrization method using region as a basic unit is introduced. Based on RESC theory, taking the advantage such as app...
