The perceived direction of motion of a brief visual stimulus that contains fine features reverses if static coarser features are added to it. Here we show that the reversal in perceived direction disappears if the stimulus is reduced in size fro[...]texto impreso
Chacón Gómez, José ; Castellanos López, Miguel Ángel ; Serrano Pedraza, Ignacio | Scholar One | 2015-12-01Previous research has shown a visual asymmetry in shaded stimuli where the perceived contrast depended on the polarity of their dark and light areas (Chacón, 2004). In particular, circles filled out with a top-dark luminance ramp were perceived [...]texto impreso
Serrano Pedraza, Ignacio ; Gamonoso Cruz, María J ; Sierra Vázquez, Vicente ; Derrington, Andrew M | Scholar One | 2013Our ability to discriminate motion direction in a Gabor patch diminishes with increasing size and contrast, indicating surround suppression. Discrimination is also impaired by a static low-spatial-frequency patch added to the moving stimulus, su[...]texto impreso
Read, Jenny C A ; Georgiou, Renos ; Brash, Claire ; Yazdani, Partow ; Whittaker, Roger ; Trevelyan, Andrew J ; Serrano Pedraza, Ignacio | Scholar One | 2015A well-studied paradox of motion perception is that, in order to correctly judge direction in high-contrast stimuli, subjects need to observe motion for longer in large stimuli than in small stimuli. This effect is one of several perceptual effe[...]texto impreso
The contrast detection threshold of a grating located in the periphery is increased if a surrounding grating of the same frequency and orientation is present. This inhibition between center and surround has been termed surround suppression. In t[...]texto impreso
Stereo vision has a well-known anisotropy: At low frequencies, horizontally oriented sinusoidal depth corrugations are easier to detect than vertically oriented corrugations (both defined by horizontal disparities). Previously, Serrano-Pedraza a[...]texto impreso
Yazdani, Partow ; Serrano-Pedraza, Ignacio ; Whittaker, Roger G ; Trevelyan, Andrew ; Read, Jenny C A | Scholar One | 2015Psychophysical surround suppression is believed to reflect inhibitory neuronal mechanisms in visual cortex. In recent years, two psychophysical measures of surround suppression have been much studied: (i) duration thresholds on a motion-discrimi[...]
