Very few exclusive percepts for contrast-modulated stimuli during binocular rivalry
Binocular rivalry properties for contrast-modulated (CM) gratings were examined to gain insight into their locus of processing. Two orthogonally orientated gratings were presented, one to each eye. Perceptual change rates, proportions of exclusivity and mixed percepts, and mean durations were calculated. Stimuli were noiseless luminance-defined (L), luminance-modulated noise (LM) and contrast-m...
متن کاملPreserved gain control for luminance contrast during binocular rivalry suppression
Binocular rivalry elevates contrast increment thresholds for the detection of a transient stimulus presented to the suppressed eye, while thresholds measured during dominance are identical to those during monocular viewing (e.g. [Wales, R., & Fox, R. (1970). Increment detection thresholds during binocular rivalry suppression. Perception and Psychophysics, 8, 90-94]). It is well established that...
متن کاملLateral facilitation revealed dichoptically for luminance-modulated and contrast-modulated stimuli
Foveal detection thresholds for LM and CM Gaussian blobs in the presence of visible, laterally placed blobs (separations of 0-6°) were measured monocularly and dichoptically in observers with normal vision. In the monocular and dichoptic viewing conditions, masking occurs for overlapping blobs, followed by facilitation when they are completely separated (2-8 blob sd units under monocular condit...
متن کاملLateral interactions across space reveal links between processing streams for luminance-modulated and contrast-modulated stimuli
Foveal detection thresholds for luminance-modulated (LM) and contrast-modulated (CM) blobs in the presence of fixed modulation, laterally placed noise blobs (separations of 0-6 degrees ) were measured in four observers with normal vision. Detection thresholds measured for LM blobs placed between highly visible LM flankers (111) and for CM blobs placed between highly visible CM flankers (222) pr...
متن کاملInvestigation of interocular blur suppression using luminance-modulated and contrast-modulated noise stimuli.
Presenting two sufficiently dissimilar images, one to each eye, may result in interocular suppression. The present study measured interocular suppression depth and extent in binocularly normal participants when blurring one eye only with varying dioptric lens powers (+0.5, +1, +2, and +4 D). Visual stimuli consisted of eight concentric rings of alternate polarity, divisible into eight sectors, ...
