Supersaturation in the peripheral retina
Foveal and peripheral hue-scaling data were obtained fora I super(o) foveal stimulus and a 3[degrees] stimulus presented at 10[degrees] retinal eccentricity under both bleach (reducing rod input) and no-bleach (permitting rod input) conditions. Uniform appearance diagrams (UADs) were generated from...

description | Foveal and peripheral hue-scaling data were obtained fora I super(o) foveal stimulus and a 3[degrees] stimulus presented at 10[degrees] retinal eccentricity under both bleach (reducing rod input) and no-bleach (permitting rod input) conditions. Uniform appearance diagrams (UADs) were generated from the data. Peripheral stimuli appeared more saturated than foveal stimuli (i.e., supersaturated), especially in the green-yellow region of the UADs. This effect was particularly pronounced for the peripheral bleach condition. The range of wavelengths perceived as green-yellow in the peripheral retina was expanded as compared to the fovea, while the range of wavelengths experienced as blue-green was compressed. This indicates that there are shifts in the unique hue loci with retinal location. While several factors can be ruled out as potential causes for these perceptual differences, the underlying mechanism of this supersaturation effect in the peripheral retina is unknown. |
