Alcohol does not affect dark adaptation or luminance increment thresholds.
OBJECTIVE It has been proposed that alcohol might induce within the retina a state akin to dark adaptation. However, the evidence to support this proposal is quite indirect. Another possibility is that alcohol might affect retinal gain control rather than sensitivity. To investigate these proposals psychophysically, we measured dark adaptation functions and increment thresholds with the increme...
متن کاملInteractions between flicker thresholds and luminance pedestals
We investigated the interactions between flicker thresholds and luminance pedestals using threshold versus contrast (TvC) and method of constant stimuli paradigms. High amplitude luminance pedestals were found to elevate flicker thresholds, but low amplitude luminance pedestals were unable to reduce flicker thresholds. Luminance pedestals elevated flicker thresholds more at low temporal frequen...
متن کاملDynamics of adaptation at high luminances: adaptation is faster after luminance decrements than after luminance increments.
As is well known, dark adaptation in the human visual system is much slower than is recovery from darkness. We show that at high photopic luminances the situation is exactly opposite. First, we study detection thresholds for a small light flash, at various delays from decrement and increment steps in background luminance. Light adaptation is nearly complete within 100 ms after luminance decreme...
متن کاملEquivalent luminance contrast of red-green drifting stimuli: dependency on luminance-color interactions and on the psychophysical task.
The equivalent luminance contrast (EqLC) of red-green drifting stimuli was assessed by three independent methods. The first method [method (a)] consisted in adjusting the luminance contrast of a yellow, equichromatic stimulus to match the direction-discrimination performances that were obtained with a red-green, equiluminant stimulus. The second method [method (b)] was a replica of the standard...
متن کاملLow number of luminance levels in the luminance noise increases color discrimination thresholds estimated with pseudoisochromatic stimuli
In pseudoisochromatic stimuli the presence of spatial and luminance noise forces the subject to discriminate the target from the background solely on the basis of chromaticity difference. Color-blind subjects may show difficulty to identify the target due to the elimination of borders and brightness clues caused by the luminance and spatial noise. Few studies have fully described the features o...
