Dichromatic color vision at high light levels: red/green discrimination using the blue-sensitive mechanism.


:Three red/green blind observers (dichromats) performed a wavelength discrimination task over a wide range of intensity levels. As expected, discrimination failed in the entire red/green spectral range at the low intensities typically used in wavelength discrimination experiments, but at very high intensities (at or above 10,000 td) discrimination was well maintained into the red/green range. The following experiments demonstrate that dichromats are able to utilize signals from the blue-sensitive cones (S-cones) to mediate color discrimination throughout the spectrum at high intensities, and they provide an estimate of S-cone sensitivity throughout the visible spectrum.

  • Previewing distractors reduces efficiency of visual processing at previewed locations.

    abstract::Visual marking refers to the phenomenon in which old items in a visual search are excluded from the search when new items appear in the visual field. Visual marking may result from inhibition of irrelevant information at the location of old items before new items appear. Moreover, sensitivity to increments in contrast...
