The Influence of Rods on Colour Naming During Dark Adaptation

Show Summary Details

Preview

Various studies have demonstrated that the effects of rods on hue judgments depend on the size and intensity of the test stimulus. Studies have also shown increased rod influence with smaller stimuli than with larger stimuli. This chapter shows that the differences in hue perception between the fovea and 8° nasal retinal eccentricity may be minimized if either the size or intensity of the stimuli presented to the peripheral retina is increased.

Keywords: rods; hue judgments; visual stimuli; retina; peripheral perceptions
