Contrast-modulated (CM) gratings, composed of two luminance-modulated sinusoids of similar spatial frequency, mask the detection of test sinusoids at the difference frequency. However, the mechanism underlying masking by CM gratings remains poorly un... Read More about A binocular site for contrast-modulated masking.

Effects of glaucoma and aging on photopic and scotopic motion perception. (2000)
Journal Article
Willis, A., & Anderson, S. J. (2000). Effects of glaucoma and aging on photopic and scotopic motion perception. Investigative Ophthalmology & Visual Science, 41, 325-335

PURPOSE: To examine the effects of primary open-angle glaucoma and normal aging on visual sensitivity for targets known to bias responses from the magnocellular visual processing stream.

METHODS: Contrast sensitivity was measured for the detection... Read More about Effects of glaucoma and aging on photopic and scotopic motion perception..
