Journal Article
Willis, A. & Anderson, S. J. (1999). Effects of glaucoma and aging on photopic and scotopic motion perception. Investigative Ophthalmology & Visual Science. 41. . 325-335. . ISSN 0146-0404.

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..

Comparing Contrast-Modulated and Luminance-Modulated Masking: Effects of Spatial Frequency and Phase (2000)
Journal Article
Willis, A., Smallman, H. S., & Harris, J. M. (2000). Comparing Contrast-Modulated and Luminance-Modulated Masking: Effects of Spatial Frequency and Phase. Perception, 29(1), 81-100. https://doi.org/10.1068/p2999

The masking of a sinusoidal test grating by contrast-modulated (CM) gratings could, in principle, be attributable to the presence of a distortion product, injected into the stimulus during some nonlinear transformation at an early level of visual pro...
