Effects of glaucoma and aging on photopic and scotopic motion perception. (2000)
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..

Developing the behavioural rules for an agent-based model of pedestrian movement. (2000)
Presentation / Conference Contribution
Willis, A., Kukla, R., & Kerridge, J. (2000, September). Developing the behavioural rules for an agent-based model of pedestrian movement. Paper presented at 25th European Transport Congress

The PEDFLOW project aims to develop a realistic and flexible planning tool capable of simulating the effects of microscopic environmental layout on various aspects of pedestrian movement. Behavioural research can help establish realistic values for s... Read More about Developing the behavioural rules for an agent-based model of pedestrian movement..

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...
