The role of motion parallax in the perception of egocentric direction (2017)
Presentation / Conference
Clark, K., & Rushton, S. K. (2017, May). The role of motion parallax in the perception of egocentric direction

Prisms optically rotate the visual scene relative to the head, but the error in perceived direction that results is less than the optical deflection of the prism. This is known as the immediate correction effect (Rock, Goldberg, & Mack, 1966). The ef... Read More about The role of motion parallax in the perception of egocentric direction.

Visually-induced vertigo (‘visual vertigo’) is a condition where certain visual environments trigger dizziness and nausea. It is often attributed to dysfunction in visual-vestibular interaction, but the exact cause is unknown. We were interested in a...

Global motion influences the detection of motion-in-depth (2016)
Presentation / Conference
Clark, K., & Rushton, S. K. (2016, September). Global motion influences the detection of motion-in-depth. Poster presented at European Conference on Visual Perception

Detecting motion-in-depth is more difficult than detecting equivalent lateral motion (e.g. Tyler, 1971). Because there is an early averaging of left and right motion signals, some work suggests the two monocular signals could effectively cancel out w...

Man vs. Mouse: The act of walking does not alter spatial suppression in humans (2015)
Presentation / Conference
Clark, K., & Rushton, S. K. (2015, May). Man vs. Mouse: The act of walking does not alter spatial suppression in humans

Recently, Ayaz et al. (2013) reported a remarkable finding: surround suppression, as measured by V1 activation in mice, is substantially reduced during locomotion (running in place).
