Spatial integration in human smooth pursuit by Heinen, Stephen J, Watamaniuk, Scott N.J

“…When viewing a moving object, details may appear blurred if the object’s motion is not compensated for by the eyes. Smooth pursuit is a voluntary eye movement…”

Speed discrimination of motion-in-depth using binocular cues by Harris, J M, Watamaniuk, S N

“…Although it is well known that motion-in-depth can be detected using binocular cues, it is not known whether those cues can be used to judge the speed of an…”

Local motion detectors cannot account for the detectability of an extended trajectory in noise by Verghese, Preeti, Watamaniuk, Scott N.J, McKee, Suzanne P, Grzywacz, Norberto M

“…Previous work has shown that a single dot moving in a consistent direction is easily detected among noise dots in Brownian motion (Watamaniuk et al., (1995)…”

Detecting a trajectory embedded in random-direction motion noise by Watamaniuk, S N, McKee, S P, Grzywacz, N M

“…Human observers can easily detect a signal dot moving, in apparent motion, on a trajectory embedded in a background of random-direction motion noise. A high…”

A common mechanism modulates saccade timing during pursuit and fixation by Badler, Jeremy B, Watamaniuk, Scott N J, Heinen, Stephen J

“…Smooth pursuit is punctuated by catch-up saccades, which are thought to automatically correct sensory errors in retinal position and velocity. Recent studies…”

Choosing a foveal goal recruits the saccadic system during smooth pursuit by Heinen, Stephen J, Badler, Jeremy B, Watamaniuk, Scott N J

“…Models of smooth pursuit eye movements stabilize an object's retinal image, yet pursuit is peppered with small, destabilizing "catch-up" saccades. Catch-up…”

A foveal target increases catch-up saccade frequency during smooth pursuit by Heinen, Stephen J, Potapchuk, Elena, Watamaniuk, Scott N J

“…Images that move rapidly across the retina of the human eye blur because the retina has sluggish temporal dynamics. Voluntary smooth pursuit eye movements are…”

Illusory motion reveals velocity matching, not foveation, drives smooth pursuit of large objects by Ma, Zheng, Watamaniuk, Scott N J, Heinen, Stephen J

“…When small objects move in a scene, we keep them foveated with smooth pursuit eye movements. Although large objects such as people and animals are common, it…”
