Reinforcement reduces the size-latency phenomenon: A cost-benefit evaluation of saccade triggering by Vullings, Cécile, Harwood, Mark R, Madelain, Laurent

“…Saccadic latencies are known to change as a function of target eccentricity and size. Recently, it has been shown that latencies consistently change according…”

Adaptation of naturally paced saccades by Gray, Michael J, Blangero, Annabelle, Herman, James P, Wallman, Josh, Harwood, Mark R

Infant saccades are not slow by Garbutt, Siobhan, Harwood, Mark R, Harris, Christopher M

“…Saccadic eye movements are essential for redirecting the fovea at different visual targets. In adults and children saccades are remarkably stereotyped. Peak…”

Saccade latencies in an overlap paradigm when manipulating the stimuli timing, energy and transient changes by Vencato, Valentina, Harwood, Mark, Madelain, Laurent

“…Previous studies showed that a temporal overlapping of the fixation-target with the saccade-target onset induces a shift of saccade reaction time distributions…”
