Assessing ocular activity during performance of motor skills using electrooculography 2018

This collection contains Quiet Eye (QE) duration (separating pre‐ and post-movement initiation components) and Eye Quietness (EQ) data as a function of time in a golf putting task. Movement duration was also measured using a combination of infrared and sound sensors. Twenty healthy adults participated in this study (10 expert golfers and 10 novices).<p>Research has revealed that, compared to novices, experts make longer ocular fixations on the target of an action when performing motor skills; that is, they have a longer quiet eye. Remarkably, the reason why a longer quiet eye aids movement has yet to be established. There is a need for interdisciplinary research and new measures to accelerate progress on the mechanistic understanding of the phenomenon.
Experts had longer postmovement initiation quiet eye compared to novices; however, total and premovement quiet eye durations did not differ between groups. Eye quietness was inversely correlated with quiet eye duration, and was greatest immediately after movement initiation. Importantly, movement duration correlated positively with postmovement initiation quiet eye and negatively with eye quietness shortly after movement initiation. This study demonstrates the utility of assessing ocular activity during performance of motor skills using EOG. Additionally, these findings provide evidence that expert–novice differences in ocular activity may reflect differences in the kinematics (e.g., movement duration) of how experts and novices execute motor skills.</p>
