Eye quietness

Question 1

electrooculogram (EOG)

Answer 1

high temporal resolution, distinguish phases of the mvt (Like pre and post mvt initiation), settings can be manipulated automatically, examine a signal as a function of time (eye quietness)

Question 2

Gallicchio et al.2018 golf putting

Answer 2

measured performance, putting times, quiet eye and eye quietness
results showed no difference in performance or addressing times, swing times longer for experts, an experts EOG trace is the same for each putt while a novice has variable QE duration across putts, experts had a longer QE duration post mvt

Question 3

Gallicchio et al 2018 QE duration findings

Answer 3

QE (total): under no threshold setting is experts’ QE longer than novices’ QE- for most settings experts have shorter QE (pre) and longer QE (post) than novices

Question 4

The QE post is associated with the

Answer 4

duration of the swing

Question 5

Problems with eye quietness (EQ)

Answer 5

different settings of EOG influence the durations of the QE and the eyes are never completely quiet

Question 6

advantage of eye quietness (EQ)

Answer 6

different approach, measures “quietness” within specific time intervals, no thresholds/algorithm issues, we can examine time dynamics

Question 7

Eye Quietness (EQ)

Answer 7

variability of the EOG within short intervals- greater variability= less EQ, smaller variability= more EQ - measured in uV as a function of time

Question 8

Gallicchio & Ring 2018 golf putting

Answer 8

measured EOG (QE, EQ), ECG (visual processing), kinematics sensors (mvt duration) - results showed longer QE for > threshold and EQ independent of threshold, inhibition of the occipital (visual) regions increases 2s preceding mvt initiation (due to increased alpha)- conclusion: QE not associated with visual processing but with mvt duration
