Effect of oculomotor posture on spatial judgement in golf putting

1 April 1986


This investigative study was designed to determine whether or not potential errors in spatial judgement associated with oculomotor posture (fixation disparity and/or heterophoria) have a consistent effect on golf putting errors. Although fixation disparity is not a new phenomenon in optometry, little research has been devoted to its effects on visually guided motor performance. Previous studies have shown that inducing changes in heterophoria causes errors in distance judgements; this study deals only with naturally occcuring fixaion disparity and heterophoria. In theory, fixation disparity misalignments will cause golfers to perceive the hole in a different position than that in which it is actually located. Results showed no relationship beween direction and/or magnitude of fixation disparity (or heterophoria) and putting error. A possible explanation for these results is that the subjects have learned to compensate for this perceptual error.
