摘要

Background Long quiet eye (QE) duration is central to expertise in sports, while cognitive "slowing down" has been identified as a perceptual skill possessed by skilled surgeons. Eye-tracking evidence is lacking about the relationship of QE duration to slowing down in surgeons. The aim of this study was to examine QE duration, hand movement time (MT), fixation location, and fixation duration in highly experienced (HE) and less experienced (LE) surgeons. Methods A mobile eye tracker and camera recorded coupled gaze and hand movements. Performance was quantified by blinded review. Results HE surgeons were rated higher than LE surgeons but did not differ in operating time or MT. HE and LE surgeons differed in fixation duration on the ligament of Berry during phases 1 and 2 and QE duration on the recurrent laryngeal nerve in phase 2. Conclusions Long-duration fixation on the ligament of Berry and long-duration QE on the recurrent laryngeal nerve combined with no significant differences in MT provide empirical evidence that HE surgeons cognitively slow down more than LE surgeons during critical phases of the operation.
