Enhanced visuomotor learning and generalization in expert surgeons.

Enhanced visuomotor learning and generalization in expert surgeons. Hum Mov Sci. 2020 Jun;71:102621 Authors: Hewitson CL, Crossley MJ, Kaplan DM Abstract Although human motor learning has been intensively studied for many decades, it remains unknown whether group differences are present in expert cohorts that must routinely cope with and learn new visuomotor mappings such as expert minimally invasive surgeons. We found that expert surgeons compensate for a visuomotor perturbation more rapidly than naive controls. Modelling indicates that these differences in expert behavioural performance reflects greater trial-to-trial retention, as opposed to greater trial-to-trial learning rate. We also found that surgeons generalize to novel reach directions more broadly than controls, a result which was subsequently confirmed by our modelling. In general, our findings show that minimally invasive surgeons exhibit enhanced visuomotor learning and spatial generalization. PMID: 32452438 [PubMed - in process]
