Do novices display automaticity during simulator training?
Department of Surgery, Carolinas Medical Center, Charlotte, NC, USA. BACKGROUND: The objective of this study was to investigate whether novices improve their ability to develop multitask (ie, automaticity) with accumulating experience on a simulated laparoscopic task. METHODS: In this prospective study, novices (12 premed students) trained for 4 months in laparoscopic suturing. Simultaneously with suturing, participants performed a visual-spatial secondary task to assess their spare attentional capacity. Trainees were required to achieve expert-derived levels in both suturing (520 score) and the secondary task (target 73%). Their performance was assessed with objective scores, and their ability to multitask during training was examined. RESULTS: After 10 +/- 5 hours and 84 +/- 41 repetitions, participants demonstrated improvements in their suturing (70%, P < 0.001) and secondary-task performance (16%, P = 0.08) compared with their baseline scores. During the study period, 11 of 12 part
