Surgery is very cognitively demanding, particularly for novices. Novices are required to direct full attention on the procedure at hand, and additional demands can lead to cognitive overload. Through extensive practice, experts develop spare attentional capacity (SAC) for simultaneous tasks. However, little effort has been made to enhance novices' SAC. Mental skills may enhance attention management and increase SAC. The purpose of this study was to determine the efficacy of a novel mental skills curriculum (MSC) to enhance novices' attention management.
Sixty novice volunteers were randomly stratified to a control or MSC group based on baseline laparoscopic skill and mental skill use (assessed with the Test of Performance Strategies version 2 [TOPS-2]). All participants received laparoscopic training, whereas the MSC group received additional mental skills training. At all sessions, participants completed a secondary task during laparoscopy, which assessed SAC. Participants also completed the D2 Test of Attention and the TOPS-2 attention control subscale, which are valid attention measures.
Fifty-five novices completed the study. Both groups displayed significantly improved laparoscopic suturing ability (P < 0.001) and D2 performance (control: P < 0.005, MSC: P < 0.01), but there were no between-group differences in D2 or TOPS attention control scores. However, only the MSC group displayed significantly improved hit rate on the secondary task (P < 0.05).
The novel MSC implemented in this study enhanced surgical novices' SAC compared to controls, and it is clear that this curriculum may be effective at enhancing learners' ability to attend multiple task-relevant stimuli concurrently. Additional study of the impact of this MSC on learners' attentional capacity is currently underway.
手术对认知要求很高,尤其是对于新手而言。新手需要将全部注意力集中在手边的操作上,而额外的要求可能会导致认知过载。通过大量练习,专家们会发展出用于同时处理多项任务的备用注意力容量(SAC)。然而,在提高新手的SAC方面所做的努力很少。心理技能可能会增强注意力管理并增加SAC。本研究的目的是确定一种新型心理技能课程(MSC)在增强新手注意力管理方面的效果。
60名新手志愿者根据基线腹腔镜技能和心理技能使用情况(通过绩效策略测试第2版[TOPS - 2]进行评估)被随机分层到对照组或MSC组。所有参与者都接受了腹腔镜训练,而MSC组还接受了额外的心理技能训练。在所有课程中,参与者在腹腔镜检查期间完成一项次要任务,该任务评估SAC。参与者还完成了注意力D2测试和TOPS - 2注意力控制子量表,这是有效的注意力测量方法。
55名新手完成了研究。两组的腹腔镜缝合能力(P < 0.001)和D2测试表现(对照组:P < 0.005,MSC组:P < 0.01)均有显著提高,但在D2或TOPS注意力控制分数方面两组之间没有差异。然而,只有MSC组在次要任务上的命中率有显著提高(P < 0.05)。
与对照组相比,本研究中实施的新型MSC增强了外科新手的SAC,并且很明显该课程可能有效地提高学习者同时关注多个与任务相关刺激的能力。目前正在对该MSC对学习者注意力容量的影响进行进一步研究。
