An emotional state impacts task performance and cognition. However, evidence of the effect of an induced emotional state on laparoscopic performance has not yet been documented. We investigated whether surgical residents in whom a positive emotion had been induced would produce a better laparoscopic task performance than residents in whom a negative emotional state had been induced.
This controlled laboratory study recruited a total of 53 junior surgical residents who were divided into 3 groups. Each group was required to watch 1 of 3 ten-minute videos designed to evoke a positive, neutral, or negative emotion before performing a laparoscopic cholecystectomy on a virtual simulation model. Task performances, as evaluated by a global assessment form and psychomotor metrics that included task time, errors, and path lengths, were compared between the 3 groups.
Video watching induced different emotions, as measured by a Visual Analog Scale on feelings. The task time was significantly shorter in the positive (13.7 ± 2.5 minutes) than in the neutrally (17.7 ± 3.9 minutes) and the negatively (18.5 ± 3.8 minutes) induced-emotion groups (P < 0.001).Participants in the positive emotion group completed a laparoscopic cholecystectomy with a significantly lower error rate (2 vs. 4 vs. 7, P = 0.036) and shorter right-handed path length (1089.6 ± 250.6 cm vs. 1287.2 ± 355.5 cm vs. 1410.3 ± 304.1 cm, P = 0.010) than the participants in the neutral and negative emotion groups.
A positive emotion can enhance a simulated laparoscopic task performance as assessed by task time and path length. The results indicate that we might improve surgical task performance by adjusting the surgeon's emotional state. We plan a future study that will continue to investigate whether positive emotions can facilitate skill learning.
情绪状态会影响任务表现和认知。然而，尚未有证据表明诱导的情绪状态对腹腔镜手术表现的影响。我们研究了诱导积极情绪的手术住院医师是否比诱导消极情绪的住院医师表现出更好的腹腔镜手术任务表现。
这项对照实验室研究共招募了 53 名初级外科住院医师，他们被分为 3 组。每组都需要观看 3 个 10 分钟的视频之一，这些视频旨在引发积极、中性或消极的情绪，然后在虚拟模拟模型上进行腹腔镜胆囊切除术。通过全球评估表和心理运动学指标（包括任务时间、错误和路径长度）比较 3 组之间的手术表现。
视频观看通过感觉的视觉模拟量表测量诱导出不同的情绪。积极情绪（13.7 ± 2.5 分钟）组的任务时间明显短于中性（17.7 ± 3.9 分钟）和消极（18.5 ± 3.8 分钟）情绪组（P < 0.001）。积极情绪组的参与者完成腹腔镜胆囊切除术的错误率明显较低（2 比 4 比 7，P = 0.036），右手路径长度明显较短（1089.6 ± 250.6 cm 比 1287.2 ± 355.5 cm 比 1410.3 ± 304.1 cm，P = 0.010）比中性和消极情绪组的参与者。
积极的情绪可以通过任务时间和路径长度来提高模拟腹腔镜手术的任务表现。结果表明，我们可以通过调整外科医生的情绪状态来提高手术任务表现。我们计划进行一项未来的研究，以继续研究积极情绪是否可以促进技能学习。
