术中应激源的研究主要集中在外部因素上，没有考虑个体应对应激能力的差异。与压力对表现的不利影响有关的一个个体差异是“再投资”，即有意识地监视和控制动作的倾向。本研究的目的是检查在时间压力下再投资对腹腔镜性能的影响。将31名医科学生（外科轮作）分为再投资高组和再投资低组。参与者首先接受peg转移任务的熟练训练，然后在控制和时间压力条件下对同一任务进行测试。结果度量包括一般性能和过程度量。使用心率和状态-特质焦虑量表（STAI）评估压力水平。高和低再投资者表现出从控制到时间压力条件下的焦虑水平增加，这是他们的STAI分数所显示的，尽管心率没有发现差异。低再投资者在时间压力下的表现明显更快，而高再投资者在表现时间上没有变化。低再投资者倾向于比高再投资者表现出更高的绩效效率（更短的路径长度，更少的手部运动）。训练有素的医学生在有意识地监测和控制自己的动作方面具有较高的个人倾向（高再投资者），在腹腔镜任务中表现出较低的能力（比低再投资者）来满足时间压力的要求。这一发现表明，在时间压力下，再投资倾向可能对腹腔镜手术的表现有调节作用。
Research on intraoperative stressors has focused on external factors without considering individual differences in the ability to cope with stress. One individual difference that is implicated in adverse effects of stress on performance is “reinvestment,” the propensity for conscious monitoring and control of movements. The aim of this study was to examine the impact of reinvestment on laparoscopic performance under time pressure. Thirty-one medical students (surgery rotation) were divided into high- and low-reinvestment groups. Participants were first trained to proficiency on a peg transfer task and then tested on the same task in a control and time pressure condition. Outcome measures included generic performance and process measures. Stress levels were assessed using heart rate and the State Trait Anxiety Inventory (STAI). High and low reinvestors demonstrated increased anxiety levels from control to time pressure conditions as indicated by their STAI scores, although no differences in heart rate were found. Low reinvestors performed significantly faster when under time pressure, whereas high reinvestors showed no change in performance times. Low reinvestors tended to display greater performance efficiency (shorter path lengths, fewer hand movements) than high reinvestors. Trained medical students with a high individual propensity to consciously monitor and control their movements (high reinvestors) displayed less capability (than low reinvestors) to meet the demands imposed by time pressure during a laparoscopic task. The finding implies that the propensity for reinvestment may have a moderating effect on laparoscopic performance under time pressure.
