Identifying personality factors that account for individual differences in surgical training and performance has practical implications for surgical education. Movement-specific reinvestment is a potentially relevant personality factor that has a moderating effect on laparoscopic performance under time pressure. Movement-specific reinvestment has 2 dimensions, which represent an individual's propensity to consciously control movements (conscious motor processing) or to consciously monitor their 'style' of movement (movement self-consciousness).
This study aimed at investigating the moderating effects of the 2 dimensions of movement-specific reinvestment in the learning and updating (cross-handed technique) of laparoscopic skills.
Medical students completed the Movement-Specific Reinvestment Scale, a psychometric assessment tool that evaluates the conscious motor processing and movement self-consciousness dimensions of movement-specific reinvestment. They were then trained to a criterion level of proficiency on a fundamental laparoscopic skills task and were tested on a novel cross-handed technique. Completion times were recorded for early-learning, late-learning, and cross-handed trials.
Propensity for movement self-consciousness but not conscious motor processing was a significant predictor of task completion times both early (p = 0.036) and late (p = 0.002) in learning, but completion times during the cross-handed trials were predicted by the propensity for conscious motor processing (p = 0.04) rather than movement self-consciousness (p = 0.21).
Higher propensity for movement self-consciousness is associated with slower performance times on novel and well-practiced laparoscopic tasks. For complex surgical techniques, however, conscious motor processing plays a more influential role in performance than movement self-consciousness. The findings imply that these 2 dimensions of movement-specific reinvestment have a differential influence in the learning and updating of laparoscopic skills.
识别导致外科培训和表现存在个体差异的人格因素对外科教育具有实际意义。特定运动再投资是一个潜在相关的人格因素，在时间压力下对腹腔镜操作表现具有调节作用。特定运动再投资有两个维度，分别代表个体有意识控制动作的倾向（有意识运动加工）或有意识监测其运动“风格”的倾向（运动自我意识）。
本研究旨在调查特定运动再投资的两个维度在腹腔镜技能学习和更新（交叉手法技术）中的调节作用。
医学生完成特定运动再投资量表，这是一种心理测量评估工具，用于评估特定运动再投资的有意识运动加工和运动自我意识维度。然后他们在一项基本腹腔镜技能任务上接受训练，直至达到熟练标准水平，并接受一项新颖的交叉手法技术测试。记录早期学习、后期学习和交叉手法试验的完成时间。
运动自我意识倾向而非有意识运动加工是学习早期（p = 0.036）和后期（p = 0.002）任务完成时间的显著预测因素，但交叉手法试验期间的完成时间由有意识运动加工倾向（p = 0.04）而非运动自我意识（p = 0.21）预测。
较高的运动自我意识倾向与新颖和熟练的腹腔镜任务中较慢的表现时间相关。然而，对于复杂的外科技术，有意识运动加工在表现中比运动自我意识发挥更有影响力的作用。研究结果表明，特定运动再投资的这两个维度在腹腔镜技能学习和更新中具有不同的影响。
