Understanding the promotion factors of the adaptive expertise

这项研究的目的是确定适应性专业知识背后的三个因素：1)掌握亚技能的过程；2)获得足够解决问题所需的知识；3)制定适当的自我评估标准。本研究使用神经外科训练模拟器，专注于夹闭脑动脉瘤的任务。研究对象为4名神经外科医生和6名医学生。受试者在锻炼过程中的表现是通过双手控制设备移动的轨迹、操作所需的时间、与正常大脑的接触程度以及产生的脑电来衡量的。虽然神经外科医生进行练习的时间波动很小，但学生之间存在相当大的差异。在手术过程中，学生们与正常大脑的接触率更高，但两组之间没有统计学上的显著差异。

The purpose of this research is to identify the three factors behind adaptive expertise: 1) the process of mastery of subskills; 2) acquisition of knowledge needed for adequate problem-solving; and 3) development of appropriate standards for self-appraisal.This research used a neurosurgical training simulator and focused on the task of clipping a cerebral aneurysm. The subjects were 4 neurosurgeons and 6 medical students. Subjects' performance during the exercise was measured in terms of the trajectory in which control devices in both hands were moved, the time the operation took to perform, the degree of contact made with the normal brain, and the EEG produced. While there was little fluctuation in the time it took for the neurosurgeons to perform the exercise, there was considerable disparity among the students. The students showed greater rates of contact with the normal brain during the procedure, but there was no statistically significant difference between the two groups.
