Understanding the promotion factors of the adaptive expertise

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.
