Objective: High impulsiveness is associated with adverse outcomes, such as dangerous driving leading to traffic accidents and decreased job performance in general. In surgical training, high impulsiveness is associated with increased damage during simulated laparoscopic tasks. The objective of this study is to investigate the impact of professional experience on the relation between impulsiveness and simulated laparoscopy.

Surgical trainees show decreased performance during laparoscopic surgery when the laparoscope (camera) is not aligned with their line of sight towards the operating area. In this study we investigate the influence of visuospatial ability on laparoscopic simulator performance under such non-zero optical angles. Novices were invited to participate in a laparoscopic training session.

Background: Deviated optical angles create visuospatial and psychomotor challenges during laparoscopic procedures, resulting in delayed operative time and possibly adverse events. If it is possible to train the skills needed to work under these deviated optical angles, this could benefit procedure time and patient safety. This study investigates the influence of the optical angle on development of basic laparoscopic surgical skills.

Background: Adaptive training is an approach in which training variables change with the needs and traits of individual trainees. It has potential to mitigate the effect of personality traits such as impulsiveness on surgical performance. Selective performance feedback is one way to implement adaptive training.

Background: Little is known about the relation between impulsiveness and surgical performance even though research in similar high-risk/high-skills shows evidence of more hazardous behavior by impulsive professionals. We investigated the impact of impulsiveness on laparoscopic simulator performance.

Methods: Eighty-three subjects participated in a four-session laparoscopic training course.

Background: Creating and updating expert performance-based standards for simulators is labor intensive and requires the regular availability of expert surgeons. We investigated how peer performance based standards compare to expert performance based standards.

Methods: One hundred medical students took part in a four-session laparoscopic basic skills simulator training course.

Background: Surgical training is moving away from the operating room toward simulation-based skills training facilities. This has led to the development of proficiency-based training courses in which expert performance data are used for feedback and assessment. However, few expert value data sets have been published, and no standard method for generating expert values has been adopted by the field.

Objective: To answer 2 research questions: what are the learning curve patterns of novices on the da Vinci skills simulator parameters and what parameters are appropriate for criterion-based robotic training.

Materials And Methods: A total of 17 novices completed 2 simulator sessions within 3 days. Each training session consisted of a warming-up exercise, followed by 5 repetitions of the "ring and rail II" task.
