Background: The fulcrum effect of the body wall on instrument handling poses a major obstacle to the mastery of instrument coordination for junior laparoscopic surgeons. This study evaluated three types of laparoscopic simulator training to assess their ability to promote the user's adaptation to the fulcrum effect. Methods: Thirty-two participants with no(More)
OBJECTIVES To evaluate virtual reality as a laparoscopic training device in helping surgeons to automate to the "fulcrum effect" by comparing it to time-matched training programs using randomly alternating images (ie, y-axis inverted and normal laparoscopic) and normal laparoscopic viewing conditions. METHODS Twenty-four participants (16 females and 8(More)
BACKGROUND AND STUDY AIMS The aim of this study was to evaluate four training programmes intended to help laparoscopic surgeons automate to the "fulcrum effect". METHODS A total of 32 participants (16 men, 16 women), were randomly assigned to one of four different image-viewing conditions: full binocular, y-axis inverted, normal laparoscopic and randomly(More)
The present study focuses on the consequences of the social dynamics that are created whenever two or more individuals are brought together for the purpose of training. An investigation of the role of individual differences in interaction anxiety on training outcomes demonstrated that the comparative effectiveness of dyadic versus individual protocols for(More)
This study investigated training-team protocols, which Shebilske, Goettl, and Regian (in press) defined as protocols in which trainees practice a task in teams of two or more in order to achieve the goal of performing the task individually. The purpose of having teammates during practice is so that they can help each other achieve that goal. Shebilske,(More)
Employees of temporary agencies practiced Space Fortress, a complex video game task, for 10 sessions, each consisting of 8 practice and 2 test games of 3 min each. Trainees practiced individually, in dyads, or in tetrads, and they were classified as having high or low aptitude based on computer attitude scores and baseline performance. Competition for(More)
