Fifteen medical students performed a standard training task using the da Vinci Surgical robot's 2d and 3d viewing conditions. Measures of mental workload associated with both viewing conditions were assessed using a secondary interval production task as well as the NASA Task Load Index (NASA-TLX) and the Multiple Resources Questionnaire (MRQ). The Results of the NASA-TLX indicated that the 3d viewing condition results in lower scores of mental workload when compared to the 2d condition. The MRQ data provided diagnostic information regarding which information processing pools were stressed in both the 2d and 3d viewing conditions.
