The goal of the present study was to compare two secondary workload tasks, specifically a time interval estimation and visual-spatial task, to determine which of these is most appropriate for the assessment of laparoscopic mental workload. Participants performed a peg transfer task in two conditions: a normal camera angle and a 90° camera angle intended to increase mental workload. Based on multiple resource theory, it was predicted the visual-spatial task would be more sensitive to the workload manipulation than the time estimation task because it draws upon the specific, as opposed to more general, attentional resources required by laparoscopy.
