“…A strength of this study was the use of both the Paas and the NASA-TLX scales, considering that they each assess different components of the construct. The NASA-TLX assesses tasks with a major psychomotor component (7), while the Paas assesses predominantly cognitive tasks (8). Another strength of this study was the comparison of the different workshops as well as the determination of differences in cognitive load according to the route, considering that it is well known that previously acquired knowledge is a fundamental component of the intrinsic load (18,19).…”

Introduction: Cognitive load determines working memory ability to store and retain information in long-term memory, thus conditioning learning. Objective: To compare cognitive loads among different simulation activities, including anesthesia and surgery simulation workshops in medical students. Methods: Cross-sectional analytical observational study. Two cognitive load measurement scales (Paas and NASA-TLX) were given to the students after each simulation workshop. Comparisons were made based on the scores derived from the scales. Results: Relevant differences were found in terms of the mental effort assessed by means of the Paas scale, as relates to student rotation order in the airway management workshop, with a greater effort being found in the group that rotated initially in surgery (6.19 vs. 5.53; p = 0.029). The workshop with the highest associated rate of frustration was the airway management workshop. Higher scores were obtained for this workshop in all the items of the NASA-TLX scale, reflecting a higher cognitive load when compared to the others. Conclusion: It was not possible to determine whether higher scores in some of the activities were associated with the inherent difficulty of airway management or the specific workshop design. Consequently, further studies are required to distinguish between those components in order to improve the way learning activities are designed.

“…Each item is assessed using a 12 cm visual scale to obtain a score between zero and twenty. That score is then multiplied by five to obtain a final score between zero and one-hundred for each item (7). The student is asked to rate each of the items using a visual analogue scale.…”
