Cognitive Load and Stress Assessment of Medical High-Fidelity Simulations for Emergency Management

Abstract

High-fidelity medical simulations refer to the use of computerized mannequins that simulate real-life scenarios. It is important to avoid stress and cognitive overload of students in order to ensure a productive learning. This study concerns the identification and assessment of events related to intrinsic cognitive loads (ICL), extraneous cognitive loads (ECL) and stress episodes through the analysis of physiological parameters. 170 students were enrolled in the study. Analysed heart rate (HR) and electrodermal activity (EDA) were acquired through Empatica E4 wristband. Cognitive load assessment was performed by evaluating peaks in HR, associable with ICL or ECL through video analysis. The stressful events were assessed considering EDA in relation to HR, according to Russell’s circumplex plan. Results show good achievements in students’ performance and an ICL increment and an ECL decrement during simulation repetition. The stressful conditions increase with the increasing difficulty of the simulations.
