Abstract
Simulation-based education (SBE) has all the requisite elements for a stressful experience: being novel, unpredictable, imparting a sense of lack of control, and potentially threatening the participant’s ego. Indeed, SBE has been shown to evoke a physiological stress response in learners, which can be measured objectively using physiological or biological means, or subjectively using self-report questionnaires. The interaction between stress and cognitive load on performance and learning in the simulation environment is complex and not yet fully elucidated. At an appropriate level of cognitive load and moderate level of stress, simulation challenges and engages the learner, contributing to improved performance and learning outcomes. On the other hand, excessive stress can contribute to cognitive overload, attentional narrowing and distractibility, all of which are associated with impaired performance. Despite this detrimental effect of stress, learning can still be reinforced at high-stress levels through the enhancement on memory consolidation.
In the simulation arena, stress results not only from the scenario difficulty but also from emotions, noise, team dynamics, the presence of observers, and the subjective perception of being appraised. The learners’ perception of their abilities to meet the presented challenge will dictate their stress response and this in turn is likely influenced by prior experience in simulation, clinical expertise, perceived task difficulty, team factors, as well as their personality traits and coping styles. Several studies have reported that SBE could provide higher stress levels in trainees than those they may experience during real-life clinical situations. Simulation educators have traditionally embraced the potential benefits of adding realistic stress to simulation training. However, they should be equally cognizant of the potentially negative effects of stress on performance and consider strategies to minimize unnecessary stress.
