How do attending physicians describe cognitive overload among their workplace learners?

Cognitive load theory (CLT) focuses on the limited bandwidth of working memory. Core to CLT is the concept of cognitive overload, which occurs when working memory demands exceed working memory capacity, and learning and performance suffer. Within health professions education (HPE), workplace learning settings are very complex, placing learners at high risk of cognitive overload. Although continuous monitoring of physiologic parameters can indicate states of high cognitive load, how to practically identify cognitively overloaded learners within everyday workplace settings is not well understood. We sought to characterise how attending physicians described their perceiving of cognitive overload among learners in two different workplace settings: the gastrointestinal endoscopy suite and the intensive care unit.
