Enhancing immersive presence has been shown to have influence on learning outcomes in virtual types of simulation. Scenario-based human patient simulation, a mixed reality form, may pose unique challenges for inducing the centricity of presence among participants in simulation. A model for enhancing the centricity of presence in scenario-based human patient simulation is presented here. The model represents a theoretical linkage among the interaction of pedagogical, individual, and group factors that influence the centricity of presence among participants in simulation. Presence may have an important influence on the learning experiences and learning outcomes in scenario-based high fidelity human patient simulation. This report is a follow-up to an article published in 2014 by the author where connections were made to the theoretical basis of presence as articulated by nurse scholars.
