Training students to be able to imitate the symptoms of disease so that they may demonstrate them to others is an effective form of context shifting. It allows the students to shift from a written or spoken description of the disease to a physical interpretation of it for themselves which also entails more cognitive work than even seeing a particular patient with the problem and identifying it correctly. The need to mentally internalize the issue and then physically recreate it helps in the acquisition of the knowledge.
Role playing or putting oneself into the shoes of another is another good example of creating a mental shift in context.
Getting medical students to play out the symptoms of patients can help to diffuse their social discomfort in dealing with these patients.
If this practice were used on broader scales might it also help to normalize issues that patients face and dispel social stigma toward them?
