Recent theorisations of practice have suggested that a focus on the role of the body in professional practices, in simulated or naturalistic settings, might enable educators and learners to draw attention to other dimensions of knowledge, which are not easily accessible through cognitive perspectives. Recognising the role of the body in knowledge production in practice goes beyond a focus on the individual practitioner, in the clarification how the performance of a practice is constituted by the relational nature of material arrangements and professional bodies. This chapter re-visits dimensions of simulation from a specific focus of realism and embodiment and discusses the clinical impression of the manikin as multiple bodies being simulated—through doings and sayings bound together with materiality.
