This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book discusses the personal implications of reflectivity for the different parties in the research. It focuses on reflectivity from both the researchers’ and participants’ perspectives as well as from the interaction between them, as they pertain to the research process. The book describes the relationship that may develop between researchers, research participants and other stakeholders in the research process. It shows that common perspectives of the reflective process tend to represent such processes as procedures of discovering or rediscovering some “pre-existing” reality. The book demonstrates how applying a “sense of differentness” to the identification of ethical differences and similarities between researchers and participants may serve as the starting point for the production of knowledge through exploration and reflection, conflict, negotiation, and argumentation. It outlines research relationships from the perspective of status and power.
