The chapter reviews methods of obtaining records that show signs of emotion. Concern with authenticity is central to the task. Converging lines of argument indicate that even sophisticated acting does not reproduce emotion as it appears in everyday action and interaction. Acting is the appropriate source for some kinds of material, and work on that topic is described. Methods that aim for complete naturalism are also described, and the problems associated with them are noted. Techniques for inducing emotion are considered under five headings: classical induction; physical induction; games; task settings; and conversational interactions. The ethical issues that affect area are outlined, and a framework for dealing with them is set out.
