Elements of Episodic Memory was a seminal text in the memory literature, highly cited and influential. It has been unavailable for some years, but is now back in print as in its original form, with this reissue. The book examines the critical role that retrieval processes play in remembering. It proposes that the nature of recollective experience is determined by the interaction between the 'episodic' trace information and the 'semantic' retrieval information. This basic theme is elaborated by tracing the development of the ideas considering relevant empirical evidence, relating a proposed theoretical framework to the ideas held by other theorists, and dealing with criticisms advanced by others. These issues are discussed from two perspectives. Firstly, from the point of view of 'detached science': the emphasis here is on ideas, hypotheses, evidence, logic and theory. The second is a personal commentary on the development of ideas at the first viewpoint, and provides observations about the psychology and sociology of a developing science.
