Originally published in 1982, this book brings together two areas of research previously studied in parallel, with little interaction (particularly in the US): normal memory processing and the amnesic syndrome. When trying to document the relationship between the two it became apparent that there was much crossover and duplication of effort in a number of areas: whether long-term memory and short-term memory truly represent independent storage systems, or are simply points on a continuum; trying to determine the primary locus of variables influencing the rate at which information is lost during retention; whether episodic memory and semantic memory represent two different storage systems, or are simply artifacts produced by different kinds of query to a single memory system and finally, whether visual and verbal memory are independent. It was written, following a meeting in 1979, by a small group of investigators, brought together to explore this commonality and to share data and theory, thus beginning the promise of a bright future of interdisciplinary interaction in memory research.
