The power of odors to unlock human memory is celebrated in literature and anecdote, but poorly documented by science. Odors -- perhaps more than other stimuli -- are widely believed to evoke vivid and complex past experiences easily. Yet in contrast to the frequency with which odors are thought to evoke memories of the past, scientific evidence is thus far scant. For years, voluminous data have been collected on odor sensitivity, whereas relatively few studies exist on memory for odors per se. Moreover, the memory data that do exist are thus far only poorly integrated with the most modern attitudes on human memory. The major goal of this volume is to point the way toward a better state of affairs, one in which the study of odor memory is legitimatized as a proper specialization and is informed by the most promising ideas in the mainstream study of memory. This volume explores three tendencies in modern memory theory that have not yet sufficiently penetrated the odor-memory work: memory coding, memory and knowledge, and implicit and explicit memory.
