ABSTRACT
The concept of perceptual memory refers to the neural and cognitive processes underlying the storage of sensory information along such basic stimulus dimensions as spatial frequency, orientation, and motion (Magnussen, 2000; Magnussen & Greenlee, 1999). The concept is related to, but not identical with, the concept of visual working memory (Baddeley, 2003). In perceptual memory experiments, memory is assessed in terms of the precision by which stimulus information is retained in memory, rather than in terms of the number of visual items or categories that can be retained; with a research strategy, that is closer to the correspondence metaphor of memory than it is to the storehouse metaphor (Koriat, Goldsmith, & Pansky, 2000).
