Learning and memory are inextricably intertwined. The capacity for learning presupposes an ability to retain the knowledge acquired through experience, while memory stores the background knowledge against which new learning takes place. During the dark years of radical behaviorism, when the concept of memory was deemed too mentalistic to be a proper subject of scientific study, research on human memory took the form of research on verbal learning (Anderson, 2000; Schwartz & Reisberg, 1991).

Conscious recollection appears to be governed by seven principles: elaboration, organization, time‐dependency, cue‐dependency, encoding specificity, schematic processing, and reconstruction. However, these same principles may not apply to unconscious, or implicit, memory. Implicit memory is most commonly reflected in priming effects which occur in the absence of conscious recollection. Dissociations between explicit and implicit memory have been observed in patients suffering various sorts of brain damage, in other forms of amnesia, in behavioral performance of neurologically intact subjects, and in brain‐imaging studies (...) of memory. The most popular interpretation of these dissociations holds that explicit and implicit memory are mediated by separate and independent brain systems. However, there are also compelling interpretations in terms of dual processes operating on the contents of a single memory system. (shrink)
