Abstract

This chapter describes a general approach to memory in the form of a model of memory called a "multiple-entry, modular memory system" (MEM). The model proposes that the multiple functions that memory serves are accomplished by several interacting but distinguishable subsystems. This model tries to resolve or clarify a number of issues—for example, the controversy between the trace and constructive theories of memory, the role of attention in establishing long-term memories, and the relations among various measures of memory. MEM provides a framework for generating new hypotheses about a number of other areas—for example, the relation between memory and emotion, the relation between specific autobiographical memories and general knowledge, and the problem of characterizing memory disorders. A malfunction in the reflection system would tend to result in a disconnection between memories and personal identity such as is found in amnesics. Different memory tasks draw differentially on different subsystems in MEM; hence, an entry not revealed by one memory task may be revealed by another.
