Abstract
-
Consolidation is a fundamental process of memory formation that has traditionally been studied in two ways: retroactive interference (RI) and distributed learning (DL). Currently, however, there is seemingly no coherent theoretical framework within which to understand RI and DL data that have been collected over the last one hundred years. In this paper the argument is made that in order to make sense of the RI and the DL effects, memory cannot be treated as a single unified process. Rather, at least four types of memory systems must be examined separately: declarative implicit, declarative explicit, cognitive procedural, and motor procedural. In the first part of this paper each of these systems is explored, and the RI and DL effects for each of them is reviewed. It is argued that RI disrupts explicit declarative memories but not implicit declarative memories. Further, evidence for a RI time gradient has only been found for procedural memory. These findings are discussed within the framework of a strategic retrieval view of RI effects.;In the second part of the paper the differences in consolidation among cognitive procedural knowledge and motor procedural skill are examined empirically. The DL and the RI effects for both cognitive procedural and motor procedural knowledge are examined using the sequential reaction time task (SRT). It is found that the consolidation of cognitive procedural knowledge and motoric procedural knowledge differ in a number of ways: (a) the time course; (b) their resistance to interference; and (c) the rate of their improvement. The implications of these findings to the theory of consolidation are discussed from an evolutionary/computational perspective.
