Properties of episodic memories
Table 1 lists nine properties of episodic memories that collectively distinguish them from other types of memory representations. Note that, it is the combination of these features that are proposed as defining. Other types of long-term memory representations may feature one or several of the properties but only episodic memories have all nine properties. These properties are now considered in further detail, as are some of the issues they raise for the study of episodic memories.
The first
Organization of episodic memories
The idea that episodic memories are stored in memory in a way that preserves the temporal dimension was introduced above. But this temporal organization cannot be long-lasting, especially as access to so many initially formed episodic memories is lost within a few days of formation. Moreover, there is little evidence of the retention of detailed and specific temporal organization of episodic memories in long-term memory. Instead, the organization of those episodic memories access to which is
The development of episodic remembering
Episodic elements are formed outside conscious awareness and their formation is not within intentional control. One possibility is that hippocampal networks mediate the formation of episodic elements and their connection to a conceptual frame, although networks in other brains regions, fronto-temporal for example, may also influence the establishment of conceptual frames. An interesting question that then arises is: how can EEs be associated with conceptual frames in an infant's memory? One
Summary
I have presented a view of episodic memories that highlights their possible nature and functions. It is a view that proposes that episodic memories developmentally form the basis of the conceptual system in which they are embedded and which in turn they come to represent. The function of episodic memories is to provide a basis for the adaptive pursuit of short-term goals. Access to episodic memories is lost fairly quickly but if a memory or set of memories become integrated with the conceptual
