Much like a computer, the human brain may retain traces of information even after being deleted. These memory traces are physico-chemical manifestations of representations (memories) in the brain. While their existence remains disputed, how might the existence of memory traces bear on developing new procedural and declarative memories? Why is this significant for understanding human cognition? 

 

When we store information into long-term memory if it is not recall and use regularly, much of the information is less available for later retrieval as time passes; memory and memory strength fade away. There are several theories on why we loose memory over time. One is displacement theory, which is the displacement of information in short-term memory due to limited storing capacity. When declarative memory information is first learned and rehearsed it goes into long-term memory, however information that is learned later and not rehearsed is likely to be forgotten because it is displaced by new information that is in the rehearsal process.  Memory trace represent limited information from the pass of declarative of procedural memory of a subject or task.  Refreshing information in recall helps keep it assessable for ongoing cognition.  According to Souza, Rerko, and Oberauer, (2015) working-memory recall takes place when thinking of one of several concurrently active representations.  The information trace is refreshed in working-memory and the frequency with which an item is refreshed improves recall of this item from visual working-memory.
