Editing Atkinson–Shiffrin memory model (section)

==Long-term store==
{{Main|Long-term memory}}
The ''long-term store'' (also ''long-term memory'') is a more or less permanent store.  Information that is stored here can be "copied" and transferred to the short-term store where it can be attended to and manipulated.

===Transfer from STS===
Information is postulated to enter the long-term store from the short-term store more or less automatically. According to Atkinson and Shiffrin model, transfer from the short-term store to the long-term store is occurring for as long as the information is being attended to in the short-term store. In this way, varying amounts of attention result in varying amounts of time in short-term memory. Ostensibly, the longer an item is held in short-term memory, the stronger its memory trace will be in long-term memory. Atkinson and Shiffrin cite evidence for this transfer mechanism in studies by Hebb (1961)<ref name=Hebb1961 /> and Melton (1963)<ref name=Melton1963 /> which show that repeated rote repetition enhances long-term memory. One may also think to the original Ebbinghaus memory experiments showing that forgetting increases for items which are studied fewer times.<ref name=Ebbinghaus /> Finally, the authors note that there are stronger encoding processes than simple rote rehearsal, namely relating the new information to information which has already made its way into the long-term store.<ref name=AtkinsonShiffrin1968 />

===Capacity and duration===
In this model, as with most models of memory, long-term memory is assumed to be nearly limitless in its duration and capacity. It is most often the case that brain structures begin to deteriorate and fail before any limit of learning is reached. This is not to assume that any item which is stored in long-term memory is accessible at any point in the lifetime.  Rather, it is noted that the connections, cues, or associations to the memory deteriorate; the memory remains intact but unreachable.<ref name=AtkinsonShiffrin1968 />
