These results show that different factors affect short-term recall (disruption of rehearsal) and long-term recall (semantic similarity). Other manipulations (e.g., semantic similarity of the words) affect only memory for earlier list words, but do not affect memory for the most recent few words. Recall for words from earlier in the list (it is presumed, stored in long-term memory) are unaffected. Other evidence comes from experimental studies showing that some manipulations impair memory for the 3 to 5 most recently learned words of a list (it is presumed that they are held in short-term memory). This is interpreted as showing that the short-term store is spared from damage and diseases. Patients with this form of amnesia have an intact ability to retain small amounts of information over short time scales (up to 30 seconds) but have little ability to form longer-term memories (illustrated by patient HM). One form of evidence cited in favor of the existence of a short-term store comes from anterograde amnesia, the inability to learn new facts and episodes. The exact mechanisms by which this transfer takes place, whether all or only some memories are retained permanently, and even to have the existence of a genuine distinction between stores, remain controversial.Įvidence Anterograde amnesia The final storage is long-term memory, which has a very large capacity and is capable of holding information possibly for a lifetime. Short-term memory does not have a large capacity like sensory memory, but holds information for seconds or minutes. A representation of that rapidly decaying memory is moved to short-term memory. The model states that memory is first stored in sensory memory, which has a large capacity but can only maintain information for milliseconds. This model is referred to as the "modal model", most famously detailed by Shiffrin. A model of memory developed in the 1960s assumed that all memories are formed in one store and transfer to others store after a small period of time. The idea of separate memories for short-term and long-term storage originated in the 19th century.
