At the time of the original publication there was a schism in the field of memory on the issue of a single process or dual-process model of memory, the two processes referring to short-term and long-term memory. [24] [26] Atkinson and Shiffrin cite hippocampal lesion studies as compelling evidence for a separation of the two stores. [1]
The match-to-sample task has been shown to be an effective tool to understand the impact of sleep deprivation on short-term memory. One research study [9] compared performance on a traditional sequential test battery with that on a synthetic work task requiring subjects to work concurrently on several tasks, testing subjects every three hours during 64 hrs of sleep deprivation.
Henry Gustav Molaison (February 26, 1926 – December 2, 2008), known widely as H.M., was an American who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal cortices, piriform cortices, and amygdalae in an attempt to cure his epilepsy.
Memory consolidation was first referred to in the writings of the renowned Roman teacher of rhetoric Quintillian.He noted the "curious fact... that the interval of a single night will greatly increase the strength of the memory," and presented the possibility that "... the power of recollection .. undergoes a process of ripening and maturing during the time which intervenes."
Long-term memory (LTM) is the stage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely. It is defined in contrast to sensory memory , the initial stage, and short-term or working memory , the second stage, which persists for about 18 to 30 seconds.
The processing capacity is of importance to procedural memory because through the process of proceduralization an individual stores procedural memory. This improves skill usage by linking environmental cues with appropriate responses. One model for understanding skill acquisition was proposed by Fitts (1954) and his colleagues. This model ...
With very few works published on memory in the previous two millennia, Ebbinghaus's works spurred memory research in the United States in the 1890s, with 32 papers published in 1894 alone. This research was coupled with the growing development of mechanized mnemometers (an outdated mechanical device used for presenting a series of stimuli to be ...
The rats that were familiar with the task seemed to display normal memory for the task. Thus, there might be a particular stage in the memory process that is vulnerable to selective amnesia. The current hypothesis is that this vulnerable stage is located during the transition from active memory to short term memory. [3]
