The term "working memory" was coined by Miller, Galanter, and Pribram, [5] [6] and was used in the 1960s in the context of theories that likened the mind to a computer.In 1968, Atkinson and Shiffrin [7] used the term to describe their "short-term store".
Baddeley's model of the phonological loop. The phonological loop (or articulatory loop) as a whole deals with sound or phonological information.It consists of two parts: a short-term phonological store with auditory memory traces that are subject to rapid decay and an articulatory rehearsal component (sometimes called the articulatory loop) that can revive the memory traces.
The working memory model. In 1974 Baddeley and Hitch proposed a "working memory model" that replaced the general concept of short-term memory with active maintenance of information in short-term storage. In this model, working memory consists of three basic stores: the central executive, the phonological loop, and the visuo-spatial sketchpad.
Later research on short-term memory and working memory revealed that memory span is not a constant even when measured in a number of chunks. The number of chunks a human can recall immediately after presentation depends on the category of chunks used (e.g., span is around seven for digits, around six for letters, and around five for words), and even on features of the chunks within a category.
Working memory is impaired in the early stages of Alzheimer's disease which affects the ability to do everyday tasks. It also affects executive control of working memory. It was found that participants who had mild Alzheimer's disease were able to use working memory strategies to enhance verbal and spatial working memory performance. [43] It ...
Scientists around the world are working to prevent and treat it. Tracy’s lab at the Buck Institute is studying memory loss from Alzheimer’s disease and frontotemporal dementia.
As with iconic memory, echoic memory only holds superficial aspects of sound (e.g. pitch, tempo, or rhythm) and it has a nearly limitless capacity. [16] Echoic memory is generally cited as having a duration of between 1.5 and 5 seconds depending on context [16] [17] [18] but has been shown to last up to 20 seconds in the absence of competing ...
