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.
Other types of short-term memory show little decline, [9] and semantic knowledge (e.g. vocabulary) actually improves with age. [43] In addition, the enhancement seen in memory for emotional events is also maintained with age. [44] Losing working memory has been cited as being the primary reason for a decline in a variety of cognitive tasks due ...
It is thought to be Baddeley's hypothesized working memory system and the central executive that are the hypothetical systems impaired in DES. [2] The syndrome was once known as frontal lobe syndrome ; however 'dysexecutive syndrome' is preferred because it emphasizes the functional pattern of deficits (the symptoms) over the location of the ...

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.
In 1974, Baddeley and Hitch [5] introduced and made popular the multicomponent model of working memory.This theory proposes a central executive that, among other things, is responsible for directing attention to relevant information, suppressing irrelevant information and inappropriate actions, and for coordinating cognitive processes when more than one task must be done at the same time.
The attack lessens over a period of hours, with older memories returning first, and the repetitive fugue slowly lengthening so that the victim retains short-term memory for longer periods. This characteristic of TGA, where the length of time affected by retrograde amnesia shortens (i.e. older memories return first, followed by more recent ...
Short-term memory impairment is seen early in AD and is a prominent feature, while fluctuating attention is uncommon; impairment in DLB is more often seen first as fluctuating cognition. [143] In contrast to AD—in which the hippocampus is among the first brain structures affected, and episodic memory loss related to encoding of memories is ...
