Baddeley and Hitch's model of working memory. In 1974 Baddeley and Hitch [11] introduced the multicomponent model of working memory.The theory proposed a model containing three components: the central executive, the phonological loop, and the visuospatial sketchpad with the central executive functioning as a control center of sorts, directing info between the phonological and visuospatial ...
The findings revealed that there may be binge-drinking related functional alteration in recognition working memory processes. This suggests that impaired prefrontal cortex function may occur at an early age in binge drinkers. Another study conducted in 2004 [27] examined the level of response to alcohol and brain response during visual working ...
A person's spatial memory is required to navigate in a familiar city. A rat's spatial memory is needed to learn the location of food at the end of a maze. In both humans and animals, spatial memories are summarized as a cognitive map. [5] Spatial memory has representations within working, short-term memory and long-term memory.
Working memory training is intended to improve a person's working memory.Working memory is a central intellectual faculty, linked to IQ, ageing, and mental health.It has been claimed that working memory training programs are effective means, both for treating specific medical conditions associated with working memory deficit, and for general increase in cognitive capacity among healthy ...
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 ...
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.
Germane load refers to the working memory resources that the learner dedicates to managing the intrinsic cognitive load associated with the essential information for learning. Unlike intrinsic load, which is directly related to the complexity of the material, germane load does not stem from the presented information but from the learner's ...
