The Working Memory Model Research Paper - 1252 Words.
The major weakness of the working memory model is the central executive which, ironically, is its most important component. There is relatively little research evidence for its existence and it is by its nature very hard to directly investigate, although some recent research into patients with Alzheimer’s disease (e.g. Baddeley et al, 1991) has identified how an impaired central executive.
Lesson Plan: Working Memory for Kids Grades: Year 3-6 Age: 7-11 years Overview Working memory is the ability to hold information in mind and manipulate it. It is an essential cognitive skill for school learning. This lesson introduces the concept of working memory to children, shows that there is a limit.
To widen explanations of memory, Baddeley and Hitch (1974) proposed their working memory model (WMM) offering an interacting link between sensory storages and long-term memory. Working memory (WM) can be defined as control-system with limited processing and storing-capacity, and WMM consists of phonological-loop (PL), visuo-spatial sketchpad (VSS), central-executive (CE), and episodic-buffer.
This model of memory states that our memory is made up of three separate stores; sensory memory, short-term memory (STM) and long-term memory (LTM). Each store has a different capacity and duration. Information from the environment first enters our STM. If we pay attention to this information, it will be passed onto the Sensory Memory.
The primacy and recency effect supports the multi store model for memory because it argues the fact that short term and long term memory are two separate stores in memory. In Murdock’s study, participants had to learn a list of words that varied in length from 10 to 30 words and free recall them, with each word being viewed for 2 seconds.
The working memory model replaced the idea of a unitary Short-term memory store (STM) and suggested a system involving multiple stores consisting of active processing and short-term storage of information.In this model, STM is an active processor (working memory) which the “Central Executive” (CE) “attends to and works on” either speech-based information received from the articulatory.
Professor Willingham has written that working memory has “limited space”, meaning that if people try to juggle too many facts they tend to lose track. In the interview with ResearchED founder and TES columnist Tom Bennett, Professor Willingham said knowledge of the limitations of working memory “might help a teacher understand why a student is struggling with something”.
