Think of working memory as involving a mental blackboard—that is, as a workspace that provides a temporary holding store so that relevant information is highly accessible and available for inspection and computation. When cognitive tasks are accomplished, the information can be easily erased, and the process can begin again with other information. 1.1. A Computer Metaphor The computer, so useful a metaphor in cognitive psychology, offers an intuitively appealing model for thinking about the nature and structure of working memory. SMITMC06_0131825089.QXD 3/28/06 6:57 AM Page 241 REVISED PAGES 1. Using Working Memory Simplifying the workings of a computer, there are two means by which information is stored, the hard disk and random-access memory (RAM). The hard disk is the means by which information is stored permanently in a stable and reliable form; all software programs, data files, and the operating system of the computer are stored on the hard disk. To use this stored information you must retrieve it from the hard disk and load it into RAM. Now for the analogy: the information stored in the hard disk is like long-term memory, RAM corresponds to working memory. The notion of working memory as a temporary workspaceShow MoreRelatedWorking Memory5992 Words   |  24 Pagesï » ¿Working Memory ââ€"  Working memory enables us to keep things in mind for short periods (215 seconds) as we think, e.g. while reading, making a list etc. ââ€"  It s related to but different to short-term-memory (STM) and long-term-memory (LTM). ââ€"  Chapter focuses on Baddley s (1986) model of phonological working memory, vocabulary acquisition and computational modelling of working-memory. ââ€"  The concept of span means how many items from a briefly presented set can be remembered, e.g. word spanRead MoreWorking Memory and Its Benefits Essay2434 Words   |  10 Pagesfunctioning effectively to face immediate environmental changes in our everyday life. This ability is called the Working Memory. The term working memory was coined by Miller, Galanter, and Pribram in 1960 (Baddeley, 2003). It refers to the temporary storage in the brain for manipulation of necessary information to execute cognitive tasks. According to Baddeley and Hitch’s study (1974), working memory comprises three main components, a control system, the central executive and two storage systems, the visuospatialRead MoreWorking Memory Trainings and Limits of Its Transfer2205 Words   |  9 PagesWorking Memory Trainings and Limits of Its Transfer Working memory is the ability one has to manipulate and maintain information mentally, while ignoring other irrelevant distractions and interference in the brain. In recent years, there has been an increasing amount of interest in this field. Research in this area is in fact, still a currently active and quickly developing area. Working memory is so essential in every person’s everyday life that one would not be able to function and perform theirRead MoreWorking Memory : The State Of Memory1367 Words   |  6 PagesWorking Memory describes the state of memory we are actively engaged with. It performs the functions of receiving, temporarily holding and manipulating information (Baddeley, 2010). To assess memory psychologists have found it helpful to define their theories as models. Atkinson and Shiffrin ‘s 1968 Stage Model of Memory defined 3 main components of memory systems; sensory memory from perception of experience that becomes short-term memory (STM), which through rehearsal loads more permanent connectionsRead MoreThe Effects Of Bilingualism On The Executive Function And Working Memory1948 Words   |  8 Pagesmore rapidly to conditions that placed greater demands on working memory. In all cases the bilingual advantage was greater for older participants. These two findings imply that bilingualism have beneficial effects on the executive function and working memory. Besides the excellent executive function ability and the great capability of working memory, researchers also found out that bilinguals have advantages on a particular working memory. The study of Luo et.al (2013) demonstrated that bilingualsRead MoreThe Aging Memory: A Research on Working Memory and Recall Essay1969 Words   |  8 PagesThe aging memory: short-term memory and rec all performance differences found in age groups. 1. Introduction The following research proposal aims to continue to further the discussion and study into human memory. However, specifically more into the difference that can be found between age groups in terms of short-term memory and recall performance. Motivation to undertake in such a study can be said to expand on the existing knowledge as well as to close any gaps due to lack of insight and testingRead MoreEvaluate the Working Memory Model1310 Words   |  6 PagesEvaluate the Working Memory Introduction Human memory is a complex cognitive structure, which can be defined in many ways. One would argue that memory is 1.) The mental function of retaining information about stimuli, event, images, ideas, etc. after the original stimuli is no longer present. 2.) The hypothesized storage system in the mind that holds this information is so retained. A clear distinction is made between different types of memory systems and can be divided into subclasses. TheRead MoreThe Effect Of Speed Pressure On Working Memory During Mental Arithmetic Tasks1211 Words   |  5 Pagesspeed pressure on working memory during mental arithmetic tasks. 392 undergraduate students’ working memory capacities were measured and participants were divided into high and low working memory groups. They were then randomly assigned into the fast or slow condition and tested with the critical stimuli compromised of addition equations. The findings showed that fast conditions result in higher error rates than the slow conditions. The speed pressure also caused high working memory individuals to shiftRead MoreThe Effects Of Anxiety Disorders And Situational Anxiety On Short Term Working Memory1651 Words   |  7 PagesAbstract: This research paper summarizes the results of three academic articles exploring the effects of anxiety disorders, and situational anxiety on short term working memory. These three articles all used different methods in attempt to connec t anxiety with working memory performance. To summarize, these studies attempt to answer the question of whether or not an attentional bias toward threatening (anxiety triggering) exposure or conditions, causes a greater susceptibility to distraction andRead MoreWorking Memory Model Essay941 Words   |  4 Pagesfor being a very simplistic view of memory. They saw short term memory as a store that had many individual sections inside it. This was supported by patient KF who had epilepsy, the doctor wanted to try and remedy this by removing his hippocampus. This surgery was done, however instead of fixing his epilepsy, it damaged his short term memory, yet he still had his long term memory intact. In the multi-store model it states that in order to have long term memory, one needs to have gone through the
