Working Memory - 5992 Words

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 span is the number of words that can be recalled if reading a list of say 20 words. Digit span, operation span, reading span etc. are similar tests. Models of working memory evolved over time: Atkinson Shiffrin (1971) Baddeley Hitch (1974)†¦show more content†¦Ã¢â€"   However he tested normally for long-term learning and memory, and had no problems understanding normal speech, so spared LTM. ââ€"   This suggests STM and LTM are distinct and normal STM is not required for LTM to function normally. ââ€"  Garden path sentences show we do retain words in memory as we process them (building up and interpreting sentences) but there are competing theories: ââ€"‹ Just and Carpenter (1992) claimed individual ability to hold multiple interpretations depends on working memory capacityÍ ¾ ââ€"‹ Caplan and Waters (1999) argued working memory isn’t involved as comprehension is done by a separate system. 5.1.3 Working memory as more than STM ââ€"  Baddeley and Hitch (1974) investigated whether STM acts as working memory: ââ€"‹ They used a dualtask paradigm (if two tasks interfere with each other they may be competing for the same limited resource): ââ€"   Participants simultaneously did an STM test, remembering and repeating a sixdigit sequence, along with one of three cognitive tasks: reasoning, language comprehension or list learningÍ ¾ ââ€"‹ They found: ââ€"   load in the STM task adversely affected cognitive performance, although a small number of items could be remembered without affecting the main task much, suggesting that information might be transiently stored and processed simultaneously by working memory, and that there may be two systems involved, one for storage and one for processingÍ ¾Show MoreRelatedWorking 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 memory18399 Words   |  74 PagesPAGES CHAPTER Working Memory 6 Le arn i ng O b j ec t i ves 1.

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 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 connect 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 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 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
