Instead of short-term memory, they used the phrase ‘working memory’ to reflect their view that this is the area of memory that is active when you are working on information. Working memory consists of the following parts: The different components of the Working Memory have certain functions to help information pass through the short-term store into the long term store. The first part of the Working Memory model is the central executive; it is the controller of this model. This component is the main part of the Working Memory as it allocates resources to other components. It is not visual or auditory.
Working Memory Model * Outline and evaluate The Working Memory Model. Working memory model developed by Baddeley and Hitch, only focusses on short term memory and sees memory as an active store where information could be held and manipulated. The working memory model is a challenge to the earlier work of Shiffrin and Attkins’ multi-store model which sees short term memory as passive and unitary. There are three components to the working memory model. The first is central executive: the central executive is like the boss which coordinates the memory system and allocates resources to the other two slave system.
This theory now could predict and explain a phenomenon. Both followed the factor analysis techniques to observe the stability and structure of personality focusing mainly on two dimensions, they were Extraversion and Neuroticism during which they found the third factor (openness to experiences) Later on, McCrae and Costa concluded the five factor personality inventory (NEO-PI) that consisted of an unpublished three-factor inventory by Eysenk. Agreeableness and Conscientiousness were not developed until the release of the NEO-PI (Feist & Feist, 2009). Central assumptions about human nature Eysenk found
different stores for each sense) Short Term Memory • Duration: 0-18 seconds • Capacity: 7 +/- 2 items • Encoding: mainly auditory Long Term Memory • Duration: Unlimited • Capacity: Unlimited • Encoding: Mainly Semantic (but can be visual and auditory) Evaluation of the Multi-Store Model Strengths Many memory studies provide evidence to support the distinction between STM and LTM (in terms of encoding, duration and capacity). The model can account for primacy & regency effects. The model is influential as it has generated a lot of research into memory. The model is supported by studies of amnesiacs: For example the HM case study. HM is still alive but has marked problems in long-term memory after
Discuss Theories of Memory and Relate to Your Own Memory Atkinson & Shiffrin (1968) and Badderly & Hitch (1974) produced two well known theories of memory. This discussion will explain the two theories supplying sufficient evidence to support each theory. It will outline any criticisms of each theory and demonstrate ways that I use memory. The disscusion will come to a closure with a final conclusion based on the discussion held. The definition of memory is the ability to store things in a persons mind and to be able to recall them.
Baddeley and Hitch developed a multi-store model of the short term memory called the working memory model. The model consists of three components which make up the short term memory. The central executive is a key feature of the whole store as it allocates the information to the two “slave systems” which are the visuospatial spatial sketchpad and the articulatory - phonological loop. The VSS stores visual and spatial information. Mental and visual images are an example.
The components of the WMM are split into 3 main sections; Central executive, visuo-spatial scratch pad and phonological store. The Central executive is the system in overall charge which allocates information to the other subsystems. It is very flexible and can process information in any sensory modality. Also the central Executive can hold and manipulate information, and like other stores in WMM, it has a limited capacity. Visuo-spatial scratch pad is the inner eye, it is where you see it in your brain.
It is expected that these skills will be developed through use of the core practicals and are closely linked to the requirements of ‘How Science Works’ criteria. Examiners and moderators therefore placed particular emphasis on seeking evidence of these skills in candidates’ reports. It was disappointing to see that evidence for a number of these skills was frequently absent from reports. The most common omissions were; • • Assessment of practical skills (b)(ii) – ‘Identifies and explains possible systematic or random errors in results.’ Analyse and interpret data to provide evidence, recognising correlations and causal relationships (using descriptive statistics such as standard deviation and discussing the problems of correlation and causation as illustrated in Unit
I will then describe a model which gives us a way of conceptionalising working memory, followed by a description of some difficulties of working memory. I will describe studies that link difficulties with working memory to difficulties for dyslexic individuals, and discuss them. 2 DYSLEXIA McLoughlin et al. (2002) proposed a definition based on working memory theory – “Developmental dyslexia is a genetically inherited and neurologically determined inefficiency in working memory, the information processing system fundamental to learning and performance in conventional educational and work settings. It has a particular impact on verbal and written communication as well as on organisation, planning and adaptation to change.” (p.19).
What are The Branches of Chemistry? Abstract Chemistry is one of the important sciences in the world because it explains many things in our physical world. It is considered as the center of science because it contains essential information which could be necessary for other people who study other sciences such as physics, biology, ecology and geology. This essay will discuss some of the branches of chemistry and the importance of each one of them. The research strategy used was to consult up to date academic databases, newspapers and books.
