A. Purpose of the study:

1. What was the purpose of the study?

The purpose of this study was to test the hypothesis that immediate working memory (WM) would be impaired during moderate rising of blood alcohol concentration (BAC), and provision of a rewarding incentive for good performance under alcohol would counteract this impairment (Grattan-Miscio & Vogel-Sprott, 2005). B. Research questions:

1. What were the research questions?

The research questions in this study were:

a) Would the immediate working memory be impaired during moderate raising

of blood alcohol concentrations (Grattan-Miscio & Vogel-Sprott, 2005)?

b) Would provision of a rewarding incentive for good performance under alcohol

counteract this impairment (Grattan-Miscio & Vogel-Sprott, 2005)?

c) What is the result of reaction time and errors between each group after administering the Sternberg Memory Scanning (SMS) method (Grattan-Miscio & Vogel-Sprott, 2005)? C. Participants:

1. Who were the participants in the study?

The participants in this study consisted of 72 healthy undergraduate students. The group consisted of 52 males and 20 females. The participants were randomly divided into 4 groups of 18 with equal amount of males and females.
The groups were divided in the following:
Group A: Group of 18 male and female participants given alcoholic beverages with no reward incentives.
Group P: Group of 18 male and female participants given beverages with no alcohol and no reward incentives. The beverages had a drop of alcohol on the surface and the glasses were sprayed with a mist that contained 50% alcohol and 50% water. This was the placebo group with no incentives.
Group AR: Group of 18 male and female participants given alcoholic beverages and reward…...

Outline and Evaluate the Working Memory Model

...Outline and Evaluate the Working Memory Model The working memory model (WM) explains why we can do two different tasks at the same time, but not two similar tasks. It replaced the idea of a unitary short term memory (STM) in the working memory model information is passed from STM to the central executive and this decides if the information is visual or auditory. Information is then passed to the corresponding store. The central executive is a key component of the WM. It directs information from STM to one of the "slave systems" It also has a very limited capacity and duration so can't attend to too many things at once. The first "slave system" is the phonological loop. This deals with auditory information and maintains the order of the information. It consists of two stores, the phonological store which is like an inner ear and deals with sounds and the articulatory process is used for words which are heard or seen. These words are silently repeated (looped) like an inner voice. The next "slave system" is the visuo-spatial sketchpad. This deals with visual information and spatial information is the relationship between this information. This store is used when you have to plan a spatial task such as getting from one room to another or counting the number of windows your house has. Hitch and Baddley showed support for the WM by conducting an experiment where they gave participants two tasks to do at the same time. They found participants were slower completing these......

Outline and Evaluate the Working Memory Model

...Outline and evaluate the working memory model In the working memory model, there are four main components; The central executive is the most important component as it is involved in problem solving and decision making. It controls attention and plays a vast part in planning and processing information from subsidiary systems and LTM. It is flexible and can process information. It has a limited capacity and can only contain a limited amount of information at one time, Secondly the phonological loop stores a limited amount of speech-based sounds for quick periods. It contains two components. The phonological store (inner ear) allows acoustically coded items to be stored for a brief timing. The articulatory control process (inner voice) allows subvocal repetition of the items stored in the phonological store. Repetition can be prevented by a technique known as ‘articulatory suppression’. The visuo-spatial scratch pad (inner eye) stores visual and spatial information. It is responsible for setting up and manipulating mental images. It has a limited capacity but the limits of the system are independent. The episodic buffer interrogates and manipulates material in the working memory. It has a limited capacity, depending a lot on executive processing. It is capable of binding together information from different sources into chunks/episodes. It interrogates material from LTM to meet the requirements of working memory. The working memory model has many advantages which are that......

...What is memory? Memory is involved in all aspects of our lives, is it  a cognitive thinking process or a way of retaining information or is  it a number of connected stores or even actual information retained. According to Reber (1985), it is possibly all of these. Memory has  not been defined as a single process or fact and several theories exist about its nature, character and structure.  We have vast amounts of information stored in our memory systems which we are able to access quickly and effortlessly, this implies that knowledge stored must be highly organised to allow us to retrieve the appropriate information for a given situation. This organising will be  determined by the way that information is encoded into memory. The way the knowledge is organised will determine the type of process required to access that information in the future.  Atkinson and Shiffrin (1969) suggested that memory comprised of three separate stores. The sensory memory store, the short-term memory and the long term-memory each store has a specific and relatively inflexible function. This was called the multi-store model.  There are two main memory stores short term memory (stm) and long term memory (ltm),they are studies in terms of there ability to encode, which means make sense of information, also by there capacity, how much information is stored and by duration ,how long the information  can be stored.  How does the short-term memory store work? Conrad (1964) suggested that......

A Study on the Effect of Chewing Gum on Students’ Working Memory

...I. Proposed Project Title A Study on the Effect of Chewing Gum on Students’ Working Memory II. Objectives of the Study The study aims to characterize the relationship between chewing of gum and the working memory of students from the College of Engineering. Specifically, the study aims to discern whether chewing gum positively affects working memory capacity whether through visual digits, shapes, or simple math. By determining the results, the study also aims to inform students of a useful tool in focusing on course material. III. Review of Relevant Literature Working memory capacity is a type of memory used daily, and is especially important in education as it measures the potential to learn. Stephens and Tunney (2004a) found that chewing gum improved working memory capacity, specifically digit span and spatial span. Hirano et al. (2008) came to the same conclusion through a different measure of working memory (the n-back task). According to Allen and Smith (2009), further research is needed in order to support this claim. IV. Process Diagram The response variable, working memory capacity, will be measured through a test that measures the ability to recall, in correct order, an increasing sequence of units, such as digits or shapes. Tests of this nature are available for free online, some of which, such as......

...Title : Alcohol abuse Alcohol abuse is alcoholism which is often consuming large amount of alcohol beverages despite negative consequences by the alcoholics. Alcohol abuse is mainly due to the ready availability of alcohol and the price of alcohol drinking is cheap which many people can afford to purchase it. Alcohol abuse can cause alcohol abuse, brain damage and damage the heart and lead to high blood pressure, congestive heart failure and stroke. Social ill are the causes of alcohol abuse. Adolescent will feel despair and helpless when they have diagnose illness which do not have cure. This let adolescent to consume enormous amount of alcohols to escape from facing the real life. Besides that, adolescent will take large amount of alcohol to forget about the indirect of family violence that happened due to broken family. Drinking alcohol will let teenager to temporary forget the problem they faced in life. Alcohol abuse will lead to brain damage. If adolescent consuming huge amount of alcohol for period of time can, it can impair brain development. Adolescent will exhibits cognitive effect in brain such as learning impairment and memory dysfunction. Moreover, they will be in an unconscious state after drinking the alcohols drink. In addition, large amounts consume of alcohols can damage the heart and lead to high blood pressure, congestive heart failure and stroke. Consume large amount of alcohol will puts more fats into the circulation of alcoholic body. This......

Integration of Working Memory Training

...Integration of Working Memory Training Working memory has been a growing topic of interest in the field of Speech Language Pathology. It affects all aspects of children’s development, including speech, language, reading, and classroom success. Working memory deficits are prevalent in people with schizophrenia, attention deficit hyperactivity disorder (ADHD), traumatic brain injuries, learning disabilities, specific language impairment (SLI), and intellectual disabilities (Van der Molen, Van Luit, Van der Molen, Klugkist, & Jongmans, 2010). With the rising awareness of how working memory deficits can effect children’s development, the question of whether speech language pathologists should assess and treat these deficits has been asked more and more. Assessing and treating working memory deficits are key and can help many different populations improve in their speech and language development. Assessment for working memory deficits and working memory training should be standard and included into the normal regime. The following paper will touch on what working memory is. As well as how a deficit in working memory can effect children’s development, whether they are typically developing children, or children with other disorders. Some assessment options and then training techniques of working memory will be introduced as well. What is Working Memory? Working memory requires the ability to attend to new information, retain incoming information, and manipulate......

The Working Memory Model

...The working memory model has three separate components. The central executive system allocates attention to different inputs and monitoring the operation of the other two components. The phonological loop has two sub-components, the articulatory control system, where information is rehearsed subvocally, and the phonological store, where speech input is held for a very brief duration. The third component, the visuo-spatial sketchpad deals with visual and spatial information coming either direct from the senses, or retrieved from long-term memory. However, much of the key evidence for this model comes from the study of brain-damaged individuals, where it is impossible to make `before and after` comparisons, thus limiting the validity of any conclusions drawn. Working memory has also been useful in understanding some of the cognitive changes associated with mental illnesses. For example, Park et al. (1999) found that working memory deficit may be an important indicator in schizophrenia. There are many strengths and weaknesses of the working memory model. One strength of the model is that KF who was a brain damaged patient who had an impaired STM. Their model doesnât really explain exactly what the central executive is, apart from being involved in attention. On the other hand, another strength of the model is that Short words are recalled well than long words (the word length effect). This is evidence for the limited capacity of the phonological loop, since more short......

Outline and Evaluate the Working Memory Model.

...Outline and evaluate the Working Memory Model. The Working Memory Model (WMM) is a model of the STM. The WMM was proposed by Baddeley and Hitch when they carried out a Dual-task method experiment only to find that the MSM was too simple as it stated that the STM is only one store. The model shows that information is first received by the Central Executive. The Central Executive has overall control of the STM and it is multi-modal meaning it can process information from different senses. This information can then go to one of two stores. If it is speech-based information it will be transferred to the Phonological Loop. It has two subcomponents, phonological store and articulatory control process. The phonological store is the inner ear and contains snippets of sounds either from the outside world or recalled from long term memory. The articulatory control process is the inner voice which essentially is our own voice inside our heads as it constantly repeats or rehearses information so therefore preventing forgetting by decay. The visuo-spatial sketch pad is visual short term memory, or the inner eye. It can manipulate images in two and three dimensions. The WMM shows memory as an active process as the Central Executive can store and retrieve information from either slave store. As this is a model of the STM, all three stores have a limited duration and capacity. A good thing about the WMM is that it’s pioneering. This model is the first of its kind to explain STM as having......

Outline and Evalute the Working Memory Model (12)

...Outline and evaluate the working memory model. The working memory model was proposed in 1974 by Baddeley and Hitch, who felt that Atkinson and Schifrin’s multi store model, was too simplistic, therefore the working memory model acted as an alternative, unlike the multi store model the working memory model presents short term memory stores because it focuses on the short term memory. The term working memory is used by Baddeley and Hitch to refer to the part of the memory that is active, for example calculating sums or reading a sentence all of which are collecting data to be stored. There are three parts main of the original working memory model: the central executive, phonological loop, visual spatial sketch pad and the later added episodic buffer. The central executive controls attention and draws on the other the other two systems also known as slave systems. The central executive only has a limited capacity, which is supported by the dual task technique. This is when an individual struggles to do tasks that require the same component – this is because they are competing for the central executive’s capacity. There is evidence to suggest that there may be more than one component of the central executive, for example Eslinger and Damasio study. Their findings were that a patient, who had recently had a brain tumour removed, performed well on tasks that required reasoning, but not on decision making tasks. The two slave systems in the working memory model have......

...TEMPERAMENT AND TEMPERAMENTAL TRAITS Temperament refers to an individual’s natural behavioral style which is present from birth. It is the how of behavior, not the wh y, wha t, or how well . It is not to be confused with motivation (why) or ability (what and how well). Temperamental traits are innate, not produced by the environment. However, the environment - including the behavior of the parent - does interplay with temperament and influences the expression of temperamental traits. Nine characteristics or temperamental traits were originally identified in the New York Longitudinal Study. The NYLS was begun in 1956 by Doctors Alexander Thomas, Stella Chess, and Herbert Birch, and is still ongoing. This project, the first of several longitudinal studies of temperament, has followed over 130 persons from infancy to adulthood, identifying the temperamental characteristics of each child, studying the influences of these traits on the child’s development and interactions with their environments. The nine temperamental traits can be defined as follows: 1. Activity level. How active is the child typically and how much of the time is the child active? 2. Rhythmicity (regularity). How predictable is the child with regard to the timing of his/her sleep, appetite, and elimination patterns? 3. Approach/withdrawal. Is the child’s initial response to newness - new person, foods, places, objects - positive or negative? 4. Adaptability. How does the child deal with transition, change,...

Outline and Evaluate Working Memory Model

...Atkinson and Shiffrin's (1968) Multi-Store model of memory was extremely successful in terms of the amount of research it generated. However, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory. Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called working memory. Baddeley and Hitch (1974) argue that the multi-store model is too simplistic. Instead of all information going into one single store, there are different systems for different types of information. Working memory consists of a central executive which controls and co-ordinates the operation of two subsystems: the phonological loop and the visuo-spatial sketchpad. Baddley and Hitch investigated if participants can use different parts of working memory at the same time. They conducted an experiment in which participants were asked two perform two tasks at the same time - a digit span task which required them to repeat a list of numbers, and a verbal reasoning task which required them to answer true or false questions. The result was that as the number of digits increased in the digit span task, participants took longer to answer the reasoning questions, but not much longer. They didn't make any more errors in the verbal reasoning task as the number of digits increased. This was also known as the dual method. They concluded that the verbal reasoning task made us of the central executive and the digit......

Outline and Evaluate the Working Memory Model (12 Marks)

...Outline and evaluate the working memory model (12 marks) Baddeley and Hitch proposed that memory has 4 components. The central executive, phonological loop, visuospatial sketchpad and the episodic buffer. The central executive decides how to share out and direct attention to incoming information. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. It is sub-divided into two other components, the phonological store (inner ear), which holds acoustically coded information, and the articulatory process (inner voice), which allows for sub vocal rehearsal (words you are about to say). Furthermore, the visuospatial sketchpad (inner eye) is responsible for storing visual and spatial information. In other words, it codes information in images and can create and manipulate visual and spatial images. Finally, the episodic buffer. This component takes information from different sources and integrates them together. For example, Baddeley suggested if we imagine an elephant playing ice hockey, we have to draw out images stored in long term memory and combine them into a moving image. The working memory model is good and is an improvement over the multi-store model. It demonstrates how the short term memory works because it explains how we can store information briefly and simultaneously manipulate it, for example, mental arithmetic. This shows that the model has face validity, which means that the test appears to measure what it......

Outline and Evaluate the Working Memory Model Essay

...The working memory model (Baddeley and Hitch 1974) replaced the idea of a unitary STM, it suggests a system involving active processing and short term storage of information. The working memory model consists of four components which each have a different job. The Central executive (CE) is the key component and can be described as attention. It has a limited capacity and controls two ‘slave’ systems that also have limited capacity. The function of the CE is to direct attention to particular tasks, determining how the brain's ‘resources’ are used for the task. The ‘resources’ are the three ‘slave’ systems. Data arrives from the senses or from the long term memory. Because the CE has a very limited capacity it can’t attend to too many things at once and has no capacity for storing data. The next component is the Phonological loop (PL) which is one of the ‘slave’ systems. This deals with auditory information and preserves the order of information. Baddeley (1986) further subdivided this loop into: - The phonological store which holds the words you hear, like and inner ear. - An articulatory process which is used for words that are heard or seen. These words are silently repeated like an inner voice. This is a form of maintenance rehearsal. The next component is the episodic buffer which is another ‘slave’ system. Baddeley (2000) added the episodic buffer because he realised the model needed a general store. The Phonological loop and Visuo-Spatial......

Working Memory Model by Baddely

...Discuss the working memory model The working memory model was proposed by Baddeley & Hitch as an alternative to the multi-store model of memory. It has been developed to directly challenge the concept of a single unitary store for short-term memory. It is divided into four components, being the central executive, phonological loop ( which includes the two sub components , auditory and articiulatory store) episodic buffer and the visuo spatial sketch pad. The most important component is the central executive; it is involved in problem solving/decision-making. It also controls attention and plays a major role in planning and synthesizing information. It is flexible and can process information from any modality which makes it modality free, although it does have a limited storage capacity and so can attend to a limited number if things at one time. Lastly the CE is responsible for monitoring the slave systems ( the other components) and directing which slave system to send information to.   Another component of the working memory model is the phonological loop, it stores a limited number of speech-based sounds for brief periods. It is thought to consist of two components - the auditory store (inner ear)which is modality specific as it receives it’s inputs from the ear and long term memory, it allows acoustically coded items to be stored for a brief period. The articulatory store (the inner voice) allows repetition of the material stored in the phonological store. This......

...Alcohol is a compound of carbon, hydrogen and oxygen, which can be combined together in many different ways. There are many different kinds of alcohol, the commonest being called ethyl alcohol. Ethyl alcohol, or ethanol, is present in varying amounts in beers and wines, and in distilled liquors such as whiskey, gin, and rum. Alcohol consumption touches many million people around the world. The use of alcohol depends on an individual’s social, cultural, or religious background.  One of the earliest mentions of wine making is from an Egyptian papyrus dated 3,500 BC. However, alcohol drinking is thought to go back almost as far as the human race does. Alcohol has been central to social, religious and personal use all over the world throughout history.  When an individual consumes alcohol there are both short term and long term effects.  The most immediate effect of alcohol consumption is change of mood. Even though alcohol is makes you feel excitement, happiness and relaxation it is in fact a depressant. Alcohol in the bloodstream causes impairment of motor co-ordination and slows down central nervous system activity, which gives the impression of clumsiness and can lead to alcohol related accidents. The more intoxicated a person has slurred speech, blurred vision and the loss of balance. Furthermore it switches off the part of the brain that controls judgment which can result in greater risk taking. However drinking in very large quantities can damage vital bodily......
