Compare and Contrast Two Models Or Theories of One Cognitive Process with Reference to Research Studies
! The following sample is for the learning objective: Compare and contrast two models or theories of one cognitive process with reference to research studies. What is the question asking for? * A clear outline of two models of one cognitive process. The cognitive process may be memory, perception, decision-making, language or thinking. * Research is used to support the models as described. The research does not need to be outlined in a lot of detail, but underatanding of the role of research in supporting the models should be apparent.. * Both similarities and differences of the two models should be clearly outlined. Sample response The theory of memory is studied scientifically and several models have been developed to help The cognitive process describe and potentially explain how memory works. Two models that attempt to describe how (memory) and two models are memory works are the Multi-Store Model of Memory, developed by Atkinson & Shiffrin (1968), clearly identified. and the Working Memory Model of Memory, developed by Baddeley & Hitch (1974). The Multi-store model model explains that all memory is taken in through our senses; this is called sensory input. This information is enters our sensory memory, where if it is attended to, it will pass to short-term memory. If not attention is paid to it, it is displaced. Short-term memory Research. is limited in duration and capacity. According to Miller, STM can hold only 7 plus or minus 2 pieces of information. Short-term memory memory lasts for six to twelve seconds. When information in the short-term memory is rehearsed, it enters the long-term memory store in a process called “encoding.” When we recall information, it is retrieved from LTM and moved A satisfactory description of back into STM. -
Psychogenic and Organic Amnesia. a Multidimensional Assessment of Clinical, Neuroradiological, Neuropsychological and Psychopathological Features

Psychogenic amnesia is a complex disorder characterised by a wide variety of symptoms. Consequently, in a number of cases it is difficult distinguish it from organic memory impairment. The present study reports a new case of global psychogenic amnesia compared with two patients with amnesia underlain by organic brain damage. Our aim was to identify features useful for distinguishing between psychogenic and organic forms of memory impairment. The findings show the usefulness of a multidimensional evaluation of clinical, neuroradiological, neuropsychological and psychopathological aspects, to provide convergent findings useful for differentiating the two forms of memory disorder.

Review of Short-Term Memory (STM) Short-term memory (STM) is responsible for storing small amounts of material over short periods of Nme A short Nme really means a SHORT Nme-- up to several seconds. Anything remembered for longer than this Nme is classified as long-term memory and involves different systems and processes. !!! Note that this is different that what we mean mean by short- term memory in everyday speech. If someone cannot remember what you told them five minutes ago, this is actually a problem with long-term memory. While much STM research discusses verbal or visuo-spaal informaon, the disNncNon of short vs. long-term applies to other types of sNmuli as well. 3/21/12 Intro to Cognitive Science 3 3. Memory span and magic numbers Amount of informaon varies with individual’s memory span = longest number of items (e.g. digits) that can be immediately repeated back in correct order. Classic research by George Miller (1956) described the apparent limits of short-term memory span in one of the most-cited papers in all of psychology. -
What Is It Like to Be Confabulating?
What is it like to be Confabulating? Sahba Besharati, Aikaterini Fotopoulou and Michael D. Kopelman Kings College London, Institute of Psychiatry, London UK Different kinds of confabulations may arise in neurological and psychiatric disorders. This chapter first offers conceptual distinctions between spontaneous and momentary (“provoked”) confabulations, as well as between these types of confabulation and other kinds of false memories. The chapter then reviews current explanatory theories, emphasizing that both neurocognitive and motivational factors account for the content of confabulations. We place particular emphasis on a general model of confabulation that considers cognitive dysfunctions in memory and executive functioning in parallel with social and emotional factors. It is argued that all these dimensions need to be taken into account for a phenomenologically rich description of confabulation. The role of the motivated content of confabulation and the subjective experience of the patient are particularly relevant in effective management and rehabilitation strategies. Finally, we discuss a case example in order to illustrate how seemingly meaningless false memories are actually meaningful if placed in the context of the patient’s own perspective and autobiographical memory. Key words: Confabulation; False memory; Motivation; Self; Rehabilitation. 1 Memory is often subject to errors of omission and commission such that recollection includes instances of forgetting, or distorting past experience. The study of pathological forms of exaggerated memory distortion has provided useful insights into the mechanisms of normal reconstructive remembering (Johnson, 1991; Kopelman, 1999; Schacter, Norman & Kotstall, 1998). An extreme form of pathological memory distortion is confabulation. Different variants of confabulation are found to arise in neurological and psychiatric disorders. -

Vascular Dementia Vascular Dementia
Vascular Dementia Vascular Dementia Other Dementias This information sheet provides an overview of a type of dementia known as vascular dementia. In this information sheet you will find: • An overview of vascular dementia • Types and symptoms of vascular dementia • Risk factors that can put someone at risk of developing vascular dementia • Information on how vascular dementia is diagnosed and treated • Information on how someone living with vascular dementia can maintain their quality of life • Other useful resources What is dementia? Dementia is an overall term for a set of symptoms that is caused by disorders affecting the brain. Someone with dementia may find it difficult to remember things, find the right words, and solve problems, all of which interfere with daily activities. A person with dementia may also experience changes in mood or behaviour. As the dementia progresses, the person will have difficulties completing even basic tasks such as getting dressed and eating. Alzheimer’s disease and vascular dementia are two common types of dementia. It is very common for vascular dementia and Alzheimer’s disease to occur together. This is called “mixed dementia.” What is vascular dementia?1 Vascular dementia is a type of dementia caused by damage to the brain from lack of blood flow or from bleeding in the brain. For our brain to function properly, it needs a constant supply of blood through a network of blood vessels called the brain vascular system. When the blood vessels are blocked, or when they bleed, oxygen and nutrients are prevented from reaching cells in the brain. As a result, the affected cells can die. -

Memory-Modulation: Self-Improvement Or Self-Depletion?
HYPOTHESIS AND THEORY published: 05 April 2018 doi: 10.3389/fpsyg.2018.00469 Memory-Modulation: Self-Improvement or Self-Depletion? Andrea Lavazza* Neuroethics, Centro Universitario Internazionale, Arezzo, Italy Autobiographical memory is fundamental to the process of self-construction. Therefore, the possibility of modifying autobiographical memories, in particular with memory-modulation and memory-erasing, is a very important topic both from the theoretical and from the practical point of view. The aim of this paper is to illustrate the state of the art of some of the most promising areas of memory-modulation and memory-erasing, considering how they can affect the self and the overall balance of the “self and autobiographical memory” system. Indeed, different conceptualizations of the self and of personal identity in relation to autobiographical memory are what makes memory-modulation and memory-erasing more or less desirable. Because of the current limitations (both practical and ethical) to interventions on memory, I can Edited by: only sketch some hypotheses.

Europe's Journal of Psychology, 2021, Vol. 17(1), 44–52, https://doi.org/10.5964/ejop.2567 Received: 2019-12-17 • Accepted: 2020-04-23 • Published (VoR): 2021-02-26 Handling Editor: Rhian Worth, University of South Wales, Pontypridd, United Kingdom Corresponding Author: Dicle Çapan, Koç University, Rumelifeneri Mahallesi, Sarıyer Rumeli Feneri Yolu, 34450 Sarıyer Istanbul, Turkey. E-mail: [email protected] Abstract Directed Forgetting (DF) studies show that it is possible to exert cognitive control to intentionally forget information. The aim of the present study was to investigate how aware individuals are of the control they have over what they remember and forget when the information is emotional. Participants were presented with positive, negative and neutral photographs, and each photograph was followed by either a Remember or a Forget instruction. Then, for each photograph, participants provided Judgments of Learning (JOLs) by indicating their likelihood of recognizing that item on a subsequent test. In the recognition phase, participants were asked to indicate all old items, irrespective of instruction. Remember items had higher JOLs than Forget items for all item types, indicating that participants believe they can intentionally forget even emotional information—which is not the case based on the actual recognition results. DF effect, which was calculated by subtracting recognition for Forget items from Remember ones was only significant for neutral items. Emotional information disrupted cognitive control, eliminating the DF effect. -
Mild Cognitive Impairment Or Dementia
What To Know When You Have Mild Cognitive Impairment or Dementia People who are told they have mild cognitive impairment (MCI) experience symptoms that are similar to dementia, but aren’t as serious. People with MCI have changes in memory or thinking typically poorer than would be expected for someone their age, but the changes don’t interfere with daily activities. It should be noted that people with MCI have a higher risk of developing dementia, but not all will. Dementia is an umbrella term to describe symptoms that are severe enough to interfere with daily activities. The most common cause of dementia in older adults is Alzheimer’s disease. Other causes include Lewy body dementia, vascular dementia and Frontotemporal diseases. A diagnosis of Alzheimer’s disease or a related disorder doesn’t change who you are and it doesn’t mean you need to stop doing things you find meaningful. It does mean that over time you might have to do them in a different way or have some assistance. The disease does not affect the entire brain all at once. Many areas of the brain are not affected, or are affected much later. Important Messages Dementia can affect memory, We All Should Know thinking, communication and doing everyday tasks. Dementia is not a natural part of aging. It’s possible to live well with dementia. Dementia is caused by diseases of the brain and will There is more to a person affect each person differently. than the dementia.

CHAPTER 6: MEMORY STRATEGIES: MNEMONIC DEVICES in Order to Remember Information, You First Have to Find It Somewhere in Your Memory
CHAPTER 6: MEMORY STRATEGIES: MNEMONIC DEVICES In order to remember information, you first have to find it somewhere in your memory. To be successful in college you need to use active learning strategies that help you store information and retrieve it. Mnemonic devices can help you do that. Mnemonics are techniques for remembering information that is otherwise difficult to recall. The idea behind using mnemonics is to encode complex information in a way that is much easier to remember. Two common types of mnemonic devices are acronyms and acrostics. Acronyms Acronyms are words made up of the first letters of other words. As a mnemonic device, acronyms help you remember the first letters of items in a list, which in turn helps you remember the list itself. Instructor OLC to accompany 100% Online Student Success 1 Examples The following are examples of popular mnemonic acronyms: HOMES Huron, Ontario, Michigan, Erie, Superior Names of the Great Lakes FACE The letters of the treble clef notes in the spaces from bottom to top spells “FACE”. ROY G. BIV Red, Orange, Yellow, Green, Blue, Indigo, Colors of the spectrum Violet MRS GREN Movement, Respiration, Sensitivity, Growth, Common attributes of living Reproduction, Excretion, Nutrition things Create Your Own Acronym Now think of a few words you need to remember. This could be related to your studies, your work, or just a subject of interest. Five steps to creating acronyms are*: 1. List the information you need to learn in meaningful phrases. 2. Circle or underline a keyword in each phrase. 3. Write down the first letter of each keyword.
