Baddeley's Model Of Working Memory
Baddeley's model of working memory is a model of human memory proposed by Alan Baddeley and Graham Hitch in 1974, in an attempt to present a more accurate model of primary memory (often referred to as short-term memory). Working memory splits primary memory into multiple components, rather than considering it to be a single, unified construct. Baddeley and Hitch proposed their three-part working memory model as an alternative to the short-term store in Atkinson and Shiffrin's 'multi-store' memory model (1968). This model is later expanded upon by Baddeley and other co-workers to add a fourth component, and has become the dominant view in the field of working memory. However, alternative models are developing, providing a different perspective on the working memory system. The original model of Baddeley & Hitch was composed of three main components: the ''central executive'' which acts as a supervisory system and controls the flow of information from and to its ''slave systems' ...

Alan Baddeley
Alan David Baddeley CBE Fellow of the Royal Society, FRS (born 23 March 1934) is a British psychologist. He is known for his research on memory and for developing the three-component model of working memory. He is a professor of psychology at the University of York. Biography Baddeley was born in Leeds, Yorkshire on 23 March 1934. He lived there with his parents, Donald and Nellie Baddeley, until leaving for university. He decided to study psychology and was originally interested in psychoanalysis. Later he changed his focus to evidence-based psychology. In 1956, Baddeley went to the United States of America to continue his studies. After spending a year in America, he returned home. He then went to Cambridge, where he met and married Hilary Ann White. Baddeley and his wife have three sons. Baddeley has taught and conducted research at University of Sussex, University of Stirling, MRC Applied Psychology Unit, Churchill College, Cambridge, Churchill College, University of Cambr ...

Articulatory Suppression
Articulatory suppression is the process of inhibiting memory performance by speaking while being presented with an item to remember. Most research demonstrates articulatory suppression by requiring an individual to repeatedly say an irrelevant speech sound out loud while being presented with a list of words to recall shortly after. The individual experiences four stages when repeating the irrelevant sound: the intention to speak, programming the speech, articulating the sound or word, and receiving auditory feedback. Phonological loop and visuospatial sketchpad When studying articulatory suppression, many researchers examine the phonological loop and the visuospatial sketchpad as well. The phonological loop is the process of hearing information, which has direct access to one's phonological store (i.e. one's short-term memory). The visuospatial sketchpad is information that is seen (visual information), which only has access to the phonological store through one's articulatory co ...

The Magical Number Seven, Plus Or Minus Two
"The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information" is one of the most highly cited papers in psychology. It was written by the cognitive psychologist George A. Miller of Harvard University's Department of Psychology and published in 1956 in ''Psychological Review''. It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2. This has occasionally been referred to as '' Miller's law''. Miller's article In his article, Miller discussed a coincidence between the limits of one-dimensional absolute judgment and the limits of short-term memory. In a one-dimensional absolute-judgment task, a person is presented with a number of stimuli that vary on one dimension (e.g., 10 different tones varying only in pitch) and responds to each stimulus with a corresponding response (learned before). Performance is nearly perfect up to five or six different stimuli but declines as the num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ROBO1
Roundabout homolog 1 is a protein that in humans is encoded by the ''ROBO1'' gene. Function Bilateral symmetric nervous systems have special midline structures that establish a partition between the two mirror image halves. Some axons project toward and across the midline in response to long-range chemoattractants emanating from the midline. The protein encoded by ROBO1 is structurally similar to a Drosophila integral membrane protein which is encoded by the Drosophila roundabout gene (a member of the immunoglobulin gene superfamily) and is both an axon guidance receptor and a cell adhesion receptor, known to be involved in the decision by axons to cross the central nervous system midline. Two transcript variants encoding different isoforms have been found for ROBO1. Clinical significance ''ROBO1'' was implicated in a communication disorder based on a Finnish pedigree with severe dyslexia. Analyses revealed a translocation had occurred disrupting ''ROBO1''.

Amnesia
Amnesia is a deficit in memory caused by brain damage or brain diseases,Gazzaniga, M., Ivry, R., & Mangun, G. (2009) Cognitive Neuroscience: The biology of the mind. New York: W.W. Norton & Company. but it can also be temporarily caused by the use of various sedative and hypnotic drugs. The memory can be either wholly or partially lost due to the extent of damage that is caused. There are two main types of amnesia: * Retrograde amnesia is the inability to remember information that was acquired before a particular date, usually the date of an accident or operation. In some cases, the memory loss can extend back decades, while in other cases, people may lose only a few months of memory. * Anterograde amnesia is the inability to transfer new information from the short-term store into the long-term store. People with anterograde amnesia cannot remember things for long periods of time. These two types are not mutually exclusive; both can also occur simultaneously. Case stud ...

Annual Review Of Psychology
The ''Annual Review of Psychology'' is a peer-reviewed academic journal that publishes review articles about psychology. First published in 1950, its longest-serving editors have been Mark Rosenzweig (1969–1994) and Susan Fiske (2000–present). As of 2023, ''Annual Review of Psychology'' is being published as open access, under the Subscribe to Open model. As of 2024, '' Journal Citation Reports'' gives the journal a 2023 impact factor of 23.6, ranking it first of 92 journal titles in the category "Psychology (Science)" and first of 218 titles in the category "Psychology, Multidisciplinary (Social Science)". History In 1947, the board of directors of the publishing company Annual Reviews asked a number of psychologists if it would be useful to have a journal that published an annual volume of review articles that summarized recent developments in the field. Responses were very positive, so in September 1947 they announced that the first volume of the ''Annual Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ventral Stream
The two-streams hypothesis is a model of the neural processing of vision as well as hearing. The hypothesis, given its initial characterisation in a paper by David Milner and Melvyn A. Goodale in 1992, argues that humans possess two distinct visual systems. Recently there seems to be evidence of two distinct auditory systems as well. As visual information exits the occipital lobe, and as sound leaves the phonological network, it follows two main pathways, or "streams". The ventral stream (also known as the "what pathway") leads to the temporal lobe, which is involved with object and visual identification and recognition. The dorsal stream (or, "where pathway") leads to the parietal lobe, which is involved with processing the object's spatial location relative to the viewer and with speech repetition. History Several researchers had proposed similar ideas previously. The authors themselves credit the inspiration of work on blindsight by Weiskrantz, and previous neuroscientif ...

Working Memory
Working memory is a cognitive system with a limited capacity that can Memory, hold information temporarily. It is important for reasoning and the guidance of decision-making and behavior. Working memory is often used synonymously with short-term memory, but some theorists consider the two forms of memory distinct, assuming that working memory allows for the manipulation of stored information, whereas short-term memory only refers to the short-term storage of information. Working memory is a theoretical concept central to cognitive psychology, neuropsychology, and neuroscience. History The term "working memory" was coined by George Armitage Miller, Miller, Eugene Galanter, Galanter, and Karl H. Pribram, Pribram, and was used in the 1960s in the context of Computational theory of mind, theories that likened the mind to a computer. In 1968, Atkinson–Shiffrin memory model, Atkinson and Shiffrin used the term to describe their "short-term store". The term short-term store was the na ...

Modality Effect
The modality effect is a term used in experimental psychology, most often in the fields dealing with memory and learning, to refer to how learner performance depends on the presentation mode of studied items. Description Modality can refer to a number of characteristics of the presented study material. However, this term is usually used to describe the improved recall of the final items of a list when that list is presented verbally in comparison with a visual representation. The effect is seen in free recall (recall of list items in any given order), serial recall (recall of list items in the order of study), short-term sentence recall (recall specific words from sentences with similar meanings) and paired associate recall (recall of a pair from presentation of one of its members). For paired associates, the effect is limited to an increased probability of recall for the final 2 or 3 pairs studied. In free recall and serial recall, the modality effect is seen as simply an exaggera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serial-position Effect
Serial-position effect is the tendency of a person to recall the first and last items in a series best, and the middle items worst. The term was coined by Hermann Ebbinghaus through studies he performed on himself, and refers to the finding that recall accuracy varies as a function of an item's position within a study list. When asked to recall a list of items in any order ( free recall), people tend to begin recall with the end of the list, recalling those items best (the recency effect). Among earlier list items, the first few items are recalled more frequently than the middle items (the primacy effect). One suggested reason for the primacy effect is that the initial items presented are most effectively stored in long-term memory because of the greater amount of processing devoted to them. (The first list item can be rehearsed by itself; the second must be rehearsed along with the first, the third along with the first and second, and so on.) The primacy effect is reduced when it ...

Dysarthria
Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system and is characterized by poor articulation of phonemes. It is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words. It is unrelated to problems with understanding language (that is, dysphasia or aphasia), although a person can have both. Any of the speech subsystems ( respiration, phonation, resonance, prosody, and articulation) can be affected, leading to impairments in intelligibility, audibility, naturalness, and efficiency of vocal communication. Dysarthria that has progressed to a total loss of speech is referred to as anarthria. The term ''dysarthria'' was formed from the Greek components ''dys-'' "dysfunctional, impaired" and ''arthr-'' "joint, vocal articulation". Neurological injury due to damage in the central or peripheral nervous system may result in wea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
