Baddeley And Hitch: The Classic Model Of Working Memory
The classic model of working memory was proposed by Baddeley and Hitch in 1974 (Courtney, Ungerleider, Keil & Haxby, 1996). Working memory is responsible for the maintenance and controlled manipulation of information before it can be recollected (Aben, Stapert & Blokland, 2012). Baddeley and Hitch had proposed that working memory consisted of three key components; the central executive, phonological loop, and the visuospatial sketchpad (Aben, Stapert, & Blockland, 2012). The central executive is primarily responsible for reasoning, decision making, and the coordination of operations of the phonological loop and visuospatial sketchpad, and dual-task performance (Logie, 1995). The phonological loop is responsible for the storage and manipulation …show more content…
In past studies, research has demonstrated that participants often automatically adopt strategies of verbal encoding to remember the identity of objects, even when relatively ‘nonverbalisable’. (Postle, D’Esposito & Corkin, 2005). The theory of simultaneous multiple encoding describes the representations of objects in working memory as semantic codes, that is, words encoded according to the semantic properties of the object. Postle, D’Esposito and Corkin (2005) state that verbal information associated with the object by the participant may be applied in addition to its visual features. It was found that the automaticity of verbal coding failed to apply to all visually presented information, including location (Postle, D’Esposito & Corkin, 2005). Postle, D’Esposito and Corkin (2005) suggested that location is assumed to be represented in a nonverbal analog code. Additionally, studies conducted by Simmons (1996) suggested that memory for objects was substantially worse than for location because object working memory was sensitive to experimental manipulations that aimed to suppress verbal encoding strategies (Postle, D’Esposito & Corkin, 2005). While, the memory code used to remember location is nonverbal, therefore, it is not affected by verbal

Effects Of Unconscious Transference On Eyewitness Recall
918 Words | 4 PagesUnconscious transference has been found to affect eyewitness recall. Unconscious transference refers to the misidentification of an innocent person as the perpetrator due to seeing them in another context e.g before or when the event occurred. This occurs because of the way our brain retrieves information. In order to recall an event we have to reconstruct information using nerve pathways that were associated together during the event.
Oliver Sacks 'The Man Who Mistook His Hat For His Wife'
1264 Words | 6 Pageson the effects of dementia on working memory. The study was based on a model by Baddeley and Hitch in 1974. The model consists three parts; the central executive, which “serves as a middleman” (Baddeley & Hitch, 1974), and controls the flow of information for the two other systems; the visuospatial sketchpad, and the phonological loop. The visuospatial sketchpad is responsible for storing visual and spatial information, whereas the phonological loop stores verbal content. Kensinger found that when the victim is suffering from dementia, in this case, Alzheimer’s (which is a reduction in memory that gradually progresses), his “semantic memory is compromised” (Kensinger et al., 2004), which is the knowledge of words and actions.

663 Words | 3 PagesMoreover, “a behavioural syndrome results showing not only semantic-memory impairment but also particular difficulty remembering past events as personal happenings” (Tulving, 1989). Lastly, in Endel Tulving’s conclusion to his article he states “traditionally held views about the unity of memory are no longer tenable. A more appropriate view seems to be that of multiple memory systems. Remembering one’s past is a different, perhaps more advanced, achievement of the brain than simply knowing about it” ( Tulving,
John Sweller's Cognitive Load Theory
777 Words | 4 PagesCognitive Load Theory (CLT), was originally developed by John Sweller in 1988 (Sweller 1988), in the fields of education and instructional design. It is based on the concept that there are three interdependent systems of the cognitive load: memory systems (sensory, working and long-term memory; LTM), learning processes and types of cognitive load imposed on working memory (WM).CLT has particular relevance to medical education and it facilitate to understand how and why learners in the health professions struggle with mastering the concepts and developing toward expertise because the tasks are complex and may impose a cognitive load that surpasses the WM capacity of the learner. CLT and the human memory system are interdependable and builds
Video Analysis: Semantic Memory And Episodic Memory
532 Words | 3 PagesThe different stores of long-term memory consists of explicit memory, which is knowledge, or memories that an individual can recall consciously. And that is broken down into two different stores called semantic memory and episodic memory. Semantic memory is considered to be the knowledge of facts and concepts regarding the universe. Episodic memory is firsthand personal of accounts that we have experienced similar to an important event that may have occurred in one’s life. There is also implicit memory, which is influences of experiences on behavior.
Schema Theory Of Eyewitness Testimony

This can also be seen in Allport and Postman’s study where participants were asked to recall details of a picture. The participants stated that the black man was the person who was holding the razor when in reality it was the white man. This demonstrated that our memories are actively being
The Importance Of Collective Memory And Cultural Identity
963 Words | 4 PagesThere are other movements, beside physical body movement, allowed by our brain of which individuals are not conscious, or at least not fully conscious; namely, the action of remembering and forgetting. According to Pierre Nora memory “remains in permanent evolution, open to the dialectic of remembering and forgetting” (8) process which he claims to be “unconscious”. It is given to this dialectic, as Jan Assmann mentions in his essay Collective Memory and Cultural Identity that ““the survival of the type” in the sense of a cultural pseudo-species is a function of the cultural memory…” (126), which means: first, that the identity of a place is not inherited through genes; and second, that it depends on individuals’ conscious effort to maintain it. Individual memory or communicative memory as Assmann calls it “does not extent more than eighty to (at the very most) hundred years…”
Essay On The Construction Of Memory
712 Words | 3 PagesMemory, as we understand it, is an exclusively human characteristic and of fundamental importance to our species. It is in the act of remembering that we build ourselves, not only when we remembering something but also in the way that we do it. Thus, it can be said that remembering is not restricted to an act alone, but any thing that we remember is attributed some symbolic value, which, added to the other life experiences of the person, to his ideology and the collective community's memory in which it is inserted, creates something that goes beyond simply remembering. Memory is at the same time an act of remembering a specific data, like a telephone number, but at the same time, it is a construction created from the idiosyncrasy of those who remember, added to the external influences of their environment. About the interaction between subject and ambient in the construction of memory
Attention, Memory And Memory Analysis
1614 Words | 7 PagesAccording to Richards (2004), attention can be stated as the selective improvement of some behavior to the detriments of other behavior. Attention is also an important skill that significantly influences an individual’s ability to complete daily tasks safely (Jefferson Health System, n.d). Attention and working memory are strongly linked and the relationship between working memory and attention suggest a close connection, even isomorphism (Fougnie, 2008). Content of working memory and attention often overlap as working memory capacity can be increased with attention (Turner & Engle, 1989). The ability to selectively process information (attention) and to retain information in an accessible state (working memory) is critical aspects of our cognitive capacities (Fougnie,
Feature Matching Theory
1553 Words | 7 PagesNumerous theories concerning how we identify and recognise objects are debated today. Template matching, feature matching, and structural analysis, all theories of object recognition, suggest how our brains interpret sensory input through the visual cortex and connect this input to meaning. To recognise an object, the brain matches the information passed through the retina to existing knowledge stored in our memory. Perhaps, when presented with an object, the brain flicks through stored image templates (Tarr & Vuong, 2002) that ‘represent known objects’ (Edelman & Bulthoff, 1992, p. 2385) until a match to the stimulus is found, causing you to recognise the object.
