Working memory model essay Rating:
The working memory model is a theoretical framework that explains how the human brain stores and processes information. It was first proposed by psychologist Alan Baddeley and colleagues in the 1970s as an alternative to the traditional model of memory, which described memory as a single, unified system.
According to the working memory model, the brain has a limited capacity for processing and storing information in the short-term. This information is held in a temporary, active memory system called the "central executive," which controls the flow of information between the other two components of the working memory system: the phonological loop and the visuospatial sketchpad.
The phonological loop is responsible for storing and processing verbal information, such as speech and language. It consists of two subcomponents: the phonological store, which holds verbal information in a auditory form, and the articulatory rehearsal process, which allows us to repeat and rehearse this information in our minds.
The visuospatial sketchpad is responsible for storing and processing nonverbal, visual information. It allows us to visualize and manipulate spatial relationships, such as the layout of a room or the movement of objects.
The working memory model has been influential in our understanding of how the brain processes and uses information. It has been used to explain a wide range of cognitive phenomena, including the effects of distraction on memory, the role of rehearsal in memory retention, and the relationship between working memory and long-term memory.
One of the key strengths of the working memory model is its ability to account for the limited capacity of the human brain. It explains why we can only hold a small amount of information in our minds at any given time and why we have difficulty multitasking or switching between tasks.
However, the working memory model has also been criticized for its lack of explanatory power in certain areas. Some researchers have argued that it does not adequately explain the role of emotions and motivation in memory, and that it does not fully capture the complexity of the human memory system.
Despite these criticisms, the working memory model remains an important and widely accepted framework for understanding how the brain processes and stores information. It has shaped our understanding of memory and has had a significant impact on the field of cognitive psychology.
Working Memory Research Essay
Finally, the conclusion will outline speculations on further developments and comments on the value of attempting to apply the 2000 model of working memory beyond the laboratory studies, to everyday life. Hallucinations can occur in any sensory modality. The working memory model has four components: the central executive which acts as a leader for the other three stores by allocating attention and monitoring the activities of the other components. The storage process involves the retention of encoded information over time. Liebermann criticized the WM model as the visuospatial sketchpad VSS implied that all spatial information was first visual. Soon after they added a third memory store and …show more content… His study on word length effect comprised that participants had to read out as many words as they could than recall it.
Essay on Baddeley and Hitch’s Working Memory Model
The first model is the multi store model. KF suffered brain damage from a motorcycle accident that damaged his STM. Finally, the episodic buffer. The validity of the model has been questioned as research studies have tended to concern only semantic memory, therefore the results and the model may be relevant to only this kind of memory rather than explaining memory for events in the past as well. It can recall both two-dimensional and three-dimensional images. They allow us to organise our behaviour, help us to plan activities, sustain attention, complete tasks and achieve long term goals. Short-term memory is used for holding small pieces of information over a short period of time and the working memory is part of the short-term memory that deals with immediate processes and scientists use it to refer to sustained neural activation.
Memory can be defined as the persistence of learning over time via the encoding, storage, and retrieval of information. However, dissecting the subcomponents of the sketchpad has proved more challenging than separating the phonological loop. This paper will provide an overview of the working memory model, including its general process of functioning and how false memories can form during its operation. Through fMRI it has become easier to quantify the degree to which abnormalities are influenced by outside factors other than drug exposures Norman et al. Participants did an interference task, counting backwards between presentation and recall to prevent rehearsal. Patients with Alzheimer disease proved a noticeable reduction in the mixed condition, but none in the normal tasks.
The multi-store model is too simple and fails to reflect the complexity of the human memory. In addition, memory span tasks support the existence of the articulatory loop showing that task ability heavily depends on a Atkinson And Shiffrin's Theory Of Memory Memory providing the awareness of our existence among people is a skill that needs to fulfil its function. The lemma contains the syntax, or the grammatical context of the word, in addition to the semantics, or meanings of the words. Additionally, we still know relatively little about how the brain actually stores this information and utilizes it properly. When a disorder related to any of these elements is present, the ability to communicate may be impaired. This model consists of three primary components: the central executive, the phonological loop, and the visuo-spatial sketchpad. The mental function of retaining information about stimuli, event, images, ideas, etc.
On the other hand the visuo-spatial sketchpad displays visulal and spatial 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. It was discovered as an alternative to the multi-store model of memory. WM plays a crucial role in manipulating and holding information for complex tasks such as comprehension, learning, and reasoning. While we think, imagine or learn something, we create the internal representation in our mind which we always call them as concepts or schemas. It usually operates for around 20-30 seconds and is capable of storing larger amounts of information as long as it is grouped into meaningful chunks of about five to eight digits.
We have two parts of memory which are the long-term memory and short-term memory. Broadly speaking, there are two fundamental memory errors that occur in everyday life. The phonological loop is sub-divided into 2 smaller components, the articulatory control system, where information is rehearsed sub vocally or in the inner voice and the phonological store where speech is held for a very brief duration in the inner ear. In studies of brain-damaged patients, individuals with impaired short term memory show better recall for visually presented digits than for auditory presented digits. McDonald 1998 suggested using different tasks and different materials in her study on individuals with Alzheimer disease. Experiments have been inducted by Sperling using a tachistoscope to prove the duration of the sensory registry and evidence from Peterson and Peterson about the duration of the STM memory by giving participants trigrams, the evidence for encoding in the LTM is shown by Baddeley 1966 who investigated coding in the STM and LTM memory.

The first model is the multi store model. So far… The working memory model has replaced the idea of a unitary component STM with a multi-component. Working memory is a part of the human memory system with a limited capacity. Information enters via our senses sight, smell, sounds, taste and touch into the sensory store. These 3 components are separate, but they also interrelate. Does Human Memory Work Like a Tape Recorder 2.

Making Sense of Our World: The Role of Representation. STM in the modal model of memory was considered to be a passive buffer store, which holds information for about, say up to 30 seconds. Knowing that Veterans typically have a trust issue when it comes to personal. Hence, the amount of information retained is limited and follows different pathways. The phonological loop consists of two parts, the articulatory control system and the phonological store.
The central executive, as the name implies, is the primary component of the working memory system; every other component is subservient to it. Because this period covers everything from primary to high school, there is no way for me to accurately remember all the events in order. The working memory model theory was introduced by Baddeley and Hitch as an alternative option to the multistore model version of the short term memory. This essay will evaluate two models of theories of memory. Through use of working memory tasks, evidence shows that children prenatally exposed to tobacco experience more activation in the inferior parietal regions of the cortex whereas children not exposed showed activation in the bilateral inferior frontal region of the cortex instead Bennett et al. The results showed greater right frontal activation for integrated information, with unintegrated retention showing more latter activation of areas previously implicated in verbal and spatial working memory. It quickly gained a lot of attention from the scientific community, which proceeded to further research the multi-store model.
