Alan Baddeley’s Multi-Component Model Of Working Memory: Features And Neural Evidence
The following study is going to visit literature used in Alan Baddeley’s multicomponent model of working memory. The model is a human proposed memory model that presents accurate primary memory. Besides, the working memory entails the mind found in an individual’s brain whereby they hold temporary information. Afterwards, they convert the collected data that has been stored in the memory to either permanent or temporary memory. There are for components that are involved in the working memory, and they are phonological loop, visual-spatial sketchpad, central executive and episodic buffer. The following section will discuss the four components, empirical review, and other insights found in the multi-component model of working memory.
The Four Components of the Working Memory
Phonological Loop
According to CITE phonological loop is an element of working memory model that deals with auditory as well as visual information. Besides, it is a temporary store of verbal information. It has two subdivisions, the phonological store as well as the articulatory rehearsal. The phonological store is linked with speech perception. Thus it is compared to the inner ear that receives as well as stores spoken words. More so, it holds speech sounds in the order that they are heard. The information can decay if it is not refreshed. The articulatory rehearsal is responsible for rehearsing information to avoid rapid dwindling in the phonological store. Don't use plagiarised sources.Get your custom essay just from $11/page
Visual-Spatial Sketchpad (VSS)
According to CITE visual-spatial sketchpad is an essential factor in the working memory function because it is accountable for storing plus processing data in visual, partial form, location and object speed in space. Visual-spatial sketchpad is divided into two types the visual as well as the spatial components. CITE the visual cache is used to store information on the form as well as colour. The inner scribe focuses on spatial as well as movement information. More so, the inner scribe rehearses data in the visual cache as well as transfers data to the central executive CITE. Overall, the visual-spatial sketchpad for temporary packing information on the look of things and it permits manipulation of images in mind. Besides, VSS recreates images on the bases of something we see currently or what we have seen lately.
Central Executive
According to CITE, the central executive is an essential component of the multi-component model. The primary responsibility of the central executive is monitoring as well as coordinating the slave system operation and the part to send the data. Also, the central executive guides attention plus provides priority to specific activities. Overall, the central executive is the most useful and essential component in the working memory.
The Episodic Buffer
According to, the episodic buffer is demarcated as a limited capacity reserve system that is responsible for information integration from numerous working memories as well as activating semantic and linguistic knowledge. The episodic buffer acts as a reserve store that communicates with long term memory as well as the working memory components. It is assumed that the central executive manages the episodic buffer. For this reason, the buffer is episodic to hold episodes where information is joined across space and extended through time. The overall episodic buffer is assumed to be feeding data and retrieving data.
Empirical Review
There are several ways one can hope to describe and explain cognitive abilities. The multi-component model of working memory has strongly influenced much of the research in the cognitive psychology working memory. By expanding the notion of passive short –term memory to an active system provides the basis for complex cognitive abilities. In this research, there is a reference of empirical data within empirical data within experimental cognitive psychology that has shaped the development of the multicomponent model and understanding of the capacities and properties of working memory. It is based mainly on dual-task that has yielded valuable information about the fractionation of working memory into independent stores and processes, the nature of representation in individual stores, the mechanisms of maintenance and manipulation and also the way components of working mind relate to each other. More so the way the working memory refers to each other and the role they play in different cognitive abilities. This review aims to present insights that have been enabled by experimental behaviour studies in cognitive psychology. Besides, the subject of working memory, like any other within cognitive neuroscience, can be approached from many different levels of description. Each level of description is a valid one and contributes importantly to a complete understanding of the phenomenon under investigation. It provides a glimpse into the structural underpinnings of the cognitive system, and computational cognitive neuroscience addresses the question of how the information processing is carried out, the role of cognitive psychology is to provide a detailed description of the properties and the capacities of the system. The result provides both a persuasive argument in support of the general concept of the working memory system as well as information that led to the formulation of a specific multi-component model. Baddeley and Hitch present the initial model proposed the existence of three functional component memory. The model is responsible for the storage and maintenance of information in a phonological form. At the same time, the visuospatial sketch pad was dedicated to the storage and preservation of visual and spatial data. The episodic buffer is assumed to be a limited capacity store that is capable of multi-dimensional coding that allows the binding of data to create integrated episodes.
The demands of the task. The participants can maintain spatial information either in the form of prepared eye movements or as perceptual memory of stimulus position.
We suggest that working memory has proved to be an essential part of the cognitive system providing the ability to maintain and manipulate information in the process of guiding and executing complex cognitive tasks. It can be fractionated into several independent subsystems, processes, and mechanisms. The subordinate components provide limited capacity memory stores that enable the representation and maintenance of information. Two of the subcomponents are domain-specific, providing the ability to hold phonological and visuospatial information in separate stores. A third subcomponent enables the integration of data into complex multi-modal representations linking working memory to long -term memory.
