Visuo spatial sketchpad8/1/2023 Spatial memories are said to form after a person has already gathered and processed sensory information about her or his environment. This allows one to remember where an object is in relation to another object for instance, allowing someone to navigate through a familiar city. Spatial memory is a cognitive process that enables a person to remember different locations as well as spatial relations between objects. Tasks which employ short-term memory include learning, reasoning, and comprehension. Short-term memory (STM) can be described as a system allowing one to temporarily store and manage information that is necessary to complete complex cognitive tasks. Many methods are used for measuring spatial memory in children, adults, and animals. Research indicates that there are specific areas of the brain associated with spatial memory. Spatial memory has representations within working, short-term memory and long-term memory. In both humans and animals, spatial memories are summarized as a cognitive map. A rat's spatial memory is needed to learn the location of food at the end of a maze. A person's spatial memory is required to navigate around a familiar city. Spatial memory can also be divided into egocentric and allocentric spatial memory. Spatial memory is necessary for orientation in space. In cognitive psychology and neuroscience, spatial memory is a form of memory responsible for the recording and recovery of information needed to plan a course to a location and to recall the location of an object or the occurrence of an event. Studies have indicated that visuospatial sketchpad might actually be containing two different systems: one for spatial information and processes and the other for visual information and processes.Spatial memory is required to navigate through an environment. It is important in spatial orientation and solving visuospatial problems. This construct according to Baddeley enables temporary storing, maintaining and manipulating of visuospatial information. (For example, repeating “A red car is on the lawn.”) It can also help in memorizing information from the visuospatial sketchpad. Verbal information seems to be automatically processed by phonological loop and it also plays an important, maybe even key role in language learning and speech production. Processor which maintains sound information in the storage by vocal or sub vocal repetition. It serves as the storage component of central executive, or otherwise information integration wouldn't be possible.Īccording to Baddeley, phonological loop consists of two components : a sound storage which lasts just a few seconds and an articulatory These functions also include communication with long-term memory and connections to language understanding and production centers.Įpisodic buffer has the role of integrating the information from phonological loop and visuospatial sketchpad, but also from long-term memory. Sequencing, updating, maintenance and integration of information from phonological loop and visuospatial sketchpad. Central executive's functions include attention and focusing, active inhibition of stimuli, planning and decision-making, It is still unclear whether it is a single system or more systems working together. This model was later revised and improved by Baddeley but also contributed by other authors, which resulted in additional component of episodic buffer in year 2000 and more detailed functions and analysis of other components, as described in table below. Baddeley and Hitch suggested working memory is composed of three parts: the central executive, a system that controls the phonological loop (a subsystem for remembering phonological information such as language by constant refreshing through repetition in the loop), and the visuospatial sketch pad (a subsystem for storing visual information). The new term working memory was supposed to emphasize the importance of this system in cognitive processing. \)īased on experiments demonstrating connections between LTM and STM, as well as experiments indicating that STM consists of more components, Alan Baddeley and Graham Hitch proposed a multi-component working memory model in 1974.
