The working model of memory is a model of short term memory which was developed from experimentation and observation by Baddeley and Hitch in 1974. They developed this as they didn’tt believe that short-term memory was as simple as being only one store. The WMM consists of 3 main stores‚ the central executive‚ the phonological loop and visuo-spatial sketchpad. The central executive can store information for a brief period of time and has limited capacity‚ it is needed to perform a number of tasks

Outline and evaluate the working memory model (12 marks) Baddeley and Hitch proposed that memory has 4 components. The central executive‚ phonological loop‚ visuospatial sketchpad and the episodic buffer. The central executive decides how to share out and direct attention to incoming information. The phonological loop can be thought of as a maintenance rehearsal mechanism for retaining verbal information. It is sub-divided into two other components‚ the phonological store (inner ear)‚ which holds

Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called the working memory model. The working memory model consists of four components. The central executive which controls and co-ordinates the operation of two subsystems‚ the phonological loop and the visuo-spatial sketchpad. The central executive controls attention and coordinates the actions of the other components‚ it can briefly store information‚ but has a limited capacity. The phonological loop consists

short-term memory (STM) provided by the Multi-Store Model was far too simple. Following the Multi-Store Model‚ it is believed that STM holds limited amounts of information for short periods of time with relatively little processing‚ it is believed to be a unitary store. This means that due to its single store it has no subsystems‚ unlike the Working Memory Model which has many subsystems. This proves that the Working Memory is not a unitary store. Working Memory is STM. In contrast to the Multi-Store

Outline and Evaluate the Working Memory Model The working memory model is a theory for how short-term memory works‚ and an expansion of the views expressed in the MSM theory. Baddeley and Hitch in 1974 felt that STM was not just one store but a collection of different stores. These concepts lead them to form a model which consists of three slave systems; the central executive‚ the phonological loop and the visuo-spatial sketchpad. They used the phrase ‘working memory’ to refer to the division of

Outline and evaluate the working memory model (12) The working memory model (WMM) suggests that there are three main components to human memory. The central executive is the key component of working memory and is what directs attention to particular tasks‚ deciding which ‘resources’ (being the phonological loop and visual-spatial sketchpad) are allocated to which tasks. The central executive has a very limited capacity however‚ and can’t attend to too many things at once. The phonological loop

Outline and evaluate the working memory model The working memory model is the part of the short term memory which is governed by the ‘central executive which monitors and coordinates the operation of the store systems; Phonological loop and visuo – spatial sketchpad. The phonological loop allows sounds to be stored for brief periods. The visuo spatial sketchpad allows visual and spatial information to be stored for brief periods. The two slave systems within the WMM are completely separate and can

Outline and Evaluate Models of Memory. (12 Marks) There are roughly four models of memory in total‚ but two stand out and are used in this particular specification. Atkinson and Schifrin’s (1968) “Multi-Store Model” is one of them. Their model suggests that the memory consists of three stores‚ a sensory store‚ a short-term store and a long-term store; all three have a specific and relatively inflexible function. It stressed that information for our environment such as the visual or auditory

Essay Describe and evaluate the synaptic homeostasis model of sleep The synaptic homeostasis model of sleep (Tononi & Cirelli‚ 2003) explains memory consolidation as a by-product of synaptic downscaling that occurs during sleep. This essay will describe the synaptic homeostasis model of sleep and evaluate how valid its predictions are in the face of empirical research. According to this model‚ synaptic potentiation is associated with the homeostatic regulation of slow wave activity‚ which

‘Outline and evaluate the working memory model’ The working memory model was proposed by Baddeley and Hitch in 1974. This was an alternative to the multi-store model because they believed it was too simplistic and did not explain how memories are transferred into the long term memory without rehearsal which can be supported by flashbulb memories e.g. the death of princess Diana. The working memory model focuses on the short term memory and suggests that unlike the multi-store model‚ there is more
