The working memory model
Karten in diesem Stapel (7)
- 1working memory modelrepresentation of short term memory that suggests that STM is a dynamic processor of different types of information using sub-units coordinated by a central decision making system
- when storing and manipulating information e.g math problems
-four main components with different capacity and coding - 2central executivecomponent of WMM which is an attentional process which monitors incoming data and allocates slave systems to tasks
- limited storage capacity - 3phonological loopdeals with auditory information and preserves the order in which the information arrives
subdivided into: phonological store - stores the words you hear and
articulatory process - allows maintenance rehearsal - 4visuo-spatial sketchpad (VSS)stores visual and spatial information when required e.g recalling how many windows your house has
subdivided into: visual cache - stores visual data and
inner scribe - records arrangement of objects in visual field - 5episodic buffer (temporary storage)integrates visual, spatial and verbal information from other stores
- maintains sense of time sequencing - recording events or episodes that are happening as it links to LTM - 6two strengths of the working memory model- dual task performance baddeley et al 1975 supports the visuo-spatial sketchpad
> participants find it more difficult to do two visual tasks than doing a visual and verbal task at the same time due to the competition for resources
> evidence for the existence of VSS
- support from brain scanning studies as braver et al 1997 did tasks involving the central executive while they were having a brain scan
> activity was seen in an area known as the prefrontal cortex
> evidence that the central executive may have a physical reality in the brain - 7Baddeley and Hitch 1974 working memory model
