memory- WMM Flashcards
who proposed the Working Memory Model?
Baddeley and Hitch (1974)
what does the WMM show?
-model of STM
-WMM is concerned with the ‘mental space’ that us active when working on an arithmetic problem, etc
diagram of the working memory model
what is the role of the central executive in the WMM?
-supervisory role- monitors incoming data, directs attention and allocates subsystems to tasks
what’s the capacity of the central executive?
very limited storage capacity
what is the role of the phonological loop in the WMM?
-deals w/ auditory info and preserves the order in which info arrives
what does the phonological loop consist of (WMM)?
-phonological store
-articulatory control system
what does the phonological store do?
stores words you hear
what does the articulatory control system do?
allows maintenance rehearsal (repeating sounds to keep them in WM while they are needed)
what is the role of the visuo-spatial sketchpad in the WMM?
stores visual and/or spatial info when required
who divided the visuo-spatial sketchpad and what did they divide it into?
Logie (1995):
-visual cache- stores visual data
-inner scribe- records arrangement of objects in visual field
what is the role of the episodic buffer in the WMM?
-temporary storage
-integrates visual, spatial and verbal info from other stores
-maintains sense of time-sequencing- recording events that are happening
-links to LTM
ao3 WMM- clinical evidence
-Shallice and Warrington (1970) studied patient KF who had a brain injury
-his STM for auditory info was poor (damaged PL) but he could process visual info normally (intact VSS)
-supports WMM view that there are separate visual and acoustic memory stores
ao3 WMM- counterpoint for clinical evidence
-KF may have had other impairments which explained performed poor memory performance, apart from damage to his PL
-challenges evidence from clinical studies of brain injury
ao3 WMM- dual task performance studies support the VSS
-Baddeley et al. (1975) p’s found it harder to carry out two visual tasks at the same time than do a verbal and visual task together.
-this is bc both visual tasks compete for the same subsystem (VSS). theres no competition with a verbal and visual task
-so, must be a separate subsystem that processes visual input (VSS) and also a separate system for verbal processes (PL)
ao3 WMM- lack of clarity over the CE
-Baddeley (2003) said CE was the most important component but the least understood component of working memory
-there must be more to the CE than just being ‘attention’ e.g. its made up of separate subcomponents
-so CE is an unsatisfactory component and this challenges integrity of the model
