The Working Memory Model Flashcards
Who made this model
BRADDLEY and hitch
What does it aim
Explains how one aspect of memory (short-term memory) is organised and how it functions
Concerned with part of mind that is active when we are temporarily storing and manipulating infoma
Central executive
An additional process that monitors incoming decisions and allocates slave systems to tasks
Limited storage capacity
Phonological loop
One of the slave systems
Deals with auditory information
Phonological store - stores words you hear
Articulatory store - allows maintenance rehearsal to keep info in working memory (capacity is 2 seconds)
Visuo-spatial sketchpad
Second slave system - stores visual info
Limited capacity (3-4 objects)
Visual cache - stores visual data
Inner scribe - records the arrangements of objects in the visual field
Episodic puffer
Third slave system
Temporary store for info
Maintain sense of time sequencing (recording event)
Storage component for central executive - Limited capacity of 4 chunks
Links memory with LTM
Ao3 - strength - clinical evidence
P - supports model
E - patient suffered from brain damage and had poor STM ability for verbal info but could process visual info (digits not sounds) meaning phonological loop is damaged leaving other areas intact
E - supports existence of separate visual and acoustic store
Ao3 - Strength - dual task performance
P - duel task performance supports existence of visuo spatial sketch pad
E - study shows that participants had more difficulty doing two visual tasks than visual and verbal tasks at the same time. This is because both visual tasks compete for the same slave system whereas different tasks don’t
E - means there must be a separate slave system that process visual input
A03 - limitation - lack of clarity over central executive
P - cognitive psychologist suggest this component is unsatisfactory and doesn’t explain anything
E - Braddley explained the central executive is most important but least understood component of model. Some psychologists believe it may consist of separate components
E - there’s not enough evidence as model isn’t fully explained, may not be real
Ao3 - limitation - musical memory
P - criticised that model fails to take music into account
E - we are able to listen to instrumental music without imparting performance on other acoustic tasks
E - shows the model is not very reliable
