Working memory- Memory Flashcards
Who developed the working memory theory and which store does it provide evidence for ?
- Baddeley
- short term memory
What is the central executive?
- info enters the mind for processing
- ATTENTIONAL PROCESS that monitors incoming data
- makes decisions
-directs other slave systems - limited storage
What is the phonological loop?
what 2 parts is it subdivided into?
- deals with auditory info
- subdivided into:
–> phonological store= stores words you hear
–> articulatory process= allows maintenance rehearsal (repeating sounds/ words to keep them circulating in the working memory)
What is the visuo-spatial scratch pad?
what is it subdivided into?
- rehearses info and deals with visual information
- ‘mental pictures’ are held here
- limited capacity
- subdivided into:
–> visual cache= stores visual data
–> inner scribe= records the arrangement of objects in the visual field
What is the episodic buffer?
- temporary information store
- integrates visual, spatial and verbal info processed by other stores
- limited capacity
- links the working memory to the LTM and wider cognitive processes such as perception
Describe research evidence for the working memory:
PROCEDURE
BROOKS
- showed ppts a block capital with an asterisk next to the bottom left corner
- asked to visualise moving the asterisk clockwise around the letter , whilst saying yes or no when indicating whether at each corner they came across, the line was on the top or bottom of the letter
- 2 different response conditions: one simply saying yes or no, other was having to point to a sign saying either yes or no located in the room
- time taken to complete the mental trip around the letter was timed
Research into WM,
describe the results and conclusions
results= ppts who had to point to a sign took longer to complete the mental trip than those saying yes or no out loud
conclusions=
-task of processing uses the visa-spatial scratch pad, but articulating the response doesn’t so it can happen relatively quickly
- having to point to a sign uses the visuo-spatial scratch pad whilst visualising can overload the limited capacity of the visa-spatial scratch pad
GREATER DEMAND ON THE LIMITED CAPACITY OF THE VISUO-SPATIAL SCRATCH PAD
AO3 working memory
- practical application, eg counting sheep helps treat insomnia as it uses the phonological loop which blocks information that may be keeping you awake
- the central executive does the most but we know the least about it, difficult to design tasks that use only the CE
- studies lack ecological validity as most of the evidence for this theory has been produced within a lab, could be argued that it lacks in what it claims to explain: MEMORY IN EVERYDAY SETTINGS
