WMM Flashcards
Who made the WMM
Baddeley and Hitch
What is the central executive
-A suspensory role that monitors and allocates data to the slave systems
-It’s also used in mental arithmetics and problem solving
-limited capacity as it cannot attend to many things at once
-codes modality free (dependant on the sense)
What is the visual spatial sketchpad (VSS)
Is used for planning visual / spatial tasks.
-The visual data either goes to the visual cache or the inner scribe
-the visual cache stores the visual data
-the inner scribe provides a rehearsal mechanism by recording the arrangement of the visual field
- It has a capacity of 3-4 objects
- It codes in visual information
What is the phonological loop
- It processes auditory information
-The information either goes through the phonological store or the articulatory process
-phonological store stores speech for brief periods
-articulatory process is linked to speech production and is used to rehearse and store verbal info from the phonological store
-capacity of 2 sec
-codes acoustically
What is the episodic buffer
Added in the 2000’s by Baddeley
-It’s the temporary store for information received by the CE
-It integrates info from all 3 slave systems to make episodes
-Limited storage capacity and transfers the information into the LTM
-capacity is 4 chunks
Coding is modality free
AO3 strength of WMM
Baddeley et al
-Participants had more difficulty doing 2 visual tasks eg. Tracking a light and describing the letter F. Than doing both a visual and verbal task
-Competing slave systems
-Increasing the external validity
AO3 Weakness WMM
Baddeley discovers the CE in 2000 stating it’s the most important but least understood
-decreases the external validity of the study as it’s no longer reliable
AO3 strength of WMM clinical ev
Shallice and Warrington - KF
KF has a bad STM ability for verbal info but can process visual info normally
-Increased external validity
