1.2. Working Model Of Memory Flashcards
What are the three things said about the WMM?
- Deals with STM only
- Active processor -> stores work together to process information
- Dual tasking -> doing two things at once (as long as you use separate stores)
What is the main purpose of the central executive?
- The controller
- Delegates info to the slaves
- Deals with reasoning and problem solving
Capacity of the central executive
Limited
Coding of the central executive
Modality free -> deals with all coding
What is the main purpose of the articulatory loop?
- Inner voice
- Prepares speech
Capacity of the articulatory loop
As long as it takes to say something
Coding of the articulatory loop
Acoustic
What is the main purpose of the phonological store?
- Inner ear
- Auditory loop
Capacity of the phonological store
2 seconds
Coding of the phonological store
Acoustic
What is the main purpose of the visuospatial sketchpad?
- Stores visual and spatial info when required
- Inner eye
- Internal map
- Allows you to know where you are in your environment and how close you are to things
Capacity of the visuospatial sketchpad
- Limited capacity -> according to Baddeley it’s three or four things
Coding of the visuospatial sketchpad
Visual cache: stores visual info
Inner scribe: records the arrangement of objects in a visual field
Hitch and Baddeley (1976)
Aim: to test if you can use the same stores for 2 different tasks
- Investigated dual tasking in the STM
- 2 groups of ppts had to do 2 tasks at once using different sub stores
Group 1: task 1=CE, task 2=CE+AL -> struggled
Group 2: task 1=CE, task 2=AL -> fine
- Results: we can dual task as long as we are using different sub routines
Strength: KF
+ KF had a motorbike accident, upon waking he struggled verbally, not visually and could make new LTMs
+ According to this model, the damage only occurred in the “Articulatory loop”
+ MSM was unable to explain that due to its explanation of STM being unitary
