The Working Memory Model

HideShow resource information
Who created the Working Memory Model?
Baddeley and Hitch 1974
1 of 18
Name the three sections of the WMM
1. Central executive 2. Visual spatial scratchpad 3. Phonological loop
2 of 18
Define the Central Executive
The 'manager', its main role is to control attention and coordinate the slave systems. It is able to store a very limited amount of information for a very limited time
3 of 18
Name two key features of the Central Executive
1. The 'boss' 2. Modality free
4 of 18
Define Episodic Buffer
A store in which a limited amount of information is held for later processing
5 of 18
Name two key features of the Episodic Buffer
1. Has limited capacity 2. Integrates information into a single 'episode'
6 of 18
Define the Visual Spatial Scratchpad
The 'inner eye', has a limited capacity and processes visual information. Evidence suggests that we use the scratchpad to manipulate images in our head
7 of 18
Name two key features of the Visuospatical sketchpad
1. The 'inner eye' 2. Deals with visual information such as shape, size and colour
8 of 18
Define the Phonological Loop
Also has a limited capacity and processes auditory information, but is made up of two parts
9 of 18
Name the two parts of the Phonological Loop
1. Phonological store 2. Articulatory loop
10 of 18
Name two key features of the Phonological Loop
1. Allows for sub-repetition of information 2.Deals with verbal material
11 of 18
Define the Phonological Store
The 'inner ear', auditory information enter memory here but can only be stored for around 2seconds if not passed through the articulatory loop
12 of 18
Name two key features of the Phonological Store
1. The 'inner ear' 2. Listens to the 'inner voice'
13 of 18
Define the Articulatory Loop
The 'inner voice', auditory information is rehearsed here subvocally (silently) in order to be remembered
14 of 18
Name two key features of the Articulatory Loop
1. The 'inner voice' 2. Has a capacity of 2 seconds
15 of 18
Give 2 strengths of the Working Memory Model
1. Clinical evidence from brain-damaged victims support the presence of separate parts of the STM 2. Provides explanations for many experimental findings that the Multi-Store Model cannot
16 of 18
Give 2 limitations of the Working Memory Model
1. There is no empirical evidence to support the presence of a central executive, this part of the model is theoretical only 2. The empirical evidence in support of the whole model, lacks ecological validity as it is laboratory based
17 of 18
Explain the case of KF
He suffered brain damage after a motorbike accident, Shallice and Warringtion showed that STM works independently of LTM. Interestingly his auditory memory was worse for letters and digits compared to meaningful sounds e.g ...ring ring...
