Memory: The Working Memory Model Flashcards
What is the working memory model??
A representation of STM. Suggests that STM is a dynamic processor of different types of info using sub-units coordinated by a central decision-making system!
What does the Central Executive do??
Coordinates activities of the 3 subsystems ion memory.
Attentional process that monitors incoming data, makes decisions and allocates subsystems to tasks!
What is the capacity of the Central Executive??
Limited
What does the Visuospatial sketchpad do??
Processes visual and spatial information
What is the capacity of the Visuospatial sketchpad??
Limited. Baddeley in 2003 said it’s about 3-4 objects
Who and when subdivided the Visuospatial sketchpad??
And what was it divided into??
Logie 1995
- Visual cache (storing visual data)
- The inner scribe (records arrangement of objects in visual field)
What does the Episodic Buffer do??
Brings together information from other subsystems to create one singular memory!
Provides a bridge between working memory and LTM
Maintains sense of time-sequencing
Who added the Episodic Buffer??
Baddeley in 2000
What’s the capacity of the Episodic Buffer??
Limited of 4 chunks
What does the Phonological Loop do??
Processes information in terms of sound
Contributes to our learning of sounds of language
Preserves order in which information arrives
What are the 2 components of the Phonological Loop??
Phonological Store (stores words we hear)
Articulatory Process (Allows maintenance rehearsal -> A constant loop in working memory of what we need to remember in that short moment)
What is the Clinical Evidence evaluation point??
Shallice & Warrington (1970)
Case study of Patient KF with brain damage
- Poor STM ability for verbal information
- Could process visual information normally
Suggests: Only phonological loop was damaged
Supports Model: Evidences existence of separate visual & acoustic store existing
What’s the issue with the Clinical Evidence evaluation point??
Concerns unique cases with brain-damaged patients who’ve had traumatic experiences
What is the Dual Task Performance evaluation point??
Baddeley et al (1975)
Ppts had more difficulty doing 2 visual tasks than doing 1 visual and 1 verbal at the same time
Supports: 2 visual tasks would be competing for same slave system
Must be separate slave system that processes visual info
What is the Lack of Clarity of the Central Executive evaluation point??
- Many cognitive psychologists say the CE is unsatisfactory and doesn’t really explain anything
- Baddeley (2003): Said it’s most important but least understood
- Hasn’t really been fully explained
