Memory 2 | The working memory model Flashcards
AO1 What is the central executive in the Working Memory Model?
The central executive is the component that allocates attention to tasks and coordinates the activities of the slave systems it has limited capacity and no storage.
AO1 What is the phonological loop in the Working Memory Model?
The phonological loop is a slave system that processes auditory information it consists of the phonological store inner ear and the articulatory control system inner voice and has a limited capacity.
AO1 What is the visuo-spatial sketchpad in the Working Memory Model?
The visuo-spatial sketchpad is a slave system that stores and manipulates visual and spatial information it has a limited capacity.
AO1 What is the episodic buffer in the Working Memory Model?
The episodic buffer integrates information from the slave systems and long-term memory into a single memory trace it has limited capacity and is a temporary store.
AO1 What is the coding of the phonological loop?
The phonological loop codes information acoustically based on sound.
AO1 What is the coding of the visuo-spatial sketchpad?
The visuo-spatial sketchpad codes information visually and spatially.
AO1 What is the capacity of the phonological loop?
The capacity of the phonological loop is limited to around two seconds worth of what you can say.
AO1 What is the capacity of the visuo-spatial sketchpad?
The visuo-spatial sketchpad has a limited capacity of around 3 to 4 objects.
AO1 What is the capacity of the episodic buffer?
The episodic buffer has a limited capacity but it is not precisely specified.
AO3 What AO3 point supports the WMM using dual-task studies?
Baddeley and Hitch found participants struggled more with two tasks that used the same slave system compared to two tasks using different systems supporting the idea of separate stores for verbal and visual information.
AO3 What AO3 point challenges the central executive in the WMM?
The role of the central executive is unclear and lacks detail some researchers suggest it may consist of multiple components rather than a single unitary store.
AO3 What AO3 point supports the WMM using brain imaging?
Brain scans show that different areas of the brain are active when processing verbal tasks compared to visual tasks supporting the idea of separate components such as the phonological loop and visuo-spatial sketchpad.
AO3 What AO3 point criticises the WMM for complex tasks?
The WMM does not fully explain higher-level cognitive processes like problem-solving and decision-making meaning it may not account for all aspects of working memory.
