Working memory model Flashcards
Who devised the WMM?
Baddeley + Hitch
What are the 4 slave systems of WMM?
Central executive
Phonological loop
Visuo-spatial sketchpad
Episodic buffer
What is the role of the central executive?
Determines how resources are allocated
Reasoning/decision making
In control
What is the role of the phonological loop?
Deals with auditory information
What are the 2 parts of the phonological loop?
Phonological store Articulatory system (maintenance rehearsal)
What is the role of the visuo-spatial sketchpad?
Stores visual information
What are the 2 parts of the visuo-spatial sketchpad?
Visuo-cache
Inner-scribe
What is the role of the episodic buffer?
General, extra storage system
Integrates information from all the other slave systems
What are the 3 types of LTM?
Episodic
Procedural
Semantic
What is episodic memory?
Personal memories of events
What is semantic memory?
Facts
What is procedural memory?
Implicit
What are 2 strengths of WMM
RS - Dual task performance –> Baddeley
Brain scan evidence for different types of LTM
What are 4 weaknesses of WMM
OP.A - MSM more emphasis on rehearsal
RL - brain-damaged patients are rare
TL - EB and CE not fully explained, vague
Difficult to distinguish between episodic and semantic LTM
Outline dual task performance
