The working memory model

• The working memory model (WMM) is an explanation of how one aspect of memory (short-term memory) is organised and how it functions
• Working memory model (WMM) - A representation of short-term memory

  • It suggests that STM is a dynamic processor of different types of information using subunits co-ordinated by a central decision-making system
• Working memory model:

  Baddeley & Hitch (1974) claimed that dual-task performance suggests that STM has more parts than being just one store

  • They proposed the Working Memory Model
  • The model suggests that the STM is an ‘active’ store, holding several pieces of information why they were being worked on (hence ‘working’ memory)
• The WMM consists of 4 main components:

  • Central executive
  • Phonological loop
  • Visuo-spatial sketchpad
  • Episodic buffer
• WMM Slave systems:

  1. Phonological loop
  2. Visuo-spatial sketchpad
  3. Episodic buffer
