Working memory model

Who was the working memory model developed by?

Baddeley and Hitch (1974)

How does the Working Memory Model differ from the Multi-Store Model?

• The STM is no longer passive instead it is an active ‘working’ part of the memory

• STM doesnt just code scoustucally

• STM isnt a unitary store but is made up of many parts, each with a specalist intent

Think of the Working Memory Model diagram (cause i cant type it so it will be a picture)

:)

Name the different parts of the Working Memory Model and their subparts

• Central executive

• Phonological loop (articulartory control system and phonological store)

• Eposodic buffer

• Visuo-spatial sketchpad

• Long term knowledge (Language, Episodic LTM, Visual semantics)

What is the central executive:

• It controls attension, filters stimuli and coordinates the actions of other slave systems

• It can breifly store information

• It has limited capacity

• It is modality free

What is the phonological

Contains two subsystems:

• Articulatory control system:

• rehearses inforamation subvocally

• Duration of 2 seconds

• System we use to mentally rehearse

• Phonological store:

• Uses a sound based code

• Duration of 2 seconds (unless rehearsed by ACS)

Visuo-spetial sketchpad

• Stores and manipulates visual information

• subdivided → visual cache ( store visual information)

Inner scribe ( records the arrangement of objects in the visual field)

What is the episodic buffer

• Intergrates all other inforamtion from other subsystems into one starnd and a single memory

• Provides a bridge between working memory and LTM

• Tempory store

• Limited capacity

• Time stamps memories
