Working Memory Model

Baddeley and Hitch (1974)

• Argued STM more complex than just 'stopping off station' for info to transfer to LTM
• Proposed STM should be replaced by working memory
• WM allows several pieces of info to be processed and interrelated simultaneously and info can flow LTM to STM as well as the other way round
• 'Working' because it's an 'active store that holds info which is being manipulated and woken upon

Central executive allocates resources dependent on cognititve demands and controls other component systems

The phonological/articulatory loop is a temporary acoustic storage system for verbal info that is used to repeat info (e.g phone numbers) or store words before they're spoken.

• Articulatory control process holds words for sub-vocal repetition to prevent decay, also known as the 'inner voice'
• Phonological store represents auditory info in terms of pitch and volume, also known as the 'inner ear'

Visual spatial sketch pad rehearses visual/spatial info.

Logi (1995)

• Visual cache stores visual info, e.g. form and colour
• Inner scribe stores info about spatial relationships
