Working memory model

Working memory model

1. CENTRAL EXECUTIVE - responsible for organising memories and allocates them to other slave systems

   • Retrieves info from LTM or from 5 senses and assigns to loop or VSSP for processing. It has non-specific modality

2. PHONOLOGICAL LOOP

   • ARTICULATORY LOOP- voices info that you are rehearsing and holds onto memory of sounds
     • Subvocalising- talking to yourself.
   • PHONOLOGICAL STORE- acts as inner ear
     • Holds information in speech form

3. VISUAL SPATIAL SKETCHPAD -inner eye

   • Handling visual and spatial info. Stores info on how things look and allows us to recreate images.

4. EPISODIC BUFFER- back up store

   • Linking and storing info.
   • Binds and weaves memories into single episodes.

5. CREDIBILITY

   • Backed up with brain scans showing visual and acoustic encoding in diff parts of the brain
   • Face validity- matches up with what we feel when we remember things
   • dual task paradigm- individual performing two tasks at the same time. WMM explains this
   • KF case study- brain damage from motorbike accident (STM affected). His verbal info affected but visual not affected. This shows visual is seperate in processing from verbal info.

6. CONTRADICTING ( DIFFERENCES) Multi store model focuses on sensory, stm and ltm and the encoding, duration and capacity. Whereas WWM focuses on a more complex idea of STM.

7. APPLICATION TO REAL LIFE- how to improve our memory in some situations. Suggests you can concentrate on 2 different coded sources at the same time. It can help people with dementia.
