Working memory model

Working memory model

1. 1. central executive

   • Monitors incoming data, makes decisions & allocates slave systems to tasks
   • Limited storage capacity

2. 2. Phonological Loop

   • Deals with auditory info & preserves he order in which the info arrives
   • Phonological store = stores the words you hear
   • Articulatory process = which allows maintenance rehearsal (repeating sounds or words in a loop to keep them in the working memory where they are needed)
   • Capacity = 2 seconds worth of what you can say

3. 3. Visuo-spatial sketchpad.

   • Stores visual/spatial info when required.
     • E.g. if you are asked how many windows your house has you will visualise it.
   • Limited capacity = 3/4 items.
   • Visual cache = stores visual data Inner scribe = records the arrangement of objects in the visual field

4. 4. Episodic buffer

   • Added to the model by Baddeley in 2000.
   • Temporary store for info - integrating the visual, spatial and verbal information processed by other sources
   • Maintaining a sense of time sequencing - basically recording events that are happening.
   • Storage component of the central executive. Has a limited capacity of about 4 chunks.
   • Links working memory to LYM & wider cognitive processes such as perception
