memory models

1. multi-store model

   • sensory regiter
     • forget by decay or displacement
     • ionic memory visual information
     • echoic memory auditory information
     • haptic memory tactile information
   • short term memory
     • forgetting by decay or interferance
   • long term memory
     • forgetting by decay
   • by giving the memory attention the memory can pass from one store to the next
   • the serial position curve shows that middle items are the hardest to remember because they don't make it to the long or short term memory

2. working memory model

   • central executive
     • controls two slave systems
     • limited capacity
     • controls decision making
   • phonological loop
     • processes verbal inforation
     • limited capacity
     • articulatory control system
       • the inner voice
     • phonological store
       • the inner ear
   • visuo-spatial sketchpad
     • processes visual information
     • limited capacity
     • visual cache
       • visual images
     • inner scribe
       • movement information
   • episodic buffer
     • short term memory store
   • long term memory
