Memory

1. models of memory

   • multi store
     • environmental stimulus
       • sensory memory
         • short term
           • long term
             • lost through retrieval failure
           • decay
             • displacement
               • capacity limit has been reached and therefore information needs to be discarded in order to make room from new incoming information
             • the duration has been exceeded and the information fades from memory store - can be prevented by elaborate/maintenance rehearsal
           • elaborative or maintenance rehearsal
         • attention paid leads to info being sent to stm
     • evaluation
       • negatives
         • vague
         • linear
         • reductionist
       • positives
         • encouraged more research into models of memory
         • explains how stm and ltm are separate stores
       • clive wearing and hm
   • working memory
     • central executive
       • visual spatio sketchpad
         • visual and spatial information
         • inner eye
       • phonological loop
         • phonological store
         • articulatory control system
         • inner ear and inner voice
       • episodic buffer
