1. Models

   • Multi Store Model Atkinson and Shiffrin
     • Model
       • Sensory - Short Term - Long Term                             - Rehearsal - 
     • Storage
       • Sensory
         • Iconic - Visual part, for example you remember what you see, lasts around 0.5 seconds Echoic - Acoustic part, you can remember what you hear, lasts a few seconds
       • Short Term
         • Encoding - Conrad 1964, people mixed up letters that sounded acoustically similar Capacity - Miller 1956, people could remember lists of 7 +/- 2 items, also increase if chunking method was used Duration - Peterson and Peterson 1959 Trigrams fade after around 18 seconds
       • Long Term
         • Encoding - Semantic Capacity - Potentially unlimited Duration - Potentially a lifetime -Bahrick Et Al -Ques
     • A02
       • Strong - seems to be a difference in the systems for example clive wearling ltm worked but stm was damaged Strong - Can explain primary and recency effects Weak - Does not display the three tyoes of LTM episodic procedural and semantic
   • Working Memory Model Baddely and Hitch
     • Model
       • The Central Executive |                        | |          Viseo Spatial Sketchpad The phonological loop
     • What is it?
       • Viseo Spatial Sketchpad
         • The 'inner eye' organises all information visually as you would as if you were sketching them out on paper. Its the mental 'rough paper' you might use when doing arithmatic
       • Phonological Loop
         • An Auditory store, rehearses information in two separate ways.  Phonological store - considered the inner ear, deals with the perception of sounds and speech Articulatpry Loop - the inner voice Baddely 1986 said it rehearses sounds for 2 seconds
       • Central Executive
         • Manages the system, the other components are slave systems and do exactly as the central executive decides they should do.
