1. TYPES OF MEMORY

   • Sensory
     • Where stimuli first registers in the memory system and only stays there for a fraction of a second
     • Sperling- Did the 3 rows of letters to remember an recall
   • Short term
     • Damage in temporal lobe leads to STM deficit
   • Long term
     • Damage in hippocampus leads to LTM deficit

2. AMNESIA

   • The temporary or permanent loss of memory
   • Reterograde= LTM deficit but STM preserved
     • Korsakoffs syndrome
   • Anterograde= LTM preserved but STM defecit
     • Patient KF

3. LIMITATIONS TO STM

   • Capacity
     • Miller- 7 plus or minus 2
   • Duration
     • Petersons- recall words after counting backwards in 3s
   • Encoding
     • Conrad- found that STM encoding is acoustic

4. DISTRACTIONS

   • Glanzer & Cunitz
     • Asked 200 army men to remember words with and without a distraction
   • With= primacy effect but no recency

5. MULTI STORE MEMORY MODEL

   • Sensory memory
     • Short term memory
       • Long term memory
       • Rehearsal
     • Attention
   • Negatives
     • Simplistic
     • Doesnt work with reterograde memory
     • Traumatic experiences dont need rehearsing to stay in long term memory
