Multi-store model of memory

Multi-store model of memory

1. Sensory input

   • Sensory register
     • Decay if attention isn't payed
     • Attention
       • Short term memory
         • Rehersal
         • Decay if attention isn't payed
         • Encode
           • Long term memory
             • Information lost over time
             • Encoding
               • Semantic
             • Duration
               • Doesn't expire
             • Capacity
               • Unlimited
         • Retrieval
         • Encoding
           • Acoustic
         • Duration
           • 30 seconds
         • Capacity
           • 7 + or - 2 chunks of information
     • Encoding
       • 5 senses
     • Duration
       • Few milliseconds
     • Capacity
       • Very Limited

2. Case Study

   • HM
     • Surgery to remove hippocampus
     • Cannot make new conscious memories
     • Retrograde memory loss
     • Retained ability to learn new motor skills
