MSM

1. Environmental stimuli

   • SM
     • Attention
       • STM
         • Elaborative rehearsal
           • LTM
             • Retrieval
             • Unlimited capacity
               • Semantic encoding
                 • The more something is rehearsed, the more lasting the memory will be
                   • Lifetime duration
         • Maintenance retrieval
           • Verbal
         • Information retrieval
         • Memory will decay if not rehearsed
           • New info. can push out original info. due to limited capacity (displacement)
             • Acoustic encoding
               • 30 seconds duration
             • 7 +/- 2 chunks
     • Eyes, ears, etc. and corresponding areas of brain
       • Very limited capacity so attention can't be paid to everything
         • 2 seconds duration
   • 5 senses

2. The 3 stores are independent but associated through processes

3. Strengths

   • Glancer + Cunitz
     • Primacy and Recency effect
       • Proof for STM and LTM
         • Show link between them (rehearsal)
   • HM - couldn't form new long term memories
     • shows there is a 'gateway' between STM and LTM
       • linked through processes - however other processes should be considered (over simplification)

4. Weaknesses

   • Suggests STM and LTM are unitary stores
     • KF - issues in dealing with verbal information in STM but normal ability in processing visual info.
       • therefore STM not a single store as MSM suggests
   • Over simplifies memory/the stores
     • An alternative more detailed/complicated model could be better in explaining memory
       • MSM less accurate and therefore less useful
