Memory Revision

Memory Revision

1. Sensory Register

   • Duration: 1/4 - 1/2 seconds
   • Capacity: very large
   • Encoding: sense specific

2. Short-term Memory

   • Duration: 0 - 18 seconds
   • Encoding: Mainly acoustic
   • Capacity: 7±2 items

3. Long-term Memory

   • Capacity: Unlimited
   • Duration: Unlimited
   • Encoding: Mainly Semantic (can be acoustic/visual)

4. Multi-store Model A03

   • Strength: gives us good understanding of the structure and process of STM, this is good because it allows researchers to expand on this model.
     • means researchers can conduct experiments to improve the model
       • makes the model more valid
   • MSM oversimplifies STM & LTM: much more complicated
     • e.g// The Working Memory Model (Baddely & Hitch) showed that STM is not a simply unitary store and comprises of different components
       • e.g.// Central Executive, visual-spatial sketchpad etc.
   • Model suggest that rehearsal helps info to transfer to LTM, which is not essential. it raises questions like; how are we able to recall info which we did not rehearse (e.g/ swimming) but unable to recall info which we did rehearse (e.g// revision notes)
     • Therefore, importance of rehearsal is not as significant as Atkinson & Shiffrin

5. Research study for STM & LTM (AO1 & A03)

   • Glanzer & Cuntiz show that when participants were presented with a list of words. They tend to remember the first few and last few.
     • Serial Dispostion Effect
       • Supports existence of separate LTM & STM stores because they observed a primacy and recency effect
   • Case of KF also supports distinction between STM & LTN
     • KF had been in a motorcycle accident where he sustained brain damage
     • His LTM seemed to be unaffected but only able to recall last buts of info in his STM
