LT1 - Multi-store Model of Memory

LT1 - Multi-store Model of Memory

1. AO1

   • SR, STM, LTM
     • Separate Stores
     • Different Locations
     • They function individually
     • Sensory Register
       • Encoding
         • The format in which coding memories are stored
         • Echoic Store
           • Iconic Store
             • Visual information proceesed visually
           • Auditory Info proceessed Acoustically
       • Vast capacity
         • Processing millions of pieces of electrical info at any time
       • <0.5 Duration
       • For info to pass to STM?
         • We need attention
     • STM
       • What we're currently focused on
       • Capacitty?
         • Encoding?
           • Duration?
             • 18-30 Sec (peterson and peterson)
           • Acoustic (baddeley)
         • 7+-2 (Miller)
           • 9.3/7.3 (Jacobs)
       • Maintainence Rehearsal
         • Acoustic Repetition
           • Of STM info
             • To retain longer than duration
     • LTM
       • Encoding?
         • Semantic (Baddeley)
       • Capacity?
         • Potentially Unlimited
       • Duration?
         • Potentially Limitless
       • Elaborative Rehearsal
         • Prolonged Acoustic Repetition
           • of STM info
             • Transfers it to LTM
       • Retrieval
         • Recalling LTMs
           • Temporarily in STM
             • As long as attention/focus on it
               • Decay when no longer needed, return to LTM

2. AO3

   • Strengths
     • P: Supporting Evidence
       • E1: HM - HC removed Vs Epilepsy, Amensiac, no new LTMs, normal STM, only remembers before 16
         • L: Supports claim of separate stores
   • Weaknesses
     • P: Oversimplified types of rehersal
       • E1: Craik, Watkins - TYPE of rehearsal matters. Store alongside pre-existing
         • L: Type matters, not comprehensive
     • P: Oversimplified STM
       • E1: Shallice & Warrington
         • E2: KF - Impaired Audio STM, Unimpaired Visual STM
           • L: Challenges A&S claim that STM is a single unit, not global
