Multi-store Model

Multi-store Model

1. Model itself

   • Sensory register (all senses, iconic, echoic)
     • Short-term memory
       • Long-term memory
         • Prolonged Rehearsal
       • Retrieval
       • Attention

2. Sensory Register

   • All stimuli from environment enter
   • Coding depends on the sense so is modality-specific
     • Iconic for visual, echoic for acoustic
   • Duration is less than half a second
   • Capacity is very high as it absorbs so much information
   • Attention passes the information to the short-term memory

3. Short-term Memory

   • Coding is acoustic (hearing)
   • The duration is around 18 seconds long
   • The capacity is 'Miller's Magic Number 7+-2'
   • Prolonged rehearsal passes the information to the long-term memory

4. Long-term Memory

   • Coded is semantic (which is meanings)
   • Duration and capacity is potentially permanent as people remember things for their lifetime
     • Bahrick's memory study with year books
   • We do retrieval to bring it back into our short-term memory
