Cognitive

1. Multi-store model of memory

   • Coding - form the info is stored in
   • Capacity - how much info can be stored
   • Duration - how long info can be stored for
   • Haptic
   • Iconic
   • Echoic
   • Gustatory
   • Olfactory

2. Sensory Register

   • Coding
     • Many stores
     • Crowder: info: iconic - few milliseconds, echoic - 2-3 seconds. Sensory memory coded into different sensory stores
       • Study lacks ecological validity
   • Capacity
     • Large & contains unprocessed highly detailed ever-changing info
     • Sperling: capacity of SR is quite large
       • Study lacks ecological validity
   • Duration
     • All have limited duration: different amounts, decreases with age
     • Treisman: echoic store - 2 seconds, iconic store - 0.5 seconds (Walsh & Thompson)
       • Study lacks ecological validity

3. Short Term Memory

   • Coding
     • Info from SR encoded in a form that STM can easily deal with, main form of coding is acoustic
     • Baddeley: STM coded on an acoustic basis
   • Capacity
   • Duration
