1. LTM

   • Bahrick et al- Duration
     • Photo, name, free recall+ combination
     • up to 50 years afterwards
       • 70% accurate in photo recognition
       • free recall was less accurate

2. STM

   • KF
     • more than one type
       • is too simplistic
   • Miller- Capacity
     • 7+- 2

     • Triagrams+ 3 digit numbers, counting backwards
     • 18-30 seconds

   • coding
     • STM- Acoustic
     • LTM- Semantic

4. Sensory Register

   • Echoic- hear
   • Iconic- see

5. Recall Rehearse

   • elaborative rehearsal
   • maintenance

6. Research evidence

   • lots of it support model
   • good internal validity
   • low external validity
     • artificial tasks
     • cannot generalise
