Evaluation of multi-store model

Evaluation of multi-store model

1. Support from case studies

   • CASE OF HM
     • Suggests that stores of memory are separate.
     • Had brain surgery to relieve epilepsy - hippocampus removed (central to memory function)
       • Could no longer form LTM
       • Remembered things before his surgery
       • STM was not damaged
   • Sperling's sensory memory test
     • Showed participants 3 rows of numbers and letters followed by a high, middle, or low tone. (Tone = indication of what they needed to remember.
       • High = top row Middle = middle row Low = bottom row
       • Most participants were able to recall the whole row that was sounded for them
     • The tone was sending the info to the STM - supports idea of sensory register.

2. A weakness is that its too simplistic.

   • Doesn't allow for different types of LTM & STM

3. Clive Waring = supports the weakness that it doesn't allow for different types of LTM & STM

   • Lost his memory due to infection of the brain & was left with a 7 second STM
     • Couldn't form long term memories; he would forget everything he learnt after 7 seconds.
       • He was able to recognise his wife but acted as if he hadn't seen her for years.
       • When asked if he could play the piano, he would say no however if he was sat infant of a piano he would play very well.
         • Suggests that there are different types of STM
