Models of memory

Models of memory

1. Multi-store model

   • Evidence FOR
     • Sensory register (Sperling)
       • participants saw numbers and letters for 50 milliseconds and the found it hard to recall all information as could not pay attention
         • shows that information int he sensory register decays quickly
     • Serial position effect (Glanzer and Cunitz)
       • remember words at start and end of a list, middle words are forgotten
         • Primacy effect - rehearsal so are staying in STM and transferring into LTM
         • Recency effect - still in STM when list is being recalled
     • Case study of HM
       • had brain damage after a operation to reduce bis severe epilepsy
       • could not form new long term memories but his STM was not damaged
         • shows STM and LTM are different stores
   • Evidence AGAINST
     • Case study of KF
       • suffered brain damage from a motorbike accident that damaged his STM, only verbal info was affected but visual memory was fine
         • suggests there is more than one type of STM, the MSM treats all STM the same when there may be more than one store for STM
           • an oversimplication of memory
     • Rehearsal doesnt ensure the transfer of info from short to long term
       • when the BBC changed the wavelengths listeners were reminded several times but most claim they didnt hear about the changed
     • some things are more easily remebered than others and the MSM doesnt explain this
