1. Introduction

   • distinctions LTM and STM Baddeley 1986
   • memory as a multifaceted system
     • Hitch 1978 wm keeps track of transient info errors due to forgetting
   • Distinctions between STM and LTM
     • Baddeley 1966 showed that immediate recall was poor for phonelogically similar items but there was nl effect for semsntically simliar items
       • 2 sub systems LTM = semtantic STM = Phonetic
     • Brown 1956 Rate of forgetting briefly presented stimuli, rapid according to rates of other learned material, STM more liable
     • Miller 1958 memory span limited to just a few items, suggests distinction of stm by limited capacity
     • Actkinson and shiffrin 1971 eg of modal model
     • Murdock 1967 modal model
       • stm= limited capicity store control process = subvocal rehersal used to maintain, info in stm gradually moves to ltm
