Memory

Memory

1. levels of processing

   • describes two types of precessing
     • shallow and deep
   • deep processing
     • leads to better recall
     • gives information meaning
   • shallow preocessing
     • physical features
       • a word

2. memory aids

   • cues
     • helps to trigger and access lost information
       • through senses
     • different perfume for every subject revised
       • same perfume for exam
         • cue to remember revision

3. multistore model

   • separate and distinct stores
     • sensory, stm and ltm
     • time and space
   • sensory store
     • immediate surroundings
     • few seconds
   • STM
     • paid attention to
       • if not it will decay
         • not used in capacity
     • 10- 20 seconds
     • 7 +/- 2 chunks
       • exceeded = displcement
         • shunted out by new info
   • LTM
     • maintenance rehearsal
       • 30 seconds
     • unlimited capacity and duration
   • criticisms
     • over simplifies the LTM and STM
     • over emphasizes role of rehearsal
     • ignores individual differences

4. terry

   • aim
     • affected by time and space & test serial position effect
   • procedure
     • repeated measures design
     • 39
     • 15 blocks, 30 seconds. 10 months
     • IV: when recalled
     • DV: how many brand names recalled
   • results
     • serial position effect
     • immediate
       • primacy and recency
     • delayed
       • recency lost
   • conclusion
     • first
       • rehearsed
     • last
       • still in STM - not yet decayed
     • middle
       • displaced or no rehearsal
     • task = decay and displacement
   • criticisms
     • lab = lack ecological avlidity
     • lack construct validity
     • demand characteristics
