Memory experiments and theories Flashcards
Atikson and shiffrins multi store model of memory
sensory –>attention
= STM (maintain rehersal) —> encoding rehersal
Short term memory (STM)
capacity= 5-9 duration= 18 sec encoding= acoustically forgetting= decay or displace
Long term memory (LTM)
capacity= limitless duration= semantically encoding= semantically forgetting= decay or retrival failure
Peterson and peterson
lab experiment
test the duration of STM
students would repeat a trigram and then count backwards from a number is 3s or 4s then recall the trigram
peterson and peterson conclusion
information in the STM fades rapidlyand only 10% could recall after 18 sec
Bartlett (1932) the war of the ghosts
tested the nature of reconstructive memory through telling an american old folk tale to students from Cambridge university
serial reproduction
retell a story to another participant (Chinese whisper)
repeated reproduction
asked to write down the story and recall it in several min, hours,days and years
Bartlett’s theory of reconstructive memory
memories are like notes and when we recall them we retrieve them and elaborate on them using general knowledge
proposed the idea of ‘schema’
Antagorade amnesia symptoms
difficulty in remembering and learning new things
Retrograde amnesia symptoms
loosing memories
