memory 3 Flashcards
how did Ebbinghaus investigate LTM?
did memory testing on himself
used the method of savings- having learnt a list once sees how much faster he can learn it a second time
how are forgetting functions best described?
as a power function
reduces over time but is never completely degraded
how did Bahrick investigate long term memory? (Spanish)
tested people’s memory for Spanish taught in schools up to 50 years ago
performance was closely related to initial learning even 50 years later
decayed rapidly but then levelled off
still above chance despite no use/rehersal of Spanish
how did Standing test the capacity of the LTS?
participants watched slides for 5 seconds each
then had a recognition test 2 days later
even with 10,000 items learned, performance was still 83% correct
why is it suggested that visual search has no memory?
search slope was unchanged even when stimuli randomly interchanged
don’t remember where we just looked
what do we store of images?
the gist rather than the fine details
how did Bahrick investigate LTM? (forgetting faces)
tested the ability of college teachers to recognise and identify previous students
8 years later could still recognise, but not identify
how did Young, Hay and Ellis research forgetting faces?
participants kept a diary, and noted down errors they made in face recognition and identification
made an average of 6 errors a day
errors included failing to recognise someone, mistakenly identifying someone, forgetting a person’s name etc
what is verbal overshadowing of memory?
wanted to see if you can improve face memory by carefully describing faces you see
giving a verbal description of a face actually impaired subsequent memory for the face in a recognition test
what happened in the misremembrance of wines?
value of verbailisation can depend on expertise
novice wine drinkers have their memories enhanced
expert wine drinkers are unaffected
intermediate wine drinkers have their memory removed
