Q

Serial position effect (evidence for separate memory stores) (3)

  • primacy and recency effects
  • proactive interference > < retroactive interference

Q

Evidence for separate memory store (2)

A
  • rapid presentation of list disrupts primacy effect, whereas delayed recall of list disrupts recency effect
  • neuroimaging studies: hippocampus vs sensory info areas and brain damage differentially affects STM and LTM
