  • MEMORY REVISION PSYA1
    • STM
      • something that happend in the present or immediate past
        • Duration - upto 30s
          • Peterson & Peterson
            • 24 participant onesense trigram count back in 3's retention interval increased recall decrease
        • Capacity - 7+-2
          • Jacobs
            • Digit span, letters and numbers increased length of list until p's recalled incorrectly
        • Encoding acoustic visual
          • Baddely
            • Created audio confusion 4 lists of words, immediate recall, did worst recalling acoustically similar list
              • Low in ecological validity , support that there is some semantic encoding and some visual encoding
              • Untitled
            • Baddely
              • same as  STM but left a 20min gap before recall, struggled with semantically similar
    • LTM
      • things that happened in the distant past
        • Capacity - potentially limitless
        • Duration - potentially limitless
          • Bahrick et al
            • Show participants pictures of school friends from 40 years after they left
              • recalled 80% of names
              • , wasnt contrlled , tested visual side of LTM
        • Encoding semantic acoustic visual
          • Baddely
            • same as  STM but left a 20min gap before recall, struggled with semantically similar
    • MSM Atkinson & Shiffin
      • distinct types of memory
      • Serial position can recall start and end of a list (LTM & STM)
        • AKA Primary recency effect
      • Rehersal may not be enough to fix info in LTM
      • Oversimplistic, WMM shows different types of STM
    • WMW Baddely & Hitch
      • Deals with STM and recently activated LTM
      • Passive stores through which info flows
      • Cental Executive
        • Phonological loop
          • Articulatory loop & Phonological store
            • inner ear
            • inner voice
          • holds speech based info and audio info
        • Visuo spatial scratchpad
          • Visual and spatial info, size colour shape
        • Episodic buffer was added later to deal with 'other stuff'
    • EWT
      • Anxiety
        • Weapon focus
      • Age
        • Small et al carried out longtiduinal study of 2 healthy groups of adults. 60-60 , and 70+.relative decline with age particularly with acquistition of new material.
      • recconstruction which can suffer damage at any stage
        • we will fill in missing gaps SCHEMA
      • Cognitive interviews
        • leading questions
          • loftus and palmer
            • 45 students shown films of car accidents. questionnaire , crucial question varying verb use , crashed or smash bumped or hit or collided
              • results showed smash gave highest estimate and contacted gave lowest
              • SECOND EXPERIMENT. 150 PP. 3 CONDITIONS SMASHED HIT CONTROL GROUP.WEEK LATER 10 QUESTIONS ASKING IF THEY SAW ANY BROKEN GLASS. SMASHED - CONDITION HIGHER SPPED AND SMASHED GLASS
          • Yuille and Cutshall
            • interviewed 13 people who witnessed real life robbery. interviews 4 months later , 2 misleading questions. but witnesses still provided accurate recall
  • 45 students shown films of car accidents. questionnaire , crucial question varying verb use , crashed or smash bumped or hit or collided
    • results showed smash gave highest estimate and contacted gave lowest
    • SECOND EXPERIMENT. 150 PP. 3 CONDITIONS SMASHED HIT CONTROL GROUP.WEEK LATER 10 QUESTIONS ASKING IF THEY SAW ANY BROKEN GLASS. SMASHED - CONDITION HIGHER SPPED AND SMASHED GLASS
