the multi-store model of memory

Cards (40)

  • what does the msm assume?
    there are separate and distinct stores for memory, each linked together but with their own capacity and duration.
  • what is capacity?

    a measure of how much can be held in memory
  • what is capacity represented in?
    bits of information, such as number of digits
  • what is duration?

    a measure of how long a memory lasts before it is no longer available
  • what is coding?
    the way information is changed so that it can be stored in memory
  • what are the 3 types of coding?

    visual, acoustic and semantic
  • what is short-term memory?
    your memory for events in the present or immediate past
  • what is long-term memory?
    your memory for things that have happened in the more distant past
  • what is environmental stimuli?
    all information we process every day but have no recollection of
  • whats the capacity of the sensory register?
    very large/unlimited
  • whats the duration of the sensory register?
    less than 1 second
  • whats the encoding type of the sensory register?
    sense specific
  • whats the capacity of the stm?
    7±2 items
  • whats the duration of the stm?
    18-30 seconds
  • how is the stm encoded?
    acoustically
  • whats the capacity of the ltm?
    unlimited
  • whats the duration of the ltm?
    up to a lifetime
  • how is the ltm encoded?
    semantically
  • what is the first step in remembering something?
    paying attention
  • what may sensory memory for visual stimuli be called?
    iconic memory
  • what may sensory memory for aural stimuli be called?
    echoic memory
  • what may sensory memory for touch be called?
    haptic memory
  • what is filtering?
    environmental information that we consider irrelevant is filtered out by a bottleneck filter and forgotten
  • what happened in H.M.?
    a patient had his hippocampus removed and he lost the ability to form new long-term memories
  • who claimed that the capacity of the short term memory was 7±2?
    george miller
  • who coined the ‘serial position effect?
    murdock
  • what is the primacy effect?
    words at the start of the list have been processed through stm and are in ltm
  • what is the recency effect?

    words are still in stm and so are easily accessible
  • what is the serial position effect?
    The tendency to remember items at the beginning and end of a list better than those in the middle.
  • what area of the brain is associated with the stm?
    pre-frontal cortex
  • what area of the brain is associated with ltm?
    hippocampus
  • who investigated the duration of stm?
    margaret and lloyd peterson
  • what did peterson and peterson find?
    short term memory has a duration between 18 and 30 seconds
  • who investigated the duration of ltm?
    bahrick et al
  • what did bahrick et al find?
    90% accuracy for face and name recall after 34 years. 80% accuracy for name recognition after 48 years. 40% accuracy for face recognition after 48 years. 60% accuracy for free recall after 15 years. 30% accuracy for free recall after 30 years
  • what is the support for the msm?
    the serial position effect or location of brain associated with stm and ltm
  • what is the counter for the msm?
    data from lab study - ecological validity/mundane realism
  • what is the alternative for the msm?
    working model of memory
  • what is the practical application for the msm?

    improve recall ability
  • what are the issues and debates of the msm?
    uses both idiographic and nomothetic methods to provide support for the mode
