General

retrieval practice of material to-be-remebered during learning improves learning success (and more than subjectively expected)

  • retrieval effort hypothesis
    • when retrieving memory there is a deeper trace than when just reading
    • the harder it is to retrieve the longer it will stay in memory
      • the pathway is strengthened more then
  • can be used regardless of the material
    • reproduction > rehearsing

Empirical

  • Roediger & Karpicke (2006)

    • n = 120
    • repeated study (4x)
    • simple recall (3x read, 1x recall)
    • multiple recall (1x read, 3x recall)
    • 5min after reading the 4x reading group was best
    • 1 week after reading the mulitple recall group was best
      • 50% better than repeated
      • recalling = long-term memory
  • Giebl et al. (2021) - answer first or google first

    • n = 240
    • no-pretest group: immediately access to external information
    • pretest group: access to external information only later
      • significantly better performance, especially for people with some experience
    • asking the questions first primes the brain to take in the info
      • finding the correct questions to ask
      • forces brain to identify the missing information, incorporated easier when supplied
