peterson and peterson short term retention

    Cards (14)

    • What was the aim of the study on short-term memory?
      To test the true duration of short-term memory
    • How many students were tested in the short-term memory study?
      24 students
    • What task were participants asked to perform after recalling a trigram?
      Count backwards from a 3-digit number
    • How might the lack of control in Bartlett's procedures affect the study's findings?
      It could lead to variability in results and affect reliability.
    • What were the time delays used for recalling the trigram?
      3, 6, 9, 12, 15, and 18 seconds
    • How many times was the experiment repeated with different trigrams?
      48 times
    • What was the effect of longer counting times on trigram recall accuracy?
      The accuracy decreased as counting time increased
    • What percentage of trigrams were recalled correctly after 3 seconds?
      Over 80%
    • What percentage of trigrams could be recalled after 18 seconds?
      Less than 10%
    • What was the purpose of the second experiment?
      To give participants time to repeat the trigram before counting back
    • What was the outcome of the second experiment regarding recall frequency?
      Extra time increased recall frequency but showed a similar decline
    • What are the main conclusions of the study on short-term memory?
      • Information in short-term memory fades rapidly
      • Only 10% could be recalled after 18 seconds
    • What are the strengths of the short-term memory study?
      • Standardised procedures
      • Scientific reliability (can be replicated)
      • Practical application to daily life
    • What are the weaknesses of the short-term memory study?
      • Lacks mundane realism (nonsense trigrams)
      • Limited generalisability (focus on students)
