coding, capacity and duration of memory

• What is acoustic


  Relating to sound or the sense of hearing.
• What is semantic


  Relating to the meaning of words or language.
• What does limitation mean in a study

  Constraints or shortcomings in a study that affect its validity or generalizability.
• What does capacity mean

  The maximum amount of information that can be held or processed by a system.
• What is a digit Span


  The number of digits a person can remember in a specific order.
• Chunking


  Grouping sets of information into larger units or chunks.
• What is External Validity

  The extent to which the results of a study can be generalized to real-world settings.
• PARTICIPANTS WERE SHOWN ORIGINAL WORDS AND THEN ASKED TO RECALL IN THE CORRECT ORDER WHAT WAS THE RESULT OF 'STM RECALL' ?

  they did worse on acoustically similar words
• PARTICIPANTS WERE SHOWN ORIGINAL WORDS AND THEN ASKED TO RECALL IN THE CORRECT ORDER AFTER 20MINS WHAT WAS THE RESULT OF 'LTM RECALL' ?

  they did worse on semantically similar words suggesting that information is coded semantically in LTM
• RESEARCH ON CAPACITY BY JACOBS

  Includes studies on digit span, span of memory, and chunking.
• WHAT IS THE DIGIT SPAN

  A technique developed by Joseph Jacobs to measure the number of digits a person can recall.
• HOW DOES DIGIT SPAN WORK?

  participants are given 4 digits to recall, if they can then the number of digits increases

  mean- 9.3 for digits

  mean- 7.3 for letters
• WHAT WAS THE SUGGESTED SPAN OF MEMORY BY MILLER

  George Miller suggested the capacity of the STM is 7 items (+/- 2) which also worked with letters

  observed that things come in 7s (7 deadly sins, 7days of the week)
• WHAT IS CHUNKING


  grouping sets of digits/letters into units/chunks
