  • What is the title of the study material?
    Coding, Capacity, and Duration
  • What studies are included in the section on coding?
    • Baddeley: acoustically and semantically similar words
  • What did Baddeley use to test memory recall?
    Different words given to four groups
  • What types of words did Baddeley use in his study?
    Acoustically similar, dissimilar, semantically similar, dissimilar
  • What was the immediate recall finding in Baddeley's study?
    Worse with acoustically similar words
  • What was the delayed recall finding in Baddeley's study?
    Worse with semantically similar words
  • Why did Baddeley find immediate recall worse with acoustically similar words?
    Similar sounds cause confusion in recall
  • Why did Baddeley find delayed recall worse with semantically similar words?
    Similar meanings interfere with memory retrieval

    Consonant trigrams
  • What study did Bahrick conduct related to LTM duration?
    • Studied 392 American participants
    • Recall names from High School
  • What was the accuracy of recall for participants tested within 15 years of graduation?
    About 90% accurate
  • What was the recall accuracy after 48 years according to Bahrick's study?
    About 70% accurate
  • What did George Miller propose about STM capacity?
    • Span of STM is about 7 items
    • Plus or minus 2 items
  • What concept did Miller introduce to help recall items in STM?
    Chunking
  • How does chunking help in memory recall?
    It groups items into manageable units
