STM Duration

• Who investigated the duration of short-term memory?

  Peterson and Peterson
• What method did Peterson and Peterson use to test memory duration?

  Participants counted back in 3's from 300
• What were the time intervals used in the study?

  3, 6, 9, 12, 15, or 18 seconds
• How did counting back affect participants' memory?

  It broke their ability to use maintenance rehearsal
• What did Peterson and Peterson conclude about short-term memory duration?

  It lasts 18-30 seconds
• What is one strength of the research into duration?

  It used highly controlled lab conditions
• What did all participants do during the experiment?

  Counted back aloud for the same time intervals
• Why is the research considered valid for the multi-store model of memory?

  It shows short-term memory has a different duration
• What is a limitation of the study regarding ecological validity?

  Findings are hard to apply in real life
• Why were trigrams used in the study?

  They were purposefully meaningless
• What could have improved the memory recall in participants?

  Using meaningful 3-letter words
• What does the study not account for regarding memory recall?

  Why we remember important information without rehearsal
• What is an example of a memory that might imprint into long-term memory?

  A flashbulb memory from a crime
• What is a limitation of the research regarding emotional connections?

  It only explains simplistic information without emotion
• What type of memory does the study focus on?

  Short-term memory
• What is the significance of the study's findings for memory models?

  It supports the multi-store model of memory
