• What is a limitation of Peterson and Peterson's study?

  The stimulus was artificial
• Why is the study still somewhat relevant?

  Sometimes we do try to remember fairly meaningless material (phone numbers)
• Recalling consonant syllables does not reflect most everyday memory activities where what we are trying to remember is meaningful
• What does this study lack?

  External validity
• What is a strength of Bahrick's study?

  It has high external validity
• What type of memories did he investigate?

  Meaningful memories i.e names and faces
• What did Shepards say about studies on LTM?

  When they're conducted with meaningless pictures, recall rates were lower
• What does this suggest about Bharick's study?

  Its findings reflect a more 'real' estimate of duration of LTM
