Duration evaluation

• STM LIMITATION

  • Peterson and Peterson's study used artificial stimuli; the study contained lists of words that were not ecologically valid
  • as they were not normal items, we have to remember, meaning they are not relevant to everyday life
  • lacks real-life application
• LTM STRENGTH

  • Bahrick used meaningful materials such as pictures
  • memories are more meaningful and representative of things we would try to recall in our day
  • results in higher external validity
  • applicable to scenarios outside the research context
• STM AND LTM LIMITATION

  • study is outdated
  • referred to as a child of its time
  • research is old, so it may not apply to modern day
  • lacking temporal validity
