  Bahrick et al.

  Recall names of high school class after different amounts of time in two conditions - free recall/photo recall

  15 years: Free recall = 60% / Photo recall = 90%

  45 years: Free recall = 30% / Photo recall = 70%

  Strength - external validity / Weakness - reliability
• What is the capacity of ltm?

  Unknown

  • impossible to research
  • believed to be limitless
