3.9 based on 9 ratings

Materials:

  • 25 volunteers, 5 four to seven-year-olds, 5 twelve to fifteen year-olds, 5 twenty-year-olds, 5 forty-year-olds, and 5 sixty-year-olds
  • computer and printer to make number cards
  • 6 index cards
  • Scissors
  • Glue stick
  • Marker
  • Paper
  • Pencil
  • Stopwatch or timer

Procedure

  1. Gather the necessary materials. Decide on the volunteers. You will test each volunteer separately.
  2. On the computers using the Times 36 font and size, make the following letter sequences: Z T A D L O W C L P K X J T B R Q S E R X M B R V Y N F C Q Z T X I V E A W M P F J
  3. Cut the letter sequences apart and glue each one on a different index card.
  4. Provide each volunteer with a piece of paper and a pencil. Have them write their age at the top of the paper. One at a time, test each subject’s memory by showing them one index card for 5 seconds, then ask them to write the letters they saw in order on a piece of paper. Repeat with the other 5 cards.
  5. Figure out the percentage of correct responses each volunteer provided. To find the percentage, divide the number of letters possible (42) by the number of letters they correctly remembered. Record the information.
  6. Analyze the data and draw a conclusion.
