Ask your friend to write down a list of 15 common objects and then number them from 1-15 in the order they will be read to you. It would be helpful if all of them have relatively short, 1- or 2-syllable names. Your friend should read to you the list of 15 words in a monotone voice at the rate of 1 word approximately every 4 seconds.

Describe the typical serial position curve and explain, according to the Atkinson and Shiffrin model, why it is shaped as it is.

Explain what the Atkinson and Shiffrin model would predict about:

• The three scores you calculated
• The order in which you wrote down the words on your answer sheet.
• Discuss whether your data (your three scores) fit the predictions of the model. If not, then discuss some possible reasons why not.
