How Many Words Can You Remember?

A Word Memorization Experiment

In the following demonstration, look at the list of words below for two minutes. Memorize as many words as you can in this amount of time. Next, turn off your computer monitor and get out a sheet of paper. Give yourself two minutes to write down as many words from the list as you can.

Nine Swap Cell Ring Lust
Plugs Lamp Apple Table Sway
Army Bank Fire Hold Worm
Clock Horse Color Baby Sword
Desk Hold Find Bird Rock

How many words did you get correct? Despite having two minutes to memorize the words, you may find it surprisingly difficult to later recall even a handful of the words. This experiment demonstrates some of the limitations of short-term memory. According to researcher George A. Miller, the typical storage capacity for short-term memory is seven plus or minus two items. However, memory rehearsal strategies such as chunking can significantly increase memorization and recall.

For example, observe the following words:

Horse Cat Dog Fish Bird
Orange Yellow Blue Green Black
Table Chair Desk Bookcase Bed
Teacher School Student Homework Class
Apple Banana Kiwi Grape Mango

Because these items can be easily chunked based on category, you can probably remember far more of these words.

Key Terms

Before you begin your experiment, there are some key terms and concepts you should understand.

Key Questions for Background Research

  • On average, how many words can a person remember?
  • Can other factors such as gender and age have an impact on memory?
  • Do people tend to remember certain words more than others?

Performing Your Own Word Memorization Experiment

There are a number of different approaches you could take in conducting your own word memorization experiment. The following are just a few ideas you might explore:

  • Compare random words versus related words. Create two groups of words: one group that is completely random and another that has groups of related words. Ask participants to first complete one trial with the random words, and then complete another trial with the related words. Compare the results of your two trials.

  • Compare results between male and female participants. Have a group of participants perform the memorization activity, and then compare how many the male participants remembered on average to how many the female participants remembered.

  • Try the experiment with gender-associated terms versus gender-neutral terms. For example, create a list of terms related to objects or concepts commonly associated with women. Then create a list of terms not associated with either gender. Administer both tests to a group of participants and compare the results between the men and women. Did women find it easier to remember the gender-associated terms? Did men find it more difficult? Or were the results insignificant?

  • Compare results among different age groups. For example, create a group of school-age children, a group of college students, a group of middle-aged adults and a group of older adults. Give the same word memorization test to each participant and then compare the results of each group. Which group performed the best? Which one performed the worst? What do these results have to say about memory and age?
