Welcome to the Sleep-Dependent Memory Experiment!

This experiment will allow you to test your ability to consolidate declarative memory during sleep. In the first session, you will learn a set of word pairs and your memory will be tested for the pairs. In the second session, you will receive a second test on the words. Importantly, you should complete the first session sometime in the evening, at least an hour before your habitual bed time, and you should complete the second session in the morning, at least 45 minutes after you wake.

Below, you will find files that you can download for every aspect of the experiment. We recommend that you download the two experiment files and the two score sheets and put them in a folder on your desktop when you are ready to begin the experiment. We further recommend that you wait to download the answer key until you have completed the experiment.

Materials for Session 1, the Evening Session
This is a powerpoint file. When you click on the link, you will see a window that will ask if you want to open the file or save the file. We recommend that you open the file first and then save it to your desktop.

Materials for Session 2, the Morning Session
This is also a powerpoint file. As with the first one, when you click on the link, you will see a window that will ask if you want to open the file or save the file. We recommend that you open the file first and then save it to your desktop.

Experiment Score Sheets
These are word documents that you can use to record your responses on the test. You can either type your responses into the individual files and save them on your computer or you can print them out and write your responses. Alternatively, you may find it easier to simply write your responses on a piece of notebook paper, napkin, cereal box, or banana peel.

Answer Key
You should download this file after you have completed the entire experiment. This is a word document that will enable you to score your responses on both tests and to calculate your sleep memory score.
