Currently Active Studies
Number Comparison
What you’ll do: You will see single digits on the screen one at a time and decide, as quickly and accurately as you can, whether each number is smaller or larger than 5, using two keys on your keyboard.
Time: About 8–10 minutes • Credit: 1 SONA credit
Requirements: A desktop or laptop computer (not a phone or tablet), a physical keyboard, and a modern browser (Chrome, Firefox, Edge, or Safari).
What to Expect
Before you begin, you will read an informed consent form describing the study, what your participation involves, and your rights as a participant. You may stop at any time without penalty. Most tasks ask you to respond quickly and accurately to items on the screen, so it helps to find a quiet space where you can work without interruption for the full session.
Eligibility
Unless a specific study states otherwise, participants must be at least 18 years old and have normal or corrected-to-normal vision. Some studies have additional requirements, which will be listed on the study’s consent page.
Questions or Concerns
If you have questions about a study, contact Dr. Brian Rivera at rivera21@stolaf.edu. Questions about your rights as a research participant may be directed to the St. Olaf College Institutional Review Board (IRB).
