Adults, 18 to 30 years of age, are invited to participate in an online 2-Session Study with a Researcher using a secure University connection and Zoom teleconference link. Each session will be about 45 - 60 minutes in duration and occur on different days. You can sign up for the first session below. The second session can be scheduled at the end of your first session. Both sessions must occur within 14 days or less of each other. Please, ONLY sign up if you have the ability to attend two separate online sessions within 14 days or less of each other.

Study Name and Description:
In this study, participants will be asked to remember colored squares and sounds presented together or separately. When a single colored square or tone is presented, participants must determine if it’s same or different from the ones that were just seen or heard. A puzzle task or a number recall task will be administered at the end of each session.

The following are required in order to participate:
A stable Internet connection; a desktop or laptop computer with webcam and audio capabilities. Please use an audio system (over-the-ear headphones; earbuds; integrated speaker system; external speaker system) that provides you with the best sound quality and can be adjusted for volume.
