How can I participate in Online Studies?

The Olin Paid Subject Pool uses a website called Sona Systems to connect participants to online studies being conducted by Olin faculty and graduate students. After you register as a participant on Sona Systems, you will be able to view, and sign up for online studies by logging in to your Sona Systems participant account.

After you sign-up for a study on Sona Systems, you will be directed to the online study. Upon completing the study, researchers will email your payment for the study, generally a week after the study fills to its maximum number of participants. The system will only allow 100 participants to sign up per day. If you are unable to register, please try again the following day.

I am a foreigner and want to participate in the studies. How can I get paid?

We cannot make cash or gift card payments to participants who are foreign nationals. We are required to process check request payments, or non-cash and non-gift card payments, for participants who are foreign nationals.

Payments made to foreign nationals are considered taxable from the first dollar they receive, and the University is liable for withholding and depositing the tax with the Internal Revenue Service.

Are there any other paid study opportunities?

For additional opportunities for paid studies, please visit the Department of Psychology Research Participation website.
