The Positive Psychology Center at the University of Pennsylvania, headed by Dr. Martin E. P. Seligman, needs you for our online research studies.
Participation in any of the studies is completely voluntary, and you may drop out of them at any time. These studies all comply with university and U.S. government guidelines for the protection of human subjects and of your online privacy.
These studies may include multiple questionnaires and repeat visits, with possible assignments between visits to the web site. You'll be notified by email whenever your continuing participation in the study is needed.
