SONA has been used to recruit and schedule partipants for several different types of studies. There are two basic types: course credit (for students in some of CLPS courses) and paid. Every study that gives course credit is accessed through SONA, whether online or in a lab. SONA provides information about the studies and a mechanism for scheduling time slots for the in-lab studies or links to online studies. A potential participant would need to visit SONA to create an account and gain access to the list of studies.
