study a participant must have participated in in not order to participate in a study). If set to Yes, researchers may choose as many pre-requisites and/or disqualifiers for their studies as they like (they may opt not to). If set to No, researchers are never given such an option, and pre-requisites and disqualifiers are not allowed. Pre-Requisite Enforcement Yes or No value indicating whether the system should Leniency be lenient in enforcing pre-requisites. If set to Yes, a participant may sign up for a study that has a as long as they are for the signed up study also. If set to No, the system will be strict and a participant must have for the received credit pre-requisite study before they may sign up. An example where leniency might be useful is if on a Monday, a participant signs up for Study A for Wednesday, and they want to sign up for Study B for Friday. Study B has a pre-requisite of Study A. If this value is set to Yes, the participant is allowed to sign up for Study B because they are signed up for Study A. If the value is set to No, they cannot sign up for Study B until they have received credit for Study A (which will likely occur after they participate in Study A, on Wednesday). Course Restriction Feature Yes or No value indicating if the course restriction feature should be made available. If set to Yes, researchers can choose to limit participation in their studies to participants enrolled in specified courses. If a participant is not enrolled any of the specified courses, the study will not show up on the list of available studies. Such restrictions are particularly useful when the participants span a wide range of courses, and certain studies should be off-limits to participants who may have learned about the details of a certain type of research in their courses, such that their participation may affect the integrity of the research. Timeslot Restriction This setting may be enabled so the system enforces restrictions on the number of experimental timeslot available. It can be restricted on a per-researcher basis (a researcher has a specified number of hours to allocate across all their studies), per-P.I. basis, or basis (restrictions are linked to a specific study). Only one type of restriction may be chosen If Multiple Researchers per Study is enabled, then the per-researcher basis for restriction is not
