That is, if the study takes up to 30 minutes one credit is given, but if it lasts between 30 minutes and an hour, two credits are issued. Note that students will not be credited for participation in studies taking place after the end of classes, because there must be time for recording and crediting their points. All cards should be signed immediately, not the next day or the next week. In addition to the cards, the researcher must keep a separate record of the same information on spreadsheets that can be down loaded from the Subject Pool web page. The spreadsheet must be submitted after each course is finished even if the study is not yet complete.
Students have the right to decline to participate in any study, or to withdraw at any time.
However, to receive credit they must go through the debriefing. Refusals or withdrawals occur very rarely, at least once students actually appear for the study, but they should be treated with the same dignity and respect as those who participate fully, and the researcher should answer their questions as thoroughly and readily as any others. If a subject does not come at the appointed time, no credit will be given, but in the past no penalties were given either. If the problem of no-shows becomes severe, some sanctions may be possible, e.g., the loss of other earned credit. Suspension of privileges Use of the subject pool is a privilege.
