informed consent

Explanation:

When during a study the participants are told in detail about the procedure of the study along with possible risks, benefits and potential consequences and after gaining this knowledge a participant agrees to be a part of the study then it is said to be an informed consent.The medical and research ethics have made it mandatory to get informed consent from the participants before they enrol in any experimental procedure.The informed consent can be given either directly by the participant or if the participant is not in the condition to grant it then the parents or legal guardians can also provide it.Therefore, in the given case Professor Stetson is asking for an informed consent from the participants.
