Final answer:
A face-to-face meeting with the researcher before volunteering is not a requirement for informed consent. Informed consent involves participants being fully aware of the study details, risks, and their right to withdraw at any time.
Step-by-step explanation:
The requirement that is not a part of informed consent is that participants need to have a face-to-face meeting with the researcher before volunteering. Informed consent involves ensuring that participants are fully aware of the study's nature, risks, benefits, and voluntary participation. It does not necessarily require a personal meeting before participation.Components of informed consent include information about the stimuli participants will encounter, understanding the risks and potential benefits involved, the approximate duration of the study, and the assurance that participants can withdraw at any time without penalty. Participants must sign an informed consent form, or for those under 18, their guardians must do so.It is crucial for the ethical conduct of a study that participants are aware that their involvement is voluntary, that their confidentiality will be preserved, and that they understand the full extent of what participation entails.
