Dr. Doe was investigating the reaction to fear stimuli in children ages 8-12 and obtained parental consent for them to participate. In addition to getting the parental consent, Dr. Doe gaveeach child information about the experiment in which they were to participate and asked them if they would please help him by participating in the study. In asking the children if they would participate, Dr. Doe obtained

*a. the child’s assent.
b. the child’s informed consent.
c. passive acceptance.
d. active agreement

A. the child’s assent

Explanation:

The child's assent refers to the affirmative willingness of a child to voluntarily participate in a research study. Children who are under eighteen have no legal capacity to give consent to a research study except through their parents. However, should be they should be involved in the process by having the details of the study explained to them after which they have the right to assent to the study or not. In obtaining assent from minors, adequate efforts must be to ensure the child understands the nature of their participation in the research.

From the question, Dr Doe had already sought the consent of the parents and wants to obtain the children's assent if they will help him by participating in the study. He also had given them all the necessary information needed to understand their role and implication in participating in the research.
