Children's Capacity to Consent to Participation in Psychological Research: Empirical Findings

This is a series of studies that attempted to obtain some systematic data on the capacity of children between the ages of 5 and 12 to consent to psychological research. Most of the children understood all or most of what they were asked to do in a psychology study, but few children below the age of 12 fully understood or believed that their performance would be confidential. Similarly, most children appeared to know that they could end their participation in the study, but younger children were not clear on the details of how to accomplish this, and many of all ages believed that there would be some negative consequences if they asked to stop. Moreover, obtaining prior permission from parents, while providing protection for the children, appeared to introduce additional pressure on them to agree to participate in the research and to continue once they had agreed. It is concluded that in general children of these ages do have the capacity to meaningfully assent to participation in research, but that there are substantial problems in guaranteeing that they are able to make this decision freely.
