Yоu аre аiding а prоfessоr who is a BCBA doing research in a local clinic. The study includes taking data on engagement behaviors of three participants during circle time. These behaviors include sitting with crossed legs on the floor, correctly responding to each question asked by the instructor, and imitating each motor movement modeled by the instructor. Your professor says this should be a very simple research study and there is very little risk of harm to the participant. Before you start taking data, the BCBA tells you to give the parents a sheet that explains the research procedures and have them sign off on the procedures. After the parents sign off, you begin taking baseline data alongside the BCBA. After taking baseline data, the BCBA has you read through the ethical guidelines. You realize that one element was missing at the beginning of the study. Which element was missed?
