Discontinue: Do not discontinue. Administer all four items to examinees in the order in which they appear hear. Discontinue each item after the examinee either has identified the target object or has asked 20 yes/no questions without identifying the target object. Do not reveal the target object if the examinee has failed to identify it after asking 20 questions. Administration and Recording: Position the stimulus booklet flat on the table in a horizontal (landscape) position directly in front of the examinee's midline, with the pictures facing the examinee. Say, "Now we are going to do something where you ask me questions. I have picked one of these pictures, and I want you to figure out which one it is by asking me questions. You can only ask questions that I can answer yes or no. You can ask any question at all, as long as I can answer it yes or no. Try to guess the picture that I have picked with the fewest number of questions you can. I'm going to write down your questions so I can remember them. Go ahead and ask me the fewest number of yes/no questions you can to figure out which picture I have selected." Record verbatim each of the examinee's questions in the order that they are asked. Answer "Yes" if the examinee's questions encompasses or identifies the target item or "No" if it does not. Circle Y (for yes) or N (for no) to indicate your answer to each of the examinee's questions. Whether or not the examinee correctly identifies the target object for Item 1 after 20 yes/no questions or fewer, say, "Good. Let's try the next one. I've picked a new picture, and I want you to ask me the fewest number of yes/no questions you can to figure out which one it is. Go ahead."
