Choose a behavioral scenario. From the scenario, what is the dependent variable that should be measured during the study? Given the information in the scenario, what is an operational definition of the target behavior that is objective, clear, and complete?

Scenario

You are a BCBA working for a school district and consulting with the teacher, Mr. Patel, of atypical fourth grade classroom. Mr. Patel has 35 students in his class. One of his students, Jalal, neverraises his hand to volunteer to speak in class during group instruction (six 30-min periods per day). Mr. Patel has identified from individual conversations and Jalal's school work that he knows the answers to the questions, but Jalal is shy and seems to not want to talk in front of others. In discussion with Mr. Patel, you have decided to implement differential reinforcement of high rates (DRH), in which Jalal will earn 10 min of computer time (a highly preferred activity) at the end of the day when he meets his criterion. You will begin with targeting raising his hand and responding to 1 question per day. This number will be increased by 1 when Jalal is responding at the current level for 5 consecutive days. This will continue until Jalal is raising his hand and answering 7 questions per day
