Sidney receives a request to start working with a student. He schedules an observation at the student’s school to conduct a descriptive assessment. Sidney observes the student during class activities for 60 minutes and records how many times the student gets out of his chair (the target behavior). He records 20 instances of getting out of the chair in 60 minutes. The next session, he instructs the teacher to sit the student close by and provide frequent attention when the student is engaged in class activities. He returns to the school after one week and records 5 instances of getting out of the chair in 60 minutes. He looks at the graph and compares his datum before treatment with his datum after treatment, which shows a significant decrease in getting out of seat. Which basic operation of the science of behavior analysis is missing from this example?
