A Behavior Analyst wants to create a recording system to measure the disruptive behavior of a student in the classroom. After recording data on the disruptive behavior, the BCBA notices that the measurement tool they are using is likely overestimating the duration of the behavior being targeted for decrease. Which type of measurement system is the BCBA most likely using?
- Momentary Time Sampling
- Whole Interval Recording
- Inter-response Time Sampling
- Partial Interval Recording
Step 1: Identify the concept being tested
This question tests your understanding of partial and whole interval recording, as well as the advantages or disadvantages of each recording system.
Step 2: Analyze the question
In this scenario, a BCBA uses recording system to measure disruptive behavior when they realize the measurement tool they have used might not be the most accurate reflection of the target behavior. The question asks to identify which measurement tool might overestimate the duration of the behavior.
The Correct Answer is D
Partial Interval Recording is a method of recording behavior that happens at any time during a specified interval of time. Partial interval recording is more likely to overestimate the occurrence of behavior.
- Momentary Time Sampling is a method of recording behavior. During MTS recording, the presence or absence of the behavior is recorded at the end of a specified interval of time.
- Whole Interval Recording is another time-based method of recording behavior. When using whole interval recording, the interval is scored only if the behavior occurred for the entire duration of the interval.
- Inter-response Time refers to the time that can be measured between responses.
