Measurement – ABA Exam Study Guide with Complete Solutions

Measurement – ABA Exam Study Guide with Complete Solutions 3 Dimensional Quantities (that can be measured) - Answer️️ -repeatability, temporal extent, temporal locus Repeatability - Answer️️ -When a behavior can be counted Instances of a response occur repeatedly through time. 3- Types of repeatability measures: - Answer️️ -1.Count (add up the bx's or items) 2. Rate (AKA frequency) 3. Celeration/Frequency (Count per unit of time) *This is the same thing as frequency Temporal Extent - Answer️️ -When the DURATION of the behavior can be measured. Every instance of bx occurs during SOME amount of time. Only 1 type of temporal extent measure: Duration When to use duration measurement - Answer️️ -You want to measure the amount of time of a bx For bx's that occur for too long/too short of time. High rate behaviors. Temporal Locus - Answer️️ -Measuring the TIME at which behavior occurs LOCUS= Point in time Temporal Locus examines when an instance of behavior occurs in respect to other events. ©SOPHIABENNETT_2024/2025 EXAM SERIES Monday, September 2, 2024 9:52 AM Page | 2 2-Types of Temporal Locus - Answer️️ -1. Response Latency (aka latency)- Time between the onset of a stimulus and initiation of a response. Latency should be used when you want to measure how much time occurs between an opportunity to emit a bx and when the bx is initiated. 2. Interresponse Time: (IRT) Amt of time that elapses between 2 consecutive instances of a response class. (i.e. same exact bx's. IRT Example - Answer️️ -Eating: Measuring bites of food, you would record the time in between each bite. 2- Derivative Measures - Answer️️ -1. Percentage 2. Trials to Criterion Percentage - Answer️️ -a ratio formed by combining the same dimensional quantities, such as count. Trials to Criterion - Answer️️ -Measure of the number of response opportunities needed to achieve a predetermined level of performance criteria. *Can use count, rate, duration, and latency measures. 2- Definitional Measures - Answer️️ -Topography Magnitude Topography - Answer️️ -Form or shape of response. Magnitude - Answer️️ -Force/intensity/severity of behavior. Certain responses need be emitted at specific levels of intensity. Example: Volume of voice differing in the library vs. in a crowded store. ©SOPHIABENNETT_2024/2025 EXAM SERIES Monday, September 2, 2024 9:52 AM Page | 3 Continuous Measurement Procedures - Answer️️ -Measurement conducted in a manner such that all instances of the response class of interest are detected during the observation period. Examples of continuous measurement - Answer️️ -Event recordi
