Measurement – ABA Exam Study Guide

Measurement – ABA Exam Study Guide 3 Dimensional Quantities (that can be measured) - Correct Answer️️ -repeatability, temporal extent, temporal locus Repeatability - Correct Answer️️ -When a behavior can be counted Instances of a response occur repeatedly through time. 3- Types of repeatability measures: - Correct 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 - Correct 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 - Correct 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 - Correct Answer️️ -Measuring the TIME at which behavior occurs TITLE: EMILLYCHARLOTTE 2024/2025 ACADEMIC PERIOD OWNER: EMILLYCHARLOTTE COPYRIGHT STATEMENT: ©2024 EMILLYCHARLOTTE. ALL RIGHTS RESERVED FIRST PUBLISHED: SEPTEMBER 2024 2/13 LOCUS= Point in time Temporal Locus examines when an instance of behavior occurs in respect to other events. 2-Types of Temporal Locus - Correct 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 - Correct Answer️️ -Eating: Measuring bites of food, you would record the time in between each bite. 2- Derivative Measures - Correct Answer️️ -1. Percentage 2. Trials to Criterion Percentage - Correct Answer️️ -a ratio formed by combining the same dimensional quantities, such as count. Trials to Criterion - Correct 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 - Correct Answer️️ -Topography Magnitude TITLE: EMILLYCHARLOTTE 2024/2025 ACADEMIC PERIOD OWNER: EMILLYCHARLOTTE COPYRIGHT STATEMENT: ©2024 EMILLYCHARLOTTE. ALL RIGHTS RESERVED FIRST PUBLISHED: SEPTEMBER 2024 3/13 Topography - Correct Answer️️ -Form or shape of response. Magnitude - Correct 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. Continuous Measurement Procedures - Correct 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 - Correct Answer️️ -Event recording, (i.e. rate/frequency, count) timing (i.e. duration, IRT, latency) Advantages of continuous measurement - Correct Answer️️ -Useful for bxs that: -are free operants -have a discrete beginning & end -require minimal displacement of the organism in time/space -can be emitted at any time -do not require much time for completion Disadvantages of continuous measurement - Correct Answer️️ -Not useful for bxs that: -occur at high rates -are measured via discrete trials -occur for extended period of time -are opportunity-based TITLE: EMILLYCHARLOTTE 2024/2025 ACADEMIC PERIOD OWNER: EMILLYCHARLOTTE COPYRIGHT STATEMENT: ©2024 EMILLYCHARLOTTE. ALL RIGHTS RESERVED FIRST PUBLISHED: SEPTEMBER 2024 4/13 Discontinuous measurement procedures - Correct Answer️️ -Measurement conducted in a manner such that some instances of the response class of interest may not be detected. Examples of Discontinuous Measurement Procedures - Correct Answer️️ -Time sampling methods, interval recording (i.e. Partial, whole, momentary sampling) Advantages of Discontinuous Measurement - Correct Answer️️ -Useful for bxs that: -occur at high rates -occur for long durations of time -are measured via discrete trials -are measured via percentage Disadvantages of Discontinuous measurement - Correct Answer️️ -Not useful for behaviors that: -Are free operant -It is important to obtain every occurrence of the behavior -Time Sampling... remember, this is DIScontinuous measurement procedure. Event Recording - Correct Answer️️ -Methods that record the number of times a response occurs. Timing - Correct Answer️️ -Methods to measure include: a. Duration b. Response Latency TITLE: EMILLYCHARLOTTE 2024/2025 ACADEMIC PERIOD OWNER: EMILLYCHARLOTTE COPYRIGHT STATEMENT: ©2024 EMILLYCHARLOTTE. ALL RIGHTS RESERVED FIRST PUBLISHED: SEPTEMBER 2024 5/13 c. Interresponse time Time Sampling - Correct Answer️️ -Variety of methods for recording behaviour during intervals or at specific moments in time Gives an approximation of the actual instances of behaviour 3- Forms of Time Sampling - Correct Answer️️ -1. Whole Interval Recording 2. Partial Interval Recording 3. Momentary Time Sampling How to design and implement whole interval recording - Correct Answer️️ -1. Divide the observation period into a series of brief intervals (5-10 seconds) 2. At the end of each interval record whether the target bx occurred throughout the interval. 3. Reporting Data = always a percentage. Advantages of Whole Interval - Correct Answer️️ -Best for measuring bx you want to INCREASE Why? Because if you want to increase a bx you choose a conservative method which is whole interval. Disadvantages of Whole Interval - Correct Answer️️ -Not good for behaviors you want to decrease. *You are required to observe the target bx throughout the ENTIRE interval. How to Design and implement partial interval recording - Correct Answer️️ -1. Divide observation period into brief time intervals TITLE: EMILLYCHARLOTTE 2024/2025 ACADEMIC PERIOD OWNER: EMILLYCHARLOTTE COPYRIGHT STATEMENT: ©2024 EMILLYCHARLOTTE. ALL RIGHTS RESERVED FIRST PUBLISHED: SEPTEMBER 2024 6/13 2. At the end of each interval, record whether the target bx occurred at ANY POINT during the interval. Advantage of partial interval - Correct Answer️️ -Easy to measure multiple behaviors concurrently best for measuring bx's you want to decrease Why? B/c if you want to decrease a bx you want to select a more conservative method. Disadvantages of Partial Interval - Correct Answer️️ -Not good when you want to increase a bx Must observe the target bx throughout the entire inte
