Measurement – ABA Exam Questions With
Revised Answers
3 Dimensional Quantities (that can be measured) - answer✔✔repeatability, temporal extent,
temporal locus
Repeatability - answer✔✔When a behavior can be counted
Instances of a response occur repeatedly through time.
3- Types of repeatability measures: - answer✔✔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 - answer✔✔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 - answer✔✔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 - answer✔✔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.
2-Types of Temporal Locus - answer✔✔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 - answer✔✔Eating: Measuring bites of food, you would record the time in
between each bite.
Percentage - answer✔✔a ratio formed by combining the same dimensional quantities, such as
count.
Trials to Criterion - answer✔✔Measure of the number of response opportunities needed to
achieve a predetermined level of performance criteria. *Can use count, rate, duration, and
latency measures.
Magnitude - answer✔✔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 - answer✔✔Measurement conducted in a manner such that
all instances of the response class of interest are detected during the observation period.
Advantages of continuous measurement - answer✔✔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 - answer✔✔Not useful for bxs that:
-occur at high rates
-are measured via discrete trials
-occur for extended period of time
-are opportunity-based
Discontinuous measurement procedures - answer✔✔Measurement conducted in a manner such
that some instances of the response class of interest may not be detected.
