Measurement - ABA
Disadvantages of continuous measurement - Not useful for bxs that:
-occur at high rates
-are measured via discrete trials
-occur for extended period of time
-are opportunity-based
Trials to Criterion - Measure of the number of response opportunities needed to achieve a
predetermined level of performance criteria. *Can use count, rate, duration, and latency measures
Repeatability - When a behavior can be counted
Instances of a response occur repeatedly through time.
3- Types of repeatability measures: - 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 - 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 - 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 - 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 - 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 - Eating: Measuring bites of food, you would record the time in between each bite.
2- Derivative Measures - 1. Percentage
2. Trials to Criterion
Percentage - a ratio formed by combining the same dimensional quantities, such as count..
2- Definitional Measures - Topography
Magnitude
Topography - Form or shape of response.
Magnitude - 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 - Measurement conducted in a manner such that all
instances of the response class of interest are detected during the observation period.
3 Dimensional Quantities (that can be measured) - repeatability, temporal extent, temporal locus
Advantages of continuous measurement - Useful for bxs that:
