RBT Exam Study Guide: Measurement in ABA

Significance of Measurement in ABA

Measurement is crucial for tracking a learner's progress and making data-based decisions to improve client outcomes.

RBT Task A-1

Prepare for Data Collection by reviewing target behaviors and gathering necessary materials for accurate data collection.

Continuous Measurement

Recording every occurrence of a behavior when feasible.

Count

The total number of times a behavior occurs.

Frequency/Rate

The number of times a behavior occurs over a specific time period.

Response Latency

The time between the onset of a stimulus and the start of the behavior.

Interresponse Time (IRT)

The time between two occurrences of a behavior.

Duration

The total time a behavior occurs.

Discontinuous Measurement

Records some occurrences of a behavior, not all, when it's not feasible to observe every instance.

Whole Interval Recording

Recording if a behavior occurred for the entire interval during equal time periods.

Partial Interval Recording

Recording if a behavior occurred at any point during an observation interval.

Momentary Time Sampling

Observing if a behavior is happening at the end of predefined intervals.

Permanent-Product Recording

Measuring behavior based on its end product rather than the behavior itself.

Graphing Data

Using graphs to display the relationship between behavior and time for analysis.

Observable and Measurable Behavior

Behaviors should be described using clear, objective terms that can be observed and quantified.

Dead Man’s Test

If a dead man can do it, it’s not a behavior; implies behaviors must be active and observable.

What does ABC stand for?

Antecedent, Behavior, Consequence - the three-term contingency that is the basic unit of analysis in ABA.

Consequence

A stimulus change that follows a behavior of interest.

Antecedent

A stimulus change that occurs prior to the behavior of interest.

Stimulus

An environmental condition or stimulus change existing or occurring prior to a behavior of interest
