A school-based BCBA chooses to collect data only during the last 5 minutes of each class period due to limited time. This approach is an example of:
Answer: Probe data collection
Probe data collection involves measuring behavior at selected, limited opportunities rather than during every opportunity, useful when continuous measurement is impractical.
Which of the following is a limitation of using only indirect assessment methods (interviews, rating scales) for an FBA?
Answer: They rely on informant recall and may not accurately reflect actual behavior
Indirect methods depend on informant memory and perception, which can introduce bias and may not accurately represent what is actually occurring.
A BCBA notices that two observers' IOA drops over time during a long observation. This is most likely due to:
Answer: Observer drift
Observer drift occurs when observers gradually change their application of operational definitions over time, reducing agreement.
An operational definition of a target behavior should include which of the following characteristics?
Answer: Observable, measurable, and complete (OTC)
A good operational definition must be observable (seen or heard), measurable (quantified), and complete enough to distinguish the behavior from similar responses.
A BCBA uses a reversal (ABAB) design during assessment to demonstrate experimental control. Phase B is typically the:
Answer: Treatment/intervention phase
In an ABAB design, A phases are baselines and B phases are treatment/intervention phases, alternating to demonstrate the behavior changes due to the intervention.
When a BCBA uses a multiple baseline across settings design, behavior change is demonstrated by:
Answer: Introducing the intervention sequentially across settings while others remain in baseline
A multiple baseline across settings staggers the introduction of the intervention across settings sequentially, demonstrating the behavior changes only when the intervention is introduced.
A BCBA calculates a 'rate' measure by dividing the count of behavior by:
Answer: The observation time period
Rate is calculated as count divided by the observation time period (e.g., responses per minute), allowing comparison across sessions of different lengths.
