ABA Experimental Design Practice Mini-Mock

A set of flashcards covering technical aspects of experimental design, baseline logic, and various types of analysis (parametric, comparative, and component) based on ABA exam review materials.

In a multiple baseline design across three students, what is the analysis if students 2 and 3 increase their target behavior immediately after the intervention is introduced to student 1?

Experimental control has been lost, indicating the design is either ineffective or a confound is interfering.

What is the most significant risk when using a changing criterion design for a behavior with a highly variable baseline ranging from $2\,\text{minutes}$ to $15\,\text{minutes}$?

It will be difficult to show experimental control because the behavior is less likely to stick closely to set criteria (e.g., $7\,\text{minutes}$).

What are the three components of baseline logic?

Prediction, verification, and replication.

How is prediction defined in the context of baseline logic?

Hypothesizing that if an intervention is not introduced, the baseline data will continue as is.

How is replication defined in the context of baseline logic?

Proving an intervention works by reintroducing it over and over again.

How is verification achieved in baseline logic for a single case experimental design?

By verifying the initial baseline prediction, typically by returning to a baseline condition (e.g., removing a bitter tasting polish).

To meet the requirements of verification after a bitter tasting polish reduced nail biting to zero, what action must be taken?

Remove the bitter polish to return to the pre-intervention/baseline stage.

Which type of analysis is used to determine if specific parts of a treatment package (e.g., sitting still vs. raising hands) are necessary?

Component analysis.

What does a parametric analysis investigate?

The dosage or amount of a single intervention.

What characterizes a comparative analysis in experimental design?

Comparing separate interventions that are not part of the same treatment package.

What design is used when introducing free bus passes at different times across three different neighborhoods while measuring ridership?

Multiple baseline design.
