What is the defining feature of a multiple-baseline design across behaviors?

A clinical psychologist wants to determine whether a reinforcement-based intervention improves a client's self-care habits. She tracks two behaviors — frequency of teeth-brushing and frequency of bed-making — during an initial observation period. She then introduces the reinforcement intervention for both behaviors at the same time and observes that both behaviors increase simultaneously. This procedure allows her to rule out the possibility that an outside event, rather than the intervention, caused the improvements.

A researcher is using a multiple-baseline design across behaviors to help a student improve three distinct classroom behaviors: raising their hand, staying in their seat, and completing assignments. Match each part of the experimental procedure with its corresponding implementation in this study.

A behavioral researcher is designing a study to treat three distinct anxiety behaviors in a single patient. To establish causality using a multiple-baseline design across behaviors, organize the researcher's methodological steps in the correct logical sequence.

A researcher is developing a protocol to investigate if a self-monitoring intervention effectively improves three distinct, unrelated academic behaviors—active note-taking, textbook highlighting, and participation in discussion forums—for a single student. To create a valid multiple-baseline design across behaviors that demonstrates experimental control, which of the following experimental architectures should the researcher construct?

Multiple-Baseline Design Across Behaviors Example

In a multiple-baseline design across behaviors, the researcher introduces the intervention for all of the participant's targeted behaviors at the same time.

A researcher implements a multiple-baseline design across behaviors to target a child's 'sharing' and 'verbal-requesting.' The intervention is applied to sharing at session $5$ and to verbal-requesting at session $10$. If verbal-requesting levels increase significantly at session $5$—before the treatment is applied to it—the researcher must conclude that the results fail to establish _____.

A clinical psychologist uses a multiple-baseline design across behaviors to help a client. Match each research design component to its corresponding application in the study.

In a multiple-baseline design across behaviors targeting a single participant's sales calls and report writing, an increase in productivity that corresponds only to the staggered introduction time of the intervention for each behavior allows researchers to establish _____.

A researcher is planning to evaluate the effectiveness of a productivity intervention using a multiple-baseline design across behaviors. Order the steps from first to last to ensure the study can successfully establish causality.

Describe the core structure of a multiple-baseline design across behaviors and explain how this design helps researchers establish causality.

Based on the principles of a multiple-baseline design across behaviors, what specific pattern of results must the researcher observe to provide clear evidence that the token-reward intervention caused the improvement in the worker's productivity?

A clinical psychologist is planning a multiple-baseline design across behaviors to help a child reduce three different habits: nail-biting, thumb-sucking, and hair-pulling. After establishing multiple baselines for all three of these dependent variables, what specific methodological step must the psychologist take next to properly apply this design?
