In the example of the office worker, why is it critical that the goal-setting treatment is introduced for the sales calls and report writing at different times rather than simultaneously? Briefly explain in one to three sentences.
Question: In the example of the office worker, why is it critical that the goal-setting treatment is introduced for the sales calls and report writing at different times rather than simultaneously? Briefly explain in one to three sentences.
Sample answer: Introducing the treatment at different times allows the researcher to isolate the effect of the treatment on each specific behavior. If the treatment were applied simultaneously and productivity increased on both tasks, the improvement could be due to a confounding variable rather than the treatment itself. The staggered introduction demonstrates that the behavior changes only when the treatment is applied, ruling out alternative explanations.
Key points:
- Isolates the effect of the treatment.
- Rules out alternative explanations or confounding variables.
- Demonstrates that behavior change is specifically tied to the timing of the treatment application.
Rubric: The answer should analyze the purpose of the staggered introduction, noting that it helps rule out alternative explanations or confounding variables that might affect both behaviors simultaneously.

In the example of a multiple-baseline design across behaviors involving an office worker, what pattern of results allows a researcher to confidently conclude that the goal-setting treatment caused an increase in productivity?
A researcher is studying an office worker's productivity on two tasks: making sales calls and writing reports. To demonstrate that a goal-setting treatment is the cause of an increase in productivity, arrange the following steps in the correct chronological order.
A researcher is testing a reward system to improve a student's 'on-task behavior' and 'assignment completion.' To determine if the reward system is effective, they use a specific single-subject design. Match each component of the scenario to its corresponding role in this research design.
In a multiple-baseline design across behaviors (such as sales calls and report writing), if the participant's performance on the second behavior improves significantly while it is still in the baseline phase—specifically at the exact moment treatment begins for the first behavior—the researcher can no longer confidently attribute the second improvement to the treatment's specific application.
A school psychologist is tasked with developing an experimental protocol to test if a 'token reward' system increases a student's 'on-time arrival' and 'desk organization.' Which implementation plan should the researcher construct to establish a valid Multiple-Baseline Design Across Behaviors?
In a multiple-baseline design across behaviors involving 'making sales calls' and 'writing reports,' a researcher can validly evaluate the intervention as the cause of improvement in both behaviors even if 'writing reports' increases simultaneously with the 'making sales calls' intervention, provided that both behaviors had stable initial baselines.
A researcher is evaluating whether a goal-setting intervention increases the productivity of an office worker on two distinct tasks: 'making sales calls' and 'writing reports.' Arrange the steps in the correct order to demonstrate a causal relationship between the intervention and the behavior changes.
A researcher evaluates an office worker’s productivity by tracking two distinct behaviors: making sales calls and writing reports. The researcher first establishes baselines for both, then introduces a goal-setting intervention for sales calls first, and later for writing reports. Match each part of this study to its specific logical role in establishing a causal relationship between the intervention and the behavior changes.
A researcher evaluates a goal-setting intervention for an office worker by tracking two separate behaviors: making sales calls and writing reports. After a baseline period for both, the intervention is applied to sales calls first, while report writing remains at its baseline level. Later, the intervention is applied to report writing. To conclude the intervention was effective, which pattern of results is required?
In an example of a multiple-baseline design across behaviors, a researcher measures an office worker's productivity on making sales calls and writing reports. After establishing baselines for both tasks, the treatment introduced sequentially to each task is _____.
In a multiple-baseline design across behaviors, an office worker's productivity on two tasks (sales calls and report writing) is tracked. When the goal-setting treatment is introduced for the sales-call task, report-writing productivity also improves—even though report writing is still in its baseline phase. A researcher evaluating this outcome must conclude that the study has failed to demonstrate _____.
Explain how a multiple-baseline design across behaviors is implemented and how it allows a researcher to determine if a treatment was effective, using the example of an office worker's productivity on two tasks.
Based on the concept of a multiple-baseline design across behaviors, design a specific implementation plan for this study and justify how you would conclude whether the app is effective.
