They involve implementing an intervention at different points in time across multiple participants, behaviors, or settings. **Step 2:** One limitation of multiple baseline designs is the potential for **history effects**. History effects occur when extraneous variables, unrelated to the intervention, change during the study and influence the outcome. Since the intervention is implemented at different times for each participant or behavior, it can be challenging to isolate the true effect of the intervention from history effects. **Step 3:** Another limitation is the **lack of generalizability**. Multiple baseline designs are typically used to evaluate the effectiveness of interventions for individual participants or specific contexts. Therefore, the results may not generalize to other populations, settings, or situations. **Step 4:** A third limitation is the **risk of maturation effects**. Maturation effects refer to the natural development or changes in participants over time, which can confound the results. For example, in a study involving children, their cognitive and emotional development may influence the outcome, making it difficult to attribute changes solely to the intervention. **Step 5:** Lastly, multiple baseline designs can be **time-consuming and resource-intensive**. Implementing the intervention at different points in time for each participant or behavior requires more resources and a longer study duration compared to other research designs. **
