ABA Chapter 9 Revised Exam with 100% Correct answers For the multiple baseline design, describe the general sequence of events. *Ans* Assuming accurate measurement and proper experimental control of relevant variables (i.e., the only environmental factor that changes during the course of the experiment should be the presence or absence of the independent variable), each time a behavior changes when, and only when, the independent variable is introduced, confidence in the existence of a functional relation increases. The suggested number of replications needed in any design in ultimately a matter to be decided by the consumers of the research in order to demonstrate a functional relation. An experiment using multiple baseline design must contain the minimum number of replications necessary to convince those who will be asked to respond to the experiment and to the researchers' claims (e.g. teachers, parents, administrators, etc.). For the multiple baseline design, describe the logic behind why it permits a demonstration of a functional relation. *Ans* depends on two occurrences: 1. The behavior(s) still in baseline showing no change in level, variability, or trend while the behavior(s) in contact with the independent variable changes and 2. Each behavior changes when and only when the independent variable has been applied to it. You can only tell if there's a functional relation of the behavior changes when and only when intervention is introduced. Describe what types of behaviors you should use a multiple baseline design to address. *Ans* can be used with behaviors that are irreversible or when its unethical to reverse the treatment. State the minimum number of baselines recommended for proof of a functional relationship when using this design. *Ans* is 3 and it is necessary to ensure that the data are stable before introducing treatment. Summarize the assumptions to consider when planning multiple baseline designs. *Ans* - There is a functional relationship between the independent variable and dependent variable - The implementation of the independent variable will result in a change in rates of the dependent variable Summarize the procedural guidelines to consider when planning multiple baseline designs. *Ans* 1. Select independent, yet functionally similar, baselines: demonstration of a
