Looking at the Figure Below, and Assuming That Extraneous Variables

question 16

Multiple Choice

Looking at the figure below, and assuming that extraneous variables uniquely present during the experimental condition have had the opportunity to influence other behavior, what requirement has not been met to qualify this as a multiple baseline design?

• A) The period of overlap between the experimental condition and the second baseline must be sufficient to permit the response class under the control condition to be influenced by any variables that may do so
• B) Each baseline must be independent
• C) The experimental condition must contact the second baseline as a test of its sensitivity
• D) When the intervention is ongoing in one baseline, the control condition must be ongoing in the other baseline used for comparison
