This is an ABAB design, also known as a reversal design or withdrawal design. It involves measuring baseline behavior (condition A), introducing an intervention (condition B), reversing back to baseline (condition A), and then reintroducing the intervention (condition B) again to see if the behavior changes. In this case, Alex is measuring how often Boatswain chases the cat (condition A), then using the water bottle intervention to try to stop the behavior (condition B), then measuring again to see if the behavior changes (condition A), and finally using the water bottle intervention again to see if it is consistently effective (condition B).
