The school psychologist is using the A-B-A design. This involves observing the behavior (A), introducing an intervention (B), then removing the intervention to observe the behavior again (A). Finally, the intervention is introduced again (B) to see if the behavior changes again. This design allows for the observation of whether the intervention has an effect on the behavior.
