A reversal design involves alternating between a baseline phase and a treatment phase, typically with one or more reversals back to baseline. In this case, the A-B-A-B pattern involves two reversals from baseline to treatment and back to baseline. This allows the researcher to assess the effects of the treatment by comparing the participant's behavior during the treatment phase to their baseline behavior, and then seeing if the behavior changes back to baseline when the treatment is removed.
