Podsumowanie	The single-blind ABAB design is a single-case experimental approach that sequences two baseline phases (A) and two intervention phases (B) to demonstrate experimental control over a target behavior, while keeping one party — typically the outcome assessor or the participant — unaware of current phase assignment. This blinding procedure reduces observer bias or demand characteristics, strengthening the internal validity of the reversal logic.	The ABA design is a single-subject experimental design that demonstrates experimental control through three sequential phases: a baseline phase (A1), an intervention phase (B), and a return-to-baseline withdrawal phase (A2). By removing the intervention in the final phase and observing whether behavior reverts toward baseline levels, researchers establish a functional relationship between the treatment and the target behavior for an individual participant.
