概要	The Pragmatic ABA Design is a single-subject reversal experiment conducted under real-world, naturalistic conditions rather than tightly controlled laboratory settings. It follows the classic baseline (A1) — intervention (B) — withdrawal/return-to-baseline (A2) sequence while deliberately relaxing control conditions to reflect authentic practice environments. This approach prioritizes external validity and clinical utility, making findings directly applicable to schools, clinics, and community settings.	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.
