摘要	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 multiple baseline design is a single-subject experimental design that demonstrates functional control by introducing an intervention at staggered time points across two or more baselines — typically across different behaviors, individuals, or settings. Because no withdrawal of treatment is required, it is especially suitable when the target behavior is irreversible or when removing an effective intervention would be unethical.
