Podsumowanie	The crossover ABAB design is a single-subject experimental design that alternates between baseline (A) and intervention (B) conditions twice within the same participant. By withdrawing and reintroducing the treatment, the researcher can demonstrate experimental control: if behavior improves with B and reverts with A, the causal link between the intervention and the outcome is established without a separate control group.	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.
