PSYC-FPX4003 covers ABA's distinctive single-subject research design tradition and precise behavioral measurement methodology, foundational to evidence-based ABA practice.
Single-subject research design in ABA
PSYC-FPX4003 covers single-subject experimental designs distinctive to ABA, examining why this design tradition fits ABA's focus on individualized behavior change rather than group-average outcomes.
Precise behavioral measurement methodology
The course covers rigorous behavioral measurement techniques, examining why precise, operationally-defined measurement is foundational to demonstrating genuine behavior change in ABA practice.

Worked example: why ABA favors single-subject over group designs
- Group design approach: Averages outcomes across many participants, potentially masking how an individual actually responded
- Single-subject design: Tracks one individual's behavior change intensively over time, directly demonstrating whether the intervention worked for that specific person
- Lesson: Since ABA practice is fundamentally about changing an individual's specific behavior, single-subject design provides more directly relevant evidence than a group-average approach that might obscure individual variation

Frequently asked questions
ABA practice is fundamentally focused on changing a specific individual's behavior in a meaningful, measurable way, and a group-average design, which reports an average outcome across many participants, can mask the fact that the intervention worked very well for some individuals and not at all for others — information that's critically important for ABA practice but gets lost in an averaged group result. PSYC-FPX4003 covers single-subject design because it directly and intensively tracks one individual's behavior change over time, providing the kind of individual-level evidence that's actually relevant to ABA's core practice of changing a specific person's specific behavior, rather than establishing what works "on average" across a broader population.
A vaguely described target behavior (like "being disruptive") can be interpreted differently by different observers, making it impossible to reliably and consistently measure whether the behavior is actually occurring, changing in frequency, or genuinely improving over time. PSYC-FPX4003 emphasizes precise, operational definitions (specifying exactly and objectively observable criteria for what counts as an instance of the target behavior) because reliable measurement — which requires this precision — is the entire foundation of ABA's evidence-based approach; without it, there's no valid way to actually demonstrate that an intervention produced genuine behavior change.
