Seven ABA Dimensions and Exam Traps
Key Takeaways
- Baer, Wolf & Risley (1968) defined ABA's seven dimensions: applied, behavioral, analytic, technological, conceptually systematic, effective, generality (mnemonic BAT-CGEA / 'Get A Cab').
- Analytic means a demonstrated functional relation (believable control), not merely that data were collected.
- Technological means procedures are described clearly enough for a trained person to replicate - it has nothing to do with electronic devices.
- Conceptually systematic means procedures are tied to established behavioral principles, not just bundled into a branded package.
- Generality means change endures over time, spreads across settings/people, and emerges in untrained responses - it must be planned and measured, not assumed.
The Foundational Paper and the Seven Dimensions
The seven dimensions come from Baer, Wolf, and Risley (1968), Some Current Dimensions of Applied Behavior Analysis, published in the first issue of the Journal of Applied Behavior Analysis (JABA). They remain the benchmark for what makes an effort genuinely applied behavior analysis rather than just 'using rewards.'
Use a mnemonic to lock the list: BAT-CGEA or the common phrase "Get A Cab" mapping to Generality, Effective, Applied, Conceptually systematic, Analytic, Behavioral, Technological. Whatever device you use, you must recall all seven and, more importantly, define each precisely - because the exam tests the definitions and their confusions, not the list itself.
| Dimension | Precise Meaning | Quick Test Question |
|---|---|---|
| Applied | Targets behavior that is socially significant to the client/society | 'Does this behavior matter to the person and those around them?' |
| Behavioral | Measures actual behavior the person does (observable, measurable), and measures it reliably | 'Are we measuring real behavior, not a label or a proxy?' |
| Analytic | Demonstrates a functional relation (believable experimental control) | 'Did we show the intervention caused the change?' |
| Technological | Procedures described clearly enough to replicate | 'Could a trained person run this exactly from the written plan?' |
| Conceptually systematic | Procedures derived from established behavioral principles | 'Is this tied to reinforcement, extinction, stimulus control, etc.?' |
| Effective | Produces change large enough to be practically/clinically meaningful | 'Is the amount of change worth it to the consumer?' |
| Generality | Change lasts, transfers, and/or spreads to untrained responses | 'Does it hold over time, across settings, and beyond trained targets?' |
The Confusable Pairs (Where Points Are Lost)
Most dimension items are won or lost on four classic confusions. Drill these contrasts:
- Applied vs. Effective. Applied asks whether the target matters (social significance of the goal). Effective asks whether the amount of change is big enough to matter (social significance of the outcome). You can pick a meaningful target (applied) and still fail to move it enough (not effective), and vice versa.
- Behavioral vs. Analytic. Behavioral concerns the dependent variable - are you measuring observable behavior the person actually does, reliably? Analytic concerns the design - does it demonstrate a functional relation? Collecting lots of data is not analytic by itself; you need experimental control (e.g., reversal or multiple baseline).
- Technological vs. 'technology.' Technological means the procedure is written for replication, with every step specified. It is not about iPads, apps, or devices. "Provide prompts as needed" fails the technological test because two implementers could do different things.
- Conceptually systematic vs. 'a package.' Using a branded curriculum is not automatically conceptually systematic. The plan must explain its steps in terms of principles (this is reinforcement, this is errorless prompting via stimulus prompts and fading, this is an MO manipulation) so the procedure coheres with the science.
A fifth high-value point: Generality is the dimension teams most often skip. Acquisition in one room with one therapist is not generality. Generality must be programmed and measured - maintenance over time, transfer across settings/people, and response generalization to untrained but related responses.
Diagnosing the Missing Dimension in a Scenario
Domain A frequently gives a vignette and asks, "Which dimension is lacking?" Train a fast diagnostic:
- Is the goal trivial or someone else's convenience? -> weak on applied.
- Are we measuring a label, trait, or product instead of behavior - or measuring unreliably? -> weak on behavioral.
- Did behavior just happen to change with no comparison or replication to show cause? -> weak on analytic.
- Could another person not replicate the plan from the description? -> weak on technological.
- Are steps applied with no link to behavioral principles? -> weak on conceptually systematic.
- Did behavior change only a tiny, clinically meaningless amount? -> weak on effective.
- Did we stop at acquisition, with no plan for maintenance/transfer/spread? -> weak on generality.
Worked Example. A team teaches a child to request a break using a card. Data show the child now uses the card with the lead therapist in the therapy room, and tantrums dropped sharply during sessions. However: the plan reads "prompt the child to use the card when upset" (no specifics), and the child still tantrums at home and with other staff. Diagnose: the intervention is applied (requesting a break matters), behavioral (card use is observable), and effective within sessions (large drop). It is weak on technological ("when upset" and "prompt" are undefined - not replicable) and weak on generality (no maintenance, no transfer to home or other people). The best 'which dimension is missing' answer is technological or generality, depending on what the stem emphasizes.
High-Yield Distractor Patterns
Memorize the misdirections the exam reuses:
- 'We used a tablet app, so the plan is technological.' -> Wrong. Technological is about replicable written procedure, not devices.
- 'We collected data for months, so the study is analytic.' -> Wrong. Analytic requires a demonstrated functional relation (control), not data volume.
- 'The target is easy to count, so it's applied.' -> Wrong. Applied is about social significance, not measurement convenience.
- 'Change was statistically detectable, so it's effective.' -> Wrong. Effective means practically/clinically meaningful to the consumer, which can differ from statistical significance.
- 'We used a popular branded program, so it's conceptually systematic.' -> Wrong. You must connect steps to behavioral principles.
- 'Behavior improved in the clinic, so we have generality.' -> Wrong. Generality requires durability and spread across time, settings, people, or responses.
Quick exam filter, restated:
- Target matters to client/stakeholders? -> applied.
- Could be replicated from the write-up? -> technological.
- Caused the change (functional relation)? -> analytic.
- Change big enough to matter? -> effective.
- Tied to principles? -> conceptually systematic.
- Measuring real behavior reliably? -> behavioral.
- Lasts/spreads/transfers? -> generality.
Keep applied (target) and effective (outcome) split, and never let 'technological' drift toward gadgets.
A behavior plan states: 'Provide reinforcement and prompts as needed to encourage appropriate behavior.' Two RBTs implement it very differently. Which ABA dimension is most clearly lacking?
A team reports, 'We collected daily frequency data for three months and the behavior decreased, so we have demonstrated that our intervention works.' What is the strongest critique?
Which scenario best illustrates a deficiency in the GENERALITY dimension?
A supervisor praises a plan as 'conceptually systematic' because it uses a well-known branded autism curriculum. The best response is:
