By Matt Harrington, BCBA · Behaviorist Book Club · Clinical decision guide
One of the most consequential decisions a behavior analyst makes is not just what intervention to use, but how to approach the clinical question in the first place. For matching, the difference between an evidence-based, individualized approach and a traditional, protocol-driven one can significantly impact outcomes.
This guide lays out the key factors side by side to support your clinical decision-making.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Controlling stimulus relation | Identical matching: sample and comparison are perceptually identical; responding controlled by perceptual similarity | Non-identical matching: sample and comparison are perceptually distinct but share category membership or functional relation |
| Cognitive demand | Identical matching: perceptual discrimination; requires attention to shared physical features | Non-identical matching: conceptual discrimination; requires abstract grouping beyond perceptual similarity |
| Instructional entry point | Identical matching: first matching form targeted; appropriate for earliest visual discrimination learners | Non-identical matching: builds on established identical matching; introduced after identity matching is mastered |
| Error pattern differences | Identical matching: errors typically reflect position bias or insufficient attention to sample | Non-identical matching: errors often reflect perceptual similarity biases or undeveloped category concepts |
| Generalization requirements | Identical matching: generalize across novel objects with the same identity; requires varied exemplar training | Non-identical matching: generalize across novel members of the same category; requires multiple exemplars from each category |
| Functional relevance | Identical matching: prerequisite for PECS discrimination, picture identification, symbol use | Non-identical matching: supports categorization, intraverbal category responses, and academic classification skills |
The ABA Clubhouse has 60+ on-demand CEUs including ethics, supervision, and clinical topics like this one. Plus a new live CEU every Wednesday.
Use this framework when approaching matching in your practice:
Does the data support a need for intervention? Is there a meaningful impact on the individual's quality of life, safety, or access to reinforcement?
YES → Proceed to assessment NO → Document reasoning, monitor
A functional assessment should guide intervention selection. Avoid defaulting to standard protocols without individual analysis. Consider environmental variables, setting events, and private events.
YES → Select evidence-based approach matched to function NO → Complete assessment first
Goals should be co-developed. Assent and informed consent are ethical requirements. The individual's preferences and values matter in selecting both goals and methods.
YES → Proceed with collaborative plan NO → Engage in shared decision-making
This course covers the clinical and ethical dimensions in detail with structured learning objectives and CEU credit.

All behavior-analytic intervention is individualized. The information on this page is for educational purposes and does not constitute clinical advice. Treatment decisions should be informed by the best available published research, individualized assessment, and obtained with the informed consent of the client or their legal guardian. Behavior analysts are responsible for practicing within the boundaries of their competence and adhering to the BACB Ethics Code for Behavior Analysts.
