Nature and scope of synthesis in functional analysis and treatment of problem behavior
Blended FAs are a legit, time-saving twist on classic assessment, and this paper is the field’s first roadmap.
01Research in Context
What this study did
Slaton and her team read every paper they could find on blended, or "synthesized," functional analyses. They wanted to map when and how clinicians mix reinforcers or triggers together during an FA.
They pulled studies from journals, described each blended format, and listed the pros and cons. No numbers were combined; they simply organized the scattered literature.
What they found
Blended FAs come in many flavors. Some fold attention and escape into one test condition. Others mix tangible items with sensory events.
Benefits include faster sessions and clearer results when single contingencies fail. Risks include muddy data and harder treatment matching if the blend clouds the true trigger.
How this fits with other research
Melanson et al. (2023) show the field is already moving toward shorter, blended formats, especially for kids with autism. Slaton’s map sits inside that bigger trend.
Fahmie et al. (2025) argue we should stop treating isolated and blended FAs as rival camps. Slaton’s neutral catalog supports that call for teamwork.
Amador et al. (2024) detail trial-based blends in preschool rooms. Their classroom data extend Slaton’s framework into real-world, time-crunched settings.
Why it matters
If your standard FA stalls or produces weak differentiation, try a quick blended condition instead of quitting. Pick two likely reinforcers, run ten-minute trials, and watch for clear escalation. Slaton’s review gives you the confidence that this shortcut is evidence-based, while newer papers show it works in classrooms and homes.

03Original abstract
Functional analysis (FA) of problem behavior typically includes the contingent delivery of a single reinforcer following problem behavior. However, the FA literature also includes examples of analyses that have delivered multiple reinforcers, arranged multiple establishing operations in one or more test conditions, or both. These analyses have been successfully applied under heterogeneous conditions over several decades and with various synthesized establishing operations and reinforcers, but their qualitative details, outcomes, and contributions to the literature have never been described in a comprehensive manner. The purpose of the current review is to: (a) identify articles that have reported the use of synthesized FAs or treatments; (b) describe the nature and scope of synthesis as it has been applied in the FA literature; (c) analyze outcomes of synthesized FAs and treatments to determine general benefits and disadvantages of synthesis; and (d) offer recommendations for future areas of research.
