The Functional Independence of Skinner's Verbal Operants: Conceptual and Applied Implications
Skinner’s verbal boxes are only half-independent—check for spillover or gaps before you assume one taught operant will bloom into the rest.
01Research in Context
What this study did
Fryling (2017) looked at Skinner’s six verbal operants: mand, tact, echoic, intraverbal, textual, and transcription.
He asked a simple question: do these operants really work on separate schedules, or do they overlap?
The paper is conceptual—no new data—just a close read of past studies plus Skinner’s own words.
What they found
Some studies show neat splits: a child asks for water but can’t name it, or names it but won’t ask.
Other studies show the opposite: once you teach “water” as a mand, the tact pops up for free.
Fryling says the truth is messy; operants are partly free and partly glued together.
How this fits with other research
Abbott (2013) told us to stop arguing about labels and watch what the verbal community reinforces. Fryling uses that lens to explain why “independence” keeps slipping in and out of view.
Becker et al. (2022) stretch the idea into aphasia labs, showing brain damage can tear mands and tacts apart. Fryling welcomes this as the kind of direct test we still need.
Gilmore et al. (2022) map the same operants onto racist police talk, proving the taxonomy works outside clinic walls. Fryling’s call for tighter measurement fits right in.
Why it matters
If operants are glued together, teaching one should spill into the others—saving you hours. If they split, you must probe each form separately or risk hollow language. Next time you write a verbal program, add a quick post-test: after the mand works, try a tact trial and see what happens. One extra minute tells you which road to take.

03Original abstract
Much has been said about B. F. Skinner's analysis of verbal behavior. This commentary specifically focuses on the functional independence of B. F. Skinner's verbal operants. While researchers have long been interested in this topic, the research literature on this topic has produced mixed results; it has shown that the verbal operants may be both functionally independent and functionally interdependent. This commentary considers the conceptual and applied implications of these mixed findings. The distinction between constructs and events is highlighted, with specific attention to how this distinction relates to the consideration of the verbal operants in behavior analysis. The value of further research on the functional independence of the verbal operants is considered, as well as the type of research studies that might be useful toward developing interventions for individuals with language delays.
