Verbal operants
Categories of verbal behavior defined by what controls them and what reinforces them, not by the words used; the elementary ones include the mand, tact, echoic and intraverbal.
B. F. Skinner's analysis of verbal behavior classifies language by its function: what antecedents evoke it and what consequences maintain it. The same word can belong to different verbal operants depending on these conditions. The 40-hour training curriculum gives four elementary verbal operants as examples an RBT should understand:
- Mand: a request, controlled by a motivating operation and reinforced by the specific thing requested.
- Tact: a label or comment, controlled by a nonverbal stimulus and reinforced socially.
- Echoic: a repetition of someone else's speech, with point-to-point correspondence.
- Intraverbal: a response to someone else's words with different words, such as answering a question.
Other operants in Skinner's analysis include textual behavior (reading written words aloud) and transcription (writing or spelling words that are spoken). Verbal behavior is not limited to speech; sign language, picture exchange and devices count when they function in these ways.
Knowing the verbal operants helps an RBT deliver the right consequence and understand why a learner who can say "water" when shown a picture still may not ask for water when thirsty. Each operant usually needs to be taught on its own, and the supervisor's plan specifies which operant each target is meant to build.
Example and non-example
| Example | A child learns to say "ball" as an echoic, then learns to say it to label a picture (tact), to ask for the ball (mand) and to answer "What do you kick?" (intraverbal). The plan lists each as a separate target. |
|---|---|
| Non-example | Grouping words by topic, such as animals, foods and colors, sorts vocabulary by content, not by verbal operant. |
Don't confuse it with
| Verbal prompt | A verbal prompt is spoken help given by the RBT; verbal operants are categories of the learner's own verbal behavior. |

Question 1Which situation would test whether a client can mand?
Show answer
A: Holding a favorite snack in view but out of reach and waiting for a request. A mand is a request controlled by motivation for a specific item or action. Having a wanted item visible but out of reach sets up an opportunity to request it.
- B: Naming a pictured item tests a tact.
- C: Repeating a spoken model tests an echoic.
- D: Answering a question with no item present tests an intraverbal.

Question 2An RBT places three pictures on the table and says, "Touch the cup." Which skill does this item assess?
Show answer
B: Listener (receptive) responding. Following a spoken instruction by touching the named item is listener (receptive) responding; the client responds to what another person says.
- A: A tact is naming something the client sees, which this item does not ask for.
- C: A mand is a request for something the client wants.
- D: An intraverbal is a verbal answer to someone else's words with no item present to name.

Question 3A child says "juice" because they want juice, and the adult gives them juice. Which verbal operant is this?
Show answer
B: Mand. A mand is a request controlled by a motivating operation (wanting juice) and reinforced by the specific thing asked for (getting juice).
- A: A tact names something the speaker contacts and is reinforced by social feedback, not by receiving the item.
- C: An echoic repeats what someone else just said; no one said "juice" first.
- D: An intraverbal answers someone else's words; here the child's wanting juice controlled the response.
