Mand
A verbal operant in which a person asks for what they want or need; it is controlled by a motivating operation and reinforced by receiving the specific thing requested.
A mand is a request. It occurs because of a current motivating operation, such as being hungry, wanting a toy or wanting a hard task to stop, and it is reinforced by getting what was asked for. Saying "juice" when thirsty and receiving juice is a mand. Mands can be spoken, signed, typed, or made with picture exchange or a speech-generating device.
Mands are often among the first verbal skills taught, because they directly benefit the learner and are reinforced by the learner's own motivation. Teaching mands can also reduce problem behavior: when a person can ask for a break or for attention, they may no longer need problem behavior to get it. Functional communication training is built on this idea.
To teach a mand, the RBT waits for or arranges an establishing operation, prompts the response as the plan describes, and gives the specific item, action or removal requested. The reinforcer must match the mand: if a learner signs "ball" and gets praise but no ball, the response is not being reinforced as a mand.
Mands include requests for items, actions, attention, information ("Where is it?") and removal of something ("Stop," "Break").
Example and non-example
| Example | A child wants to go outside, walks to the door, and says "Open." The RBT opens the door. |
|---|---|
| Non-example | A child sees a dog on a walk and says "Dog!" and the RBT says "Yes, a big dog!" The child is naming something they see, which is a tact. |
Don't confuse it with
| Tact | A tact names something the learner contacts and is reinforced by social feedback; a mand is controlled by motivation and reinforced by the specific thing requested. |
|---|---|
| Intraverbal | An intraverbal answers or responds to someone else's words; a mand asks for something the speaker wants. |

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 2At snack time, a child reaches toward crackers that the RBT placed on the counter, in view but out of reach. The RBT waits, the child says "cracker," and the RBT hands over a cracker. Which procedure is the RBT using?
Show answer
B: Incidental teaching. The child's reach (initiation) set up the opportunity, the RBT waited for a request, and the requested item was the reinforcer. These are the core steps of incidental teaching.
- A: In DTT the adult starts each trial with an instruction; here the child started the exchange.
- C: In NCR the item is given on a time schedule regardless of behavior; here it followed the request.
- D: Task interspersal mixes easy and hard targets within instruction; it does not describe this exchange.

- A: A tact names something the speaker contacts and is reinforced by social feedback, not by receiving the item.

- D: An intraverbal answers someone else's words; here the child's wanting juice controlled the response.
