What defines a mand in verbal operants?

A mand is characterized as a request or demand made by a speaker. This definition centers around the concept that a mand arises when a speaker communicates a need or desire with the expectation that the listener will respond in a way that fulfills that need. This operant is notably about the speaker's motivation, often driven by a specific want or necessity, which distinguishes it from other verbal behaviors.

In contrast, other verbal operants serve different functions. For example, a statement of fact conveys information without necessarily prompting a response related to the speaker's immediate needs. A reiteration presents previously stated information, thus lacking the intrinsic motivation found in a mand. Lastly, a question is designed to solicit information from the listener rather than to express a need or request something directly. Each of these other forms has distinct functions that do not encompass the specific motivational aspect inherent in mands.
