Mands serve what purpose for the speaker?

Mands are a specific type of verbal operant defined in behavior analysis, particularly in the context of Applied Behavior Analysis (ABA). They are characterized by their function of expressing the speaker's need or desire for reinforcement. When an individual makes a mand, they are directly requesting something that will satisfy a particular need or want, such as asking for food, attention, or assistance.

In this context, mands serve the purpose of directly serving the speaker by allowing them to communicate their needs and desires to others. This means that when someone uses a mand, they are not just sharing information or making observations; they are actively engaging in a request that is intended to fulfill their own requirements.

The other options involve different types of verbal behavior. For instance, asking questions primarily relates to gaining information rather than expressing a need. Providing information typically aligns with tacts or intraverbals, which serve to convey knowledge or facts. Commenting on one's surroundings also relates to descriptive language rather than the direct fulfillment of personal needs.

Therefore, the correct answer highlights the essential role of mands in facilitating the speaker's ability to obtain what they require or desire, emphasizing their functional purpose in communication.
