What type of verbal operant is displayed when saying "chicken" leads to getting a piece of chicken?

The correct answer is that this scenario illustrates a mand. A mand is a type of verbal operant that involves a speaker requesting something they want or need. In this example, when saying "chicken" leads to obtaining a piece of chicken, it indicates that the individual is using language to communicate a desire or need for chicken.

In contrast, a tact refers to labeling or describing something that an individual sees, hears, or experiences, without necessarily desiring anything in return. An echoic involves repeating what someone else has said, which does not involve any request for an item but rather mimics the sounds of another's speech. Intraverbals are responses that are related to prior verbal behavior but do not have a direct correspondence with the items being referred to.

Thus, the act of saying "chicken" to get a piece of chicken exemplifies requesting, making it a clear representation of a mand.
