Which term describes the act of naming or labeling that is evoked by a non-verbal stimulus?

The term that describes the act of naming or labeling something in response to a non-verbal stimulus is known as a tact. Tacts are verbal operants that involve using language in a way that describes an object, event, or action that is present in the environment, thereby allowing the individual to label their observations or experiences.

For instance, if a person sees a dog and says "dog," they are tacting because they are labeling what they perceive. This is distinct from other verbal operants, such as a mand, which involves requesting something (often for a need or want), or an echoic, which refers to the act of repeating what someone else has said. The intraverbal, on the other hand, involves conversation where one response is based on a previous verbal stimulus, not tied to a direct non-verbal cue. Thus, the tact is specifically characterized by the verbal response that arises from seeing or experiencing something in the environment.
