A verbal operant evoked by a non-verbal stimulus, involving labeling or describing that stimulus is called?

• A. Echoic
• B. Tact
• C. Intraverbal
• D. Mand

Answer: (B)

A tact is a verbal operant evoked by a nonverbal stimulus and involves labeling or describing that stimulus. When you see something in the environment and say its name or describe it—like “dog,” “red ball,” or “that bird”—your response is controlled by the actual item or event present, not by someone saying it first. This is different from an echoic, where you repeat something spoken to you, with the verbal stimulus guiding an exact imitation. It’s also distinct from an intraverbal, which responses are under the control of a verbal context or question and are not directly about the present stimulus. And a mand is a request for something you want, driven by a motivating operation. So labeling or describing what you observe fits tact.
