What does the term "tact" refer to in verbal behavior?

The term "tact" in verbal behavior refers specifically to a response made to label an item. This means that when a speaker identifies or names an object, event, or action in the environment, they are engaging in tacting. This behavior is typically prompted by a non-verbal stimulus, such as seeing an object, and serves to communicate information about that item to a listener. Tacts are a fundamental component of language development as they help individuals express themselves and share their experiences with others.

The focus of tacting is on the act of labeling and not on the function of the verbal behavior related to requesting, responding to questions, or imitation. This unique aspect of tacting distinguishes it from other forms of verbal behavior like mands (which involve requests) or echoics (which involve repetition of what someone else says).
