Chapter Five of ''Verbal Behavior'' discusses the tact in depth. A tact is said to "make contact with" the world, and refers to behavior that is under functional control of a non-verbal stimulus and generalized conditioned reinforcement. The controlling stimulus is nonverbal, "the whole of the physical environment". In linguistic terms, the tact might be regarded as "expressive labelling".  Tact is the most useful form of verbal behaviour to other listeners, as it extends the listeners contact with the environment.  In contrast, the tact is the most useful form of verbal behaviour to the speaker as it allows to contact tangible reinforcement.   
Tacts can undergo many extensions: generic, metaphoric, metonymical, solecistic, nomination, and "guessing". It can also be involved in abstraction. Lowe, Horne, Harris & Randle (2002) would be one example of recent work in tacts.<ref>{{cite journal |author1=Fergus Lowe, C. |author2=Horne, P.J. |author3=Harris, F.D. |author4=Randle, V.R. |title=Naming and categorization in young children: vocal tact training |journal=J Exp Anal Behav |volume=78 |issue=3 |pages=527–49 |date=November 2002 |pmid=12507018 |pmc=1284914 |doi=10.1901/jeab.2002.78-527}}</ref>
