B. F. Skinner 
Verbal Behavior 

Verbal Behavior is a 1957 book by psychologist B. F. Skinner, in which he describes what he calls verbal behavior, or what was traditionally called linguistics. Skinner’s work describes the controlling elements of verbal behavior with terminology invented for the analysis-echoics, mands, tacts, autoclitics and others-as well as carefully defined uses of ordinary terms such as audience.
