Verbal Behavior: Extended Edition. Chapter 14: Composition and Its Effects. Quote 9

The “punctuation” of written verbal behavior is perhaps the best example of compositional autoclitic behavior. It satisfies our criteria because it cannot occur until primary behavior is available to be punctuated, and it amplifies, clarifies, and modifies the effect on the reader. It corresponds, in part, to temporal and intonational patterns in vocal verbal behavior, which must also be regarded as autoclitic. Punctuation is “read” in such patterns. (p. 355)
