"...Meaning is not a property of behavior as such but of the conditions under which behavior occurs ...(this) issue is particularly important in the field of verbal behavior where the concept of meaning enjoys unusual prestige."
B.F. Skinner, Verbal Behavior, 1957.

" Language is treated as a behavior that can be shaped and reinforced while careful attention is paid not only to what a child is saying but why he or she is using language."
M. L. Barbera, The Verbal Behavior Approach, 2007.
